General Hydroponics was founded in the mid-70s near San Francisco, California, by a group of scientists, researchers and technicians. Today, GH is recognised by the international scientific community for its reliability, the quality of its products and its sense of innovation. Within a few years, our reputation crossed international borders, extending to Canada, Australia and on to Europe, where GH Europe was established in 1995 in the South-West of France. Since the beginning our objectives have remained the same: to stay at the cutting-edge of technology, to offer the best quality of service and to bring solutions for some of the environmental problems that our planet faces today. Our technology is called “Aero-hydroponics”: plants grow without substrate, in a perfectly balanced flow of nutritive solution, saturated with oxygen. (A more detailed description follows.) Thanks to its flexibility, this alternative growing method holds an enormous potential of opportunities. It can be adapted to most situations, allowing one to grow anywhere, from the city to the most remote countryside. One of the first concepts we developed in California was the hydroponics “MicroFarm” (Family Farm) a small to medium operation that allows a family or individual, wherever they are based, to produce part of the vegetables they consume, eliminating the expensive middlemen, and eventually providing surplus to sell within the local farmers’ markets, co-ops, restaurants, etc. In our greenhouse in the South West of France, we study the potential of several high value cash crops that will give the grower an alternative to traditional crops, and will allow him to step out of the vicious circle of subsidies. We especially study the field of medicinal plants, where there exists a constant demand of quality stock, and where it is urgent today to stop the gathering of many endangered species. Our research is aimed on selecting the right species, optimising their harvest and increasing their content in active principles. Aware of the insufficiencies in the food and water supply on the planet, we participate in food development projects in the third world. Indeed, by adapting our technology to the existing resources, we teach populations a way to provide for their immediate basic needs and to create, whenever possible, an unexpected but well needed source of income. As environmentalists, when possible we utilise recycled and regenerated materials. To respond to the problem of electrical consumption, we are currently testing in California the first systems powered by solar energy. Today, after several years of intensive research, we are proud to offer you “bioponics” - or organic hydroponics - a new concept in plant cultivation (patent N° 05.11569), which combines the advantages of hydroponics with those of organic farming, while responding to the principles of sustainable development. Our line of products is vast, often unique and always in evolution. It is developed by our team of researchers, thoroughly studied, then tested in our greenhouses in California and in France. Today our products are used by growers worldwide. They are sought after by the most important laboratories in the world and NASA uses Flora Series and the AeroFlo in their studies on cultivation in their space stations.

Noucetta Kehdi and William Texier, Cal Herrmann and Lawrence Brooke, co-founders of GHE
In 1995 GH Europe was founded in South-Western France to better serve the new European market, with a range of services also covering Africa, Asia and the Middle East. Twenty years later, GHE gained a dominant position in Europe and opened a great number of markets in countries as varied as Japan, Russia, South Africa, India and Kuwait. With North America, Australia, Europe and the many countries that join us every day, GH is today a major reference on the world hydroponic market. This is, of course, especially due to the quality of our products, but also to the reliability of our technology and our unfailing commitment to the principles which always inspired us: Sustainability, quality, simplicity and innovation. Today, 40 years after being founded by Lawrence Brooke, GH has built factories in California (the west coast of the United States), in Virginia (the east coast) and in Europe (France). This enables us to be close to our markets, in closer contact with our clients, and allows us to react efficiently and rapidly. We are also able to adapt to the rules and regulations of the different countries that we serve, and to offer you authorised and reliable products. Finally, thanks to our local manufacturing, we participate in the growth of our
communities, and we eliminate a large percentage of unnecessary and polluting transportation. Over time, and because of the differences between the markets and regulations on the two continents, our product ranges in the United States and in Europe have been slightly diversified, except for Flora Series, the original fertiliser on which our excellent reputation is built and which still remains a reference of quality at the international level. To maintain the similarity of our two product lines, while respecting the regulations of different countries, we have sometimes had to offer different products with the same name. But they all serve the same objective in differing environments, and will give you the same total satisfaction. In Europe and in the United States, we also developed the first worldwide range of organic products adapted to hydroponics (which we call “bioponic“ products). Based on BioSevia and BioThrive, this range is offered under the name of “General Organics.” In Europe, all our products are tested in our greenhouse. This is also where we grow our collection, a large variety of plants from all over the world. For additional information you can see our greenhouse on www.ghe-blog.com or, if you are visiting the Gers and would like to see for yourselves, don’t hesitate to visit us in Fleurance (France).

A Technology for Today Often when discussing hydroponics we are greeted, not only by a lack of knowledge, but also with incredulity, scepticism and occasionally downright disapproval, especially when we explain that this method of cultivation consists of growing plants directly in water and plastic, rather than in soil. And yet our technology represents one of the most sensational developments in recent years. It is increasing rapidly worldwide, spreading into all kinds of projects, from vegetal walls to urban gardens and family farms of all types.
What is hydroponics? Hydroponics is the art of growing plants in water. The word comes from the Greek “hydro” (water) and “ponos” (work). The concept was rediscovered in 1930, at the University of Berkeley in California by Dr. Gericke, but in reality this growing method has existed since the earliest of times. We have all heard of the hanging gardens of Babylon, and of those people living at altitude around mountain lakes like Titicaca in Peru and Inle in Myanmar, who cultivated their gardens on water surfaces, over straw mats, water hyacinth beds or any other local substrata. In hydroponics, as in these mountain lakes, plants live over water with their roots hanging in the dynamic flow of a nutrient solution. Although plants such as rice and water lilies or carnivorous plants can adapt well in scarcely oxygenated, or even stagnant environments, most have difficulty in adapting to oxygen deficiencies. Indeed, if a plant lacks oxygen in its root zone, it asphyxiates even though it is adequately watered: actually a recurrent cause of death for houseplants is due to over watering. This is often what happens in “hydroculture” (not to be confused with “hydroponics”), a growing method with wicker buckets standing in a “dormant” nutritive solution. Thus, plants can grow in water, but not under all conditions. Water has to be “alive.” One must be aware that, whatever the environment they are growing in, be it soil, air or water, plants absorb their food in the form of ions dissolved in oxygen. In water, when food and oxygen are absorbed, they must be replaced. This is the function of hydroponics: a soil-less cultivating method which stimulates plant growth while controlling the quantities of water, mineral salts and most importantly, dissolved oxygen. The basic concept is quite simple. When roots are suspended in moving water, they absorb food and oxygen rapidly. If the oxygen content is insufficient, plant growth will be slow. But if the solution is saturated with oxygen, plant growth will accelerate. The grower’s task is to balance the combination of water, nutrients and oxygen, with the plant’s needs, in order to maximise yield and quality. To obtain the best results, a few important parameters need to be taken into account: temperature, humidity and CO2 levels, light intensity, ventilation and the plant’s genetic make-up. Essentially this is what any conscientious gardener would do.
And what are its advantages? Hydroponics can be used by a wide range of people: plant lovers in general, private or professional plant collectors, small and large greenhouse growers, horticultural societies, research centres, schools and many more. The following list is a summary of its applications and advantages: n Optimal utilisation of the plant’s genetic potential. n Better control of the plant’s nutrition. n A visible improvement in quantity and yields. n A significant shortening of the growth / production interval for a large variety of species. n A more efficient use of space. n An excellent propagation success rate. n Huge savings on fertilisers, and most importantly, on water in a situation of ever increasing global scarcity.
BRINGING NATURE AND TECHNOLOGY TOGETHER General Hydroponics Europe
total absence of herbicides. To replace pesticides and A fungicides, hydroponic growers will often use IPM (Integrated Pest Management). n T he strength and vigour of plants started in hydroponics then transplanted in soil is such that it opens enormous commercial perspectives, especially for potted plants. n In the field of education, at all stages, hydroponics fills children and adults with wonder. Several countries have already introduced it into their school or university programmes. n L ast but not least, hydroponics was, and still is, used for research purposes. For the last 70 years this method has been applied in the most important research centres because of its reliability, its precision and the broad spectrum of its applications. Thanks to hydroponics enormous advancements have been made in the understanding of plants and especially their nutritional requirements. Like all things, hydroponics can have good or bad results depending on the people who apply it and their objectives. n It can be used for mass production and to produce tomatoes with little taste or roses with no perfume. But it can grow products with the best nutritive qualities, bursting with flavour and aroma. n It can be a pollutant when used with rockwool or in run-to-waste conditions. But it can be applied ecologically in respect to the environment, sustain a large portion of the planet’s population with quality food and allow third world countries to feed their own people, even when the soil is poor and water scarce. Another recurring question: Are hydroponic crops organic? The answer is no, they are not. The mere fact that this is a soil-less operation already prohibits an “organic” designation. As for the fertilisers, there was no complete organic nutrient for hydroponics until now. In 2004, William Texier, head researcher in our European laboratories, created BioSevia, the first and only complete organic nutrient for hydroponics that complies with the European regulation on organic agriculture. Furthermore, our mineral fertilisers are so precisely crafted, that they leave no toxicity or heavy metals whatsoever in plants, when used according to the instructions. Today several variations of our technology are on the market: NFT, Drip Systems, Ebb & Flow, Aero-hydroponics. They are applied in industrialised countries like Australia and Canada, and are spreading to many Southeast Asian countries, where an increasing acreage of hydroponic greenhouses are used to grow vegetables, fruits, potted plants, cut flowers, etc. In some third world countries too, teams of volunteers are teaching people to build their own hydroponic systems from industrial scrap, and to produce fertilisers with domestic waste. Hydroponics has other applications, particularly in the field of outdoor and indoor gardening. In the US, for more than 30 years, manufacturers have been developing small-sized units for hobby gardeners, using the same technology as the greenhouse industry. Those systems are designed for the wider public and can be installed on balconies or patios and in sitting rooms and kitchens. They vary from one-plant mini-modules to small kitchen gardens. It is true that these techniques are not relevant for everyone. A common error is to think that if plants have sufficient water supplies they can be left unattended for longer. In fact, their accelerated metabolism requires greater attention. This methodology is not to save time on maintenance, rather it is conceived to maximise results. In this sense, hydroponics is intended for plant lovers and collectors, from beginners to professionals, rather than for the occasional gardener. Of course, the concept of hydroponics may appear inconceivable to some, or just another fad. Others will be curious, amused or interested. To you all, whatever your reaction, don’t hesitate to contact us to give us your opinion or to request more information. n

“3-part Building-Block Advanced Nutrient System” THE ORIGINAL 3-PART FORMULA Flora Series is the original 3-part Building-Block Advanced Nutrient System. It contains all the primary, secondary and micronutrients necessary for balanced plant nutrition, enhanced yields and superior crop quality. These nutrients form a complete and balanced fertiliser that provides plants with everything required to successfully build strong plant structures and big blooms. Flora Series is pH buffered. Flora Series is a high technology fertiliser, recognised worldwide as the most advanced hydroponic nutrient line ever developed. It is used by the most prestigious research laboratories and universities. NASA scientists refer to it as “reliable, adaptable and pH buffered.”
1976, The First Flora Series
The concept of a 3-part nutrient, and Flora Series, were created for General Hydroponics by Dr. Cal Herrmann, formerly senior chemist at NASA, in collaboration with scientists from the University of Davis in California. Dr. Herrmann is today a partner at GHE and still conducts research. Flora Series enhances the flavour, aroma, potency and essential oils of your fruits and vegetables in hydroponics and soil. It is a dynamic, evolving formula, constantly updated, and adapted to the latest scientific discoveries. Simply, it allows you to match the needs of your plant through the different stages of its life by changing the ratios between the liquids, as well as their concentration.
General Hydroponics Europe
FloraMicro® The foundation of the “Building-Block” system. FloraMicro provides the plant with all the necessary micro-elements, in a chelated form (see p. 28). It also includes sub micro-elements and organic buffers which help stabilise the solution’s pH. FloraMicro complements FloraGro and FloraBloom in secondary and major nutrients. FloraMicro is available in “hard“ and “soft“ water formulas: For water with more than 70 mg / L calcium, use FloraMicro “hard water.“ Under 70 mg / L calcium, use FloraMicro «soft water».
Stimulates structural and vegetative growth. Builds strong roots. Provides nitrogen, phosphorus, potassium and secondary minerals.
During growth it increases root formation and health. During flowering and fruiting it enables the plant to fulfill its genetic potential to the maximum. Among these three components there is perfect synergy. Flora Series is available in 0.5 L • 1 L • 5 L • 10 L • 60 L - 1000 L

FloraDuo Grow, FloraDuo Bloom concentrated liquid nutrient
THE ULTIMATE IN 2-PART PLANT FOODS FloraDuo is a “classic“ mineral nutrient with a difference (and an essential one) where each of the elements a plant needs is derived from a large variety of different sources. To create an excellent nutrient you need, of course, a precise formula. But this is not all you need! It’s also very important that each element is derived from different sources and different salts. This is how all the elements are made available at all times, in an easily absorbable form. And we don’t stop at that! We also add “bio-activators” into each bottle. These are not direct nutrients for plants, but instead they improve the plants’ general health, help them to better absorb their food and increase their resistance to pathogens and insect infestations. FloraDuo is a complete nutrient, especially designed for fast growing plants, with a marked difference between growth and flowering needs. It comes in two parts: FloraDuo Grow and FloraDuo Bloom. To guarantee the best results, FloraDuo “Grow” is available in both hard water and soft water versions. Use FloraDuo Grow “soft water” also for demineralised and reverse osmosis water. Note that the internodal distance is shorter with FloraDuo. That is accomplished through our use of purified nutrients, NOT by using PGRs (Plant Growth Regulators).
Shake well before using. FloraDuo is highly concentrated: 5 ml / L is enough for balanced and vigorous growth.
Promotes growth and structural development, as well as extremely vigourous rooting. It prepares plants for highly intensive flowering. FloraDuo Grow is available in “hard“ and “soft“ water formulas: For water with more than 70 mg/L calcium, use FloraDuo Grow “hard water.“ Under 70 mg/L calcium, use FloraDuo Grow “soft water.“

Our ethic at GHE is to promote growth and flowering by improving the nutrition of plants. Therefore, our products contain no hormones or synthetic precursors of any kind. The amazing results that you experience with our nutrients are not due to a manipulation of the metabolism of a plant, they are merely the best expression of a plant’s genetics promoted by comprehensive, holistic nutrition. General Hydroponics Europe
late flowering nutrient Ripen is a complete nutrient and can also be used as a stimulant: It increases flowering and production of active principles. It eliminates nutrient excess. Ripen is a mix of refined mineral salts and buffers, formulated by our laboratories with the greatest precision. Indeed, at this stage, accuracy is of the utmost importance. The plant, at the end of its life, is generally more fragile and the assimilation process is greatly reduced when compared with the vegetative phase. Ripen acts at different levels: It gives the plant a strong signal that it is coming to the end of its life. The plant reacts by speeding the ripening process, in a last effort to spread its genes. It forces the plant to strengthen its defences and thus increase its active principles. It delivers all the mineral salts the plants need in a form easy to assimilate. In case of a previous accumulation of nitrate or microelements, it helps metabolise these residues, which will improve the taste of the crop.
Ripen is a “forcing solution.“ It is designed to accelerate plant ripening, improve content in active principles, and eliminate mineral salt residues. To achieve best results : use the last 10 days Hydro Hydro : EC = 2.4 - 2.8 - Soil : EC = 2.2 - 2.6 Ripen is a powerful nutrient. Adapt those EC to the variety of your plant and its growing conditions
Ripen has many properties: Outdoors, it enables you to quickly harvest a crop before it is spoiled by cold and damp weather. Indoors, it helps you harmonise the end of the grow cycle by speeding up the ripening of the slowest plants. In case of a severe infestation of fungi or insects, it allows you to accelerate the natural cycle and get something out of a crop that would otherwise be completely lost. It allows metabolisation of mineral salts excess. It increases the active principles in medicinal plants. Ripen is available in 0.5 L • 1 L • 5 L • 10 L • 60 L • 1000 L
The Tripack Starting Kit 1/2 L Ripen is added in the FloraDuo and FloraNova Tripacks

It contains fulvic and humic acids which improve soil conditions and enhance the plant’s absorption capacity. It contains amino-acids. It is efficiently applied in fertigation and drip irrigation. It brings a sweet, pleasant taste to your crop. It works in soil and also in hydroponics!
BIOSEVIA® IS A "BIOPONIC" NUTRIENT BioSevia gives perfect results in soil but uniquely works beautifully in hydroponics too, be it with bare roots or on substrates. No other nutrient is adapted to this type of growing. Generally, organic nutrients are formulated in order to slowly decompose in soil, so when in water, some of their elements will rot and release quite unpleasant smells. They would also clog filters and drippers. To be bioponic, a nutrient must be liquid and perfectly soluble. It must be rapidly degradable and readily available to the plant. BioSevia accomplishes all these conditions. BioSevia Grow and Bloom are very concentrated: 2 ml / L are enough for a complete and balanced plant nutrition. BioSevia is available in 0.5 L • 1 L • 5 L • 10 L • 60 L
Feeding charts for bioponics are available with each BioSevia product (see page 53). 16

bioponics BIOPONICS (or organic hydroponics) patent N° 05.11569 - 15/11/05
BM (Trichoderma harzianum) micro-organisms: bioponic mix
BioSevia works perfectly in soil. We recommend using a small amount of BM (1g / 10 L) every 6 to 8 weeks to facilitate the decomposition of organic matter and to enhance growth performance. In hydroponics, it is essential to use BM to recreate the decomposition process in the nutritive solution that would happen naturally in soil.
M is only used to breakdown organic B matter. I n hydroponics, do not use Mineral Magic with micro-organisms. See page 27.
BM is available in 10 g • 25 g • 50 g • 100 g • 250 g •1 kg • 5 kg
BM conforms to the European regulation 2008/113/CE on organic agriculture. It is registered in Germany under: BBA Nr LS 004987-65-00.
BioSevia and Bioponics Bioponics or ”organic hydroponics” Bioponics creates everything that a plant needs in the nutritive solution for perfect growth. For many years researchers of several countries have been looking for an efficient way to achieve real organic hydroponics. It was William Texier who in 2004 discovered and adapted the concept of bioponic growing, the new method for an organic hydroponic cultivation. Patent N° 05.11569 - 15/11/05. Bioponics goes much further than just a change of nutrients. The concept is “liquid earth.” BioSevia, the appropriate nutrient, was the missing link. By combining it with BM, bioponics creates everything a plant needs in the nutritive solution. The water is present, of course, and oxygen too, especially if the growing system is well designed. You need to add: BioSevia: the nutrient that brings the humus fraction of soil, and which contains a wide range of large organic molecules to reproduce the complexity of soil in the nutritive solution. It is specially designed for this utilisation (to recreate the natural fertility conditions of soil, but without soil). BM (or ”Trichoderma harzianum”): the micro-organisms which bring microbial life and participate in the carbon cycle. How to manage the micro-organisms? In water, the life conditions of micro-organisms are not very comfortable, as they lack the buffering capacity of soil that protects them against sudden fluctuations in temperature or pH. They also need to be ”fixed into a substrate,” and cannot survive and propagate in water alone. They need a highly oxygenated and wet habitat. If they dry they’ll die! There are two possibilities: On humid substrate like coco fibre, rockwool or perlite, simply sprinkle BM directly on the substrate. On bare roots or in draining substrate like clay pebbles or lava rock, use a biofiltre. Biofiltres provide your micro-organisms with the correct environment to live in and develop (see p. 19). Use 10g/100 L of nutritive solution. Add every six to eight weeks. Wherever they are, in a biofiltre or directly in the substrate, the micro-organisms will happily thrive as long as their environment is oxygenated and humid. To guarantee good development, it is imperative to avoid any sudden changes, especially in temperature and pH levels. The happier and more abundant your BMs are, the better fed your plants will be! eurohydro.com
BIOPONICS (or organic hydroponics) patent N° 05.11569 - 15/11/05 BioSevia conforms to the European regulation CE N° 834/2007 on organic agriculture
How to manage bioponics Managing bioponics needs much more attention than a traditional hydroponic growing method. Not in terms of time spent, but in terms of “visual attention and examination”. Bioponics is managed by eye as much as with pH and EC parameters, although these do still remain important references. Here are a few basic notions to guarantee your success when growing bioponically. Also use the feeding charts given with BioSevia. pH level BioSevia has an almost neutral pH. It will not affect your water. During cultivation, the pH is more difficult to stabilise than in mineral hydroponics because (the somewhat quite arbitrary!) organic regulations prohibit the use of some extremely efficient buffers. This means the pH will tend to rise. But the pH doesn’t have the same importance in bioponics. It can rise up to 7.5 with no problem. Over 7.5 it has to be driven slowly down to 6.0, but progressively, over a period of five to six days. To do so, use GHE’s liquid pH Down, as it contains organic buffers and adapts well to BioSevia. (Note: GHE’s pH Down is not an organic product.) Add your regulator slowly, little by little, and dilute it well each time. Pour it into the reservoir, far away from the pump (or switch the pump off ). This will help to avoid plant stress due to a rapid a change in pH levels. Absolutely avoid: chlorhydric and acetic acids (vinegar, etc).
A significant drop in pH is an alarm bell that indicates the death of a large quantity of micro-organisms. In this case it is important to find the cause, treat it, and replenish micro-organisms.
Conductivity This is the most complex part of the bioponic process because organic molecules don’t carry electric charges, and therefore, are not read by your EC meter. When you dilute BioSevia in water, only a small fraction is immediately dissolved and transformed into ions, resulting in very little conductivity. On day one, with a dose of 15 ml / 10 L added to normal tap water, you will obtain a reading around 0.65 (0.6 to 0.7). This low conductivity is generally enough. After this period, only add nutrient when your EC goes under 0.8. At that stage add 20 ml / 10L. Keep your conductivity under 1.0 and above 0.8. Use this dosage without changing the nutritive solution, if possible, to maintain all the benefits of the environment you have already created. While nutritive elements are liberated, others will be absorbed by the plant, and conductivity will tend to remain in balance around the same values. When the stock of organic matter becomes insufficient, EC will drop. It is time to add more nutrient. This looks simple, but to obtain the best results, it is important to anticipate this drop in EC, and ensure the constant availability of organic matter. Do not add too much nutrient at once as the breakdown of molecules happens according to room temperature. In fact, micro-organisms act at radically different velocities depending on temperature fluctuation in the nutritive solution. If there is too much organic matter in the solution, a rise in temperature could increase conductivity to a level that will harm your plant. It is not always easy to find the correct balance. This is where the grower’s eye will make the difference!
Important note for organic farmers: Agencies certifying organic produce do not recognise hydroponics as an organic means of cultivation, even when you use BioSevia. Soil is the basic criteria for an organic certification, and as we all know, hydroponics does not use soil as a substrate. This is why growing hydroponically will not be considered as organic, and hydroponic crops will not be given an organic certification.

bioponics BIOPONICS (or organic hydroponics) patent N° 05.11569 - 15/11/05
Filtration Filtration is very important, especially in hot weather conditions, and when working with bare roots that hang directly in the nutritive solution. It is indeed necessary to filter the largest particles, as they could asphyxiate the roots, particularly in hot weather. It is always better to have only easily assimilated ions in the root zone. With BioSevia, a simple foam filter on the pump’s input is enough. It will not clog the filter. But still, thorough and regular filter maintenance is required. Rinse once a week for best results. Make sure you stop your system while cleaning. The plant’s environment The environment must be adapted to the plant, independently from the growing method you use. Temperature, humidity, cultivation cycle, prevention and pest control, must, of course, be adjusted to your plant’s needs.
MICRO-ORGANISMS AND BIOFILTRES ON BARE ROOTS For those who would like to keep using biofiltre, the best is to buy them from pet and fish stores. Here is a link (among multiple others) that may help you recognize the size and kind of filtre best adapted to the volume of your reservoir. In English: http://www.petsmart.com/fish/filters/cat-36-catid-300088 In French: http://www.aquariophilie.org/articles/Complement-technique-filtration-part-2-175.html ■ For bioponics growers: With more than 12 years using bioponics, we now know that micro-organisms start growing and thriving along with the growth of the roots. So, as soon as the root mass starts forming, you can innoculate your microorganisms into your systems, sprinkled on top of each netpot. You can also germinate your seeds and root your cuttings in coconut pellets, and place them in your netpot and directly into your hydroponics system. At that stage, simply sprinkle the micro organisms on top of the pellets, they will live there and then colonize the root system when it is ready. ■
i ADVANTAGES OF BIOPONICS Bioponics is founded on one of the very basic principles of sustainable, organic agriculture. This consists of giving small quantities of nitrate to the plant in order to increase flowering and fruiting rather than producing abundant, but sometimes useless, vegetative growth.
Tomato roots grown in an AeroFlo with BioSevia and BM.
Indeed, this is one very interesting aspect of bioponics. You create very little vegetative mass compared to yield. For the same yield, 1 kg of tomatoes grown in bioponics would produce a much lower volume of leaves and stems than 1 kg of tomatoes grown using classic hydroponic (and even soil) methods! This makes bioponics a very economical way to grow, as water and nutrient consumption is very much reduced in comparison to any other form of cultivation. Bioponics combines the advantages of hydroponics with organics. It helps to save water and nutrients and grow good quality, organic crops in smaller areas. However, it does not allow you to obtain an organic certification for the products you grow. eurohydro.com

DIAMOND NECTAR® natural bio-stimulator
Diamond Nectar is an exclusive fulvic acid extract from a combination of unique Leonardite sources providing the highest availability and diversity of these bio-active plant compounds. It is a stimulator for all stages of plant growth. Millions of years ago, prehistoric plants and animals were consumed in the ecological cycle of life. Buried thousands of feet deep and converted to carbon, some of these deposits produced “Diamond.” Others were pushed to the surface during the ice ages and became what is known as “Leonardite.”*
Thanks to its leveling and chelating action, as well as its important ionic exchange capacity, Diamond Nectar: increases the size of the root system, and therefore improves absorption of the nutritive elements. transports nutrients to all plant parts: roots, stems, foliage, flowers and fruit. affords growers the benefits of natural organic matter in a liquid form. In hydroponics and soilless cultivation, Diamond Nectar helps to create an environment closer to soil conditions. Diamond Nectar is available in 0.5 L • 1 L • 5 L • 10 L • 1000 L
* The General Hydroponics research team has analysed over 300 different Leonardite sources around the world to create a proprietary, pH balanced, fulvic acid with maximum agronomic benefits. Beneath some ancient lands in New Mexico, an extraordinary Leonardite deposit was formed. It contains the riches of natural organic matter composted for millennia and freely available to growing plants. This deposit is carefully mined and natural compounds called “Humates” are extracted. Soluble Humates (the humic and fulvic acids family) contain a myriad of natural plant growth promoting compounds plus nutrient enhancing ingredients. Diamond Nectar is not a fertiliser. It is an additive to be used in combination with comprehensive nutrients like Flora Series, FloraDuo, FloraNova, Flora Coco, Maxi Series and BioSevia. Combined with a conventional nutrition programme, it leads to earlier harvests, healthier disease resistant plants and enhanced qualities of flavour, fragrance and essential oils, plus significantly higher yields. Apply Diamond Nectar to all cultivated plants, including ornamentals, culinary and aromatics, fruit and vegetables, trees etc. It is adapted to hydroponics and soil. Pour directly into the reservoir or use as a foliar spray.

MINERAL MAGICÂŽ organic natural additive
Silicate is an essential element for higher plants, especially when growing with water as a substrate. Mineral Magic contains ancient sea-bed deposits of biologically transformed organic matter, plus naturally formed silicic acid clay.
ineral Magic provides a naturally soluble form of M silicon which enters plant cells and builds a hardened shield against disease and insect attack. M ineral Magicâ€™s natural colloids improve cation exchange capacity to nutrient solutions. This enhances nutrient
S tabilises nutrient solution pH and conductivity which reduces stress for rapidly growing plants. Protects against toxicity of metals. L ast but not least, Mineral Magic also contains more than 60 minerals, which add more nutritive elements for plants to thrive on. Mineral Magic is available in 1 L â€˘ 5 L
IMPORTANT NOTICE : MINERAL MAGIC AND MICRO-ORGANISMS: In hydroponics, avoid using Mineral Magic with the microorganisms (BM). It is counterproductive since in water, silicate dissolves into silicic acid, which slows the development of beneficial colonies. Conversely in soil, when mixed in powder form, the large range of elements included in Mineral Magic stimulates the growth of beneficial micro-organisms, and helps create a natural environment for extremely healthy plants.
Mineral Magic is an organic product. Use as a natural additive to the nutritive solution. eurohydro.com
comprehensive mix of micro and sub-micro elements Bio Essentials is a unique product: it is a comprehensive concentration of micro-nutrients in a chelated form, plus essential sub-micro particles and an organic buffer. It is used as a complement to the nutritive solution in soil and water culture, as well as in foliar spray. Micro and sub-micro nutrients are essential trace elements that a plant needs, in conjunction with primary and secondary elements, for a comprehensive and harmonious diet. Some of them are required in such minute quantities (the sub-micros) that they are not included in most nutrients on the market. However, laboratory tests have demonstrated an important overall improvement in a plant’s health and resistance to pests when those elements are added.
All the elements included in Bio Essentials comply with the European regulation on organic agriculture. Bio Essentials can therefore be used in organic gardening.
B’Essentials is a common denominator to comply with some of the European administrations
ABOUT CHELATES: All the elements included in Bio Essentials are chelated. A chelated element is released to the plants only when it becomes less abundant in the nutritive solution. This way, the chelate not only maintains a stable level of the nutrient, but it also protects the plant from an unwanted accumulation of harmful salts. hen plants are rapidly growing, they absorb a lot of W elements from the solution, and this destabilises its pH. The faster the growth, the wider the imbalance. This is why it is essential to have a good quality buffer that helps stabilise the pH. In the same process, the buffer will also help to control the level of calcium in the solution. An important feature in the case of hard water. Bio Essentials is available in 0.5 L • 1 L • 5 L • 10 L
Use Bio Essentials as a complement for all nutrients (liquid and dry) except with GHE products that already contain all of its elements. General Hydroponics Europe
FLORAKLEEN® salt deposits clearing solution
FloraKleen is a clearing solution unique within this industry. It can be used at any time throughout the plant’s life. FloraKleen is formulated to remove fertiliser residues that can accumulate over time in hydroponic systems, growing media and potting soils. It is safe for use in all systems and media while plants are growing. It can also be used between crops to clean accumulated salts from the systems. Contrary to other products on the market, FloraKleen is not enzyme based, and uses a completely different technology. Its high concentration and low price make FloraKleen the economical choice for maintaining your plants in both hydroponics and soil based environments.
During cultivation, FloraKleen: d issolves accumulated fertiliser salts. r educes plant stress from excess and imbalanced nutrients. b reaks nutrient bonds that attach fertiliser salts to growing media, therefore correcting nutrient lock-out. n ourishes the microbial life in the substrate. Use FloraKleen each time you purge your hydroponic system or potted plants from excess salts that can accumulate as a result of regular fertiliser application. FloraKleen is also an excellent final flush: Use it a few days before harvest to terminate maturation and promote sugaring.
APPLICATIONS: Hydroponic systems When changing nutrients: Mix 1.5 to 3 ml / L of water. Use a milder solution for young or fragile plants, and a stronger solution for more established plants, close to harvest. Re-circulate in your system for 24 hours with FloraKleen alone before adding your nutrients. Final flush before harvest: 1) A lone - Drain old nutrient solution and discard. Refill hydroponic reservoir with fresh water and mix 3 ml / L of FloraKleen. Run this solution during the last day or two before harvest. 2) After Ripen* - Add 3 ml / L of FloraKleen during the last two days before harvest to increase the sugars level in your crop. Potting Soil & Soilless Mixes 1) A lone - Every fifteen days fill a watering can with fresh water and add 1.5 to 3 ml / L of FloraKleen. Drench until there is runoff from the bottom of the pot. Resume your regular fertiliser schedule with the next watering. 2) After Ripen* - Add 3 ml / L of FloraKleen during the last two days before harvest to increase the sugars level in your crop. * FloraKleen and Ripen work together in perfect synergy. FloraKleen is available in 0.5 L • 1 L • 5 L • 10 L eurohydro.com
pH REGULATORS This unique concept of pH control allows you to adjust and stabilise your pH level, even in presence of fast growing plants.
pH Down is not an ordinary acid, but an exhaustive, complex and precise formula. The acidity and alcalinity levels of a nutritive solution have an important impact on the solubility of mineral salts, and the capacity of plants to absorb them. There is no such thing as an ideal pH. A high range favours cation intake and a low one favours anion intake. So every chosen pH is a compromise. The usual safe range recommendation is from 5.5 to 6.5. Our advice is to stay on the low side: from 5.5 to 6.2 (see p. 47-48). pH Down includes organic regulators Unlike the pH regulators generally available on the market, pH Down is not a common acid. It is a precise formula that regulates, feeds and buffers your nutritive solution all at once. Together with a balanced blend of acids, we incorporated organic buffers to stabilise pH and help control calcium in hard water situations. Use it when preparing the nutritive solution to reduce the pH level. Thanks to its buffering capactiy, the level will remain stable until you renew your solution. Adjust it from time to time to keep good control of pH. pH Down is available in 0.5 L • 1 L • 5 L • 10 L • 60 L
pH Up pH Up contains silicate To raise the pH level this solution is especially useful to growers using Reverse Osmosis or demineralised water. pH Up contains silicate to improve your plant’s environment.
Silicate deficiency can be a limiting factor in hydroponics. Because of its low solubility, it is difficult to put enough of it in the solution. This is why we incorporate it in our products wherever we can. pH Up is available in 0.5 L • 1 L • 5 L • 10 L
Use your regulators from seedling to harvest. pH Up and pH Down are adapted to all stages of a plant’s life. General Hydroponics Europe
Dry pH Down powder form
A unique product in the industry: harmless as long as it is dry, it becomes a potent acid when diluted in water. pH regulation is an essential practice for all growers. It makes mineral salts available and stabilises chelates. Two primary conditions for a good absorption of nutritive elements by a plant (see p. 47-48). To do so, different brands of acids are manufactured in the industry. Some of them are highly concentrated and can be dangerous, depending on their formulation. In several countries, such as Switzerland, the law restricts the sale and handling of these products. In order to sell them, a retailer is submitted to a series of mandatory requirements. Moreover, for shops who offer mail order, sending liquid acids by post is a risky matter, sometimes restricted by the postal authorities.
The first application of this product is, of course, pH regulation. But due to its strong concentration and high phosphoric acid content, it can be used to disinfect and clean growing systems, irrigation lines and substrates. At homeopathic dosage, it can be used as a foliar spray after an insecticide treatment to clean the leaves while feeding the plant. Dry pH Down also brings a certain amount of essential nutritive elements to a plant, during its entire lifecycle: N itrates in a form slowly assimilated by a plant and harmless to the flowering process. P hosphates for flowering and also for healthy roots, lush foliage and harmonious growth. P lus some magnesium, sulphur and micro-elements. Dry pH Down is available in 25 g • 50 g • 100 g • 250 g • 500 g • 1 kg

In 1990 at the White Owl WaterFarm (Sebastopol, California), General Hydroponics created the concept of the «Hydroponics Family Farms»: as opposed to the rapidly developing industrial food production, we had the vision of a family or community garden, producing local, fresh, nutritious and traceable food; a microfarm as it existed traditionally - using hydroponics instead of soil. Why hydroponics? Of course, to take best advantage of space in cities and coutryside, as land becomes expensive and scarce everywhere, especially a productive one. To obtain better yields and feed an ever-growing world population. To produce nutritious food, significantly reduce water consumption, eliminate pollution of soils and waters, and participate constructively in the economical and social life of our communities. For this purpose, we built the AeroFloPRO (AFPRO). Meanwhile General Hydroponics h.ad already created Flora Series in 1976. Indeed Flora Series is the first 3-part nutrient system specifically adapted to hydroponics: complete, concentrated, adaptable, and highly soluble. Its building-block structure allows it to closely respond to the plant’s needs at all times, and helps it develop the best of its genetic potential. Strong with 40 years immersed in plant nutrition and cultivation, we are able today to offer you the most dependable, efficient, and cost-effective line of hydroponic systems, nutrients and supplements.

The Hydroponics Family Farm THE NUTRIENTS AND SUPPLEMENTS Very often, when we meet with professionals from the soil gardening industry, they look at our product line in disbelief. They never thought it useful to give such exhaustive and exclusive diets to plants. A few years, and still now most greenhouse growers buy powdered mineral salts of different qualities, mixing and distributing them with the help of a simple program. But nowadays, to adapt to an increasingly demanding public for healthy food, growers find it easier to count on a dependable manufacturor, and insure nutritious and bountiful crops. Because they gain in dependability and productivity, and therefore time and money. BIOPONICS - ORGANIC NUTRIENTS

AQUAFARM® AND WATERFARM® An excellent introduction to hydroponics
Often copied but never equalled, these two systems provide top performance while being reliable, easy-to-use and inexpensive. The AquaFarm is the first hydroponic “home unit,” created more than 30 years ago by GH founder Lawrence Brooke in California. Since 1975, thousands of these remarkable units have been sold worldwide, bringing satisfaction to their owners and growing thousands of beautiful, healthy plants. These pots have several applications: in nurseries or indoor gardens for mother plants and collectibles; in the house for decorative or culinary plants of all sizes; in the kitchen for aromatic herbs to use fresh while cooking. They are used in research laboratories and universities and even in schools where studying plants growing hydroponically fills children and adults with wonder. You can place them everywhere, in a sitting room, an office, a veranda or a greenhouse.
Plants are grown within a chamber filled with clay pebbles. The growing chamber is suspended above a reservoir filled with nutrient-enriched water. An air pump drives the nutrient solution up through the “pumping column,” to the drip-ring, where it then drips down through the clay pebbles. This infuses the nutrient with oxygen and constantly bathes the roots, stimulating the plant to grow like you have never seen before! Technically similar to the AquaFarm, the WaterFarm differs only in size and price.
Your first aero-hydroponics system Have you ever wanted to try aero-hydroponics but failed to find a simple and economical solution? Well, now it’s possible thanks to the AeroFarm (2” and 3” versions). Seven good reasons to try it: 1. The AeroFarm fits perfectly into small growing areas. 2. It has a large reservoir capacity and easy access to the nutritive solution. 3. Like the AquaFarm and the WaterFarm, it is practically indestructible. It is made with heavy duty recycled plastics, and includes a barrier against light and UV to prevent algae from growing in the reservoir. 4. It holds one to five plants and can be used for mother plants as well as complete crop cycles. 5. It is very easy to assemble, clean and maintain. It is user-friendly and comes with a set of detailed instructions. 6. An AeroFarm means NO MORE SUBSTRATE to move up and down and to discard. Simply use the plastic net-pots with a minimum quantity of recyclable clay pebbles. 7. If you already have an AquaFarm and wish to try aero-hydroponics, keep your reservoir and simply buy the AeroFarm conversion kit. 36

growing systems Using the EBB&GROW® you can grow using clay pebbles (Grorox), coir or a coir/perlite mix, soil, and rockwool (which we do not recommend as it is non recyclable)
The Ebb & Flow system uses sub-irrigation; the nutrient solution floods the substrate and then runs off into the tank when the pump stops. This regular ebb and flow of the solution provides the root system with excellent oxygenation. This type of system is designed for beginners who are looking for a technically simple system that is easy to use, and for experienced growers who are looking for a modular system that can adapt to the specifics of their growing environment that truly maximises the yield. It is the very definition of the versatile growing system: it allows the use of a wide variety of containers (size, material, shape) and substrates or substrate mixes (clay beads, coir, perlite, soil). To complete the list of this system’s advantages: • It has no risks of leakage or overflow all with minimum maintenance. • Its autonomy allows you to leave it unattended for a few days without any risk to your plants. • It is easy to clean. Why we are proud of the EBB&GROW®? • .EBB&GROW® is manufactured in France in our workshops from 100% recycled* plastic using a process that gives it unrivalled strength. We are the only company on the market to offer a LIFETIME GUARANTEE** for moulded plastics (Tank and growing table). This does not add anything to the price. • Its compact design makes it possible to hold up to 32 15x15 cm plastic pots or 22 fabric 1 Gallon pots (3.75L) without any space loss. •. It withstands the weight: the tank supports the centre of the growing table. This is why the upper tray does not warp. • .Low system: As the system is only 38 cm high, it leaves your plants enough space to grow. • High capacity tank: Up to 100L of solution. • Very low electricity consumption: 6.5 Watts * Production using 100% recycled plastic can cause slight colour variations in the product depending on our raw material supplies. ** We offer the LIFETIME GUARANTEE for rotary moulded parts (Tank and growing table) except for damage resulting from abnormal use of the equipment, negligence or attempts to alter the product. Timer An ebb and flow table requires to use a timer (not included) that regulates the irrigation cycles. For irrigation cycles of less than 15 minutes, you should choose a digital timer that supports minute by minute programming.
The EBB&GROW includes a free set of Flora Series 1/2L.
A word from the designer: In “Hydroponics for everyone” (Mama Editions, Paris, France), William Texier describes the ebb and flow table as an “excellent technology that works wonders. It respects the basic rule of hydroponics: root system oxygenation. By slowly raising and lowering the water level, the ebb and flow system provides excellent oxygenation, which is essential to all good systems. When it rises, the water flushes the spent air from around the root area and renews it when it drains away.” (p. 51) 40

Expanded clay pebbles Grorox are a safe, renewable and ecological product made out of natural clay. They are porous and provide good drainage and excellent oxygenation is the root zone. They are a clean, neutral, light and recyclable substrate. Used correctly, Grorox is an integral part of any successful hydroponics garden. Before using: • It is important to thoroughly rinse your pebbles to remove any sand and wash off all remaining residues. • It is recommended that you always check the pH level. Put some pebbles in a glass of water with pH adjusted to 6.0. Stir well, let it rest, then measure. If the level is high (7.0 or higher), soak the pebbles overnight in a solution of phosphoric or nitric acid (or pH Down liquid or powder). Then rinse thoroughly before using. If your Grorox are neutral, wash thoroughly and rinse well. After the crop: • For reuse, it is generally sufficient just to wash off all organic debris and rinse well. • I f needed, in case of insect or mould infestation, it is recommended to disinfect the pebbles. To do so, soak overnight in a strong acid solution (or pH Down - at 4.0). Before reuse, rinse thoroughly to ensure the acid is washed away.
Grorox Ø 8/16 mm
A great advantage to using Grorox is that, unlike rockwool, it is harmless, reusable and non-polluting. It is natural and can be used several times, from crop to crop. Recycle it in your garden, it is biogegradable and will lighten the soil. eurohydro.com

The essentials of successful gardening Genes
The genetics of your plants will play a major role in the outcome of your garden. As the plant goes through its life cycle it can sometimes be difficult to assess whether it is responding to its environment, or whether it is following the instructions written in its DNA. With the rise of genetically engineered crops, the choice of which varieties to grow can become a charged issue. We have an ethic at GHE, which is to promote growth and flowering by improving the nutrition of the plants. Therefore, our products contain no hormones or synthetic precursors of any kind. The amazing results that you experience with our products are not due to a manipulation of the metabolism of the plant, they are merely the best expression of its genetic make-up promoted by comprehensive, holistic nutrition.
Atmosphere The atmosphere affects the growth and life of plants dramatically. Plants require lots of fresh air, so growers who are using greenhouses and indoor facilities must supplement their airflow with fans. The temperature and relative humidity have a major effect on plant physiology and growth. Both photosynthesis and transpiration are dependent upon proper humidity, temperature and air circulation. Plants can survive in a wide variety of atmospheric conditions, but to truly thrive they must have plentiful fresh air and proper temperature and humidity. The ideal temperature and humidity for your plants is between 18 and 32Â°C and 40% to 80% relative humidity.
Light The amount and quality of sunlight that your plants receive will also affect their growth. Seasonal variances, exposure and shadows from buildings and trees must be taken into account when setting up a garden. If artificial light is to be used, it must be of a robust spectrum and sufficient intensity to satisfy the needs of the plants without overwhelming them or drying them out. Different plants and different phases of growth require different light spectra and intensity. Light supplies the energy used in photosynthesis, which is one of the most fundamental plant processes.

Insects Unfortunately for gardeners, there are a host of organisms which survive by destroying plants. These range from microscopic bacteria, viruses and fungi to larger organisms such as insects and arachnids. Cleanliness can help prevent pests from arriving. By keeping garden tools and surfaces sterilised, destructive micro-organisms will have a harder time gaining a foothold. Moist, warm and damp conditions are favourable to developing mould and mildew, so avoiding condensation and ensuring sufficient air circulation will help keep these undesirables away. Larger pests require a more aggressive approach. There are many products available which assist in the eradication of these invaders, but cleanliness is a good start in managing pathogens and pests. Used as preventatives, products like BioProtect (that stimulates the immune system), Mineral Magic (that strengthens the plant structure), or Urtica (that kills an amazingly wide range of insects) are very efficient in improving plant resistance. There are also integrated pest management (IPM) techniques which use natural predators to fight harmful insects. The effectiveness of IPM is now well proven.
Nutrition Plants need nutrients to grow. GH has several nutrients which provide all of the elements required by plants. These fertilisers contain an ideal blend of macro and micro nutrients, and can be adjusted to suit the needs of the plant based on its age and growth stage. To boost plant performance, successful gardeners add supplements to the nutrient solution. These additives can improve plant vitality, enhance flavours and increase yields. Since these nutrients and supplements are absorbed through the roots of the plant, optimum nutrition requires strong and healthy roots. Proper nutrition is a major component of healthy, thriving plants.
Water The quality of the water that plants receive will affect their health and vitality. Tap water can contain harmful additives, such as chlorine, and even natural well water can contain an excess of minerals or have an extreme pH. A surplus of many common elements in water can cause a chain reaction in a nutrient solution, resulting in many of the vital elements fusing together and becoming unavailable to the plant. Testing your water will inform you if your water is an issue. If your problem is excessive minerals, using the hard water versions of our nutrients might be sufficient. Truly problematic water must be filtered and pH adjusted before being used for plants. To know the quality of your water, ask for an analysis from your water supplier. 46

Nutrient strength and meters
Heat and nutrients
Nutrient strength is a key factor in proper plant nutrition. Although the recipes GH provides you with should create nutrient solution at the proper strength, there are many environmental factors which can cause nutrient strength to change. A nutrient strength meter is an essential tool for the advanced grower. There are two different types of meters which measure nutrient strength - PPM and EC meters. Both types make the same measurement, but then present the result in different units. Nutrient strength is measured by passing an electric current through the solution; the more easily electricity travels through the solution, the stronger it is. An electrical conductivity meter (EC) will give this result as an electrical value, such as a milliSiemen (mS). This number is directly related to the strength of the nutrient. PPM meters measure the conductivity of the solution, and then attempt to estimate the actual parts per million. The problem with this method is that different meters may use different scales to convert EC measurements to PPM readings, so two different PPM meters could read drastically different values in the exact same nutrient solution. In Europe we use EC meters, which simplifies things a lot. Whichever meter you choose, it is very important to use a measuring device, in order to track changes in nutrient strength and make decisions and adjustments which will contribute to success.
Arid, bright, hot environments can have an impact on nutrient solution. As the solution loses water through evaporation and plant transpiration, nutrient strength increases. When growing conditions are more intense, using a less concentrated nutrient solution and monitoring nutrient strength with a meter can help prevent overfeeding. As nutrient solution becomes warmer in hot weather, it loses its ability to hold dissolved oxygen, which is essential for root health. When hot weather strikes, monitor the solution temperature and keep it below 24°C or use a BioFiltre.
Digital meters: EC & pH Electrical meters are a fast way to control EC and pH. To make sure your meters remain accurate regularly test them with calibrating solutions.
Quick tips for reverse osmosis users: For those who use reverse osmosis filters, here is a great tip to buffer your water and help stabilise the pH. There are two ways, and both are efficient: • If you prefer simplicity, all you have to do is add 20% tap water to your reverse osmosis water. • If you are a purist, and do not want to use tap water, or whose water is particularly bad, here are two easy steps: 1. First increase your pH up to 10.0 with pH Up or potassium carbonate. 2. Then bring it down to 6.0 with pH Down. In both cases you’ll obtain water well adapted to hydroponic nutritive solutions, while avoiding untimely pH fluctuations.
Use our pH adjusters to raise or lower pH as needed. Adjusters are available in liquid form (pH Up & pH Down) or in powder (Dry pH Down). Add regulators gradually to avoid overshooting. eurohydro.com
GHE advanced growing advanced techniques growing techniques
pH and nutrient availability The pH of a nutrient solution describes its acidity or alkalinity. Although extremes of pH can damage roots, the primary reason that pH is relevant to growers is that it affects whether certain elements in the solution are available to the plant or not. Specific nutrient deficiencies can arise in a well balanced nutrient solution if that solution exceeds the optimum pH range. Therefore, it is beneficial to your plants to monitor and adjust pH as needed to ensure complete nutrient availability. Many factors work to change the pH of your nutrient, including microbial activity, atmospheric interactions and recirculation. For best results regularly check pH to ensure that it does not exceed the acceptable range. Keep nutrient pH between 5.5 and 6.2.
Liquid pH testers A liquid pH indicator is the most reliable and economical way to check your pH level. With a liquid pH test indicator, you can also regularly validate the accuracy of your pH meter, and make sure it is working properly. Remember, it only takes a few hours to kill a crop if your digital meter gives you an incorrect reading.
Add two drops of liquid pH Indicator to half a tube of nutritive solution. Compare with the colour chart provided to identify your pH.
General Hydroponics Europe
Deficiencies Hydroponic nutrients contain all elements needed by plants. Under normal circumstances, all elements should be available and nutrient deficiencies will not occur. A pH imbalance can cause nutrient deficiencies by creating mineral interactions. Hard water or incorrectly mixing nutrients directly together will also contribute to pH problems. If you observe signs of a specific nutrient deficiency while using high-quality nutrients, examine environmental factors first.
Why use hydroponic nutrients? In soil or in hydroponics, hydroponic nutrients provide the ultimate in comprehensive and customisable plant nutrition. Providing superior results in both soil and hydroponic gardens, hydroponic nutrients are mineral-based plant food which provide complete and total plant nutrition. Because hydroponic systems do not use soil, they rely on the nutrient solution to provide all the elements needed by the plants. As a result, hydroponic fertilisers, unlike most commonly available plant food, must contain the entire spectrum of necessary elements, making them a robust and complete nutrient source suitable for all gardens.
Typical Fertiliser: Unsuitable for Hydroponics This fertiliser only provides partial nutrition and must be combined with other fertilisers and soils to provide complete nutrition. (In this case we recommend using Bio Essentials.
Hydroponic Nutrient: Full-Spectrum Plant Nutrition In a hydroponic system or in soil, this fertiliser will ensure that everything the plant needs will be right at its root-tips.
The nutritional needs of your plants will change throughout their lifetime. A seedling needs a completely different nutrient than a flowering or fruiting plant, and due to their precise composition and modular components, hydroponic nutrients can easily be tuned to match the needs of a plant at any stage of growth. In addition to supplying complete nutrition, hydroponic nutrients are also easily customisable and adjustable to match the changing needs of your plants.

the role of supplements
The role of supplements In soil and in hydroponics, supplements add essential qualities to the diet of your plants. Although a properly mixed, high-quality, hydroponic nutrient will provide everything a plant needs to thrive, plant performance doesn’t end with supplying just the necessities. Plants cannot live without nutrients, but nutrients alone will not unlock their full potential. Even though supplements may not contain “food” for a plant, they improve a crop by performing such functions as introducing essential organic compounds, accelerating nutrient uptake, boosting flowering, protecting the root-zone, activating the immune system, reinforcing the plant structure and clearing excess and unused nutrients. Enhancing a garden is easy when working with the supplement options available from General Hydroponics.

SUBCULTURE® biological root innoculum
Root protection remains a key concern for all gardeners: in soil where root access is difficult, and in hydroponics where the root zone is relatively exposed. SubCulture produces enzymes (proteins that catalyse chemical reactions). It is a natural and continuous source of these biological catalysts and can replace ready made liquids with a very short life span. As long as SubCulture is alive and healthy, your plants will remain strong and protected. Protect your roots from fungi and other pathogens: Did you ever hear about “Pythium, Fusarium, Verticillium” (and all these names ending in “ium”) that create havoc and desolation in plantations and grow rooms? In all seasons, and especially in hot weather, most hydroponic growers may experience mould problems in their plants’ roots. To get rid of them, some companies will suggest UV sterilisers or liquid enzymes, with some, little, or no success at all. Of course you can use fungicides, which you will find in any garden centre. But we all know that fungicides are harmful to you and the environment. How does SubCulture work? SubCulture covers the whole root mass with a protective mycelium that impedes pathogens from feeding, growing and surviving! SubCulture has a second and equally essential function: This specific mix of bacteria decomposes the organic matter and debris in the nutritive solution and transforms this potential source of disease into a supplement of mineral salts readily available to plants. SubCulture is a natural protector. In soil and in coco fibre it will reproduce itself easily, and can simply be added into the watering solution. In hydroponics, use SubCulture with a biofiltre. When and how to use it? 10 g/150 L – every six weeks. SubCulture is used as a drench when planting seeds, in your watering solution in soil or directly in the biofiltre for hydroponics.
SubCulture is a biological root innoculum that contains a unique mix of beneficial fungi and bacteria, and whose first goal is to protect the root mass from damaging fungi like Pythium, Fusarium, Phytophtora, Verticillium, etc.
A significant drop in pH is an alarm bell that indicates the death of a large quantity of micro-organisms. In this case it is important to find the cause, treat it, and replenish with micro-organisms.
