HYBRID FACILITIES

A Hybrid greenhouse utilizes the design concept of a Positive Pressure Greenhouse but adds one additional and very useful item, air conditioning.

Hybrid greenhouses can utilize dehumidifiers, chillers, coolers, or traditional HVAC. This allows the grower to use the greenhouse as a traditional greenhouse most months of the year, utilizing outside air. During those months when the air is too hot, or more likely, too humid, the outside vents close and instead of pulling outside air into the greenhouse, chillers or air conditioners scrub the air free of humidity, mold, pollen, spores and of course lower the temperature. This cold air is then pumped into the cooling chamber where it is pulled into the greenhouse and distributed through the ducts under the crop's root structure and is forced through the canopy. During this period, the greenhouse remains closed, and the air is returned back to the cooling chamber to be scrubbed of humidity, and heat and then pumped back into the greenhouse. While this offers incredible control and the most ideal environment, the utility expense during this period can be 10 times or more expensive than the traditional positive pressure method of cooling a greenhouse through evaporation of outside ambient air temperature. Many growers will argue that this is the best option available today giving them the ability to utilize many different environmental control options as the seasons change to make their operation as efficient as possible.

6

Totally Enclosed Greenhouse Facilities The most controlled environmental option available on the greenhouse market at this time. A totally enclosed greenhouse utilizes the design of positive pressure along with traditional HVAC heating and cooling to consistently set the temperature and humidity to the exact set points desired and the ability to achieve those set points year-round regardless of outside temps or humidity. The capital expense of this option, as well as the ongoing energy use make this the highest price option; however, it is the most accurate control. In this option, growers have the result of an indoor growing facility with complete control of temperature and humidity, but one key factor that makes this option attractive in today’s cannabis market – Natural sunlight! Sunlight plays a major role in determining the success of year-round cultivation of high-quality flower in other greenhouse ventilation and cooling options previously discussed. As the sunlight rises above the horizon it immediately begins creating a solar buildup in the greenhouse.

The thermal load from the sun, especially when humidity levels are very high, is less than ideal for cannabis in flower making it at times almost impossible to maintain acceptable plant health during this period and can lead to crop failure and loss. DLI (Day Light Integral) is a measure of the total light accumulated in a 24-hour period. When growing in a greenhouse, growers can reach a DLI of 40 moles per day per meter squared, which is an ideal light accumulation and is unobtainable in an indoor growing environment with only grow lights. There truly is no substitute for the sun when growing plants, but a totally enclosed greenhouse provides growers with a clean, exact condition while still letting the sun in.

► Fan & Pad Negative Pressure Cooling The most traditional design on the market and by far the lowest cost method to cool your greenhouse.

Negative Pressure cooling uses exhaust fans at one end of the greenhouse to pull or exchange the air in the greenhouse out of the building with fresh outside ambient air temperature at least once per minute. The temperature can be lowered through evaporation of a simple pad system or cool cell. As the air is chilled through evaporation, it is pulled to the opposite end of the greenhouse and forced out of the building through the exhaust fans. This cycle happens over and over again up to 1.3 times per minute. While this is the most inexpensive capital expense as well as most economical operational expense, this is the least effective method for hot humid climates to produce cannabis. In fact, without switching completely to an extraction only operation during hot humid months in certain parts of the country, this method of growing may be unusable.

► Natural Ventilation with sidewalls and roof vents Natural ventilation operates on the principle that heat is removed from the greenhouse by wind and temperature differences between the inside and outside of the greenhouse. Wind is what we primarily depend on. Even light winds as low as 1-2 mph are sufficient to keep the inside temperature of the greenhouse within a few degrees of the outdoor temperature. When ridge vents are used, the hot air inside the greenhouse will rise and escape through the roof opening. The greater the difference in temperature between the inside and the outside of the greenhouse, the greater the results.

What are the advantages of Natural Ventilation?

There are a lot of crops that do well in greenhouses with natural ventilation. The lower initial cost sidewall rollup curtains versus the high electrical cost of operating exhaust fans makes natural ventilation an attractive option. Greenhouse sidewall vents provide a low cost, low maintenance solution.

Light Cycle Control Retractable Light Deprivation Curtains Retractable light deprivation curtains are commonly used in commercial greenhouses to control day length. As a result, growth and fiowering of photoperiodic plants may be controlled. Plants detect light from any holes or gaps. Proper blackout systems are typically combined with light traps, covering the exhaust fans and cooling systems to create an area completely void of light. A high-quality light deprivation system is a crucial component to successful cultivation.

Breathable Light Traps Light traps are used to cover exhaust fans, evaporative cooling systems, and air intake shutters. Their unique design allows air to flow freely while blocking all light from entering the greenhouse. In mechanically ventilated greenhouses, light traps are necessary to control day length and keep your growing and cultivation on schedule. Our cannabis cultivation structures are designed with light traps and the required housings to cleanly and effectively block light without obstructing the air flow.

HPS & LED Lighting HPS lights emit light in the red spectrum (600-700nm approx.). This stimulates top growth, creates longer internodes, and encourages flowering.

Light emitting diode (LED) lamps are becoming more affordable with higher output. LEDs are offered with full spectrum lighting that ranges from blue to red.

LEDs also run cooler than HPS and MH lights, generating less greenhouse heat build-up which allows light fixtures to be positioned closer to the plants.

Insect Exclusion

Pest management and exclusion is an important strategy to implement into your greenhouse planning. We offer several methods that integrate these goals into each greenhouse project.

Insect Screen

Insect screens are designed by mesh size based on the target pest to be excluded.

Tight mesh designed to target thrips and other small insects can greatly reduce air flow and cause the greenhouse to overheat. To prevent the greenhouse from overheating, screens and cooling equipment must be properly sized to function correctly. Our team of professionals will design your greenhouse for the best results.

Double-Entry Rooms

Double-entry rooms are designed to create an extra layer of defense by serving as a pre-entry room before personnel enter into the greenhouse. These rooms are the most effective when designed with positive pressure air flow blowing against the outside door opening. Fans or air curtains can be used to create the positive pressure for double-entry rooms.

Insect Exclusion Facility Designs:

Fertigation Systems Dosing water and nutrients is one of the most crucial processes in any horticultural operation. Irrigation and fertilization (or 'fertigation' for short) are crucial to the productivity and quality of your crop, and therefore the viability of your business. So reliable and efficient fertigation is a critical process for every grower. An automated dosing system, such as the Ridder FertiMiX units, can provide the perfect solution. The Ridder FertiMiX enables you to manage irrigation and fertilization easily, efficiently and accurately, so that you can achieve optimum crop quality and growth and healthy returns. The mixing tank fillers and fertigation units are suitable for all types of substrates as well as hydroponic cultivation, and they can be tailored to a range of different settings and scales. This means that every grower can find the perfect settings, saving them money on irrigation and fertilizer costs. And that's essential because every drop counts.

EBB & FLOW BENCH SYSTEMS

An ebb & flow bench includes plastic "ebb-flow" trays that rest on top of the bench.

The original purpose of an ebb flow bench was for irrigating purposes. Water would flow through the tray and irrigate the plants. That is still a purpose, but another purpose is to sim ply catch water from other forms of irrigation and drain it off rather than going on the floor.

Our Ebb and Flow rolling benches are designed with the grower in mind. With available width options of 4', 4.5', 5', 5.5' and 6', we can maximize the efficiency of your growing space. Benches are designed to accommodate our molded polystyrene Ebb and Flow trays. Welded bench frames are built from 1" square galvanized steel tubing. Cross support ribs are spaced every 18" to support even the heaviest crops. Threaded height adjustment allows approximately 4" of leveling. Extruded aluminum side-rails are designed to accept optional trellis support arm s. Trellis arms are a great option for providing additional canopy support for your crop.

We manufacture additional bench designs that include expanded metal and wire mesh bench decking. On expanded metal or wire benches, plants simply sit on the bench and any water or soil would fall through to the ground. We offer rolling, palletized and stationary benches in both expanded metal and ebb & flow.

16

What are the costs associated with Ebb & Flow Benches?

Cost depends on size and additional items that may be ordered with the benches.

For example, a customer can order gutters at the end of benches to collect the water and drain off. Average pricing per sq. ft would be around $8-10 per sq. ft.

How are Ebb & Flow benches relevant and/or advantageous to the cannabis industry?

There are generally more regulations in the cannabis world that relate to molds, etc. Ebb & Flow benches keep the water contained, the facility cleaner, and spread of plant diseases and contamination to a minimum. Additionally, trellis posts may be added to the bench for bench crop containment.

What types of Ebb & Flow bench systems, components and services does Atlas offer?

Atlas offers any type of ebb flow OR expanded metal benching, both rolling, stationary or palletized. Atlas also offers installation services.
