determines whether you will get the same average yield as most or that huge, prized, monster harvest. After a while of feeding your plants, salts inevitably start to build up, and you can see this if you wash your medium through with a weak nutrient solution. Measure the EC levels of this run-through. The likelihood is that it will
come out at 3.6+, even if your plants are being fed with an EC of just 1.4! To put it simply, this does not mean that your plants are getting too much of what they want, they may simply be taking up exactly what they need and leaving the rest behind. This starts to build up and eventually locks out other nutrient uptake, though the plants www.thegrindmagazine.co.uk

This build-up has to be avoided in the first place. The Super Charge method ensures the medium contains exactly what the plant wants 57
