Use for growing in all types of recirculating systems growing in all inert medium.If the nutrient you are using in your hydroponic cropping doesnt supply all the plants requirements, where will they get what they need? Seems an obvious question, doesnt it? Weve heard time and again people say that a nutrient is just a nutrient,-theyre all the same. Well, theyre not. We should point out, though, that in our experience this is not said by the best growers. They are much more attentive to detail than that and consequently that attention to detail is part of being a better grower.
