What else do you plan on using? I don't know this product but seems to be really strong. I would look else where. Maybe someone had used it that can give you info on it.
Probably quite strong as it is a powder, and not a liquid specifically designed for hydro. i just thought it could be cut down to 25% or something. it dissolves perfectly, leaving no sediment at all. and has every nutrient a plant could need. but of course there are many other formulations that could be used additionally.
If one had to choose a single formulation to be used throughout a whole growth cycle in DWC what would you pick?
