Weightplus potassium is a highly concentrated form of Potassium and Phosphorous which, when added to the nutrient solution in the bloom phase of plants, allows for luxury uptake of weight producing potassium.

Potassium is used by the plant in a great number of its processes. It is so important that the plant will take up amounts in excess of its needs. This extra potassium is used in the construction of the cell walls of the plant and so adds to the weight of the final plant.
