PowerSI Original is our cornerstone formula. PowerSI Original is used during cloning and vegetative growth. Silica in the form of silicic acid is highly bioavailable. Silicon has been shown to improve plant tolerance to abiotic stresses such as cold, heat, drought and salinity. It has also been proven to improve plant structural strength.
Always make sure PowerSI Original goes into the water first before any other fertilizers or supplements. Use at a rate of 0.5ml per gallon of water for root zone applications. For foliar feeding use at a rate of 2-4ml per gallon.
