Liquid Potassium Silicate For Stronger Plants - Super Concentrate
Growing in living soil, coot originally taught us about foliar spraying with Potassium Silicate and it's become a go to for healthy plants that resist disease and have higher harvest weights. Besides that, coot taught us that potassium silicate can very effectively emulsify oils like Neem oil or essential oil for home made pesticide spray.
Liquid AgSil Potassium Silicateprovides a highly available source of silicon and potassium that helps plants build strength from the inside out. Silicon supports cell structure, improves stress tolerance, and reinforces natural defenses, while potassium plays a key role in overall growth and metabolic function. This formula is designed to be safe for a wide range of crops, including sensitive varieties, with a low salt index that fits well into professional and home growing programs.
AgSil can be applied through soil or as a foliar spray, helping plants handle drought, temperature extremes, salinity, and mineral toxicity. It also supports the plant immune response, increasing resistance to common soil and foliar pressures. Many growers prefer liquid potassium silicate for ease of use, but this powdered form offers long shelf life, flexible mixing, and excellent value once properly dissolved.
Why Growers Use AgSil Improves plant strength and structure Supports stress tolerance from heat, cold, and drought Enhances resistance to environmental and biological pressures Low salt index and safe for sensitive crops
Instructions for Use:
BuildASoil recommends using (0.5 mL - 1.5ml) of AgSil 25 per gallon of water

Excellent for emulsifying oils for foliar spray
BuildASoil has offered theAgsil16Hfor over a decade and with high demand for a liquid version and unstable supply last year of the powder, we decided to bring in the Agsil Liquid. Some growers would complain the powder bricked up or they would accidentally use to much, the liquid is heavier to ship but easy to use.
