Elite 91 Silicic Acid - Plant Available Bioactive Silicon
Elite 91 Silicic Acid delivers one of the most concentrated, stable liquid forms of monosilicic acid on the market - 4.1% Monosilicic Acid and 1.2% plant-available Silicon in a 100% soluble formulation. It is paired with 21 organic L-amino acids and a balanced micronutrient package of zinc, boron, molybdenum, and manganese for an extra boost to plant health, growth, and resilience.
Silicon is abundant in nature, but rarely in the bio-active monosilicic form plants can actually use. Indoor and controlled-environment grows almost always lack it. Elite 91 Silicic Acid solves that - feeding bio-available silicon straight to the root zone so plants build stronger cell walls, take up nutrients more efficiently, and shrug off heat, cold, and drought stress.

Directions for Use
Soil / Coco / Hydroponics: 0.5 ML - 1 ML per gallon. Standard: 3 ML per 5 gallons. Aggressive: 6 ML per 5 gallons.
Seedlings / Cuttings: Pre-soak medium with 0.25 ML - 0.5 ML per gallon alongside a base nutrient.
Foliar Spray: 1 ML - 2 ML per liter (standard 4 ML / gal, aggressive 8 ML / gal). Apply with lights off, once or twice a week.
Mixing: Do not premix. Add to fresh water first, mix well, then add base nutrients and additives. Adjust pH to 5.8 - 6.3.
Use with every feeding from seedling/cuttings stage through week 7 or 8 of the fruiting cycle. Compatible with any premium nutrient or fertilizer program.
