Pro Powders Silica Potassium Silicate, 50 lbs

Silica Pro™ is a high-purity potassium silicate powder formulated to supplement crops with soluble potassium (K2O) and plant-available silicon (Si). These elements may support enhanced structural integrity, upright growth, and tolerance to environmental stress. Suitable for use in hydroponics, soilless media, and traditional soil cultivation.

Application

FOLIAR - Apply directly to the leaves using a sprayer. This method allows for rapid nutrient absorption through the leaf surface, providing quick corrective action for deficiencies and boosting plant vitality during key growth stages.

FERTIGATION - Delivered through an irrigation system, fertigation feeds plants while you water. This method ensures even distribution of nutrients directly to the root zone, making it efficient for larger gardens or automated systems.

SOIL DRENCH - Pour the diluted solution around the base of the plant to soak into the root zone. This deep-feeding method nourishes roots directly and is ideal for systemic nutrient uptake and long-term plant health.

TOP WATERING - Apply the solution manually over the soil surface with a watering can or hose. As water moves downward, nutrients are carried through the root zone, making this an easy, effective feeding method for container or in-ground plants.
