Pro Powders Silica Pro™ Potassium Silicate

Silica Pro™ is a high-purity potassium silicate powder formulated to supplement crops with soluble potassium (K₂O) and plant-available silicon (Si). Silicon strengthens cell walls, supports upright growth, and improves tolerance to environmental stress including heat, drought, salinity, and fungal pressure.

Key Features

  • High-purity potassium silicate — fully water-soluble powder
  • Delivers both plant-available silicon (Si) and potassium (K₂O)
  • Strengthens cell walls — improves resistance to fungal pathogens and insects
  • Enhances tolerance to heat, drought, and salinity stress
  • Suitable for hydroponics, soilless media, and traditional soil cultivation
  • Raises solution pH — add to water before other nutrients

Ideal Applications

  • Hydroponic nutrient solutions
  • Fertigation: drip, micro-jet, sprinklers
  • Foliar spray programs
  • High-stress crop environments

Packaging Options

  • 1 lb
  • 3 lb
  • 20 lb
  • 50 lb

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.
