Grotek Pro Silicate

Quick Answer

Grotek Pro Silicate is a concentrated 0-0-4 potassium silicate additive for hydroponic and soilless growing. Use during vegetative and flowering growth at 2.5–5 mL per 4 L of water. Add it to water before concentrated nutrients, agitate well, then check and adjust the solution to pH 5.5–6.5.

Product Description

Pro Silicate supplies soluble potash and silica to support plant cell-wall strength and overall structural integrity. Grotek recommends it for hydroponic systems and soilless media, including peat and coco, through both vegetative and flowering stages. Adequate silica can help plants tolerate abiotic stress such as heat and drought; results vary with crop, environment and the rest of the nutrient program.

Package Contents

1 × Grotek Pro Silicate container in the selected 1 L, 4 L or 10 L size.

Directions for Use

1. Fill the reservoir or mixing tank with water.
2. Add 2.5–5 mL of Pro Silicate per 4 L of water.
3. Agitate the solution thoroughly.
4. Check and adjust the solution to pH 5.5–6.5.

If Pro Silicate must be added after nutrients, pre-dilute it and add it slowly while agitating. Rapid pH changes can cause nutrient precipitation.

• Keep the container tightly closed in a cool, dry, well-ventilated place.
• Keep out of reach of children.
• Clean spills promptly and dispose of product and packaging in accordance with local requirements.
