GT Silica – Strengthen Plant Cell Walls for Healthier Growth
GT Silica is a concentrated potassium silicate additive designed to supply plants with bioavailable silica – a mineral not naturally present in most hydroponic solutions. Regular use helps fortify plant cell walls, making them more resilient against pests, diseases, environmental stress, and physical damage.
Why Use GT Silica?
- Strengthens cell walls for improved structural integrity.
- Boosts resistance to fungal infections, insect attacks, and environmental stress.
- Increases chlorophyll production for more efficient photosynthesis and CO2 uptake.
- Helps maintain leaf variegation and reduces the risk of brown spotting.
- Suitable for all growth stages – vegetative through to maturity.
Directions for Use
Hydroponics / Semi-Hydro: Add 5ml per litre of plain water, stir thoroughly, and let sit for 15 minutes before adding nutrients. Adjust pH to 5.5–6.5 after mixing.
Soil / Potting Mix: Add 2–3ml per litre of plain water, stir thoroughly, and let sit for 15 minutes before watering plants.
Tip: Always mix GT Silica into water before adding other nutrients to avoid precipitation and ensure even distribution. Handle with care – wear gloves and eye protection when using the concentrate.
