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.

Does the job
Tastes like boiled oysters, so it has that nailed down. I use it in my shrimp ramen noodles sometimes, sometimes I use it to flavor garnish dishes. Best price I could find, but apparently it is a specialty product.

Unparalleled source of heme iron.
This stuff is medicine if your are anemic or have low serum iron. Elemental iron from veggies or pills must be prepared by your body to carry oxygen in hemoglobin. Not so with iron from animals and oysters are unparalleled in iron content. Even if you don't find them delicious you will find them efficacious.

Do not recommend
Edible, though barely. Definitely the worst tasting oysters I've tried of all the brands. Hopefully I don't get food poisoning as has been reported by other reviewers.

High quality product.
Warmth? I’m not sure what that means. I make a simple dish out of these, some milk, butter and salt and pepper—then I “warm” it up. They’re a little pricey but the quality and taste/flavor is great. I would definitely buy them again.
