Growth Technology Silica

From the clever guys and gals at Growth Technology comes GT Silica, known as "Nature's Bodyguard"

Why give your plants Silica?

Silica is a natural powerhouse nutrient abundant outdoors but missing indoors. Adding Silica to your feeding routine gives indoor plants the protection that nature would normally provide, making plants stronger and hardier, both physically and by supporting stronger defences against pests, diseases and environmental stresses. It's like a bodyguard for your plants!

Which plants need GT Silica?

All plants benefit from Silica but not all plants need it. Outdoors if you test your soil you may find silica in abundance due to soil water, however indoors silica is not naturally available. Silica can be used as a pro-active protectant for any plant not already getting silica naturally, or where soil water is deficient.

Silica can also be used defensively for plants under stress or attack, however is best used proactively 'little and often' as silica is not a mobile nutrient, meaning plants can't correct a deficiency by shifting silica within itself. Plants rely on their substrate to meet their silica needs.

Silica also strengthens sensitive or weaker plants prone to stem weakness, browning and wilting, and helps plant's prone to attack by pests, fungus such as

What's in GT Silica?

A concentrated blend of silicic acid and potassium hydroxide (called potassium silicate). Considered the superior form of silica for plants. 

Silica for environmental stress

Plants deposit silica in their cell walls, strengthening roots, stems and leaves, acting as a protective barrier between the plant and the environment. Silica increases physical strength for plants prone to weak stems, browning, drooping or wilting leaves. The protective barrier also helps plants handle water and temperature stress. Reducing the impact of under- and over-watering as well as extreme hot or cold temperatures.

Silica for pests

Silica is part of nature’s defence system against pests that feed on roots, stems and leaves, such as fungus gnat larvae, mealybugs and root mealies, aphids, thrips and spider mites.

Silica for browning in variegated leaves

Silica is recommended by some experts to prevent the white variegated portion of the plant's leaves turning brown.

How much?

Mix up to 5ml GT Silica to 1 litre water (to maintain 20ppm silica). 

How often?

Silica is not a mobile nutrient. Plants rely on a regular supply. For best results, add GT Silica every time you water or every week.
