SILICA · Silica additive
Build a tougher plant.
Silica isn’t fertiliser — it’s armour. SILICA is a potassium-silicate additive that strengthens cell walls, so plants stand up straighter and shrug off heat, pests and disease.

Why it matters
A stronger plant copes better.
Silica lays into the cell walls the plant builds, making stems, leaves and roots physically tougher — and a tougher plant handles stress with less lost growth.
Stronger cell walls
Silica reinforces the plant’s own structure.
Stress tolerance
Better through heat, drought and hard light.
Pest & disease defence
A tougher surface is harder to attack.
How SILICA works
Armour, from the inside.
A potassium-silicate additive that reinforces the plant’s own structure.
Potassium silicate Cell-wall builder
Silica deposits into cell walls, stiffening the whole plant.
Stress tolerance Resilience
Stronger tissue copes better with heat, drought and light.
Physical defence Pest & disease
A harder surface resists insects and fungal attack.
Add it first Mixing order
Always add to water before other nutrients to avoid lock-out.
Why growers run it
Skip it vs. run it.
