Toughen plants with RAW Silica.

RAW Silica is 45% Silicon Dioxide - making it pH neutral and flowable.

As a flowable silica, 25% - 30% dissolves immediately when added to water, so is instantly available. The rest gets trapped at roots, where it benefits microorganisms

  • 45% Silicon Dioxide
  • PH neutral - does not cloud in water
  • Strengthen plants & structure
  • Suitable for grow & bloom

Silica is known to:

  • Help buffer pH (increase uptake & prevent lockout, deficiencies & toxicity)
  • Thicken stems & branches (support heavier fruit & prevent wind damage)
  • Strengthen roots  
  • Increase pest resistance (leaves develop thick outer coating that’s tough to penetrate)


How To Use

  • Dilution: 0.25g - 0.55g (Grow), 0.55g (Bloom) per 4 Litres
