Description

Silica in the cell wall, laid down while the tissue forms

Rhino Skin is a potassium silicate supplement that strengthens cell walls. Silica is deposited as tissue forms, so it has to be supplied during vegetative growth and the stretch - adding it in late flower achieves very little.

Key Benefits

  • Stiffer stems - branches that hold a heavy canopy without staking
  • Tougher leaf surface - harder for sap-feeding pests and mildew to penetrate
  • Better heat tolerance - silicified tissue loses water more slowly
  • Timing matters - supplied while tissue is forming, not afterwards
  • Any base feed - mineral or organic

Branches bending under the weight they set

Growth pushed hard under strong light gets tall before it gets strong, and by mid-flower the branches are bending under weight they should be able to carry. Once tissue has formed, silica cannot be retrofitted into it - the window is earlier than most growers use it.

How to Use

  • Vegetative growth: 2 ml per litre at every feed
  • Through the stretch: 2 ml per litre for the first three weeks of flower
  • Mixing: ⚑ add to plain water first and stir before anything else - silicates raise pH sharply and will precipitate with a concentrated feed
  • pH: check and correct after mixing, not before
  • Late flower: taper off - structure is already set

  • Role: Cell wall strengthener
  • Typical dose: 2 ml per litre
