Description
Silicon laid into the cell wall while the tissue is forming
Hesi Silicio is a silicon supplement that strengthens cell walls. Silicon is deposited as tissue forms, so it has to be supplied through vegetative growth and the stretch - adding it in late flower achieves very little.
Key Benefits
- Stiffer stems - branches that carry a heavy canopy without staking
- Tougher leaf surface - harder for sap-feeding pests and mildew to get into
- Better heat tolerance - silicified tissue loses water more slowly
- Timing is the point - supplied while tissue forms, 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. Silicon cannot be retrofitted into tissue that has already formed, so the useful window is earlier than most growers use it.
How to Use
- Vegetative growth: 1 ml per litre at every watering
- Through the stretch: continue for the first three weeks of flower
- Mixing: ⛑ add to plain water first and stir - silicon raises pH and will precipitate with a concentrated feed
- pH: check and correct after mixing, not before
- Late flower: taper off - structure is already set
