Description
Reinforce cell walls for tougher, more resilient plants
SHOGUN Silicon is a concentrated, highly refined potassium silicate additive that fortifies plants against pests, disease and environmental stress by strengthening the plant's own structure from the cell wall outwards. Mixed correctly it forms stable silicic acid in solution for maximum uptake, giving the basis for strong, healthy development and better stress resistance.
Weak stems and poor stress tolerance?
Thin, under-built cell walls leave plants floppy, prone to pest and disease attack and quick to wilt under heat or light stress. SHOGUN Silicon reinforces plant tissue at a cellular level, thickening cell walls so stems stand up under their own weight and foliage shrugs off environmental pressure.
Key Benefits
- Concentrated, highly refined potassium silicate designed for maximum uptake
- Forms stable silicic acid in the nutrient solution when mixed to instruction
- Buffers pH fluctuation in the reservoir for a more stable feed
- Increases resistance to disease and pest invasion
- Strengthens cell walls for sturdier stems and stronger overall structure
How to Use
- Root feed: add plain water to your reservoir or watering can, then add SHOGUN Silicon at 1ml per litre
- Add it first: reduce pH to just below 7, then add your other additives and base nutrients
- Every tank: repeat the method at each tank change or refill
- Whole crop: use throughout the life of the plant, vegetative through flower
