CYCO Silica – Sturdier and More Resilient Plants!

Cyco Silica is an additive used throughout the vegetative and flowering periods of plant growth to bolster stem, leaf, and stalk thickness while also alleviating heat stress. This increased strength can lead to better support for heavy buds, reducing the risk of branches breaking under their weight.

This additive contains the cleanest potassium silicate derived silica available today. Silica, along with calcium, plays a fundamental role in building and strengthening plant cell walls. Both silica and calcium are essential elements for the structural integrity of plant cells.

  • 100% soluble source of silica
  • Primary component in formation of cell walls in plants
  • Reducing heat stress by preventing plant transpiration
  • Builds strong stems, stalks and thick leaves
  • Contains monosilicic acid, a 100% plant available
  • Aids in development of new vegetation and flowering

Silica benefits cannabis at all growth stages. Start in seedling/cloning and continue through flowering. Silica strengthens plants and roots, supports bud weight, and boosts nutrient uptake. You can apply it as a foliar spray too. Use it in hydroponics or soil setups. Follow the manufacturer’s dosage instructions to avoid overuse.
