GT Silica by Growth Technology is a concentrated potassium silicate solution designed to strengthen plant cell walls, improve structural integrity, and enhance resilience against environmental stressors. By delivering soluble silica in a highly bioavailable form, it reinforces stems and leaves, allowing plants to better support heavy fruit and flower loads while resisting breakage and wilting.
Silica is a vital yet often overlooked element that boosts plant defences against pests, diseases, and abiotic stress such as heat and drought. GT Silica works by integrating silica into plant cell walls, creating a physical barrier that deters fungal penetration and insect damage. This fortified structure also improves water retention, reducing moisture loss during dry conditions.
Suitable for hydroponics, coco coir, and soil-based systems, GT Silica can be added to your nutrient program or used as part of a foliar spray for direct uptake. When used consistently, it promotes thicker stems, more robust leaves, and an overall sturdier plant structure, helping crops achieve maximum yield and quality.
Give your plants armour from within, silicon strengthens, protects, and boosts performance.
