Brutal Silica - Orthosilicic Acid

Brutal Silica is the ultimate silicon booster, delivering fast, stable, and highly efficient absorption of orthosilicic acid, the most bioavailable form of silicon. This premium additive reinforces plant structure, enhances flowering, optimizes nutrient uptake, and increases resistance to pests and environmental stress.

Perfect for all growing mediums, Brutal Silica is an essential supplement for hydroponic, coco, and soil-less systems, where silicon is not naturally present.


What's the result of using Brutal Silica?

✔️ Extreme structural reinforcement Silicon strengthens cell walls, making stems thicker, harder, and more resistant, preventing bending under heavy flower weight.

✔️ Brutal flower density — Stronger cellular structures reduce post-harvest moisture loss, leading to rock-hard, weight-packed buds.

✔️ Natural pest and disease shield Thicker leaves block insect attacks and fungal infections like powdery mildew and botrytis.

✔️ Greater tolerance to environmental stree — Brutal Silica enhances resistance to heat, drought, and excessive light, especially in LED setups where silicon demand is higher.

✔️ Maximized nutrient efficiency — Regulates ionic balance within the plant, increasing bioavailability of Fe, Mo, and Zn.
