Brutal Silica is the ultimate structural reinforcement for your crop, formulated with monosilicic acid (orthosilicic) to guarantee immediate absorption by your plants. Unlike traditional silicon, this additive does not need to break down over time; it acts instantly to create steel-like stems capable of supporting the heaviest buds without snapping, while improving resistance to pests and environmental stress.
There is nothing more frustrating for a grower than seeing how, with the same seeds and the same setup, results vary wildly from one crop to another. Sometimes the branches hold up well, other times they bend under the weight or succumb to a heat wave that ruins the harvest. That feeling of "gambling" with your time and money generates unnecessary anxiety.
This inconsistency takes away your confidence. You spend months pampering your plants, only to find that a fungal attack or a peak in temperature throws all your work overboard because the plants were structurally weak. Trying to guess if this time they will survive the fattening phase without stakes or supports is a headache you don't need.
The solution is to armor them from the inside. Brutal Silica eliminates that variability factor. By providing bioavailable silicon, you ensure that every plant develops a robust cell wall, regardless of external conditions. It is the tool that transforms a "delicate" crop into a stable, repeatable, and resistant machine, allowing you to focus on fattening rather than fixing problems.
The secret to the stability this product offers lies in its formula: orthosilicic acid (4.21%). Most silicon supplements on the market are potassium silicates that the plant takes weeks to transform and assimilate. Brutal Silica is already in the chemical form that the plant "eats." This means that from the first watering, you are actively reinforcing the structure.
In addition, its composition includes Iron, Molybdenum, and Zinc, creating a synergy that stabilizes the plant's metabolism. By using it, you standardize the internal health of the crop. It doesn't matter if it's a bit hotter than usual or if there is a pest prowling around; the structural integrity of the plant remains constant, giving you predictable and professional results cycle after cycle.
Yes, it is compatible with almost all ranges, but you must always add it to the water first, mix, and then add the rest of the nutrients. This prevents it from blocking other minerals.
For constant structural maintenance, use it in irrigation. If you have a specific stress problem (heat or pest attack), a foliar application is faster and more effective in the short term.
Yes, silicon products generally raise the pH. Always measure and adjust the pH at the end of preparing your nutrient solution to ensure it is in the optimal range.
I've spent years testing additives, and if there's one thing I've learned, it's that silicon is not "optional" if you want serious results. Before using monosilicic acid like Brutal Silica, I had crops where the tips burned from heat or branches bent, forcing me to tie everything up like a spider web. It was chaotic and inconsistent.
Since I incorporated Brutal Silica into my base routine, the difference is night and day. The trunks look like tree bark, hard and resistant. I've noticed that the plants tolerate fertilizer peaks much better and don't get stressed if the temperature rises a couple of degrees. For me, it's the insurance that allows me to sleep peacefully knowing that the crop will reach the harvest intact and with maximum weight.

Since I started using Brutal Silica, my plants have completely changed. The flowers are denser and the plants are more resistant to any pest attack.
