MAMMOTH® SI is a plant additive that has been specially formulated to simplify your growth cycle. With just one formula and application rate, you can use MAMMOTH® SI throughout your entire growth cycle.

Our unique formulation allows for increased bioavailability of silicic acid, maximizing plant silicon uptake. Silica is essential for cellular development and can help increase the production of cell walls, creating a more sturdy framework for your plants. Think of it as the mortar that holds bricks, or in this case, cells, together. A more robust framework enables cell walls to work more efficiently, making them more effective at their job.

With MAMMOTH® SI, you can achieve these benefits without the need for multiple applications or high use rates. Our unique formulation allows growers to use a single low-use rate of just 0.13 mL/L from early growth all the way through bloom.

Experience the benefits of MAMMOTH® SI and simplify your growth cycle with confidence.
