Veg – bloom. One product.

MAMMOTH® SI was uniquely formulated to provide you a single formula and application rate to use throughout your entire growth cycle. Our unique formulation allows for increased bioavailability of silicic acid to maximize plant silicon uptake.

More Concentration. One low use rate.

With our unique formulation, growers can use one low use rate (0.5 mL/ GAL) from early growth all the way through bloom.


Grow Mammoth Strong

Structure = function

Silica helps plants improve cellular development and shows to help increase the production of cell walls. Think of silica being the mortar that holds bricks or, in this case, cells together, creating a more sturdy framework for the plant. This framework allows cell walls to work more efficiently and be more effective at their job.

Strength & Stature

Silica is known for increasing the strength of cell walls in plants. If your goal is to produce dense flowers and increased yield, you can grow the biggest flowers, but your plant stems need to support them to develop fully.

If you’re an outdoor grower, heavy winds and storms can all too easily take a toll on your plants.

Silica enables plants to grow thicker stems allowing the nutrients to move more easily through the plant to the areas that they are needed most.
