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 increase 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.

Compatible With Your Garden

MAMMOTH SI was designed to use throughout vegetative and bloom phases of plant growth and is compatible with typical fertilizer regimes.
