Mammoth Si is uniquely formulated
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.

MAMMOTH Si Registration Map
Is Mammoth Si a liquid or dry product?
Mammoth Si is a liquid product.
What is the shelf life? When does it expire after opening?
Mammoth Si shelf life is 2 years.
How do I store Mammoth Si?
Always store Mammoth Si in its original packaging. Store locked up in a dry and well-ventilated area.
How do I measure the product?
Measure small amounts of Mammoth Si with a pipette, syringe, or small measuring cup. If measuring larger amounts, use a larger measuring cup or graduated cylinder.
What is the application rate and frequency for applying Mammoth Si?
Apply 0.5 mL/Gallon, every 5-7 days (always adjust pH accordingly after mixing into reservoir).
Can I use on my seedlings/clones?
We recommend starting applications at the vegetative growth stage.
Do I add to nutrient mix? If so, when? Is the order of mixing important?
Yes and the order of mixing is important: add Mammoth Silica first, then any nutrients and pesticide products, adjust pH if necessary, and add any beneficial products (i.e. Mammoth P) as a final step.
Do I need to pH my water with the silica product?
Yes, always adjust pH after adding Mammoth Si.
How frequently should I apply Mammoth Si?
Apply Mammoth Si every 5-7 days.
What are the main benefits of running Mammoth Silica?
Plant strength and stature.
Do I use in flower and flush?
We specifically formulated this product with low nitrogen so growers can use it in the flowering stage of growth, reducing a need for two products or differing application rates.
Are there any products I shouldn’t run this with?
Is this organic/OMRI-certified?
I already use a silica product, how is this different?
Low usage (application) rate, lower nitrogen for use from vegetative through bloom growth phases – only one product is needed for any growth stage, Mammoth Si has a high mono-silicic acid percentage with 1.9%.
Can I get a sample of this new silica product?
Please visit your local retailer in states with approved registration.
Why is the monosilicic-acid (MSA) percentage not displayed on the Mammoth Silica product label?
We see many silica product labels that do not list mono-silicic acid percentage claims due to the high variability of how labs can analyze and present these claims. Mammoth uses the testing methods that California & AAPFCO use for measuring soluble silicon.
What is the difference between potassium silicate and mono-silicic acid?
Potassium silicate is a silica source (very alkaline on pH scale) and it must be converted into mono-silicic acid before it’s available for plant uptake. Mono-silicic acid is the plant-available form of silica and it’s derived from a silica source.
