MontanaGrow is 76% amorphous silicon proven to increase: Plant Cell Wall Strength Photosynthesis Disease Resistance Flood Tolerance Nutrient Balance UV Tolerance Carbon Sequestration Drought and Salt Tolerance High & Low Temperature Tolerance Blocking of Heavy Metal Uptake Alleviate Biotic Stress MontanaGrow silicon strengthens plant cells from roots to shoots, helping to repel insects. Alleviate Abiotic Stress Plants survive and thrive through frost and heat events allowing for a longer growing season. Great Organic Input Option Food grown with MontanaGrow can be certified organic, is healthier, and more nutrient dense. MontanaGrow Volcanic Tuff Additional Benefits Revitalize Soil and Improve Plant Health Moderate pH Acts as a Buffer High Cation Exchange Capacity Increased Ability to Hold Moisture 3.5 on the MOHS Hardness Scale Chemical Free Will Not Burn Plants Does Not Run-off or Leach Reduces Nitrogen Volatility Improves Phosphorus Availability Unique Source of Silicon Result of Ancient Pyroclastic Flow Mined from a rare deposit of silicon rich, non-crystalline volcanic tuff formed over 30 million years ago by a pyroclastic flow. Has a rich amorphous content that contains over 76% SiO2 providing a natural source of plant available silicon (silicic acid). Porosity Unlike Any Other Silicon Source Extremely porous, weathers easily, and provides immediate and gradual release of plant available silicon. Reacts dynamically with other minerals and nutrients to address critical soil and plant deficiencies. Amorphous, non-crystalline silicon and is not a hazardous or harmful material.
