MontanaGrow™ is a naturally produced and unaltered plant amendment that builds strong roots, stems and foliage. It improves yield and quality of many plant species by building more biomass through increased nutrient uptake. This plant available silicon helps enhance the production of chlorophyll which in turn increases the number of CO2 receptors in plant tissue. MontanaGrow™ is an adjuvant utilized for its ability to enhance nitrogen reducing its volatility, and for unlocking phosphorous in soils.

MontanaGrow™ is highly absorbent helping soils to retain moisture more efficiently which allows for less frequent watering.
