Protecting your plants against harsh climate conditions is easy thanks to ThermX-15M Organic Yucca Meal. This powerful extract contains saponin, a natural compound found in Yucca and other desert plants that help them survive in hot, dry climates.

Saponin is a natural wetting agent that helps enhance penetration into the soil by reducing the amount of surface tension in the water. When used on soil, it also helps prevent compaction, protects against water and heat stress, increases fertilizer uptake, and aids in the permeability of clay soils suffering from alkali and salinity problems.

Adding ThermX-15M Organic Yucca Meal to your plants and trees helps improve seed germination and water and fertilizer uptake. We love mixing this conditioner into potting soil with a bit of fresh peat moss to help retain water while enjoying the nutrient benefits of peat.

If you're growing anything outside, using ThermX-15M Organic Yucca Meal is a must. Natural weather conditions can stress plants and limit quality, production, and overall plant health. This conditioner is made from 100% natural yucca and is registered for use in certified organic production with the Organic Materials Review Institute (OMRI) and the California Department of Agriculture.

    I have a greenhouse that unfortunately does not get the ideal sunlight due to its location on the north side of my home. I have been using Rocky Mountain BioAg’s Quantum Growth Organic Total for over a year and have seen a dramatic increase in plant growth and vegetable yield compared to past years. Highly recommend the product.
