If you have been searching for the perfect natural product to support any plant at any stage of growth, look no further than Liquid Fulvic Acid for Plants from Rocky Mountain BioAg®. Fulvic acids are essential for helping plants build their structures and stay healthy. This group of organic acids is water soluble at any pH level, so it doesn’t matter if the quality of your water varies slightly. This gentle yet effective solution will help your plants along without the risk of nutrient burn or other complications. 

Certain metal ions are required for cell production in plants, and fulvic acids aid in making those ions available to the plants, all while helping plants unlock other essential nutrients from the soil in which they are growing. Research suggests that fulvic acid can mimic plant hormones, stimulating cell growth, flower production, and fruit growth. 

Rocky Mountain BioAg® sources fulvic acids from some of the highest-quality ancient plant materials in the United States. Minimally processed and easy to use, this product will become your best tool in garden management. Elevate your plant health and growth with Liquid Fulvic Acid for Plants from Rocky Mountain BioAg® today.

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.
