Mycorrhizal Fungi OMRI Organic Root Enhancer for Plant Success, Super Potent 20 Strain ECTO and ENDO Blend for Trees, Vegetables and Houseplants, Beneficial Bacteria Included Treats 3,000 Plants

I bought this to replace Bigfoot Mycos for a hydroponic setup. Unfortunately I quickly found out this product was not suited to that grow form. There's so many beneficial bacteria and fungi in this that it quickly caused my pH to run acidic. A bacteria in this ran rampant and my pH would drop by almost 2 points a day. Other than hydroponics this product does very well in soil. I do not recommend this for any hydroponic setup. I would really like to see a hydro safe product from this company to compete with the rest of the overpriced myco/beneficial bacteria market.
