AMAZING!! Thank you Plant Revolution!!

For someone with a few houseplants this product is amazing in both it's use and the price. I could see visible results about 7-10 days after applying to the soil as directed on the back of the package, and after liberally knocking up about 20 different plants (in small pots) I still haven't ran through the bag! Thank you so much Plant Revolution for these products.

This Stuff Really Works!!

After doing lab experiments in University on the effects of mycorrhizal fungi inoculation on corn plants, I knew I needed to try it at home! My plant has a tree trunk sized stem and won’t stop eating! This plant got drowned in a 3 day thunderstorm then experienced upwards up 95° temperatures with straight sunlight, and it continues to be the healthiest plant I own. The Mike O’ Rizey Granular has the perfect mix of endomycorrhizal species that will help your plant thrive in nearly any condition!
