Using this patented method, our microbes form a unique synergistic community that is more effective together, as a system, than singularly-grown microorganisms.

Just stated using it

I can't give a review so early, I just started using it on some vegetable starts, and my house plants. It's been cold and raining a lot here in No. California. Give it some time, I'll let you know. But I can report that my friend who recommended your products , has the most amazingly healthful happy house plants that I have ever seen ! they are practically vibrating with wholesome aliveness. That's why I bought it.
