The gold standard of microbial root inoculants!

The most powerful Mycorrhizae is here!  Big Foot Gold is the pinnacle of the next generation of mycorrhizae that will supercharge your growth.  It was engineered ingredient by ingredient to maximize every aspect of the natural symbiosis between mycorrhizae and roots. Unlike competing brands, Big Foot Gold uses carriers that aid in stimulating mycorrhizal growth, which means less waste and better results, faster.

Big Foot Gold is a direct-to-root inoculum that sets a new standard of what an elite product should look like. With 400 in-vitro endomycorrhizal propagules per gram and almost 1 billion colony-forming units per gram of nitrogen-fixing beneficial bacteria, Big Foot Gold is second to none.  Big Foot Gold can be applied directly inside the potting hole or mixed with water to make a solution.


Glomus aggregatum - 100 propagules/gram
Glomus etunicatum - 100 prop/gram
Glomus intraradices - 100 prop/gram
Glomus mosseae - 100 prop/gram

Bacillus subtilis - 350,000,000 cfu/gram
