Rhizophagus irregularis is an arbuscular mycorrhizal fungus. MegaMyco is built around this species. Species identifies the organism; it does not tell you a product’s strain, production method or performance in a particular garden. Those are separate questions.
Keep the context.
Biological compatibility, successful colonisation and a measurable plant response are different questions. The growing conditions matter, and general research is not a promise of a particular result with MegaMyco.
