Cannabis sativa can form arbuscular mycorrhizal associations. Published research has examined cannabis seedlings inoculated with Rhizophagus irregularis. That establishes biological relevance; it does not establish a MegaMyco-specific yield or quality claim. Place granular inoculum close to roots at transplanting, and maintain appropriate growing conditions.
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.
