Hyphae are microscopic fungal filaments. Outside the root, they extend through the surrounding medium and explore small spaces beyond the immediate root surface. Their role is not the same as adding extra plant roots. They belong to the fungal partner and operate within a living exchange relationship.
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.
