Arbuscules and diagnostic root structures are microscopic. Specialists often stain roots and examine them under a microscope to assess colonization. White threads on a pot’s surface can belong to many organisms and do not prove MegaMyco has established. Healthy-looking roots alone are also not a confirmation.
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.
