The relationship can establish in suitable soilless environments because the host is the living root, not soil alone. Substrate properties, irrigation, oxygen and nutrient supply influence establishment. Apply this granular material near roots rather than through irrigation lines. Coco use still requires appropriate nutrition and root-zone management.
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.
