The remains of the collapsed tower of the first experiment were inserted in a long burlap tube. Burlap is a biodegradable textile, and provides structure and nourishment to the mycelium. We rolled up the burlap tube like a big turban. We hoped the mycelium would continue to grow within the burlap and merge into one strong structure. It didn’t.
The mycelium had already lost its vitality because of our mishandling combined with very warm and sunny weather. After a few weeks the tower was removed and the mycelium composted. Perhaps burlap deserves another chance.
