Use about 0.25 of a pound per container for expanding grain or inoculating bulk substrate. You should get about 12 expanded containers with this per spawn bag. I maintain a number of first generation spawns and the 7 - 10 days is the amount of time it takes to colonize new blocks with the first generation make it second generation. 3 pound blocks, 4 blocks in package, 12 pounds total. 5in x 4in x 18in unicorn gusseted bag.
Bags are prepared in front of a flow hood. Sterile techniques should be practiced when working with mushroom substrates. Take care to have clean hands and a clean environment.
70% isopropyl alcohol is great for spraying with work area and spawn containers. If possible perform all work in front of a flow hood.This item is made of blue oyster mycelium and rye grain, milo grain.
