I've noticed that keeping my FC in the dark with a blanket over it produces faster growth of mushrooms. In comparison, when I give them light for half the day the growth slows. Why is this? The only time I don't have them in the dark is for the brief moment of fanning the FC. Once I've done that I put the blanket back over it, shut the closet and leave it be. What effect does the light have that benefits growth? I certainly don't see any benefit. Seems like it takes them longer to grow with light. Has anyone else tried this?
