Hello all Great People! I am starting this thread because I have a serious problem that it seems I cannot overtake. This problem regards my shiitake, nameko and king oyster; in short, all the types of blocks tht are fruited out of the growing bag. I fruit my blocks in a tray to avoid touching the "naked" block as much as possible. For harvesting I simply wash my hands well and take the block from the FC and up into the kitchen without touching it and cut the mushrooms with a very sharp clean blade. After harvest, I trim off any stumps that are left and reintoduce the block in the FC for subsequent flushes. This procedure is for nameko whereas for shiitake I dry the block out for a week or so after the harvest and than rehydrate it and reintroduce it to the FC. The problem is that every single time, just hen the second flush is showing, the block turns green or some other kind of mold shows on it and I end having to throw it in the compost pile. Obviously, this makes growing unviable because harvesting a single flush from a block does not make it worth. What an I doing wrong? Maybe seasoned growers like @muskie , @FallenOak or others can help me overcome this obstacle! Thanks in advance!
