    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!

    Soaking in lime watee could help. Twisting fruit instead of cutting. Any stumps are susceptable to infection. More FAE. Your doing nothing wrong it could be the area you live too, high humidity is great for all fungus. Just prolific is all.

    Sounds like an air movement situation to me.

    You may not be able to do much about the air movement but a water hose or water with a little pressure will clean the mold off a block really well. A lot of folks use that trick.

    King oysters have given me trouble with mold on the casing layer as well. Sometimes they green after the first flush, other times I get 3-4 flushes before they green. I've found a higher lime content in the casing layer helps fend off the mold. As Muskie said, spraying blocks of with a hose can also really help, shiitake blocks tend to be pretty mold resistant IME, but then again I did find a small amount of mold on a few in my last batch at around the third flush.l, I simply sprayed them off well with the hose before soaking them.

    What are your supplementation rates like? Too high and it invites mold early on, too low (for oysters especially I find) and the blocks aren't as vigorous and tend to have higher occurances of mold later on.

    These are a couple of nice tricks, thanks! I will surely try them quite soon as I have a mess at the moment.

    Supplementation is 5% for shiitake so it should not be too high.
