    Hey everyone,

    I got to a situation, where I need some help. I prepared 4 samples, to learn how to grow. I set them up first week in september. Unfortunately 3 bags stoped growing, it could be by bad gasses circulation, according to person with lot of experince. I tried to cut more holes and it seems to help.

    Fourth bag is fully grown mycelium, I cut holes to let grow mushrooms out but it only grow white mass inside of bags, in some places it is turning licht brown. Holes seems a bit dry and this mass dont grow in them. What is your opinion? Look at the pictures.

    Hi Vaclav,

    welcome to the forum and great to see your bags. I think you are right in suspecting bad air exchange as the problem.

    From the photos it looks like a combination of the coffee mix being too dense/compacted and also a lack of air exchange.

    With the next bags you make try:

    1. mixing in 10-20% pastuerised straw, sawdust pellets, or shredded card to break up the mix a bit
    2. cutting small 2cm holes every 5cm around the bag as soon as you have filled them and before they begin incubation

    This should help provide a better environment for the mycelium to prosper on the coffee grounds.

    As a side note..it looks like one of the bags (the smaller one that fully colonised all white) was about to start fruiting – did it grow some mushrooms in the end?

    Best wishes,

    Adam
