    I’ve got some questions on how you know that a bag is ready for fruiting: what are the top or key signs that a bag is ready? Related to that, how do you know where to cut the bag to facilitate fruiting? And how do you cut the bags? Are there optimal places to create holes for oxygen? Are there a number of holes one should create and should the holes be a minimum or maximum size?

    Cheers

    You’ve already answered my question in a previous reply that I’ve cut-n-pasted here, sorry for the extraneous post, and thanks for the answer.

    The best place to make the holes is directly where the white colonised substrate is. If you are using small bags, you may be best with just one cut appprox 5cm x 5cm on one side of the bag. If you are using larger bags you could cut more holes of the same size but space them apart by 10-15 cms around the bag. You can cut a X shaped hole with clean scissors or a sharp knife. Introducing contamination at this point is less likely as the coffee is already colonised by the mushroom mycelium, but it’s still good practice to keep everythiing as clean as possible.

    Best wishes,

    Great you found that post elsewhere in the forum.

    In addition to this, I would say that one way to know when to cut holes for fruiting, is to leave them in incubation for longer and see when they start to pin in there.This will gove an indication of the optimum time to move through into fruiting.

    You may find that they are actually wanting a bit longer in incubation – we often leave our bags for 5 weeks before fruting.

    In terms of size of the hole: with large bags like you are using, you could cut holes anywhere from 2cm-5cm in size, and experiment with just straight slits as well as ‘x”s. It depends on the size of fruitbodies you are looking for. Bigger holes produce bigger clusters and tend to waste more growth in the stem. Smaller holes produce smaller but more numerous clusters.

    So ,are you saying not to put even pins holes after inoculation in the bags for co2 exchange ? If so I’m guessing when you  first see flecks of white you would just  put them there?

    Hi Michael, it depends what bags you are using – if they are proper mushroom cultivation bags with a filter patch you don’t need to cut any holes until you are ready to fruit the mushrooms.

    If your bags don’t have filters then check out the reply I just left (13th June 2016) to another forum post about how you can help create good air exchange here: https://growmushroomsoncoffee.com/topic/how-full-do-you-fill-the-bags/#post-1446
