    So I’ve got a 4 tier greenhouse set up for fruiting and have had a couple of bags fruit which is great. But towards the end of fruiting I noticed a really bad odour from it, I wondered if it was not getting enough oxygen or if it could be something else? There didn’t appear to be mould in the bag and looked like it should. Is it normal for it to be smelly? the mushrooms themselves seemed fine.

    Hi Leisha, it’s not normal for grow bags to smell but it can be a sign of a bacterial infection…this is often harder to spot visually than mould, but apart from the bad smell it also often turns part of the the substrate a brown/yellow-ish colour in places…are you able to post a photo so I can take a better look for you?

    Hi Adam

    Sorry wasn’t sure how to attach photos in the forum.

    Here is the latest bag, the original one that was quite bad I had already tossed out. I thought the yellow was just that liquid waste metabolites you had mentioned in another forum post. To be honest though, I hadn’t washed out the greenhouse since the smelly bag and I have noticed that the temperature has been getting into the 20’s during the middle of the day in the greenhouse.

    Cheers,
    Leisha

    Hi Leisha,

    Thanks for sending through the photo. Yes it can be hard to distinguish between the metabolites and bacterial infections – although the smell is probably the main indicator, and also the fact that the actual substrate itself becomes a bit yellowish/brown.

    Worth cleaning out the greenhouse before you put any new bags in.

    great to see you’ve been having some success with the fruiting as well though 🙂

    best wishes,

    Adam
