    Hi Mateo,

    We have worked in a more open-source way in the past and found that it took up all our time answering the many questions that people inevitably have. While it was fun and great to be helping people out, we simply aren’t able to spend all our time like this. As a small non-profit organisation with plenty of overheads and a big ongoing workload, the only way we are able to spend our time sharing our knowledge is to create some structure to it – we’re not able to keep up with the demands that open source creates.

    This forum is designed more as a follow up space for asking questions related to the course content. This is explained a little more in the forum rules here: https://growmushroomsoncoffee.com/topic/forum-rules-how-to-use-this-forum/

    Anyway, appreciate your feedback and hope you understand where we’re coming from.

    best wishes,

    Adam

    Hi Mateo,

    the setup of larger growing spaces and creating the right conditions in them is such a big subject that it is beyond the scope of this course and is kind of difficult to give enough detail for via the forum as well. There are just so many variables and options, and it tends to create more questions than answers most of the time.

    We’re looking at creating a full comprehensive resource covering all of this and more as a follow up course during 2016, so keep an eye out and we’ll keep you posted.

    Best wishes,

    Adam

    Hi Kaleb,

    The Unicorn bags we use in the video inside the course are the 3T bags, but we have also used some smaller 10T bags with good success. Although a bag sealer is useful if you’re sealing lots of bags, you can also just turn the tops over and then seal with paperclips or tape.

    Hi Mateo,

    We only use grain spawn ourselves – mainly because we buy our spawn in, but also when we used to produce it ourselves grain was also our preferred method. I have made liquid cultures in the past but found that unless you had very sterile conditions to produce them in that they would contaminate quite easily.

    The other thing to bear in mind when growing on coffee grounds is that moisture content can be an issue if the  coffee used is too wet so adding additional water to the mix with liquid cultures could cause further problems.

    Always good to experiment though so let us know how you get on!

    best wishes,

    Adam

    Mateo asked:

    I was wondering if anyone here has experimented with innoculating with LC’s. I figure it’s much easier to innoculate with a liquid culture than with grain since you can make liters of it at once… That is, if you make i sure beforehand that it’s a clean culture, or else you’d be growing contams and not mushrooms.

    Some people use malt, honey, karo or other syrups for the nutrient in the liquid (usually 2%) so for example 100ml would be 2 ml of honey.

    I’ve also been adviced to use grainwater from grains used to colonize (reuse/recycle) which seems like a good idea which I’ll be trying soon.

    Any tips that any of you fellow shroomers can offer would be appreciated

    Questions are welcomed as well

    Happy holidays!

    in reply to: Wood pellets to be pasteurized same pasteurized straw? #963

    Hi Marco,

    Great question! This is something we’ve been experimenting with over the last few months and we’ll add into the course material when it is updated in 2016.

    We’ve found that you can just soak in water and then add straight to the mix without pasteurising. The process by which the wood pellets are made occurs under high heat and pressure and this renders the sawdust pellets sterile. They also then contain such low moisture content that no organisms can grow on them.

    To use sawdust pellets, try to source some which are made from hardwood rather than softwood, and then soak in water until the pellets break up (this can take a while and can be sped up with warmer water), then squeeze out any excess moisture and add to the coffee in place of the straw. You can add them at anything between 10-50% of the weight of the coffee.

    Hope this helps and let us know how you get on.

    Best wishes,

    Hi Jerome,

    we used to produce all our own spawn, but it began to take up too much of our time as it is a whole other operation in itself. In our view it’s better to buy spawn from someone else who specialises in it, and then focus instead on the mushroom production.

    This was the case for us, but it’ also true when doing things on a smaller scale that it reduces costs and gives you an appreciation for cultivating mycelium and the kind of conditions it thrives in.

    As to how to do it – there are many steps involved, it can take a while to learn, and you need clean sterile conditions. There’s too much to learn to cover it here and it’s beyond the scope of the online course, but you could learn more about it in Growing Gourmet and Medicinal Mushrooms by Paul Stamets.

    Jerome asked:

    Hey Adam,

    I just wanted to know why you did not grow your own spawn? And how do you grow it?

    Wouldn’t it reduce the cost of growing the spawn your self?

    Thanks Jerome

    Hi Marco,

    I can delete the post if you wish? From the title it sounds like you were wondering what the yellow honey-coloured liquid in the bags was. Here’s a photo of something similar in the bag on the right:Yellow Waste Metabolite Liquid In Fully Colonised Bag

    The liquid is nothing to worry about it – it’s just waste metabolites that the mycelium produces as a byproduct whilst growing across the substrate. You can wash it away with water when you cut open the bags to fruit if you wish.

    Hope this helps.

    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

    Vaclan asked:

    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 there,

    Ultrasonic humidifiers are very good at creating the type of fog-like humidity that Oyster mushrooms like to grow in – just make sure you don’t make it too humid with it on all of the time though: 85-95% RH is ideal.

    Hi Andrew,

    Sorry, I have only just seen your question here – unfortunately the webinars are only available for a week afterwards with the webinar platform that we use.

    However, there will be another one at the end of February and you are more than welcome to ask any questions you have here on the forum in the meantime.

    Best wishes,

    Hi Karla,

    Great to hear you experimenting! Yes this should be fine to pasteurise the wood shavings like this, especially if they are from kiln-dried wood that a carpenter would often be working with.

    How are the bags now looking a few weeks later?

    Hi Ute,

    During the rest period between crops, you can just leave the bags in the same fruiting conditions. They will take 5-10 days ‘resting’ whilst they break down and gather more nutrient from the coffee, before fruiting again when they’re ready. It’s best for them to be in the fruiting conditions so they are able to fruit as soon as they’re ready.

    Hope this helps.

    best wishes,

    Adam
