This is very true, I think at the best I got it down to losing 1 in 10 jars.
Personally, for a 101 level class I would recommend starting with Oyster mushrooms and PFtech rice cakes for the substrate. Oysters are very fast and strong colonizers that can often out race and compete contaminants and the rice cakes can be fruited as is in a simple terrarium or crumbled and added to straw/paper/woodchips/dowels to increase the bulk for fruiting or to inoculate logs.
I have a nice big pressure cooker in storage and I think I have some filter bags too but I’m not sure how many. I think we should be moving and able to get into the unit in the next month or so, I think all of my current spore collection are “FOR MICROSCOPY STUDY ONLY” species, but can 100% guarantee that if one hooks up with some of the internet mushroom forums (the above mentioned shroomery is one but personally I liked the community at mycotopia.net better as it was slightly smaller and had fewer trolls) and says they are looking to teach a class at a Makerspace you will be able to get some prints, liquid culture, agar culture, and/or live spawn at no charge.
It’s a pretty good list. I’d add a big bag of pearlite and a bag of vermiculite(make sure to get this one from the insulation section NOT the gardening section to avoid a huge markup,) and a few packs of syringes( i usually would buy the big cattle injectors from farm and fleet as the larger gauge needles got clogged less when using them with LC’s
I really would like to see this happen at the space, if I can be of any help please let me know. After being cleared to use the science equipment and a practice batch or two I wouldn’t hesitate to teach the class( more realistically a series of classes) myself if @triggerscold doesn’t want to shoulder the whole load.
