Yes I do have a miner for heating, but it hasn’t been on much lately. The freeze dryers and other equipment I have in there generate a lot of heat when they are operating, and now the weather is warming up quite a bit.

Sure, when’s that? Send me a DM.

The mycelium does have plenty of good stuff it, but you would only want to use mycelium grown on brown rice flower or something similar. Many lions mane supplements are made from myceliated brown rice. But you wouldn’t want to use a big sawdust substrate for that.

yes you can extract psilocybin from fully colonized media, it is present in roughly the same proportions in all parts of the fungus

in the netherlands they bypass laws against selling fruit bodies with a modified growing regime that causes the pins to abort growing into mushrooms and instead you get "truffles" which are basically amorphous blobs of mycelia that wanted to become mushrooms. i think the trick is darkness and slightly lower humidity.

i should add that extracting psilocybin can be a bit tricky and the product is quite unstable and won't last long. also, if you use the same technique on dung lovers it is full of urea and stinks like piss, and is a golden goo sorta substance.

i wouldn't be able to say what is the best way to do it but i think isopropanol is the best solvent, you want to dehydrate the colonised media thoroughly, at cool temps (use calcium choride) and dry your isopropanol with baked epsom salts, then filter the epsom salt out of it (doesn't take much, once you drop the powdered dehydrated salt in and it doesn't glom up the iso is dry). isopropanol is the best because methanol and ethanol, especially ethanol, cannot be dried like this and the water reduces the durability of the extract. suffice it to say you want to store it in the freezer, also. i think it's possible to mix it with gelatin or agar to make jellies so you can dose it adequately, it's fairly strong stuff by weight, 2-10mg of the extract is enough to send you to fairyland.
