i could just be going crazy.. but im pretty sure all he said was "kiklo" what are you guys talking about him ingesting mycelium and 250mg? whattt?
Ive read about people eating cakes after incubation, or doing an extract with mixed results. I dont like the idea because its hard to gauge a dose and it seems like a method for people who for whatever reason dont want to go to the fruiting stage. Theres some very covert ways using ziplock bags to fruit which will provide an ounce of mushrooms in the space of a large drawer.
Vermiculite is very fine and can pass through the stomach lining and into the blood stream where it can act like razor blade in the arteries.. Like fiberglass.. no matter what kind of filter you use, Its particles are microscopic.. If you cant get fruits then best you try again.. There is a reason that the shroom Gods wish you not to have them at the time.. Give spent cakes to the birds...
I dont know much about vermiculite, but now that you mention it it dosent seem like a good idea at all to eat. My cakes are just brown rice, so they would be safe to eat if one were so inclined, I am not.
id really rather just make an extra cake to begin with. mushroom yields are usually far more then enough for 2-3 people to be constantly cropping
