I think for what you want mushrooms would be a nicer fix. I would buy Paul Stamets's 2 books on the subject and I believe he had to drop the magic mushroom emphasis that was basically what all his earlier versions were about. www.agaric.com.tw
can sell you the spawn to start, then you would need a glovebox or flowhood, pressure cooker, agar, and some petri dishes and you're set. Bring your own HEPA filter for a flowhood and I would suggest these guys: http://www.filtera-b2b.com/businessfilters/hepa.htm#99.99wood
The mushroom substrate can then be reused for compost. The large mushroom growing farm near me gives their spent substrate away to a fertilizer company. I was kind of shocked that they didn't reuse it for oyster mushrooms. Either they don't know or it's not financially viable.
This is probably the company I will be selling to: http://www.tw-mushroom.com.tw/index.php
