Thanks! The pressure cooker is the KEY to your ENTIRE mushroom arsenal. Once you put the brown rice flour, vermiculite and water into the jars, you boil them in the pressure cooker for 60-90 minutes at 15psi. I do 90 minutes every time no question, but an hour can generally suffice. The pressure cooking basically kills all the existing spores, mold, bacteria, germs, and ethel-methel-bad-shit in the brf/verm/water. If you dont pressure cook them, and you inject spores and put the jars into an environment that is mold productive, you want to make sure ONLY your mushrooms grow, not all the bad mold/bacteria/etc....Nice stuff you have goin on!! What is the pressure cooker used for? And what is substrate from ebay?
WIthout a pressure cooker, you'd probably lose half your jars to contamination.
With a pressure cooker, I lose exactly 7% of my jars.
To sum it up cliffnotes style, pressure cooker = sterilization part one. (Part two is a clean room or a 'glove box' where you inject spores into the jars). After that you generally dont worry much about other molds or contaminants.
On your next question, substrate for ebay, search for "mushroom jars" and/or "magic mushrooms" in eBay. You'll find jars of pre-mixed substrate already cooked ready to just inject and colonize. Substrate is the fancy term for what brown rice flour, water, and vermiculite mix. Or, it can also have other things like bird seed, horse shit, etc.... Substrate is to mushrooms as rockwool & nutrients are to marijuana. I like to make marijuana terms crossing because we're all pot growers here first and it makes more sense I hope.
Hope this helps!
