If you properly pasteurize and spawn to a bulk substrate production can increase exponentially with minimal risks of contamination.. Most commercial mushroom farmers spawn to a bulk substrate.. They buy there spawn from another source usually.. Although, this was a very nice set-up.. The market for mushrooms is too unstable.. Everybody who got in on the ground floor over at shroomery and started selling supplies like spawn bags, jars and spore syringes those are the people who got a foothold in a steady market... Not to mention its a legal market...
