I must agree with mojoganjaman and canndo. Spawning to bulk is alot easier than many would initially believe it to be. Heck, you can buy a pre-made bag and innoculate it. Wait for it to colonize, and then just tell everyone that you spawned to bulk sub. I do understand what smilinjack is refering to. As far sterilization technique is concerned and how you would do it for your own particular situation. My advice is either buy a couple/few pre-made bags, or buy/borrow a pressure cooker and make like 8 jars. Innoculate the substrate. Go read more on shrooms. Then use half of your jars as pf tek, and the other you can spawn to bulk (easy as pf tek) and try a mini-monotub, then after that, try a casing. At least you will have something from pf tek. And you will feel good about spawning some to bulk. Spawning to and fruiting from bulk will help you learn alot more than pf tek. Look into "easy popcorn tek" or adding some corn meal to your jars. If you are feeling a bit daring you can check out wild bird seed. Good luck. One more thing. I have grown and consumed my own fruit very recently. I have to tell you. There is no better feeling. And you know exactly where they are coming from.
