You can purchase from mycosense<\/a>,\u00a0fungi.com, etc. I recommend mycosense<\/a>\u00a0because they are a small attentive\u00a0company, and they are really into this process and work.\r\n\r\n100 cup coffeemaker with a thermometer is convenient\r\nbut a large canning pot on a stove\u00a0would do\r\n\r\nnut\u00a0bags (or other mesh bags) to pasteurize substrate (easy to squeeze water out)\r\n\r\na press to squeeze substrate would be nice, esp if you are making a lot of it\r\n\r\nsubstrate: coffee chaff, oat straw, rice husks - depends on texture you want\r\n\r\nmolds to\u00a0form substrate (I've been making test bricks in hinged polyethylene containers)\r\nwill need to provide\u00a0an air hole\r\n\r\npolyfill or cotton bags to make an air filter fo the hole - keep contaminants out\r\n\r\nzip locks (if you are using a very porous mold\u00a0(i like perforated molds for texture) you will want to place porous mold in a zip lock to keep moisture in\r\n\r\nfreezer tape and sharpie to label molds\r\n\r\nspray bottle with 70% alcohol (should be 70% - you don't want to kill everything)\r\n\r\npaper towels or alcohol wipes\r\n\r\nvinyl disposable gloves\r\n\r\n \r\n\r\nSteps:<\/strong>\r\n\r\nheat water to 160\u00ba\r\n\r\npasteurize substrate for 10-15 minutes\r\n\r\nclean all work surfaces and mold interior and exterior with alcohol and dry\r\n\r\nwash hands and arms with\u00a0soap, wear gloves for the next steps:\r\n\r\ncool substrate until you can handle it\r\n\r\nsqueeze all excess water from substrate (you want it moist but not dripping at all)\r\n\r\nput air filter into hole in mold\r\n\r\nmix grain spawn with substrate; there are 2 ways to do this:\r\n\"lasagna\" method of layering substrate then spawn, or\r\npremix 1:5 spawn:substrate\r\neither way, the ratio is about 20%, might be less needed\r\n\r\npack mold with spawn\r\n\r\nkeep somewhere between 70\u00ba - 80\u00ba\r\n(I keep my molds\u00a0in a loosely closed cardboard box to prevent contaminants drifting\u00a0in the air or falling from the ceiling)\r\n\r\nYou should have a pretty solid material after 6-12 days\r\nIt will look very white and fuzzy\r\nRemove from mold\r\nDry in open air (it should no longer risk contamination at this point) for 3 days or until dry to touch\r\n\r\nBake in over at 150\u2022 - 200\u00ba for 60 minutes to render\u00a0mycelium inert.\r\n\r\n \r\n\r\n ","type":"rich"}
