Straw Coir Tek, have fun. I use bucket tek’d coir/verm, and mix it with jars of pastuerized manure/straw/peat substrate. Each one of these blocks is 2 lbs of compressed straw. : r/MycoRhizo r/MycoRhizo • by MycoRhizo a simple and easy to follow tek for growing mushrooms on straw. Just search on mycotopia wbs tec. Call us today. Common substrate recipes for growing mushrooms usually involve coco coir, manure, straw or hardwood sawdust, although there are many other good options to be considered. If I send it to agar then how do I transfer it to the corn after that?? I’m following a corn recipe and I’m wondering what I can use in place of the corn syrup.
