  • @verayadon for a few reasons. I want my entire pasteurization process controlled. It takes a good hour for the tank to fill. If I were to put straw in the tank and then fill I would be heating some of the straw for over two hours and stuff towards the top an hour. I do get some heat loss that I am accounting for where i get 175 degree water comes out and i want it at 160 or below. 175 is too hot for the straw to pasteurize in while it slightly cools, before I get all 100lbs in.

  • @bjyoder1 it might work, the mycelium is going after the the cellulose and breaking that down to covert it into the mushroom fruit body. I think cereal grain straw has more of what the mushrooms need than hay would offer. I have never come across any production being done with hay.

  • Can I use old hay instead of straw?

  • like your video. but why didn't you add the straw to the tank before you filled it with hot water?
