Fungi love grains, all seeds & cereals. Milo or Sorghum bicolor is great for mushroom cultivation. Easy to prepare & a nice uniform size grain for spawn. Lots of the nutrition fungi enjoy doubles in volume during hydration. Red sorghum is our grain of choice and we only use food grade organic.
Recipe Tek for perfect hydration of sorghum is achieved by soaking in an insulated cooler box with boiling water for 24 hours & then strain for 3 hours until almost dry to touch. To stop grains clumping (plus a little extra calcium) add a handful of gypsum & calcium carbonate.
