These substrate bags come ready to use. Simply add your desired grain spawn and allow to colonize. Inoculation with grain spawn (grain that's been colonized with your chosen fungus) is highly recommended. We do not recommend inoculating with agar or liquid culture. 

You can purchase a grain bag here to make your own grain spawn first!

Supplemented hardwood substrates are ideal for wood lovers like Lions Mane, Maitake, Oysters and many others. We use a 50/50 mix of Oak Hardwood and Soybean Hulls in our substrate bags. Our substrate contains the perfect amount of water for awesome flushes. 

This 50/50 recipe of soybean hulls and sawdust often been referred to as Master's Mix as named by T.R. Davis of Earth Angel Mushrooms.  

Option of either 5lb or 10lb sterilized bag of pre-sterilized soybean hulls and oak sawdust.

  • Hi - Are your hardwood substrates sterilized?

    Our hardwod substrate comes ready to use! We steam pasteurize our substrate like all other commercial suppliers. Some may call them "steam sterilizers" but that's technically not true unless pressure is involved. Sterilization requires pressure to raise the boiling point of water so that higher temps don't cause it to boil off. So, technically speaking, without pressure we are ultra-pasteurizing our substrate. Now, this does NOT hold true for grain and agar. Those must be sterilized using an autoclave or pressure cooker simply due to the large amount of sugars.
