Our straw based sterile mushroom substrate formulated by mycologists for straw-loving species like Osyer mushrooms. Oyster mushrooms grow very well on straw and are the best species to grow on straw. The combination of micro-to-macro particle sizes of premium grown straw and wheat bran helps to speed up growth and maximize yield.
Note: substrate is hydrated to field capacity.
Use in monotubs, or experiment with trays, buckets, and containers in a humidity-controlled grow room or Martha set up.
Each bag contains at least 1800 grams of substrate mix.
Spawn to bulk ratio:
We recommended mixing 1 colonized grain spawn bag with 2-3 substrate bags. Higher inoculation rates may improve your success.
