Grow straw-loving mushrooms!

Our straw based 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.

This straw substrate comes dry, with no water added. To prepare it, simply pour boiling water directly into the grow bag(included) to pasteurize the substrate, or use a cold pasteurization method if preferred. Just add 1,200mL of water, and the substrate will gradually absorb it, making it ready for use.

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 700 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.
