Multi Grain Mushroom Substrate Bag - 1lb
The 1lb Multi Grain Mushroom Substrate Bag contains hydrated, sterilized popcorn, red milo and rye berries, ready for inoculation with your chosen mushroom culture. Use this smaller bag to grow one culture through a mixed-grain batch before transferring the colonized grain to a compatible bulk substrate.
The bag has a self-healing injection port and a 5-micron filter patch for gas exchange. Keep the seal closed during inoculation and incubation, and leave the filter clear.
For a spawn-based grow, allow the grain to colonize fully before transfer. The linked manual also covers growing in the bag when that method suits your mushroom.

Bulk substrate for colonized multi grain
Choose bulk substrate for colonized grain according to your mushroom and growing method.
- Compare manure substrate, pasteurized straw and wood-based substrate for the next stage of your grow.
- Use casing soil as a surface layer when your method calls for it. Button and portobello mushrooms also require properly prepared Agaricus compost beneath the casing.
