Our favourite mushroom grow bags. Extra thick (0.08mm) means less blow outs in the pressure cooker, as well as less melt-through when sealing. Easier to fold too! Use these to sterilize spawn or lab tools.

These measure 20x12x50cm, and work best to sterilize 4-6lbs of spawn. We use these bags for all our personal mycology projects as they’re reliable and easier to work with compared to others we’ve tried.

These are best for spawn sterilization, for substrate check out our 0.5 micron bags.
