PP5 (polypropylene 5) mushroom spawn/grow bags (10 pack)
These are autoclavable/pressure cooker stable PP5 bags for grain spawn production and fruiting. They are 12 inches wide x 18 inches tall. The opening is at the top of the bag. Non-gusseted. Very easy to seal with an impulse sealer or lighter (fold over to make a seam and melt gently), or staple the top after folding over a few times (see product images). These bags don’t have a filter patch, but they work well for up to 2 pounds of grain spawn. If being used as a fruiting bag, cutting the top and using diaper tek with a monotub or grow tent would be advisable.
