Medium Mushroom Grow Bag
[0.5 micron filter]


This 'medium' sized, autoclavable mushroom filter patch myco bag measuring 5" x 4" x 18" with gusseted sides and a 0.5 micron filter. This bag is composed of 3.0 mil thick polypropylene plastic. This 'medium' sized bag can comfortably hold three (3) quarts worth of material (in volume), while still leaving enough room to perform any standard procedure on the bag without the contents (grain/substrate) compromising/encroaching on the filter patch. The 0.5 µm filter is ideal for both spawn and substrate production. The filter is located at the top of the bag, which allows for more grain or substrate to be loaded into the bag when compared to other bags on the market. The microporous filter patch allows for filtered gaseous air exchange while keeping contaminants out. You will need to seal these bags with an impulse sealer or mushroom bag clamp.

These bags are not intended to be sealed before sterilization, however they can be successfully "pre-sealed" before sterilizing if all excess air is removed from the bag, excess bag material is neatly folded around the bag, and the bags are allowed to cool slowly and completely before removing them from the sterilizer. If the pressure cooker/sterilizer being used lacks an internal liner, caution should be taken to avoid contact with the internal walls of the unit, as the higher temperature retained by the walls can melt the bags.

I really love these bags. I started using them when I was a noob pressure cooking large amounts of corn for later inoculation with either GT or Golden Oyster. I will be buying more now for sterilizing large amounts of whole oat grain (best grain spawn in my opinion)
