Large Mushroom Grow Bag - [Extra Thick 3.2 mil] [0.5 um Filter]

This large sized mushroom grow bag features extra thick plastic (3.2 mil), measuring 8" x 5" x 20" with gusseted sides and a 0.5 micron filter. This bag is manufactured in China. Some growers prefer this China-made bag over its USA-made equivalent for its extra thick, 3.2 mil plastic. Although thicker than our USA-made bags, the downside of these China-made bags is that the filters are not composed of the same material as our USA-made bags. The Chinese filters can be prone to tearing during sterilization. We recommend ordering a small quantity of these bags to test with your application before ordering a larger quantity.

This extra thick mushroom grow bag features heavy-duty 3.2 mil Polypropylene plastic, providing more reliability and less contamination when compared to other myco bags. This 'large' sized bag can comfortably hold seven (7) lbs. (weight) or quarts (volume) worth of material, while still leaving ample room to perform any standard procedure on the bag without the contents (grain/substrate) coming into contact with the filter patch. The 0.5 µm filter is ideal for both fruiting and sterile spawn production. The filter is located at the top of the bag permitting for grain or substrate to be easily loaded into the bag without compromising the microporous filter patch, which allows for filtered gaseous air exchange while keeping contaminants out. This spawn bag is pliable at any temperature, before or after sterilization. The bottom seal of the mushroom bag can withstand substantial agitation when breaking up your spawn or substrate. The bag opening is designed for easy sealing with an impulse sealer or mushroom bag clamp.
