Description
4T Autoclavable Unicorn Bags provide mushroom growers with a dependable filter patch bag for grain, substrate, and mushroom cultivation. Boise Mushroom Company offers these professional-quality grow bags in several quantities, making them practical for home cultivators, small mushroom farms, laboratories, and larger production operations.
These gusseted polypropylene bags are designed for the high-temperature sterilization processes commonly used in mushroom cultivation. In addition, their clear construction makes it easy to inspect grain or substrate throughout preparation and colonization.
4T Autoclavable Mushroom Grow Bags
Each bag includes an integrated filter patch that allows gas exchange while helping the contents remain enclosed. As a result, growers can use the bags for sterilized grain, supplemented hardwood substrate, sawdust blends, and other mushroom-growing media.
The gusseted design also provides useful interior space. Therefore, the bag can expand as it is filled while remaining easy to organize inside a sterilizer, incubation area, or mushroom growing space.
Designed for Mushroom Cultivation
These 4T bags work well through several stages of mushroom cultivation. Growers can fill them with prepared grain or substrate, sterilize the material, inoculate it, and monitor colonization through the clear polypropylene.
Because the filter patch is already installed, growers do not need to add a separate filter. The design keeps preparation straightforward while providing the gas exchange needed during colonization.
Multiple Quantities Available
Choose from packs of 25, 50, 100, 500, or 1,000 bags. Smaller quantities work well for hobby growers, testing projects, and occasional cultivation. Meanwhile, bulk quantities offer a convenient choice for farms, commercial growers, laboratories, and anyone preparing mushroom bags regularly.
The quantity options also make it easier to purchase the amount that matches your current production needs without changing to a different bag style.
Durable Gusseted Polypropylene Construction
4T Autoclavable Unicorn Bags use durable polypropylene designed for mushroom cultivation applications. Their gusseted shape provides room for grain and substrate while helping growers efficiently arrange filled bags during processing and storage.
After sterilization, the bags can be sealed according to your normal cultivation procedure. The clear material also allows quick visual checks without repeatedly handling or opening the bag.
