4A Autoclavable Unicorn Bags for Mushroom Cultivation
4A Autoclavable Unicorn Bags provide mushroom growers with a durable option for preparing substrate and fruiting blocks. These gusseted polypropylene bags work well for home cultivation, laboratory work, and commercial mushroom production.
Each bag uses durable 2.5 mil polypropylene and includes a 5 micron filter patch. The material handles the sterilization process used for mushroom substrate preparation. In addition, the clear bag makes it easy to monitor substrate and mycelium during cultivation.
Designed for Mushroom Substrate Preparation
These 4A bags measure approximately 8 x 5 x 19 inches. Their larger size provides plenty of room for mushroom substrate. Therefore, growers can use them to prepare fruiting blocks for many gourmet mushroom species.
The gusseted construction also allows the bag to expand as you add substrate. This design creates more usable space while making the filled bag easier to handle. As a result, growers can form practical substrate blocks for colonization and fruiting.
5 Micron Filter Patch
Each bag includes a built-in 5 micron filter patch for filtered gas exchange. The filter allows gas exchange while the bag remains closed. This feature makes the bags useful throughout the mushroom cultivation process.
Additionally, the clear polypropylene provides easy visibility. Growers can check colonization progress without opening the bag. This makes routine observation simple during a mushroom grow.
Durable Polypropylene Construction
Durability matters when preparing mushroom substrate. Filling, sterilizing, handling, and storing substrate bags can put stress on the material. For that reason, these 2.5 mil polypropylene bags provide a practical option for regular cultivation work.
The bags arrive empty and ready for substrate preparation. Growers can use their preferred substrate recipe and cultivation process. They work well for hobby growers, mushroom farms, laboratories, and other mycology applications.
Multiple Quantities for Home and Commercial Growers
4A Autoclavable Unicorn Bags are available in quantities of 25, 50, 100, 500, and 1000. Smaller packs offer a convenient choice for home growers or limited production. Meanwhile, larger quantities make stocking supplies easier for mushroom farms and frequent growers.
