Description
14A Unicorn Bag is a 2.5 mil polypropylene gusseted mushroom grow bag with a 5 micron filter patch. Designed for mushroom cultivation, this durable bag provides space for substrate while the filter patch allows gas exchange during colonization and fruiting. Choose from quantities of 25, 50, 100, 500, or 1,000 bags.
14A Unicorn Bag with 5 Micron Filter Patch
The 14A Unicorn Bag is made from durable 2.5 mil polypropylene. Its gusseted construction provides useful interior space while maintaining a practical shape for mushroom cultivation. In addition, the integrated 5 micron filter patch allows filtered gas exchange without requiring the bag to remain open.
This bag measures approximately 8 inches by 5 inches by 19 inches. Therefore, its size provides room for larger substrate preparations and mushroom fruiting applications. The gusseted sides also expand as the bag is filled.
Designed for Mushroom Cultivation
Grow bags provide a convenient container for preparing and managing mushroom substrate. The 14A Unicorn Bag combines polypropylene construction with an integrated filter patch in one cultivation container.
Because gas exchange is important during mushroom cultivation, the filter patch allows air movement while the bag remains closed. This makes filtered grow bags useful for maintaining an organized cultivation workflow.
Durable 2.5 Mil Polypropylene Construction
The 2.5 mil polypropylene material provides a balance of flexibility and durability. Additionally, the clear bag makes it easy to observe the contents without opening the container.
The gusseted design expands as material is added. As a result, growers can fill and arrange substrate more easily than with a flat storage bag. The rectangular shape also makes filled bags convenient to arrange on shelving.
5 Micron Filter Patch
The 14A model uses a 5 micron filter patch. The filter is positioned on the bag to provide passive gas exchange during the cultivation process. Meanwhile, the remainder of the bag provides an enclosed space for the prepared substrate.
For Unicorn Bags in our product selection, models ending in “A” use a 5 micron filter patch. This makes the filter specification easy to identify when selecting bags for your cultivation setup.
