Unicorn 4b Small Mushroom Grow Bags 10x 5 micron FREE USA SHIPPING

July 9, 2026

This auction is for 10 autoclavable Unicorn 4b mushroom grow bags. The b patches can be pre-sealed before sterilization without worry of rupturing due to the larger micron patch pores. This is a handy feature if you plan to sterilize and inject straight through the bag if you don’t have a flow hood. They are smaller bags generally used for grow kits or grows that need more fresh air exchange. I am an authorized unicorn bag distributor, have confidence in placing an order!DescriptionType: GussettedMaterial: 3.0 Mil PolypropyleneBag Size: 4″ X 3″ X 18″Filter Type: AFilter Size: 1.5″X1.5″Filter Pore Size: 5 micronsFilter Hole: Style L This bag is identical to bag Type 4-A and bag Type 4-T except that it has a Type B filter.This side-gusseted breathable bag gives a sturdy stand-up bag after filling and a strong bottom seal.
