Mushroom Grow Bags

This is the full factory case: 1,000 Unicorn medium 10T bags, the same 5" x 4" x 18" gusseted bag as our 50-pack at case pricing. At 3 to 4 pounds of grain per bag, one case runs roughly 3,000 to 4,000 pounds of spawn, which makes it the right buy for farms, labs and spawn producers filling bags every week. Unicorn bags are made in the USA by the company that created the filter patch spawn bag. The film carries pliability additives so it stays flexible after sterilization instead of...

Unicorn medium 10T bags are the grain bag most growers learn on: a 5" x 4" x 18" gusseted bag with a 0.2 micron filter patch that holds 3 to 4 pounds of hydrated grain. That is enough to spawn a tub, light enough to break and shake by hand, and small enough that one contaminated bag doesn't sink a whole run. Unicorn bags are made in the USA by the company that created the filter patch spawn bag. The film carries pliability additives so it stays flexible after sterilization instead of...

Unicorn large 3T bags are the big-batch grain bag: 8" x 5" x 19" and gusseted, holding 5 to 6 pounds of hydrated grain or substrate with a 0.2 micron filter patch. Fewer, bigger bags mean less filling and handling per run. Unicorn bags are made in the USA by the company that created the filter patch spawn bag. The film carries pliability additives so it stays flexible after sterilization instead of stiffening, and the bottom seal is built to hold up to the shaking a grain run takes. 50 bagsPer...

Blue Myco XLS double patch bags are built for fruiting, not just colonizing. Each 10" x 5.5" x 24" gusseted bag has two oversized 3.8" x 3.8" filter patches rated 0.5 micron, about 29 square inches of filter per bag, so a big block gets the air exchange it needs once it starts producing mushrooms. Fruiting bodies burn oxygen and give off CO2 far faster than colonizing mycelium. A small grain-bag filter can choke a fruiting block; two large, more open patches keep the air moving so you can...

This is a full case of 800 Blue Myco large 3T bags: the 8" x 5" x 19" gusseted bag in a heavier 3.0 mil film, at case pricing for operations that fill bags on a schedule. The thicker film takes aggressive sealing and repeated handling through filling, sterilizing and incubation without micro-tears, stays pliable after sterilization, and has a reinforced bottom seal. 800 bagsFull case 8" x 5" x 19"Gusseted 3.0 mil80 micron film 0.2 micronFilter patch ReinforcedBottom seal Why growers pick Blue...
