Mushroom Fruiting Bags — Double Patch 0.5 Micron, 23.5"x10"x5.5", Qty 500

Bulk case of 500 double-patch fruiting bags. Two large 0.5 micron hydrophobic filter patches sit adjacent to each other to encourage cross air flow, so the bag breathes far better than a single-patch equivalent. More fresh air exchange means faster colonization and bigger, healthier fruits.

Extra-large gusseted bags measuring 23.5" x 10" x 5.5", made from 3 mil polypropylene — thick enough to resist the micro-tears that quietly cause contamination in thinner bags.

Specifications

• Double 0.5 micron filter patches, positioned for cross flow

Why 0.5 micron: the larger pore size moves more air, which is what a fruiting block needs. For grain spawn, where you want tighter filtration through a longer sealed incubation, use our 0.22 micron spawn bags instead.
