Spawn Bags with filter

Set of 5 bags
Product information


Our spawn bags provide a perfect environment for fungi growth. The microporous filter patch allows contaminant free gaseous air exchange but prevents the passage of airborne contaminants. The filter is effective to 0.2 microns and is ideal for clean sterile spawn production.

These bags are widely used by exotic mushroom growers throughout the world. Regardless of the type of mushroom that one wants to grow, spawn bags provide an excellent solution to handle many pounds of substrate in a totally sterile environment with relative ease. They are easy to seal after heat treatment in autoclave for six hours at 262°F (125°C).

What you get

A set of 5 spawn bags with filter. 20 cm + 12,5 cm for gusset, 49 cm long.

How to use spawn bags

Microsacs should be handled with care. Damaged bags should be removed because of the subsequent risk of infection through even small clefts or holes.
