High-Quality Scientific Syringe Filter for Mushroom Spawn Jar Lids
These syringe filters provide an ideal amount of fresh air exchange while at the same time preventing airborne particles from contaminating your spawn.
Color may vary.
Simply drill a 5/32 hole in a canning lid and insert the syringe filter with the narrow end snugly into the hole. Use high heat RTV silicone for an even more air-tight seal.
