Set of 25 bags per offer (select larger sets below for bulk discount). Microporous filter patch allows contaminant free gaseous air exchange. Ideal for spawning grain, sawdust, or straw. In many cases the bag can be used as a fruiting container.
Bags now feature a thicker wall of 3mil, compared to other "standard" 2.5mil wall bags. Thicker bags require more material, and material costs are rising in all industries, but we will continue offering these bags as cheap as possible. Note the new "case" size has been reduced to 800 bags.
New model filter design allows bags to be presealed before sterilization. Measures: 18" high * 8" wide * 5" deep.
