World Seed Supply proudly serves our mycology enthusiasts with these LARGE gusseted autoclavable spawn bags (approx. 19″ long x 8″ wide x 5″ gusset). These bags are fitted with a microporous filter that allows for gas exchange while blocking contaminants. These bags allow for bulk substrates to be sterilized within the bag. They can be used with any substrate, including hardwoods, grains, compost, manure and even straw. Upon inoculation, spawn can be incubated within the bag without contamination from the outside ruining your project. Bags can be sealed with an impulse sealer or an iron. Some growers will choose to tie the bag with wire or use clothes pins. Many growers will also choose to carry out the entire cultivation process inside the bag. This process of colonizing and fruiting a substrate within the bag is called growing in-vitro. We have a more porous type of filter (5 micron) specifically for growing in-vitro that allows for the greater gas exchange needed in the later stages of growth. In some instances, these bags can be used more than once. Please be aware that these bags are empty. The bag in the picture is shown filled as an example.
