In order to grow spawn successfully without too much fear of
contamination, there must be a safe way to exchange gasses while the
mycelium grows. The only way to successfully do this is by using
synthetic filters or bag with filters affixed to them.
Synthetic Filter Disks
|
These filters facilitate clean air exchange and
are designed to be
placed inside the lid which should have a 1/2" hole drilled into it.

Autoclavable Plastic Lids

After a 1/2" hole has been drilled into the middle of the
lid, a synthetic filter disc is inserted into the lid to allow for clean air
exchange. Used on jars for grain spawn production. These lids come in
2 sizes only: 70mm & 90mm

through the filter patch while preventing contaminates from entering the
bag. Ideal for use in the production of grain and sawdust spawn.
