Zipper Filter Mushroom Bag Medium - Sac O2 - PP75/SEH6/V32-49
Polypropylene Zipper Filter Mushroom Bag Medium
Finally mushroom bags from a sister company of the biggest spawn producer in Europe. These bags were specially designed for Pleurotus and Shiitake mushroom spawn production and substrate blocks. These bags can only be described as the most advanced mushroom bags of the world. I have never colonized spawn this fast.
The filters never stick/melt in the pressure cooker as the Unicorn bag do.
The filters are not weak and you do not end up ripping them as the Unicorn bags do.
The filters are not made from PTFE as the unicorn bags are.
