High strength, autoclavable filter patch mushroom grow bags. Used for making mushroom spawn, or sterilising substrate for making fruiting blocks.
These versatile grow bags feature a 0.2 micron filter patch to allow FAE (fresh air exchange) whilst keeping contaminants out! This is crucial in the growth of healthy mycelium.
At 0.06mm thick these bags are pre-sealable, so you can seal with an impulse or vacuum sealer before sterilising.
