Filter Patch Mycobags (10 count)

Klarna worked like a charm. Quick and easy! Shipping was surprisingly fast.
MMM is my go-to shop for myco supplies and spores.

Not too big not too small

Large good quality bags

Worked great for preasure cooking substrate for my pink oysters

If you want to make bulk substrate that you can't pasteurize, these bags will survive a pressure cook. Just fill it up with your mix, seal it up, and cook away. The bags will come out still sealed and intact and; once cooled down, ready to be mixed with your favorite spawn to be colonized. I tossed these bags in with my second order through MMM and mailed the mushroom man a certified envelope full of cash. I go this option because who doesn't love freebies? I assure you it's legit. Nobody gains this level of recommendation on Reddit or the shroomery forums if they ain't for real.

Great for PC'ing substrate, even if you want to pre-seal your bags before sterilization. I have some king oyster spawn colonizing away in these right now, any it's happy as can be!
