6 pc. 'Regular Mouth' Culture Jar Lid with Port & Filter – North Spore
Autoclavable Plastic Jar Lids with Injection Port and 0.22 micron Filt – Sporogenesis
Jar modifications with injection port and/or syringe filter-any advice? Should I just use a micro pore tape for gas exchange instead of syringe filter? Thanks! : r/shroomers
