"The first picture describes how to make your own filter bags using common materials: the cap of a needle with one end cut open, and the other with Red RTV silicone glue on end so it is a self sealing injection port. Anything would work though, a small metal, glass, or plastic tubing or pipe.
Then you just wrap EZ felt or some other polyester like... fiber sheeting around it. Tape it together to stop it from unrolling, and then put in the bag. Ziptie the bag so it's a fairly snug fit, and you're good to go! You own spawn bag with an injection port!
Then the next picture we all saw recently, but it's a good reminder for what could be done with this self made bag. Automatic injection syringes could inoculate hundreds of bags with just one liter of liquid culture. All you need to do is point and aim. They have a spring in them that pushes the Plunger back up as it refills the syringe via a one way valve." CR
I had a couple of questions: Where do you get non filter polypropylene bags that are autoclavable? Will the Syringe plastic cover withstand autoclaving? i would guess that he is injecting liquid culture so these would be grain bags and not sawdust bags (slow or delayed colonization) unless you did a combined all- in- one bag tek (grain and sawdust) ala Peter McCoy's description in his treatise Radical Mycology. What kind of mycelia is the guy using? Oysters vs. others, very important
