10x 565ml PF-Tek substrate jar
A pre-sterilized 565ml filterbox filled with a substrate according to the PF-Tek. This substrate jar comes with two self-sealing injection ports. One of the other advantages of these ports is that they make it possible to inject the spores at any non-sterile place, without having a high risk of contamination. Just clean these ports with some rubbing alcohol before injecting. Do not enter the injection port with a hot needle this might damage the injection port.
