Injectable Spawn Jar Lid
Widemouth - 90 mm

These lids are outstanding. I only bought 2 and both my jars innoculated perfectly with extremely healthy growth. The red silicone indeed seems to be pressure-cooker safe, it heals well, and the filter is attached by dried liquid red silicone as well. A little hard to position the needle once inserted but I simply rolled my jars a little after injecting rather than worrying about injecting against the side of the jars, and it's doing fine. My jars personally took a week to show any signs, but I think this is because the filter is very thick, which is fine with me because it has kept my jars crystal clean with zero contaminants. Now they're half colonized at 2 weeks. Slowly but perfectly. I can't say enough about these lids and I'm DEF buying more. I'm not fooling with anything else when my first two jars I've ever spawned have done this good!

Extremely high quality, I haven't found a better lid yet. I have a feeling that these will last for many many inoculations. They sometimes loosen a bit in the pressure cooker so make sure to tighten them when you pull them out.
