No lid because we had trouble with jars breaking, I assume due to pressure. Lid is not needed with the force.
We use an old school thermo that’s pretty big. Holds 1qt masons that we use to spin.
I just use rpm, but I’ll take a look at what the equivalent is next time I use it.
We tend to cold cure but have been playing around with this method to cut down cure time on the more stable resin.
We also spin sugar with a mesh basket in the mason jar to separate terps on bho from time to time.
