Processing at home is now legal in California, you get that harvest, you can run it indisputably with ethanol or CO2 (I think you need a state approved closed loop system). I'm unsure, but I would guess (I'm gonna investigate) if using chilling techniques with liquid nitrogen are allowed too (hard to see why not). I'm seeing some very very nice results online with some gorgeous looking terpy oils. I know ideally a rotovap is the ideal method of purging. I was wondering if it's possible to purge in a vac with the slab spread ultra thin at a lower temp? Or is just the rotovap the way to go? Thanks.
