We run our solvent at -40, sometimes -30. We have capabilities to cold inject over dry ice/ethanol slurry as well and also just got an open sleeve de wax column for our live resin. When you say run cryo, are you just refferring to running your solvent as cold as possible? Or de-waxing as well? A buddy of mine said he had his slabs immediately start coming out dark from the T4 they use.
Ever have issues with the motor burning out? Is it common?
