Not to be a stickler, but just so its known. When decarbing oil it is not necessary to vacuum purge your oil, vac purging is used to remove solvent residuals but the decarbing processes requires one to heat the oil to temperatures well above those required to remove all solvents. One should be observing their oil when decarbing and will notice the solvent bubbles are different than the co2 bubbles which form as a result of the decarb process, one determines the state of the decarbing oil by observing the rate of co2 bubble formation. Solvent bubbles will form and dissipate before co2 starts to form.RSO is archaic and there are much better forms of medicine out there now. I recommend a decarboxilyated Amber Oil that has been vac purged.

When wanting to keep your oil in carboxylated form a vacuum purge is nice.
