Anyone using Sous Vide for cannabis decarbing?

@Myrrdin

Vacuum really helps

How? (does it depend on where you’re going NEXT?)

Agitation?
Devolatilization?
Contrary to rumor, it does not lower decarb temperature

@cyclopath

vac does not change decarb temp or time.

@borysses

Agitation helps with heat distribution and vacuum with degassing. Movement of gas bubles could be considered agitation but the same bubles affect the heat transfer in a negative way. The energy reguired for decarb is the same regardless of pressure.

This idea is reasonable, but there are a few very important caveats and notes that you must know before doing it: Pressure does not significantly affect the decarboxylation reaction kinetics, so it should proceed at normal temperatures and times, even under pressure. With enough pressure, you may find you can get away with slightly lower temperatures, but there are severe limitations on that, as described below. Of course any pressure applied should be devoid of reactive compounds like oxyg…

@cyclopath

MgO or other catalysts can change that energy requirement. Presumably an enzyme can be had as well

pulling vac does have other advantages: it can give you more head space to decarb in a sealed container. it also removes all that nasty oxygen that might otherwise attack your carefully bred/grown/extracted secondary metabolites at elevated temperatures (you know, if you’re trying to Decarb under pressure to retain terps?) and don’t feel like spinning them off before decarb.
