Silicone oil (or avacodo oil, or so I hear. Wanting to experiment with avocado oil myself) in the bath, 125c, <150 torr vacuum, 30 minutes or until bubbles stop. Some say to crank it to 145 for 10 minutes, but others seem to cringe at that temp with such a weak vac, so best to play it safe in my book. I don’t think anyone can give you a precise SOP without knowing other variables, but those guidelines are a good place to start experimenting.
Just remember, vacuum does not speed up the process or lower the decarb temp. Most just use vacuum to limit air exposure at those vulnerable temps. I myself am trying to find a way to run the exhaust vac through some charcoal given the pungent terp smell decarbing can release. Last thing I want to be doing is attracting thieves who happen to be walking by and getting ideas for later on that night.
