So you guys are talking about 12-24 hours as a starting point? I assume you need to keep the heat on it the entire time. But the vacuum can I just lock the valve off and turn off the machine? Or do I need to run that for 12-24 hours?
the bigger the run you have, the more solvents(bubbles) you will have escaping. these solvents (BUBBLES) will fill your chamber up with gas, so you will need to re vac to get desired hg, OR bleed the chamber at desired level...
ok, so the oil still has its mysterious corners, but here are some charts i hope many really gain from
Top chart shows what we want. and what not to approach when applying heat, and/or vacuum with time.
fresh material (thc) can handle higher temps and vacuums, without decarboxylating. (decarb = turns shit into goo for life)
that being said, many people dont have access to that, and try to make old trim into nice oil, although it is possible, its damn hard, so slow and low is the go.. (or high heat goo for life is simple)
i recommend everyone who is making oil, and has some sort of connection with the source(or is the source) to tell them :fresh properly stored material produces the prettiest, smelliest extract.
now onto the bottom chart. when removing the solvents with a vacuum.
our goal is to remove the solvents, water/butane/alcohol
i think the best way to go about a safe extraction without killing your thc, is to start off at the minimal boiling points with vacuum. and judge the entire purge by the action of the bubbles being released.
my belief is in the bubbles. they tell you a lot. the big ones mean you gots a long way to go. the small ones mean you are on the final stretch :]
ALSO, when applying heat/vacuum, the higher the temps you go, the more sped up the process is. meaning, with heat, its basically like a VCR on fast-forward, and you want to stop and turn it to slow motion just before the good part!!!!.. you dont want to fast-forward through it, or else you will NEVER see the same thing you passed. ( but you will still have a good goo for life)
cheers!!
its alll in the bubbles, and an even purge.
