I don't see the point in vac purging. What is your opinion on the benefits of vac purging?
a 99.5+% clean purge in about 2-4 hours (after the initial hot plate purge). it basically pulls out that remaining 1% or so of shit.
you dont realize how awesome the vacuum is till you have one, it basically speeds things up 10x faster.. turning a 48+ hour purge into a 4 hour purge.
I can take your oil, that you would bet your life on that its 100% purged, throw it in the chamber, and it would prob muffin up quite a bit (muffins are from solvents escaping most of the time) ... hence not being fully purged (no offense) . its VERY hard to purge without a vacuum ive found, or it just takes forever which im not fond of.
ive done everything, double boil for days, while whipping every few hours, in a thin layer for 48+ hours on heat the whole time.... I once had a fan sit on my oil for 2 weeks straight, while I went on vacation... posted some pics and people said it wasnt fully purged... I was offended at the start but finally came to admit, they were right. I would still only rate it roughly 98% purged at that point, which for many, would be good enough. but I find the vacuum is amazing for final purging, especially everclear...that stuff is not easy to evaporate. butane is easier though.
the negatives are:
costs 250$
can suck terps out of the oil
and if you forget to close valve, it ruins all your oil.
I originally bought the vacuum to make wax... the wax fad lasted about 2 months before I was sick of it (its not as great as everyone makes it out to be.. tastes like shit and hard to handle on dabber + takes me 7 days in the chamber) now, I LOVE using the vacuum to final purge my stuff, and make some true shatter tha has ZERO funny tastes, perfectly see through, rock hard, completely silent on the nail... it actually resists the nails heat for a few seconds because its such a solid/dense chunk.. basically "pure thc"... no waxes, no solvents, etc...
ps: these percentages are not exact...theyre just some random numbers I used to help me explain it.
