I use hexane on trimmed bud, very very dry, gotta be careful it falls apart into dust dry. 45 seconds to a minute mashing violently in a pouring cup, then pour through a coffee filter.
That was easy.
The cheapest vacuum pump that would pull enough vacuum fast enough cost $750 on sale over the internet. Cannot get the hexane out without the vacuum.
Heat to slow boil, 175 degrees. When the bubbles almost completely quit showing, 90 minutes with 35 watts for 10 oz in my setup, put the vacuum to the container, it should begin boiling quite rapidly, way faster than the simmering it did earlier. Five minutes vacuum, five minutes rest, five minutes vacuum, etc through four cycles and it does not bubble under vacuum anymore. Clean enough to smoke now.
I don't remember the original numbers, been years, but the vacuum is enough to make straight hexane boil at 120 degrees. Down from 170. The thicker the mix gets the higher the boil point goes, can't get hot enough without vacuum. Well you can, but the THC is smoking by then.
