this stuff can extract way too much just like ISO or ETHANOL RUNS.. .. so if people want a good extract they shuld use 3-4 different pyrexs .. and do small sprays .. and go 1-4.. and the last pyrex u allow to get dark.. ull get light color in 1 and 2.. and darker in 3 and 4.. 4 darkest if u let it spray threw for a bit.. then use 1 and 2 for smoking.. 3 and 4 for edibles or topicals.. works great..
but ill stick to BUTANE honestly.. if u wana do extracts like this.. id rather buy lab grade ether instead and do washes with a funnel.. and just allow it to drip threw while spraying the top.. and mix spray.. and still using a few pyrexs so u don't get nasty shit in ur smokeable oil..
I tell everyone.. dont skimp.. buy a chamber and pump if u wana know what your smoking.
