THC extraction

[harmonicminor]

everclear is the highest sold I know of
but you can make it with a still also

i've heard the same.. and that runs at 90% alcohol... they also sell 90% rubbing alcohol.. so back to my question.. does it really matter if i use drinking alcohol over rubbing or vice versa??

just get pharm grade iso alcohol from the drug store. thats some the cleanest you can get over the counter. then as longs as you arent drinking it and you evaporate it all the way you are safe.
heres a little evaporation trick I use that will keep you from blowing up the house or something .....
take an old coffee maker and take the top part off so you are left with the burner with the on switch. use a pyrex dish on the burner with your goodies in that. get a bathroom exaust fan at home depot with some exaust tubing. place the fan above or by your dish and run the exaust out the window.
takes about 3 hours start to finish this way and you wont be breathing the fumes or burning the house down

I have also built one that was totally contained in a bucket that I used for Salvia extractions with Acetone. this one I cut 2 holes in the lid for some 2 1/2" pvc pieces to fit in and hooked the exaust tubing to one but had the fan on the inlet side so there was no risk of spark from the electric motor setting off any built up Acetone or fumes.

wat happens if u use acetone to extract??

[harmonicminor]

I usually use it for Salvia but I hear it works for mj too and that it is more selective in what it pulls out " no oils or fats". It will evaporate a lot faster than alcohol but you have to make sure it is all gone and there is no acetone smell either. also you should evaporate an amount in a dish to see if it leaves residue. If it does dont use it.
but to tell you the truth I have great results with iso alcohol and when it is almost evaporated I put in a small amount of powdered weed to soak in the oils. makes it like commercial hash but fresher and you know what is in it. I hear some commercial hash made in other countries contains and amount of banana peels and camel dung for wieght. yuck fuck that I'll make my own thank you

Iso oil strips the glands from all the vegetative material (bud..leaf..small stem) but it also strips waxes, chlorophyl and other things from your pot..thus the green colour and the fact that it smokes like roofing tar and tastes like ass...
I make butane honey oil on a monthly basis..and I plan to make a few vials in a couple of weeks..I'll bring the camera along..
We had some tested by Advanced nutrients (for med use) and it was 75%THC..
Generally..even with the worst pot I can scrape up..it still comes out potent enough for 2 drops on a cigarette to give you a good hum...

[harmonicminor]

If you do a fast and cold extraction with iso alcohol on nice crystally buds you can get nice golden oil that smoke just as nice as the butane method. a little safer and cheaper but takes a lot longer

Petroleum ether. Much better for extraction, but, from where I am, much harder to get ahold of, cause it's on the list of "banned" chemicals [obviously used for meth production].

did I say synth???
no I was talking about natural isomerization with acids
