most important things to remember when doing oil extractions with weed ;
1) you DONT NEED high quality stuff, its actually a waste.
2) patience *WILL* make the difference between a weak or potent finished product.
take an oz of Shake, if u cant get shake, get an oz of the cheapest stuff u can, if $'s not a problem, use an oz of outdoor, its way better than indoor mids or regs b/c its got more trichoms, n thats what youre after. Get a long metel or steel Pipe thats hollow and open on both ends, its gotta be at least 3" wide, n thats the hole alone. Basically its easy from here, you grind the shit out of your bud til its POWDER if u can, put it in the pipe, and pour 99.9 iso into it JUST until it fills up to the same level as the bud, seal the other end of the pipe, and shake around for a few minutes then leave it over night, shake it again/leave it and repeat, shake every 8-12 hrs, and by shake i mean more just move it around, you want the oil to suck out all of the goodness in the bud matter(trichomes, oils, etc), wait at LEAST 4days, you can wait up to 10days, this will give you a better finished product. Now when youre ready, open 1 of the ends and pour it all out directly into a fine, but obviously not TOO Fine strainer, fine enuf that no huge plant matter is gonna get thru, but not too fine that its not even straining. Leave it n let it do its thing, wen its no longer dripping, move the plant matter around wit a spoon or w/e, press it, basically u wanna get ALL that last bit of juice out of the bud. Now the buds useless, trash that.
Now, youve got your Oil, you need to Evaporate the ISO out of it, leaving you with a very nice thick oil.
You want to pour it out into a PYREX* dish, youre going to want the level of oil to be as thin as possible, obviously so it dehydrates quicker, now u just wait... after a good 38-48 hrs, come back with a razor and start scraping youre extremely potent product.
ORRRR, you cook it off on the stove, this will leave you with an even more potent product, you basically put the oil in a ban on a stove top set to the LOWEST SETTING of heat you have, ITS EXTREMELY DANGEROUS IF YOURE AN IDIOT, when ISO catches flame, the flames Clear, if you have ne on your clothes/arms hands, you wont know your burning/caught on fire til your skins falling off.. SO VERY LOW HEAT, stay with it at the stove, itll take 20+mins, like ketamine, the slower slower, the better and more product youll endup with.
obviously do alot more research.
Good luck
