i always use 99% rubbing alcohol, and always evaporate it off by weight. when I make an edible liquid needing to be thinner I use 199 proof, uh, stuff.
I saw somewhere that one of those table top water distillers, with a simple change out of the thermostat, will distill a store bought box of wine into it's clearest purest,..value, just sayin. I use 70% rubbing to for clean up only(too much water to contend with later)
the straight oils are put into the large glass cup on the mag mixer. its already been frozen(to seperate the wax from the oil) and then poured through a coffee filter/activated carbon pouch, then whipped a little on the stirrer, poured out in the clear glass and evap'd, by weight, on a hot plate, now curing.
I sterilized some stuff for culture time like a scalpel and large tweezers, paper towel and premixed jars of medium. next day I opened the pressure cooker and tightened the containers, divided a bunch of callus material into their own continers to start rooting. If you havent tried to grow/smoke ace of spades or plushberry yet, they may end up being your Holy Grail weeds...added to tahoe og, lemon skunk, Kandy Kush/skunk...they are for everyone I know. just a far out over the top grow pattern suited for anything. I've had 6 footers, and 3 footers too purposely. they all are one hit wonders with a perfect blend of sativa/indica with no thump, but lots of energy, and sets the barr for everyone single person that has had it, real fire genetics

crafted by the big pros. I may never bother with any other again. those 5 in my stash all the time have proven to be pure bliss for every occasion leaving me wanting for nothing, but another rip !!
peace
