Is there any specific type of alcohol to look for? My lady is a hair stylist and can get 99% from the hair supply store. I always did bho in the past but now that I'm using a trim machine I need to try a new method. So I appreciate the advice!
I use Swan 99% ISO I get on Amazon.
Any 99%ISO 1% water will work great.
Someone sooner or later is going to say isopropyl is bad and to use PGA (pure grain alcohol)
I have done extracts with 99% ISO and 95% Everclear.
There is NO COMPARISON between the two.
With Everclear my yield is only 12-14.5%
With 99% ISO my average yield us 17.2-24.5%
A few weeks ago i picked into 26 grams Northern Lights too Dry to smoke. I picked them up for a song.
Now Northern Lights is only 17% THC abd 3.5% CBD (one of my favorite strains for Crohns disease i call the family curse. Even with dry buds i extracted 4.4 grams of concentrate or 16.9%
Another positive side of using ISO instead of Everclear is the appearance of the hash oil.
ISO it is a honey/ amber color.
Everclear the Hash oil is brown or worse.
Extracts made with alcohol tends to be harsh to smoke because of the clorophyll fats and solids. So as soon as i strain the herb from alcohol i put the liquid back in the freezer to winterize for 6-12 hours then still in the freezer filter the liquid inside the freezer..
When properly winterized i woukd rather vape an alcohol extract than BHO. A few people have started winterizing BHO.
I evaporate off the alcohol by sitting the alcohol near a window with a fan blowing the fumes out a window.
When most alcohol is gone i put it on low heat like 120-130.
Too much heat will destroy the quality of the vape.
There is a thread here i think it is called ISO slab NO butane or similar. If memory serves i think i posted two or three of my extracts there.
