W/ all the pieces finally collected… I forecast large cumulus with a chance of lightning 🌩 We are havin’ a day!
@RedskinnedRhino I finally did it! I have been quietly working on a THC vape juice method to end all vape juice methods (so to speak) for a loooong time.
This was filtered just once and has been sitting 24hrs cooling. No separation and not a spec of plant material settling on the bottom.
It is pure polypropylene glycol (PG), one of the two primary ingredients in your classic store bought nicotine or cbd vape juice. The key has been temps and times as using this ingredient as the sole solvent with which to extract the cannabinoids is hit and miss.
Best part is, this, roughly 50ml, is a concentrate suitable as a 10-20% solution, and was made with only 8 grams of dried Runts bud! So the final result is minimum 250ml vape sauce coaxed from just 8 grams of grade A buds.
After creating the concentrate I add a mix of ‘base’ - which is more pure PG mixed with pure Vegetable Glycerin (VG) - the mix rate of the base can be personalized for actual consumption. So only two products are used, PG and VG (plus decarb’d buds) for the whole thing. My issue was finding the way to get the PG to extract this efficiently.
I will write up a tek, because anyone can do this and special equip is not needed. The key is using pure PG to extract and doing it at 90 deg c (190-200 deg F) in under 1 hour. I believe I’ve got a 90+% extraction here.
My decarb was a standard 250f for 40 min., and I made sure not to grind the material but instead just cut it up a little, trying to not create more teeny bits of plant matter than necc.
A slow cooker with temp control or a slow cooker and a thermostat will get it done. A double boiler also. Just keep the temp at 190-200f and only extract for 30-60minutes. I strain with tea strainer and paper towel, just let it strain, no squeezing, nothing just walk away to let strain.
It appears to me quite clear that it is not going to gum up any tank or vape cartridge, or dripper because of the high percentage cannabinoids extracted using propylene glycol alone. The high concentrate value means it vapes like a typical high quality nic vape, that and (omigawd) only 8 grams for enough, all day, everyday, chronic to vape for weeks and weeks, or more!?! Whoo-boy.
People, your lungs will thank you! No more burning or carcinogens, and it is very, very covert. This stuff is on point… finally!
