How do I make my own vape fluid

I know this seems like it should be in the vape section, but my reasoning for putting it here is that this subforum is much more knowledgeable with creating tinctures/oils/etc. I'm curious as to how to make a fluid that can be used in a refillable vape. I'm fully aware of the decarb process / oil infusion process / GD tincture process, but what I do not know is which mediums to use to create a vape fluid and which methodologies I should implement to do so. I believe vape fluid is basically just vegetable glycerine, but I could certainly be wrong. Should I infuse veg glyc directly, like creating a cannaoil? Should I be creating an alcohol tincture and do a transfer to glycerin? Any and all help would be appreciated.

 

Hmmm. I kind of, for some reason, thought glycerine was another form of oil. So I guess standard cannaoil techniques won't work (ie 240* 40min decarb, add oil 220* 20 min, freeze, then 220* 20min again).

I don't have the patience for the long method, and the "fast" method seems to be a pain in the butt. Are there solvent transfer methods that can be done? For example can a GD tincture be transferred to glycerin? If not I think the easiest solution would be to use a sous vide and follow a modification of the second technique. I think I'd rather decarb first and then sous vide at 180*. It just seems easier. But another (better?) method, maybe follow their second technique and sous vide at 180 in three rounds (like in the video), then do a "final decarb" in an accurate oven at 220 for 30 minutes like specified. Anyone have any input? @PsychedelicSam / @BrassNwood you two geniuses specifically?

Couple additional questions:
1) What's a standard or low dose concentration of THC/mL for vape juice?
2) When calculating my final concentration, what kind of percentage loss should I expect to have from original flower THC percentage?

 

Any comparisons to True Terpenes?
