Extraction VG vs PG for extraction

This video comes from Ardent Cannabis, maker of the Ardent Lift decarboxylator, my favorite MJ appliance.
Bottom line: Vegetable Glycerin is terrible, Propylene Glycol is excellent.

Thanks for this. Mom just got her MM card and can't smoke/vape, and I didn't want her wasting any in budder. Dunno what efficiency it has compared with ethanol but for her it'd be simple/manageable. Wanted her taking sublingually if possible.

Vegetable glycerin is notorious for being a poor dissolver of cannabinoids, and I'd avoid it.

I believe the most versatile product is oil tincture.
It can be used sublingually without burning, put into capsules, or cooked into almost anything.
There are at least two distinct ways of making it.

The least efficient method is to soak the herb in oil, strain out the herb, and then use more heat to infuse with oil.
Unfortunately, this can be inefficient, something like 30-80% depending on method.
There might also be an upper limit on how much medicine oil can absorb from herb, when considering convenient concentrations.

Grinding the herb to powder and not straining incorporates 100% of the medicine, but sublingual is icky.
Baking and putting into capsules still works well.

Slightly less efficient than using whole herb, but more efficient than strained oils is to make FECO (Full Extract Cannabis Oil) and dilute it with any oil.
The FECO can be mixed with any amount of oil, so caps can be made very concentrated, and fewer would need to be swallowed.

Whatever you do, be sure to decarb first (240 F for 40 min).
Lecithin is also used by most people.

Thanks for this, I thought making a PG canna vape juice would be more difficult.

Can you guys give me a recipe(ml of PG and vg and Grams) for a good CBD vape with my Buddha medikit auto weed I dried?
I have to use the jar in boiling water decarb and since I have only 8 grams,I don't want to waste my last weed.Percentage of CBD it's 20 max on this strain.
