I Just made a batch Yesterday.
I use an instant pot,70-80 ml of PG and 7 grams of cannabis trims and flowers mixed.
I put everything in my Mason jar into instant pot,let 40 minutes on High pressure (about 200-220 F) to decarboxylate.
After It Is decarbed,I put the propilene in the Mason jar and Slow Cook 30 minutes in the instant pot.
When finished,strain the mixture and wait to Cool down.Here you Just obtained an infused THC flavour that you can mix in a base of PG and VG for vaping in Electric vape mods and atomizers.
@LionsNaughtyBeans feel free to Ask if something Is not clear
On the left the vape juice mixed with 20% of the concentrate,on the right side,the extracted juice
Also,I forgot to Say,I made One batch months ago and came so nice that a friend of mine Who used to smoke cannabis before than me said he would pay for a bit.I did It without an instant pot,It Is 100% doable
