PG
VG
PDO
Terpenes
^^ I used all of these and settled on a majority of a terpene mix, added to as much extra PDO as needed to get to desired flowability. I add the terpene mix first as I slowly raise temp then top off with any additional pdo.
Terpene mix:
1 drop limonene
1 drop a- pinene
1 drop β-Caryophyllene
Its been a minute since I've reordered but I think they have entire strain profiles now, so you should just be able to buy your favourite strains terpene mix and thin your concentrate to desired flowability. The terpenes are strong, so you'll probably have to dilute them with some other chemical, but the less chemical (pg, pdo) the better imo. VG didn't mix well without PG, or it was the other way around lol either way PDO seemed smoother to me. I use C-Cells and a pretty thick concentrate, the ccell does pretty good with the thicker stuff but the more chemical over terpene mix that I use the darker the oil will get.
