I can't get my head around this. I have 60vg/40pg pre-mix and I'd like to get to 80vg/20pg so if I took 100mls of it, how much extra vg would I add to make that 80/20?
You need a calculator. Flavor will affect your pg ratio. You can get the ratio back in line using something like this https://ecigvape.com/e-liquid-combining-calculator
Hi. Just a suggestion, in the future, I would buy VG/PG and nic separately. That way, you can mix it a whatever ratio you‘d like. Stay safe.
Lets look at the (not a math person) math (even though you've found the answer).
100ml of 60/40.
=
60ml vg
40ml pg
well let's just start adding to the vg to make it right?
- 60 = 120/40 = 60/20. Closer
- 80 = 140/40 = 70/20. ok, getting the system
- 120 = 180/40 = 90/20. Fuck
- 100 = 160/40 = 80/20.
so with the most basic of math (which is about my peak ability) we've got 100ml added to get you your ratio.
same idea with flavors, but a whole tonne more guessing.
