I have seen that in most computers liquid is present and a box for the percentage of water (distilled, I understand). On the basis VG Inawera I saw also a percentage of water present. I know that VG is thick, it is also likely that streamlines. Or maybe somehow influences and flavor / TH / vapor amount?
I try to produce a PG-VG, mostly PG, PG Inawera base and pure glycerin at the pharmacy. What recommendations do you have for a beginner, as a starting point, as% water to put?
