Yes. Adding more VG, by way of VG flavors, will increase the VG ratio of your mix (and vice versa with PG).
PG stands for “propylene glycol” and VG stands for “vegetable glycerin”. PG and VG are liquid ingredients used in vape juice, which can be combined with differing levels of nicotine. These two ingredients are combined in various ways on e-juices to suit each vape user's preferences.
Propylene Glycol is a colorless and odorless petroleum byproduct. This ingredient gives what vapers call a “throat hit” on the inhale. A throat hit is said by users to mimic the sensation when smoking tobacco products. So tobacco lovers usually gravitate to e-liquids that contain a higher PG. Additionally, PG e-liquid is the less viscous option of the two, which makes it more easily absorbed by cotton fabric inside cartomizers and wick tanks. Other differences in PG compared to VG are:
- Flavorless: PG has no taste and no odor, so it doesn’t alter the flavor of the vape juice in anyway.
- Less build-up: Since PG is runny in consistency, it builds up less gunk on the heating element of vaporizer on your device. The liquid is easier to clean off your vaping device than vegetable glycerin.
- Throat hit: The throat hit is stronger with PG, which is considered to be similar to tobacco cigarettes.
VG on the other hand is different. Vegetable Glycerin is a natural substance that is taken from vegetable oil. Because of this it’s considered to be a natural chemical. VG is thicker in substance, which causes thick cloud production on the exhale. When e-juices are described as “smooth,” it is because of the VG that is present. The differences in VG compared to PG ultimately are:
- Flavor: Vegetable glycerin alters e-liquid flavors and causes them to be sweeter in taste.
- More build-up: The thick viscosity of VG causes for more build up. More cleaning is involved or else your vaporizer becomes in danger of getting clogged.
- Throat hit: The throat hit is significantly less than that with PG, which makes e-juices smoother on the throat.
Some folks are intolerant to PG and prefer VG when mixing.
