The amount of VG and PG in your e-liquid will add up to 100%. So, if your e-liquid contains 50% VG it will also contain 50% PG – often referred to as 50/50 e-liquid. This is the same for any amount; a 70% VG e-liquid will contain 30% PG (70/30 e-liquid) and a 40% PG e-liquid will contain 60% VG.
The VG/PG ratio you need to select will depend on what type of kit you′re using. We always tell you on the product page what the best VG/PG ratio is for any kit.
