What is Vegetable Glycerin?(VG)
VG stands for Vegetable Glycerin. It is a natural chemical, derived from vegetable oil. It is commonly used in e-liquid to give a dense vapor. The hit from a high VG fluid is a lot smoother than with PG, making it more suitable for sub-ohm vaping.
The increased thickness of VG means it can reduce the life of atomisers quicker than PG-based juice. High VG liquids clog up coils more rapidly, and will not work well, if at all, in certain tanks. Older products are especially susceptible, particularly models that use smaller coils such as clearomizers, eVod's, Protank 2-3, Nautilus Tanks, iclear tanks, and T4 tanks are some of the more well-known tanks that are known to have difficulties dealing with high VG fluid.
