Hint of advice. Know, not assume, what you are Vaping.
At least 70vg might be 90vg............if you don't know.
A Few fun facts about VG.
Not all VG is the same. Aquios VG is a thinned VG(distilled water added) which flows and wicks better. Pure Vg is like syrup so the higher the content the thicker the mix.
VG is highly effected by Temperature. In a Cool Room, a Cool Tank may not wick right away. Short Vapes - Recognizing dry/hot vape, will save a coil and get the tank warmed to proper function.
*Max VG and High VG mixes that are NOT Aquios VG may not work well in Many Coil Head Tanks due to slow transfer.
Most Vendors do not indicate which form of VG they are using.
Save money, replace your liquid......................and always Prime your coil heads.
