Hello all. I'm sitting here with my first little mod vaping some delicious SPACE JAM ',PLUTO' flavor (it's soooi yummy) . I've been vaping for about a week, pretty much quit stanky stix, (had one yesterday and one today but they were pretty gross and i know I'm done with analogs) ... So to get to the point I have a very basic question that i need answered by you fine folks. What does PG VG mean? I know it's measured in juices by percentage, but thats about all i know. I would so appreciate a thorough explanation of this if possible. Thanks so much. I love ECF!!
