Whats the main differences and where can I buy them? Can you buy PG or VG by itself or is it just glycerin by itself? I kinda know the differences between VG and PG and how they are both glycerin but if I'm cutting it then will I just get glycerin? I'm getting a tad bit confused . . .











Any help would be great, even links to other threads. Thanks.
