Went to vape shop and purchased when I went home the label said 60:40 when I asked for 40% PG and 60% VG. I was confused so I called the shop back, and I was like, usually it is PG:VG, I ordered 40% PG and 60% VG so why does it say 40:60 (PG:VG) ? He said that some shops did it that way (backwards {VG
G}). has anyone ever heard of this lol? PG:VG...vs...VG
G? Isn't that like L x W haha or am I mistaken?
