I'm really liking these tanks, after using Iclears. It's a bit airy for me though. Would it be a sin to keep one of the vent holes covered, while vaping?
sure give it a try, if it effects the performance of the tank just stop
I use blue painters tape, cut to perfect size (cover one or even two holes)
some I have a toothpick broke off in a hole (another toothpick to remove)
some tanks, just to temp boost performance, I just hold my finger over
a hole or two and suck to flood wick... (watch bubbles rise)
experiment away, don't be scared
(
can always return to normal)
