Sorry guys I have to most stupid question to ask lol

[piggypinggy]

what does "tighten up" the airflow mean? Does that mean making the hole bigger or smaller?
Because I was watching a video, it says while I use thick juice like 70% or 100% VG, I should tighten up the airflow, what does that mean?
Sorry I'm new to e-cig and English isn't my fist language, thanks for the help!

PS: I'm using aerotank mega

tighten up = less air flow. so... smaller holes. you got it.

..smaller hole with thick VG juice, so that you make more vacuum in the tank, that can suck the juice into the coil.
