After testing several RTA styles over the past few months, I noticed that light condensation sometimes builds up around the airflow or under the tank, even when everything seems assembled just right. From what I’ve seen during our in-house testing and daily use, this usually comes from slightly overpacked cotton that traps vapor, overfilled tanks with no space for pressure balance, or just temperature differences between the coil and the tank body.
A few small habits have helped me reduce it: leave a tiny air gap when refilling instead of filling to the brim, keep the cotton tails loose in the juice channels, and give the coil a short warm-up before final assembly to settle the wick. These small tweaks aren’t magic fixes, but together they make the setup cleaner and more stable—especially for tight MTL builds.
Curious if anyone else has run into this and found other tricks that work for them? Always happy to learn from your experiences.
