FINALLY got my rig up and going lol, but I just cant seem to get my rig to blow big clouds. Rocking a Sigelei 150w + Horizon Tech Artic Tank with 2 Sony 18650 2100 mAh batteries. I started at 20W with the air holes half open and I got mild clouds. After some rips I turned it up to 30 W with full air holes and it only got worse. The screen reads it at 2.2 V atm. What should I use for airhole to watt that won't make it too hot but will chuck clouds?
