I have a question for the E-Cigarette veterans on this forum. I have been vaping for the past 2 years now. The one problem that I always had was lack of vapor production. Right now I am using Vision Spinner batteries with the Kanger Protank Mini 3 with the Aerotank Mini Airflow Control Valve. I started doing lung hits because when ever I tried to do a mouth to lung hits I don't get good vapor production. What am I doing wrong with my vaping techniques. I even added vegetable glycerin to my e-liquids to thicken them. I made my e-liquids a 50/50 mix. Don't get me wrong, I enjoy the lung hits because of the vapor production.
