I drilled a 1mm hole in my Subtank Nano where the airflow was in the closed position. I can not believe I have only done this now.....Now I have one device for both styles of inhaling and hardly use my Nauti mini anymore, I used the Nauti only for mouth to lung, which the Nauti was great for.
The draw on the Nano is perfect for mouth to lung with a 1mm hole. The standard smallest hole on the Nano is way to airy for this.
