If you inhale as if you are sipping air through a cocktail straw, so that it takes a while to fill your lungs, you may find that you'll get a large volume of vapor.breakfastchef said:In my limited experience with the iolote, it does not produce voluminous vapor as one would expect from a hookah. I think this device is a compromise between vaporizing and portability. It works well, but does not work phenomenally well.
Sometimes folks draw too quickly. That will cool down the chamber and it will cease vapor production.
In addition, the dryness of the herb (dry) , and size of the grind (small) contribute to vapor hit size.
