For those who are inclined to mod: I recently placed a couple o rings on the volcano bowl which allows for a tight seal with a hydratube.
I've tried this before with cold water but this time I used boiling water from the kettle to try and hydrate the air, as I've been thinking the volcano produces more dry air than other vapes due to its design.
The result was the smoothest vapor I've experienced so far from the volcano, and even allowed me to raise the temperature past 6!
It's worth mentioning that I've hooked my volcano bags up to a bubbler with hot water before and did not get the same smooth vapor. I think it has to do with immediately hydrating the vapor vs waiting until you inhale through a bubbler.
In my experience it works best with minimal inhalation and allows your lungs to fill up like a balloon with the barest minimum of effort. I find myself wanting to use my volcano like this more and more lately!
