Re: how to make shisha wetter?
If you're going to stick with QL's my suggestion is to use Holland QL's. They've never done me wrong when I run out of CoCoNara's. And have you tried using a windcover when only using one coal?
Right now, I'm smoking out of a little 10" genie myself with a HH genie vortex and I have one layer of heavy duty foil (shiny side down) with my personal hole pattern, one coal on a quater of the bowl and using a windcover. I leave the windcover on the whole time and it smokes just like my 24" syrian.
