Re: Stupid question on proper windcover usage!!
With me, it honestly depends on the setup I have at the time. With my 11" Havana pumpkin hookah, I have a small mod bowl and use one Holland QL and leave the windcover on the whole time. This way I only need one coal on a quarter of the bowl to smoke a full 45min session and I can always remove the coal when it goes out and add a new coal to the next bowl quater. GIving me 4, 45min sessions.
With my 22in mod with a vortex though, I pretty much just use it as part of my heat management. I set up with 3 coconaras and place the cover on to get it started.
It's all personal prefference, just play around with it until you like it.
