congrats...you can use it w/o a water piece(I run it on 3 or 4) but it's far more effective through glass(running it on 5-6 depending on glass volume). be sure to get the adapter I suggested from Planetvape when using glass -- very well made, short path, good sized bowl, good draw. as mentioned, I get HUGE clouds through my Moby Nano using this adapter. any questions at all, please don't hesitate to ask. cheers!
