I bought a Lotus Vaporizer about a month ago and I've been burning herb with it ever since I started using it. It starts to smell like smoke, it burns my throat, and then I exhale a big cloud of smoke. Look inside and the bowl is completely ash. Kinda defeats the purpose of a vaporizer since I bought it mainly for health concerns, but also so I can smoke inside / in my car without any odor. I've contacted Lotus Vaporizer support to see if they have anything to tell me. The two herbs I have used it for so far are damiana leaf and catnip. I've also used marijuana with it, but that's before I knew how to properly work it... When I used weed the weed was still green after several attempts at vaporizing it. Then I figured out how to use it properly when practicing with the two cheap herbs (poor college student; can't waste weed learning how to use the thing). Anybody else own a Lotus and ever have this problem? I'm getting some more marijuana tomorrow to make sure that doesn't burn too. I know all herbs have different vaporizing temps, but the Lotus is advertised as some kind of universal one. There's not really a way to adjust the temperature on it.
