Been working on a project to turn one of them "cloud chasing" ecig mods into a dry herb vape. Having a few minor set backs, looking to see if anyone has done this bfore. Finding a proper screen element amd keeping the mod cool enough to hold are my problems so far. But my goal with this is to be standing next to someone vaping eliquid and be able to hit mine and no one be able to tell. But, it must vape and not burn (otherwise the smell would b a dead give away), and it's needs to hit better and more than my ego w dry herb tank. Ideas???
