And how is it to vaporize changa in the GVG? If vaporizing changa then how many screens should I put in there?
The ceramic piece wont ever be glowing, at least not that I've noticed, The GVG is the PLATNUM STANDARD for vaporizing changa. Very mellow cool smoking I hardly feel the vapor, but, wow! The breakthrough comes on a little delayed for me but it happens every time. The best part about the GVG is there is NO waste. The GVG is the most efficient delivery system, hands down. I only have 4 screens in mine and all I vape is changa. I guess you could put more in there. I hear of some people using 7 or more. I only put in, screens, what would fit snuggly.
