i dry mine thoroughly just to infuse the middle of the herbs (as the outside dries, the moisture moves inwards, saturated with the goodies), then i rehydrate.
i like it pretty wet, actually. i keep a small personal stash of hydrated changa, and the stored "big daddy" stash i keep as dry as possible.
with vaporizing, it seems that a bit of water helps thicken the vapor, and afaik all that water vapor has at least a fair amount of goodies in it.
ofc, when its pretty damp it helps to have a small dry piece of white sage or caapi leaf on bottom to act as a screen.
