Ok, between vaping and downright smoking, there is a range of temperatures. At a low temperature, you may be getting pure vapor but not all the THC; at higher temperatures, you may be getting all the THC but also a few chemical precursors to combustion and smoke. So you need to experiment and learn by touch, so to speak.

On my vaporizers, I like to get the herb as brown as I can before giving up on it.
THC vaporizes in the lower temp range (375 is supposed to get it done), but most people go a little higher. Most also want the other cannabinoids, and most of them can be had at around 400 F.
