Should the color of the Cannabis determine when to remove from a Digitial Vaporizer

[MindDoctor]

Your vape bowl is plexiglas? And it's "top of the line"? :wtf:

You shouldn't be getting black remains at 386 F. If you are, then your display isn't accurate. Your bowl is done, at a particular temp, when you get no more visible vapor (best seen under good, direct lighting). The burnt popcorn taste is also a sign.

My plexiglass does not get stains or turn black at 386 F. I only wanted to know about how dark should I let the color of the cannabis get, before I renew. (I enjoy the taste best at 386 F). I continue to use the same cannabis until the vapor become on the bitter side, then I grind up new.

As for my plexglass, I do not get any stains or black remains. After four or five changes weed, I use a "1Mnute Formula 420 Prex-Glass-metal-Ceramic", well shaken and mixed 50/50 with water and sterilize the plexiglass, using a cotton Q-tip just for the hell of it.

Thanks for taking the time to reply.

Best regards,
