Welcome to FC, Weirdscience.
I'm afraid that you've posted this in the wrong forum. The Vapor Lounge is for anything not specifically relating to vapourisers, vapourisation, or cooking weed. It would belong in the
General Vaporisation Discussion forum, that is, if your questions had not been covered many times before, over and over. In fact, this thread may well get tossed by a moderator into ABV (the archive for dead threads).
The mods like to run a tight ship here at FC, which includes minimising duplication of topics, and listing them in their appropriate forums. It keeps the place in some sort of order, making it easier for people to find what they're looking for, and making discussions more comprehensive and useful. So I suggest you do a bit more reading, and use the 'Search' function. You'll find answers to your questions easily enough.
But to kick you off
here is a good thread for you with regard to vaping temperatures. Ideal temperature to vape at is a matter of opinion, and many people don't have an ideal temp - it depends on the strain and quality of your weed, and what effect you're after. And by the way, digital readouts on vapes are notoriously inaccurate - the easiest way to judge how cooked your weed is by checking the colour of it - if it's still green, you've gone for a lower temperture, but if it's medium to dark brown then then you're vaping at high temperature. Just don't take it to black.
