Struggling about vaping correctly

I have been vaping with my ‘Vaporizer Nebel’ by vapeble and I have some questions; it has a 5 minute timer on it and do I need to inhale as much as possible to get more highs or is it better to take maybe 10-20 second breaks between each hits? I experiment with the temperature around 200-210 degrees (sometimes I go higher), and when I go higher with the temperature, at the end of the session it becomes brown/blackish rather than golden brown, is it something I should avoid? And I saw that people use the vaped weed to make edibles, is it something that you would suggest?

Really happy that I found this community, thanks in advance!!!
