Try starting out around 325-340 degrees F first, and that should get you pretty far..I've read that around 385 is pretty much the hottest temp you will need, but you will have to experiment with your particular vaporizer. Have you already bought one? What model did you get?
Also, I have to agree that it is awesome to vaporize without people knowing..I vaporize in my dorm room and my bedroom at my parents' house without any fear of being caught because even if someone walks in a few minutes after I vape, they won't smell anything suspicious
