well i use a lightbulb vape (ghetto and shitty sounding, i know) but i heat the herb up enough to where u can see a nice mist and when u take your hit you can feel a little bit of harshness. U dont wanna see full smoke because then you are just smoking weed, not vaporizing it. When u exhale you should see vapor that looks like a very very very weak pipe hit. I love my ghetto ass lightbulb vape. Happy vapin and any more questions just post
