he's right about that the fact that you have to vape at least between 365-378 farenheit to get all the levels of thc in the plant matter. If you're vaping below 365, it's not a waste exactly because it is much smoother at lower temps but you're not getting the full high out of the buds. Some people think you can just turn on your volcano and get the same results at any temp but that is entirely false.....different temps for different effects. I like to vape at lower temps in the morning, slightly higher temps after work and the highest temps for sleep or when I want to get the highest possible, but that's just me.
