Hi everyone. I just bought an Arizer V-Tower Vaporizer. This is my first time vaping so this is a noobie question. So I ground up the herb and put in the glass bowl and stamped it down so it's compact. I heard you don't want it too loose or it doesn't vaporize as good. I turned it up to 190 degrees Celsius and waited a minute for it to heat up. Then I started to inhale through the whip but was getting basically no vapor. I tried sucking harder by this caused all the weed to rise up in the bowl and scatter towards the top and I again got very little/no vapor. To be honest a few times I got a little vapor and I noticed that the weed had turned brown, which I heard means it vaporized the weed and I did get a small buzz. But later I didn't get it brown anymore. I used maybe 2 - 3 grams of weed, is that enough or does it matter how much you put in? I know your not going to get as much smoke as if you use a bong, but you are supposed to see a fair amount of vapor, right? I even turned it up to 250 degrees celcius to make sure I vaporized it and still virtually nothing. It's a digital vaporizer that shows the temperature, so I assume there's nothing wrong with the heating element. Does anyone know what I'm doing wrong? Thanks.
