The popcorn taste you are complaining about is because you are getting the weed too hot. I used a digital hotplate, but the surface area wasn't getting enough circulation. Maybe you could use a large metal screen. Put the screen inside the light bulb so your weed isn't directly touching the glass, and wind from the tube can circulate around it better. I prefer a joint, but would love to find an inexpensive efficient vaporizer. Any suggestions?
