About a year ago a buddy of mine bought himself a hookah, and a quater of some nice diesel kush. I met up with him, then we loaded the bowl completely. It was like a 2 gram bowl, and got the coal nice and red and laid it on top of the bowl. After the first couple of tokes I was completely ripped. It took about 10 to 15 mins to finish that bowl too. So it definetly works wonders if you have large amounts of bud.
