I think I just made a huge discovery for users of this style of vape, but I haven't read through the PD threads to see if anyone else came up with it.
I was cleaning some glass I use for combusting and when I was done, I had a little bit of ground up bud left on my grinder and I decided to just pack a small bowl into my little one hitter and toke it up. Then I was looking at the bowl thinking, "what a waste." I glanced over at the topo zap and, for some odd reason, decided to see how the one hitter fit on there and much to my surprise, it seemed to make a nice seal over the outside of the heat port. I couldn't tell if I was getting anything when inhaling, but then started to feel it - huge vapor!! Very clean taste. Everyone has got to try this!

Since there is so much more herb in the bowl, the hits are just ridiculous.
Be careful not to damage anything though. I was gentle. That black thing is the ash catcher. Guess I don't need
that anymore.
