I hope it's not bad manners to post on an old thread, but I didn't want to leave readers with the wrong impression about Da Buddha. After some logging and keeping track, I concluded that I use the same amount with both. For some reason, I'm using more than I used before, but that's a separate issue. And having paid more attention to both the DBV (Da Buddha) and the VG (Vapor Genie), here's some info that some may find helpful.

One thing I noticed is that the DBV produces lots of visible vapor easily and reliably while the VG doesn't. However, this made no difference in the actual effect. I think the explanation is that the visible part of vapor is largely steam (water), and for some reason, the DBV's operation facilitates the formation of steam while the VG's operation doesn't.

Maybe the reason is that the VG's method of using a hand-held BIC lighter is inherently less precise that the DBV's control knob, and steam doesn't form as easily when using a BIC. Or maybe the short wooden stem of the VG discourages steam from forming.

Whatever it is, the effect is the same. Whether it's carried in H20 or plain air, it's the same THC. I felt it just the same either way.

Anyway, I still haven't ordered the Purple Dayz. I'm going to use the DBV and VG I have a few more months before deciding where to go. They're both very, very good vaporizers.
