Another wise word: put an extra screen over the bowl, below the elbow joint. This screen will collect all sorts of resin and green and what have you. Later you can use this screen on its own in a bowl, turn up the heat and let the good times roll.
Completely missed the post above, man im gone. I never fully agreed with huge clouds that you exhale instantly either, it always used to be a ghost every hit game for me. But if you can get away with very little herb then it is pretty funny. Blow up a really dense bag for example using some technique then take small, manageable breaths and get wicked stoned. I dunno man, I posted loads of theory somewhere or another.
Tanagble quantities i can give. My mind is oddly active and is making me post variations on an idea in various locations. Here is a main result to begin:
http://www.youtube.com/watch?v=lf5DVsOQZRo this density was given at 190, fan speed 1 and was enough to nearly fill a bag. Not to burst mind. The bags were generalyl giving 3+ big hits, and these hits could get
too big.
I used this much normally, in one way or another
with a canadian quarter for reference. and secretly because i feel proud being here. haha that particular load was a night cap, fluke 10 hits i think, added a bit and got a few more. Its all documented on a toothbrush i have lying in the area, 15 tally marks and a big K.O. What a tangent, imagine that much used but in crushed bud to get a feel for your regular bowl.
I can also offer thoughts with regard to heat to vapour thickness. You are right. However, this technique (and in a much more professional way the herboorizer and vriptech wand) work by heating through all the herb in a short time. I don't own a wand, but im guessing from videos. In my technique, also there is no need to stir the bowl and when it comes out the herbs are totally spent. Combustion does not occur (sub 225 degrees ish), so we cannot worry about excess heat. When the herbs ae done, they are done and just stop producing vapour.
I hope this post is going some way to answer your queries.
