Whenever I use the Vapor Bros I usually start it out around 1 oclock and end up turning it down to around 12 oclock after about 10 minutes.

Yea, we fill it up 1/3-1/2 the way up then usually tamp it down with the back of a pen or something just to compress it the TINIEST bit.

A bowl that size will usually give 6-8 good hits (15-20 seconds). After the first three take a paper clip (bent so it's straight) and stir the weed to expose stuff that wasn't exposed earlier.

Hope that helps.
