Just did a fresh bowl in my Volcano and started off at 417*F, produces some very thick smoke-like vapors that I can blow O's with. I am pretty vaked right now just from this one bag. I would usually do 3 bags starting off at 369*F and finishing it off at around 400*F. But I wanted to experiment this time, so I upped the ante so to speak. I can't believe how vaked I am from just this one bag at a higher temperature, gonna do a 2nd bag at 427*F (around 8.5 on the classic) and see what kind of spell it casts upon me.
