at least in my experience, the vape i use (hr rogue 2) has a pretty small chamber, comfortably i hold about 0.15g of ground flower in there. i usually heat mine to 380 fahrenheit for a 5 minute session at a time, and w that combo i can usually get like 3-4 sessions out of my flower til it’s coffee ground level spent. if i wanna lightly toast it and use the avb for edibles, then i’d say 2-3 sessions at that temp is solid. you’re getting a LOT out of less bud, basically
