i dont know if you have the new volcano with the digital screen but on the old one with the analog dial on the front i put a teaspoons worth in and i set the dial to 5.5 and smoke untill i feel high then i put it away for whenever i feel like smoking again i re grind the bud in my grinder so its finer and mixes it up then i pour it back in the chamber set the volcano to 7 and i smoke increasing the knob by one every 2 bags untill it hits 9 and im high then i throw away the leftovers
