I know someone who has a Volcano and he's an expert at it. Once the control light goes off and you heat your Volcano up, grind up some nice green bud. Fresh is best. He heats it up to 5 first, then 7, then 9. We did not even 2 cycles of that and we got ripped out of our minds! He's giving me his Volcano for about $75 cheaper than what they sell for on the market. He's only used it about 8 times.
