Re: ******* HOOKAH CHARCOAL!!! (Naturals)
when I'm really stressed out, like right now, i go through a cube in 7 minutes flat due to the rapid long deep drags.
but seriously, they can last from 30-50 minutes depending on the batch, how long they've been exposed to air/moisture/humidity. but still 30 minutes is good. i remember using bulk coal before cubes and it seemed like i was adding coal every 10-15, turning flipping etc.
