im new to this, just built a block smoker, used it the first time over the weekend, as of now im using charcoal to fire it with, and hickory wood for the smoke, my question is is there a better source for heat? flavor? and i also went thru 4 , 15lbs bags of charcoal to keep it at 225. my smoker is just a rough edition of what it will be, but wanted to figure out any improvements before i make it permanent. so is this a normal amount to charcoal or is my smoker very ineffecient? also is there any advantage to having it horizontal vs vertical. i know verticle would be more efficient. thanks , montyg
