Don't worry, efrain. Just monitor your temps and understand that a fluctuation is gonna happen. When temp creeps up, close off the vent in your fire-box or charcoal box. When temp drops down, open up these same vents and add fuel (wood or charcoal as needed. A couple of chunks at a time). Always keep your chimney exhaust open all the way to avoid nasty creosote taste on your food and to ensure a good air-draw through your unit. Happy smoking!
