I guess my question on this subject is a simple one....."How Much?"....I get home around 4pm. Take care of some things and usually have a fire going by 5pm. I hit the hay around 9 or so...(4:15am comes early!)..How much should I stuff the stove with to wake up to a bed of coals? 50% or more of the stove's capacity? That Jotul F600 can hold alot. Thoughts please.....
