I am trying my luck at curing and smoking a picnic ham. I cured it and have it in masterbuilt smoker now cold-smoking for 12 hrs. It will be ready for me to hot-smoke around 12 tonight. I will up the temp but don't know how I will keep it smoking as it burns chips pretty fast and I can't stay up. So it will cook without smoke for few hrs til I get up. Do you think that would be alright? Also don't know how much I should leave vent open.
