Any help is greatly appreciated.
Not as effective but not a problem here is the answer to your problems.
A lot of people on this site use them including me and they are awesome for cold and hot smoking.
Yes it will work, smoke for flavor can be added at any time during the cook.
See the post quoted above yours.
The A-maze-n smoker is a good idea for future smokes if your going to do it while at awork. another thing you can do is start it at night so you can get the smoke absorbing while your home and then let it finish while your at work
