Well I'm glad to report the experiment was a complete success!
The peatmoss and baking soda do a great job of covering things and not allowing odors.
I put a big cupfull of peatmoss in first, then after I started using the toilet I would use a small cup of peatmoss and a small cup of baking soda to cover. A couple of times, when it was just pee, I only used the peatmoss.
I did lay the lid on the bucket, then just put the toilet seat cover back down.
My closet doesn't smell, which is amazing considering it is only 2' x 3', with no vents. That is good news because that was the size I had designed for my bus bathroom.
So,there you go people. Peatmoss and baking soda all the way
