I am also interested on how you would make an "Odorless Pig Pen", this is my first time reading about this. It makes me even interested as odor is one of the main problem we have to consider when we make our own pig pen.

Also, it is interesting to see that you have a bit different construction techniques from ours. I might learn a thing or two.

Can't wait to see the final result.
Keep on building. 😊
