Like with everything in life it is always easier to do it right the first time lol, unfortunately that isn't always possible. I like to share my failures on the forum so hopefully others don't make the same mistakes.

Its a large part of the reason why Bill and I made the Vivarium Construction 101 thread, unfortunately it doesn't appear like it is being used

We take the things we learned from the last build with us to the next. In the next build we will discover all new ways to mess up lol.
