This has never been a problem for me in 20 years of using them. I open the doors to feed, clean waters, take them outside, bring them back in, etc... There must be enough air exchange to keep it fresh.

For future builds I will have a regular double paned house window custom made at HD or Lowes for around $150. SoOOOOOO much simpler, easier and better. I will install with the "outside" portion of the window facing into the enclosure. This will allow me to "lock" the window and you can't get much more humidity and moisture proof than a window that is made to be facing outside. My Dad just built one this way and it came out fantastic.
