Definitely unique. Outdoor enclosure? Or indoor? And for what kind of tortoise? It will definitely hold heat in, maybe too much if it's outdoors. Definitely can't wait for the updates.
I like it. What kind of box turtles are those? They are pretty. And the holes lower in the barrels, I think were the original lids are, get some airflow through. It will be easy to expand if you want and should hold humidity well too. I like the way the lighting ends up through the barrels , sort of shady but yet not pitch black. I hope that made sense, it's kind of hard to explain what I mean. Very creative.
1.2 ornate wood turtles. Water changes are easy I just flush out the existing water with fresh when needed the filter helps a lot and keeps water changes to a minimal, however I will add a drain soon. Thank you all for the kind words .
