Did you make these yourself? If so, they are very impressive! You didn't happen to put together a 'how to' pictorial? How did you make the vents? Why did you pick the top rear spot for a vent? Just curious?
First of all I've added more pictures to the Link. The next group of photos are from the second vivarium I've built.
Yes, I did make these myself, thank for the compliment. I have always enjoyed making vivariums and Terrariums. If any of you all live in SA, TX, I'd be glad to help you make one. I can also drill glass. I would have liked to have made the back top vents further away from the back, but dumb me I didn't. When I start constructing the next one, I will take more "how to" photos.
