"It's a do it or don't get a chameleon.".
Are you serious?? If keeping my chameleon has taught me anything, it is that there is
not just one correct way to do things! I think you can start with the well recommended all screen enclosure, but just be ready to possibly have to make some necessary adjustments as you go along. Everyone has different needs depending on their chameleon, location, house, room, , etc., and I think it important to find your own balance that works for you. Here in Alaska, I too have a huge problem with keeping humidity up, in our house during the winter months, all nine of them, the humidity level stays at a whopping zero, unless someone is cooking pasta or taking a shower. It isn't much better in the summer either. Awhile ago I changed my veiled chameleon's all screen enclosure to have three solid sides. I used plexiglass that I found at the hardware store sold in perfect sheets of 24x48. The top, bottom and front of the cage are still screen so there is plenty air flow to dry up any unwelcome nastiness that would like to hang out in there. I put in an automatic misting system and swapped out the utility sink base for a washing machine liner (*ahem* thanks Heika for the idea

) so that the 5 gal. reservoirs for the misting system would fit under the base. I am very happy with the way the enclosure has evolved so far and I am able to keep the temperature and humidity levels exactly where they need to be, that to me is conquering a huge goal. My chameleon's skin looks a lot better than it did before and he seems to be thriving, as well as the plants. I have never noticed a reflection from the plexiglass, maybe I got the cheap stuff that looks more like plastic than real glass, but in this case I am happy I did. Who knows, I will probably change his enclosure a few more times down the road as people find new or better ways to improve husbandry for their chameleons. I might find a better way to set things up on my own by experimenting, it's a constant learning experience and as long as you are able to make adjustments to the enclosure when it isn't working properly it can be a fun, rewarding and enjoyable ride.
