I am looking into getting a Panther Chameleon here soon and looking for the perfect enclosure. I have a Jackson Chameleon and I have been using a Zoomed Skyscraper Glass Terrarium (18 x 18 x 36) since I live in Colorado where there is always low humidity. I have an Exo Terra Monsoon Mister set to mist for 30 seconds every 4 hours and that keeps the humidity at approximately 75-90%. I have not found anything larger than that using glass to properly house a Panther. Im looking for any guidance as far as will the screen enclosure be a big impact on a Panther Chameleon due to low humidity in my area even with an automatic Mister or if compensated with a Glass Enclosure where to find something larger than 18 x 18 x 36.
36 tall is fine, however if you can increase width then it's even better!
There is a 36x18x36 Exoterra that would work perfect for a Panther. That's about the size of a Dragonstrand atrium (I think the exo is bigger) just be sure to elevate to the floor.
If you want something taller and 24x24ish instead check out
Protean Terrarium's they have all kinds of sizes (Sliding glass doors, Vs Exoterra opening).
Dragonstrand breeders, are also enclosed like glass, but are screen cages with PVC sides instead of screen. They come in taller sizes and would likely be cheaper than glass. However harder to bio in, will require there substrate bin. Easier to put a drain hole in though lol.
There is also always DIY route. Build a wooden Viv with glass doors. Then you can make it just the size you want and no stand needed.
I would say stick with glass. Screen is a compromise, and it's only suggest as it's easy for new folks, and even then only US keepers. EU keepers use Glass and Knockdowns, and the Quick frame Vivs. Hardly any of them use screen cages.
Glass+backgrounds/walls+bio best IMO, if you have experience with it already especially.
I'm not sure why the screen obession with US keepers. It's easier for noobs, and that's where its benefits end.
It doesn't hold humidity, it doesn't hold temps, it hurts Chams feet if they climb on it, it requires more misting. To me, It has zero benefit except being cheap, and easier for new keepers.
