That would be a very nice space for a male of several species including jax, veiled, panther, fischeri. Probably not enough to support a pair. Besides, your female might get stressed with the constant presence of a male, and if she became gravid you would have to separate her anyway. Depending on how humid you can make the space (more for jax and fischeri, less for veiled, panthers in the middle). Consider that if your room gets too warm for jax or fischeri and needs to be cooled with an AC it might be too dry. All those plants sound fine. A thought. You could build a cage frame but only screen in the back and sides to confine movements somewhat, but leave the front open. This would give you the ability to shield walls etc from water spray or humidifier fogging. You will probably need to use some type of humidifier or a misting system to keep that large a space humid enough for most species. Most of those species love houseflies and moths, so free ranging them will cause some trouble! I had a male fischeri who loved flies over all else. So, I set up a large cage that could be closed in when the flies were first fed, then I could open it up for free ranging once he'd eaten them all. Worked pretty well. Good luck!
