that's a bare minimum. i would recommend you get the largest enclosure that is within your budget, since you are probably going to want more than one anyways....lol you don't really need a uvb light. but if it makes you feel more comfy, then go for it. therm/hygro, don't cheap out on this one, they are the most crucial instruments in the frogging arsenal, so your best bet is to go digital. stay away from the dial gauges, they are prone to be less than accurate. there is an excellent care sheet at the top of the tree frog forum for white's, (i'm sure you are probably reading that now...LOL). then go check out the vivarium section and see other's enclosures. you may just find some inspiration for your new future pet's home
