I will give you a few options..
You can get the grow lights (walmart, lowes etc.. ) they are 24" and about 10 or 12$ each.. I have found that the original bulb will only last a few months.. but you can replace it with a ge aquarium/plant bulb and it will work just fine.
You can also take an 18" aquarium hood (or 2) and put a 18" aquarium/plant bulb in there..
And last but not least, I have an exo-terra like yours with a pair of coralife 9watt compact flourescent (CF) fixtures on it.. and the plants are thriving.. (great color and fantastic growth).
So, There are a few options from cheapest to most expensive.. the CF fixtures do have a lot higher quality of light.. but it is overkill if you just growing pothos.. as it will grow just about anywhere if you keep it watered..
Other than the light, you need soil, and moisture.. Now, seeing that you have RETF's, I am assuming your misting regularly.. this should be adequate to water most of the plants listed in the previous post.. and soil can be a simple coco-coir base such as bed-a-beast or dendrobedding.. I mix a few other things in mind.. but again, it depends on the plants..
The best part of having live plants in there.. frog poo becomes fertilizer.. so you can just leave it in there and let it break down naturally and help to nurish the plants instead of having to remove it..
btw.. I still miss thefrog..
