I have a converted-aquarium terrarium that is currently happy in a north window. It contains a couple of smaller calatheas and fittonia (and a sad cryptanthus). I'd like to move it to a part of the house that doesn't have much natural light. Will a regular aquarium-top fluorescent light work for these guys? I want to make sure they have plenty of light, but I have no idea what kind of light or wattage to use so I don't bake the li'l guys.
