Advertisement I'm going to start lighting a few vivariums for live plants. I have a couple larger tanks already illuminated but what would be the most effective way to light multiple small vivariums(Exoterra nanos) that are next to each other? Should I just buy a light hood that would be able to extend to all the tanks or multiple indevidual hoods/domes and somehow hook them up to a single outlet? What would be the most energy saving form of lighting? As in wont rack up my energy bill. I'm sure dart frog experts would know. -JohnD.
