It might suffice for some plants that don't require much light or if the tank gets a good amount of sunlight, even indirect sunlight if there is lots of it. I haven't tired to grow anubias at that low a lighting level but surely someone else on this list has. Using fluorescent lighting, I'd tried to aim for something closer to 2 watts per gallon. If using a store-bought hood with a white plastic refector instead of a mirror-like reflector, and conventtional fluorescent type bulbs (as opposed to power compact fluorescents) I'd want at least 2 watts. With a good reflector, a little less than 2 watts will work fine. It can help a lot to add CO2, which you can can get started doing rather inexpensively by setting up a bottle as a yeast fermentation tank and letting the gas output (CO2) buble into a owerhead or canister filter.
