I have 5 tanks which came with incandescent bulbs. I'd like to try growing live plants in my tanks. I'd be sticking with low light plants because my apartment faces north and I don't get a huge amount of natural direct light.
What kind of small light bulbs would work best for plants? Are the ones that came with the tanks OK or should I replace them? Is fluorescent or incandescent best?
I checked at the pet store and found some similarly-sized bulbs that were packaged as "plant-friendly" but they didn't give a k rating. Here's an example.
