Tall Tank Lighting
Hello again Wild...
I use one bulb. It's a 6500 K, 32 watt, T12. However, it's a 36 inch bulb in a single bulb strip.
Two bulbs will work if that's your setup. Get 6500 Ks if at all possible. 15 to 17 watt bulbs is likely the best you can do without spending quite a bit more on lighting. The 6500 Ks are closest to natural daylight, which is what you need. I use bulbs from the local hardware store. GE has recently come out with an aquarium plant bulb that works very well. The local hardware store should carry them and they're inexpensive too.
Again, you have to go with low light plants only. Plants that require moderate light won't do well, unless they can live floating or you find a way to pot them and get them closer to the light source.
