Well, daylight strip lights are good. just like coral tanks, the more light, the better they grow. its a lot like doing a refugium for the saltwater tank. there are special mineral laced substrates for planted FW tanks. i guess you can grow them with the substrate over an undergravel filter to make the nitrates. and lots of fish to feed the plants.
info on one of the forums too.
