All my tanks are open top and I use two lights over them to get high wpg, so they are kinda covered with lights...lol
I get the lily bulb in the fish department at walmart they have two kinds, lily both red and green and apons, I get a 50% success rate on sprouting.
Yes I do get flowers on the apon bulbs but never on the lily bulbs...wish I did....my giant one I have in my ponds get awesome blooms...pretty pink flowers.....
Sounds awesome! I'll look into the light requirements before I do anything. My main tank has java moss now, and a dwarf anubias which is really nice. Got rid of everything else. Almost got rid of all the vallispernia but little shoots are finding a way of surviving. The java moss is enough to create oxygen for the fish, I don't use an air pump anymore. I always keep an eye out for low light plants now to complement.
