It is going to be very hard to get adequate light at the substrate, where plants begin growing, without having super high light up near the top of the tank. Perhaps a MH light hanging high above the tank could work. And, planting the tank will be a major challenge, too. You could stick your whole body in the top of the tank, but that is not for everyone. If you go ahead with it please, please start a journal on it so we can enjoy it with you.
