While I fully understand what you are saying, I believe that if more folks tried it, more and more would realize that it is not a situation where mandatory fertilization and
co2 is required. When folks step out of the rut of "it must be done this way" and start experimenting, I think that alot of eyes would open up to a realization of a multitude of different successful ways of doing things.
This hobby is too interesting to be narrow-minded about the ways to be successful. Step out and step up...be brave and experiment. I am not saying I can grow every plant there is to grow. I have however, found a huge assortment that I can grow (More then I have room for), and so I have achieved success in my minds eye. Something I consider to be a nice tank, with very minimal cost and almost zero effort. That to me is an enjoyable hobby!
Edited to add: I didnt see the question on the lighting..it is a 78 watt odyssey fixture.
