Do plants really need CO2, Florite Substrate, and whatever else? Can water and light just be good enough?

Actually this is more equivelent to asking if you could put a dog in a cardboard box in the vacuum of space, with water, and no food. The substrate is the housing, and part of the food, fertilizers are the food, and co2 is the oxygen. Co2 is needed for plants to grow no matter what. However this doesn't necessarily mean that you have to supplement it. Low surface agitation will help hold in the co2, and having a healthy fish stock will also help. Without ferts the plants will starve and eventually die.
some plants can be fine in a tank with no co2 or ferts. not every tank and every plant has to have them. they will do much better with them but should be fine.
yes there wont be as good as growth but they still can be healthy plants. my 20 gal long has only water and prime added to it. went away for a week and came back to a over run tank. plants were all green and grown like crazy.
