Question Plants only, what can I give up?

If I were to make a tank for just growing plants, what, if anything, can I skimp on?
Obviously, I need a tank, water, light and substrate[depending on plants.]
But do I need a heater, if the room stays above 70F?
Do I need a filter or anything to keep water moving?
Should I dose ferts, use CO2 and root supplements? I rather not go overboard with the dosing because I don't want to add work and $$ to this.

I'd like to have a long, short and narrow tank that's sectioned for different plants. Use the same lighting over each tank, four foot 80 watts light, resting on the tank that's hopefully about 1ft in depth. Would that be considered medium or high light?

This is a draft list of what I'm wanting to grow.
Aponogeton family, if I can get them to propagate.
Hygrophila Difformis [Wisteria]
Ceratopteris Thalictroides [Water Sprite]
Hygrophila Balsamica
Cabomba Furcata [red]
Cabomba Carolina [green]
Cabomba Pulcherrima [purple]
Nymphaea Zenkeri [Red Tiger Lotus]
Shinnersia Rivularis [Mexican Oak Leaf]
Limnophila Aromatica [Hippuroides]
Echinodorus Barthii V. [Red Melon]
Sagittaria Subulata [Dwarf Sag]
Hygrophila Corymbosa [Siamensis]

If you are doing a fish-less system, you will need ferts all the more. You may be able to get away with root tabs, if you don't want to do a dosing schedule. You have a lot of red plants on your list - you'll probably want high light and co2 to keep those plants red. As for filtration, I find my plants benefit from the water movement just as much as the fish, though in a fish-less tank you might be able to get away with just a powerhead? (Someone else with more experience feel free to pipe in...)
And keep in mind that plants need light + co2 + ferts. Too much light without co2 or ferts is just asking for algae (trust me, I've done it!). Lower lights lessens the need for co2 and ferts.

I think you could skip on filtration but you will probably need some water movement in the tank, i dont know about the heater but i think some plants do require warmer water to live

I don't dose my tanks with anything and have medium lighting in my current tanks. I've got some of those plants on the list in my tanks currently, never add CO2 or anything.

Was that light considered medium or high?
