Hi Morgan,
I think this tank looks
awesome! Not all these plants came from me but the ones that did should be medium light plants. Using less intense lighting, or changing fertilization, or no CO2 I believe the only difference you will see is growth rate, and perhaps color intensity on new growth.
Of course all these plants can be grown well in 'low tech' tanks. I like low tech , just not my focus. My focus is high light plants, and color intensity
When I first started growing these plants I had fluorite substrate and duel T5HO strung across my 7' tank (this is the equivalent to low light-low tech). No CO2.
I love posts like this. The evolution of tanks is fun to see.
