I have had fish tanks my whole life but I do not have much experience with plants. I am not ready to get high maintenance plants, yet, but was wanting to start out with some low light plants. I am going to be setting up my 55 hexagon tank again, which is about 29in tall. There is room for 3-18 inch bulbs. Is 29in too tall to grow low light plants with basic aquarium plant light bulbs? Sorry if my question sounds stupid, I am not sure if I am asking the right question...any help is appreciated
