Hey guys, I just joined today but I have been doing planted tanks for a long time, but my question is. I got a new 72 gallon bow and I want to do this up right. What kind of light would you suggest I do to be able to grow dwarf hair grass? The reason it is a problem is because the tank is so narrow, but I also have a top on the tank so if anybody has any suggestions on a system. I am thinking of LEDs or a halide.
