It seems like the more I research, the less I understand. Some people say HC is a low to medium light plant, while others say you need lots of light!? So I would rather not go the route of doing a bunch of mods to the lighting. Would rather keep it simple with the LED lights so I can keep evaporation to a minimum.
Also what do you recommend for a nightlight (blue led setup).
From reading around here on the forums, HC needs lots of light especially for growth. A lot of people here have used way more light than they need and they get great growth followed by lots of algae. I think it is a issue with patience. Slow growth is better.
Option 2 ought to be good enough, though it might be a slow growth. Option 3 would be great, but you will probably have an algae problem at some point.
