I have 4wpg, 6500k lights, with anacharis, hornwort, green wendtii and red wendtii, marimo balls, and java fern. I don't use a special hood, it's just a standard incandescent hood, fitted with two 20 watt compact florescent light bulbs, 'daylight' variety -- my problem, though, is that it heats up the water quite a bit.
Anacharis and Hornwort grow like something's chasing them. My crypts are new, so I'm waiting for them to settle in yet. Marimo balls are sort of like algae in tribble form, I like them. My java fern is so tiny right now, that you can't really see that it's there. I'll be adding java moss, next, but I haven't figured where yet.
I'm thinking of adding some anubis nana, petite, as a foreground.
At the moment, my tank is ugly ugly ugly, but I'm working on that. I started out with just one stem of anacharis and one stem of hornwort, and now I almost have enough to be considered 'heavily planted'.
