What kind of plants do you want to grow is probably the more appropriate question? Because appropriate lighting depends hugely on that. Also on what kind of fish.
[quote Generally you want to be within the 3-4 WPG range I believe, as this will grow most plants but won't be so much as to stress the plants or be overkill for nutrient uptake. [/quote]
I had to down grade my 4 WPG tank because it was stressing my fish out being under glaringly bright lights all the time :P I knocked it down to 2WP and they're all much happier.
