Which is better for plants...

[doreenjoy]

I'm downgrading to a smaller tank, and I'm confused about wattage per gallon, etc. Which of the following choices is better for plant growth?

1. Eclipse 1 hood on a 10 gallon tank (15" high) -- 15 watt, 5,000k, 18" flourescent lamp.

2. Eclipse 12 system -- 13 watt, 5,500 k, 13" compact flourescent on a 12 gallon tank (17.75" high).

I plan on keeping the lowest of low-light plants, but I'd like to give them as much light as possible.

Thoughts, comments, opinions?

neither, You may be able to get away with growing java ferns but don't expect much.

Personally I'd go for the Eclipse 12, slightly more water volume and a taller tank=more stability and easier to scape, more plant options.

I'd downgrade further and get a 10/15g tank with an incandescent hood and then use screw-in cfl lights. Cheaper than the eclipse system and more lighting for plants. Use a pair of 10-15w for a low light setup or 20w for more plant variety.

Yes, I *know* neither of these options is ideal. Just want to know which of them is the lesser of two not-ideal situations.

It's been a long time since I looked at incandescent hoods & I didn't realize CFL lights fit in them. Guess a trip to the LFS is in order.

Most crypts and anubias will grow just fine at your wattage.
