Lighting

I have a choice

2 x 38watt t8 flourescent tubes, or
3x 54watt t5 luminaire

Which would people use for a 240litre tank mainly for plants ?

Thanks

For economy the T8's.

For performance the T5's.

I'd go for T5. 2 x 38 watt tubes is not enough for high light plants
unless it's supplemented by some natural light.

Thanks for the replies. One other thing though should I add an undergravel
heating cable along with the t5's.

An undergravel heating cable should improve the growth of your plants, but
it's an extra expense. If cost isn't a problem, go for it.

For more plant advice, rec.aquaria.freshwater.plants is good.

Please let us know how it turns out;

Undergravel heating isn't as popular as it was 10 years ago. People who
have tried it say it doesn't make much difference. I would spend money
on a good laterite substrate instead.
