Re: Compact Fluorescents-Screw in

I'm running 55 watts of PCF (5500K) over two 20H tanks and both grow 
cabomba carolinia at a *very* high rate. I don't think you need 84 watts to 
do it. I have noticed that the combomba seems to like a lot of iron though 
and I can see the difference in growth if I don't add iron for a few weeks 
and then add some as an expieriment.
