I'm thinking about adding another light or two, but then I'd have some crazy high watts per gallon. Thats another strange thing about halides.. They dont seem to be nearly as bright as my CF's, and now it looks like I may need to have far more watts per gallon to get healthy growth w/ the halides. All of the scientiffic data shows that watt per watt, halides give off more light. I suppose the plants directly under the light are getting much higher lumens than they would under the CF's, which simply goes back to the light dispersion issue.
