60 gallon cube lighting

[kendo]

Hi, I have a question about the lighting on my 60 gallon cube , right now I have the 250w sunpod mounted on the legs that came with the unit. My question is, would I get better growth with a single 400w or would this be overkill. btw I am using a phoenix 14k.
Thanks

Probably not overkill, but you are probably going to get less growth than you would expect with the additional 150 watts. Id stick with the 250, and work on the water params if you want more growth.
