Go

If you go with MH's on that small of a tank, you will need some good fans, or a chiller. All lights produce heat, but MH's will produce more heat. Price out chillers, and you'll find out that they are not cheap. Fans can also add a fair amount of noise, so that is something to consider as well in the office. While I personally really like MH's over T5's, on that small of a system, you may want to choose the T5's, unless you go with a chiller.
