How small of a grow box can I use a 250 HPS?

[VErginHarvy]

So, I am going to build a compact grow box and use a could cfls to begin with.

But eventually will upgrade to a 250 watt HPS.

So, considering ventalation will be good, how small of a grow box could I use a 250 watt HPS you think?


Please help.

I attempted the search button. But, really nothing that answers my question directly, hoping one of you can help!

i constructed an area in my closet thats 4 ft high, 32 inches wide and 23 inches deep, and i have a 250W hps. works fine. you may have some temperature problems at first (that is if youre shooting for 78 degrees) but they are easy to work around.
