25x20 grow room lighting

If you were going to convert a 25x20 room into a grow room, which lights would you buy and how many?

I'm jealous.. 25x20 is a huge space! (assuming this will be a flower room)

Also assuming you have the ability to cool it effectively...

I'm partial to 1000 watt HPS, either DE or SE would be fine - and I'd put 16-20 of those in your room.

That would give you roughly a growing space of 4x4 or 5x5 for each fixture, depending on how intense you want it to be.

Good Luck!
