Best way to setup 2x250 HPS / 3 CFL

Hey everyone!

I'm just about done with my first grow and getting setup for my next, however I'm trying to figure out the best way to utilize my lights.

My next grow is going to be a 4 plant closet scrog, and I was planning on using both 250 watters for it.

BUT,

I was wondering if it would be even more efficient to use a 250 watt for those 4 and the other 250 watt for another 3-4 (after I finish flowering my current) so I can get a perpetual grow going.

I was also thinking about possible ways to utilize the HPS' in a creative but efficient way as far as lighting the scrog or even just a simple closet grow with LST.

Any ideas? Get creative.
