well a 250w would cover 2ft sq so i guess a 150w would be about 18" sq

50 w/sqft is the rule of thumb for flowering and 15-25 w/sqft for vegging.

So a 150 is good for 3 sqft, a 250 for 5, etc....

I've run 75w/sqft using a 150 HPS and 50 - 100 w/sqft with CFL's.

More light above the minimum gives higher yeilds but double light doesn't mean double yields.

id go for 18" deep 24" wide for a 150watt hps, 3sqft.

agreed, 1.5x1.5ft stretching to 2x2 if you add a couple of cfls at the sides.
