So there's this 1000W HPS over a 4' x 5' area and it doesn't seem to be covering the plants in the corners very well... anyone else have experience with this?

It's got an EasyCool 6" reflector... check it:

Hi-Tech Garden Supply

Also, the light is currently only like 15-18" over the tops (12" for the crazy stretcher). Should it be raised to 24" or so to get greater coverage?

I was under the impression a 1000W would cover a 5' x 5' easily.
