should i buy a light mover?

I have a 5x5x6 flowering room with 1 1000w air cooled hps hood. Would my yield benefit from a light mover?

if you have a stable setup, it couldn't hurt.... if you can afford one.
you can definitely get more plants under the same light that way....

I wouldn't waste my money on one I would run a 1000 in a 5x5 and keep my plants a half a foot away from the walls so light can bounce around them basically keeping in a 4x4 area. thats an efficiant use of light and space6 ft tall kinda sucks but what can ya do.

definately not with a 1000w hps, thats all you need bro... you need more vertical space! how close are the lights from the plants?
