HPS Lighting

Hey, Guys! I am looking to get an HPS lighting setup between the range of 250w-400w. These will go in a grow room that is 3.5'Lx2.5'Wx4.5'H, and possibly be over a scrog setup (or a SOG design). What size reflector would be best for a room of this size, to get maximum coverage and penetration? Are there any brands/styles of HPS lighting (ballasts/bulbs/hoods) that are not recommended for growing?

I only ask because a guy said he would sell me his two 400w HPS lights/reflectors and 4 extra bulbs for $40. Sounds too good to be true, but I will not know for sure until I see them. I just wanted to have a specific idea of what I characteristics I should be looking for when I check these bad boys out? Thanks!

Hell of a price, I'd take the deal regardless of hood (reflector) and hope I get a larger growspace later-on. :thumbsup:

Bare Bulb - Uneven lighting, wasted lumens. (nothing reflected back to the plants)
Bat wing - crappiest of the bunch, barely better than bare-bulb. Uneven light distribution.
Parabolic reflector - barely better than a bat wing, but good enough light distribution for commercial grows.
Enclosed hood - better for enclosed area's or rooms with limited ventilation, but restricts light 'footprint'.
Cool Tube - Lowers heat from bulb, but is a pain to maneuver and takes-up a lot of space.

I prefer an enclosed hood, but it would depend on your intended use, quantity of lights you'll be using, ammount of growspace, ambient temperatures, venting and air circulation...

listen to rusty, he won't lead you astray.

Thanks guys. That helps a lot!
