Don't kno if imma get teh ballast included in a system of teh seperate style. You got any idea?
I ended up getting one with the ballast connected and all in one piece.
Its heavier to hang with an included ballast, but a straping young guy like yourself should be able to do it no worries.
It is a [mine] 600W HPS , and it isn't very noisy or hot.
I have been leaving the main vent fan (also cools light) off now and again for Co2 and it never has reached 90 yet.
more is always better so I would say 400 rather than 250
and a 400W HPS all in one, is usually cheaper than a separate ballast type.
there is also the 200W CFLs
