go to htgsupply.com get your self a 600w hps/mh digital ballast and easy cool6 hood cost round 270-300$ plus shipping and i think it comes with a timer mines did
Yes and they also are much better at penetrating dense vegetative growth to help with your yield and for the most part offer a better spectrum of light than regular cfl's.
Shit mann if you wanna go in the direction where itz not putting too much $ on the electric bill than id say do both mann. I meen like get a relatively low power HID light say anywhere from 70 to 150W. and then run cfls with that (as many as you need). Then you'll have the right type of light and enough of it as long as you have enough lights. I always say 10,000 lumens per plant, and you'll be good.

3 foot by 3 foot?
I reckon 2 of these off ebay would be cool - Dual 125w Hydroponics CFL lamp & reflector grow light on eBay, also Hydroponics, Plants Seeds Bulbs, Garden Plants, Home Garden (end time 22-Sep-08 19:22:39 BST)
Otherwise - if ventilation isn't a problem I'd say 4-6 plants under a 400 watt HPS...

you really only need a 400w for that room 5-7,000 lumens per sq ft

Everyone thinks this..and rightfully so. I thought lumens were cumuliative like that..til I came on this site. someone correct me if Im wrong, but I dont think lumens add up like that. So you are getting a good dispersal of light...but your lumens are only as high as your brightest bulb.

and for a 3x3 i would highly advice against 600w. 400w your gonna need to do some work to keep that space cool. Cause i have 600w in a closet that is effectively twice (and then some) the size of your space. and i have problems keeping the temperatures down..then again I live where it is still 90 in october. Cooltubes are great, so are digi switchables. quieter (all u hear is the cooling fan on a digi). I think a cooltube would be good, they really do wonders keeping a light cooled with the right fan. Get a 400w digi-switchable and pack every centimeter of your space with plants. btw look into advanced training..or ScrOg..or topping or fimming heavily. cause you'll lose almost a foot with your hood of the height of the ceiling (less u can sink it up in the ceiling which is much easier than it sounds). hope i offered some help. peace.

this is true grasshoppa diffrnt points of light dnt ++++++up i have to find where i read it but will post it when i find it.... oh yea and their is a thread where a guy grew 1 lb with 1 plant scrog with a 400w in a space like yours(3x3) i will post it too
FYI HPS HID lights are almost twice as efficient as Fluoro bulbs are. So for those folks that think by switching to CFL or Fluoro will lower your bill they are wrong. HPS puts out almost twice the light power for the same wattage used. a 400 fluoro uses the exact same amount of power as a 400 watt HPS, except the HPS is putting out twice the amount of light.
And with florescents your still putting them as close to the plant as you can, right? So if you throw a hps into the mixture, itz still getting light from all the lights instead of one. I meen it might not be 25,000 lumens like i said before. But it still has to be alot of light ya know? if you add up all the light outputs, and then divide by the sq. ft. of your grow room you end up with a rough estimate, of how much useable light your plant is getting, right?
