Heat.
    #347818 - 01/14/10 07:21 PM (6 years, 10 months ago)

I'm a first time grower with a space 2FT x 3Ft and 4 Ft Tall
I have a Box Fan to draw cool air in at the bottom and two small window fans to push heat out the top, my grow box has a slit 2inch wide and 3ft long across the top to vent the heat out of and 2 INCH holes in the bottom sucking air directly from outside i would like to buy a 400Watt HPS but I'm worried about heat issues should the above set up be able to handle a light that big or should i go smaller?
This is the light im looking at and i have room to place the ballast outside my grow box...

hrm, I'm tempted to say run a smaller light like a 250.  But if you can buy some good fans and ducting you could probably keep the room cool.

How much cooler is a 250 vs a 400?

Cool enough, couldn't tell you honestly.  But it will be a lot easier to control temps with a lower wattage light in a small cab.  Especially with the intake/exhaust system you currently have setup.
