The heat from a 600 watt HPS
    #3734426 - 02/05/05 09:04 AM (13 years, 9 months ago)

How high will my 600watt HPS raise the temps of my new closet Garden.

I have finally measured the space, its 3 feet and 10.5 inches across , and 2 feet 2.5 inches deep.

For a total(in inches) of 46.5 inches across and 26.5 inches deep.

From the SHELF to the celling its 5'9 (5 feet 9 inches) and from the floor to the CELLING its 7'11(7 feet 11 inches)

Tomorrow I am going to pick up a full 600watt HPS system(with a batwing as well )

I know that the ammount of light I am using is "good" , but how much heat do you guys think it will create??? (I imagine an experienced grower can estimate)

If my temps are at 55f-60f without the lights off, how how will it get in there with the lights on??? (BEFORE I turn on the fans??)
(my place is cold)
I am going to use ventalation , I know its important, but I am just trying to estimate "what" I am going to have to deal with.

The good thing is I wont put my plants in until I have everything running smooth.

your plants will be fine if you give them 2ft of headroom.
experiment though, you may be able to get the light closer.
sufficient ventilation should be able to take care of the heat,
not much to worry about there (assuming your using a remote ballast!).
With that much lumens/sq ft, you can grow some tight nuggets!
Can't wait to see what comes out of your room!
pick your strains wisely!  :shocked:  :grin:

just throwing that light in an unventalated closet would raise the temps about 20F give or take is my guess. with ventelation you can get it down to about +5F (from lights off temp).

There's a thin line between sanity and insanity... and I just snorted it.

If your whole setup is air tight you could probably get away with a passive intake and a fairly cheap exhaust fan, don't forget about dealing with the smell as well.
