thanks! that's what I needed to hear! this will work for my set-up with no prob right>>?
I don't see why not I made two homemade iceboxes hooked one up to my 600w hps reflector in a sealed 3x5x7 room ran 65 degree tap water through it and it kept my room at 80 degrees. I plan on getting that chiller from eBay soon, if I had that on a reservoir temps would be very easy to control.

1/4hp to 1/3 hp per thousand watts is a good rule of thumb....

im geting a 2hp chiller for 6 1000 watt lights, i will run 8 ice boxes off that chiller... 1 per light and 2 extra wall mounted for additional cooling.

1/2 hp for one light and two ice boxes SHOULD BE PLENTY, but there are a lot of variables... dehumidifier, climate, ect. to concider.

well you are right on things to consider...so i will be using a dehumidifier, as well as cool the room with the other Ice box...climate is warm to hot and humid...in S.Fla will have 440 cfm windtunnel 6 exhaust fan connected to a can 66 filter, a 293 cfm inline fan for light, co2 boost bucket, 2 6" oscallating fans on each side of tent, reflector and fan thermal heat sheild from hydro innovatins, insulated ducting, house A/C will be set to 78*, tent will be on a interior wall in small bedrom and I will have thermal shield on all interior walls and cealing of room.. how's that?bongsmilie

before i spend a lot of cash

is air cool just the same as liquid cool, cant they get close also, and with air cool do you push ac air around the bulb or just fanned air, and in all cases how much closer can they get

light............................................. distant
600w not cooled............................?????
fan aircooled .................................?????
a/c aircooled..................................?????
water cooled..................................?????

fillin what you know
can anyone tell me the numbers. (it does not have to be a 600w'er what ever you have info on)


and if you could answer in the above formate +rep
so noone?????

cant really give a accurate answer without know your ambient room temp, how fast the air is exchanged from the room, the size of the room, dehumidifier, what size a/c, chiller, reflector size and shape, ect..

but roughly for a thousand watt i would guess...

light............................................. 1000 wattt

1000w not cooled............................ 2 feet or more probably


fan aircooled ................................. 2 feet, but depends on the fan's capability and temp of incoming air used to cool the lights.


a/c aircooled.................................. a/c that cools ambient room temp to a lil under 80 degrees will allow you to put a thousand watt slightly under 2 feet. if the room is in the 60's than you could probably go as close to 15-18 inches... I've never heard of someone hooking up ac directly to the ducting if thats what u meant.


water cooled.................................. with a big ass chiller and a ice box on each light you could probably go as close to 15-18 inches....

but again this is a hard question to answer without knowing EVERYTHING about your op.

I wouldnt buy a chiller/ac with the intention of it being so i can put my lights a couple inches closer... its more to cool the overall temps of the room so the plants will be happier and give better results. IF you can lower your lights a little to, than thats a bonus for sure.

hope that helped a little at least.

I use a grow tent. 3x4x7 and a 1000 watt. Air cooled. Sun system 2 to be specific totally sealed once you duct tape the edge. I take air from outside the tent which has ac then run it through the light my temp in the tent is always 8 degrees above outside room temp. The room is at 71 the tent is at 79. As far as the distance

1000 watt
Not cooled. 36-48 " above plants. Temp bout 92
Air cooled. I keep it at 27" above temps 79 with room 71
Air cooled on light mover 24" above temps still the same as air cooled

I can't speak on water cooled never tried. But electricity and water to me not a good combo
Hope this helps. Smokem if you gotem

yea i saw, and i dont believe for one second that you could cool your room full of thousand watt lights with one or even 5 of those home made AC fans...

im sure it would do what they say it would... cool a 200 sq. ft. room that had no lights or or ballast or dehimidifiers ect...

if you are in a small closet than it might help a little if you had the right chiller and used enough copper tubing with the proper fan.

i usually have my 1000 watt lights around 20 inches from the canopy and my room temp is about 74-80 degrees

I'd make to changes to that system.
1. Make the holes for the hoses smaller
2. Dump ice in that cooler too instead of just water.
they put ice in it, but any ways it only last 2-3 hr
but if you replace the cooler with a deep freezer then you may be on to something-- you could use one deepfreezer for more then one fan and more then one light
