To solve that problem, just get a little bigger fan.QUOTE]

Are you using a 1000 watt system too? Because that's a whole new ballgame when you step up to the 1k watter.

If you read my posts, then you will see that I am using a 1000w. And like I said before, its relatively easy to keep these systems cool, as long as you got a decent exhaust fan. I think my fan is rated 170 cfm. Which is hardly the size of a lawnmower tire. I use it to cool the light and run the filter. Absolutely no problems with heat. I keep the light less than 1 foot from the tops. It stays about 75 in my room and inside the tent. A lot of heat in most setups is generated by light absorbtion. When u have a tent like this, There is VERY little light absorbtion, so there is little heat to contend with.
He's probably right about absorbtion. I have (had) a 4x4 tent w/1000 and heat is not a problem at all. The tent is ALWAYS about 2-5 degrees warmer than the garage it's in. It's almost always closed up (2 vents open at the bottom). I have to run a heater in my tent. I have a 8" inline turned down to about 300cfm. I'm replacing it with a 6" HO. Im also putting a thermostat on the hood fan so that the light will heat the tent when it gets cold.

If you have a good tent (GrowLab), a good air-cooled hood (Cool Sun), and a decent fan (Can-Fan), you should not have any problem with heat.

how tall are these 4x4 tents/rooms? just wondering cause i was thinking about setting a small room up and saw a 100 watter for cheap but thot that i may not have enuff space above my plants. so i guess my question is wats the minimum ht. requirement for a 1000 watt hps to be above the plant canopy?

I am using the one from secret jardin, the dark room 120, and its a lil over 6.5' tall. I dont veg mine long, so heighth isnt really an issue for me. I never open the bottom vents either. Im too lazy to go open and close them at lights on and off, and I dont want light leaking in from there. I just use a little inline fan at the bottom to bring in some fresh air, and i have some ducting hooked up to it as well, to make sure light isnt getting in from there. Its completely dark in the room at lights off, as I have went in the tent and closed it off to see how much light was getting in, and I couldnt even see my hand 2 inches in front of my face. The only time I really have to do anything is at watering time. Other than that, its set it and forget it.
