Grow Tent Temps a bit too high (1000W)

[thelight413]

Hey everyone,
I just started flowering with my 1000w HPS in my 4x4 grow tent, canopy temps are sitting around 80-82, down just a little lower into the canopy.. its about 77 degrees. I am running an active air 400 cfm exhaust fan through a scrubber thats hanging at the top of my tent. I'm also running a Max Air Pro series 420 cfm fan to just cool the HPS light, bringing air from my bedroom, through the reflector, and then up and out into my attic. For the record, the tent is setup in my bedroom and temperatures are around 72-74 outside the tent in the room when the lights are on at night. When the lights are off, tent temperature is about 71-72

So, what could I do to get those temps just a little lower in the tent when the light is on? Should I remove the scrubber from the exhaust fan? Maybe switch my pro series fan to make it the exhaust fan rather than the light cooling fan... Any suggestions are much appreciated. Thanks everyone!

P.S. Can post pictures of the setup when I get home from work.

Any way to bring in cooler air from outside?

Yea I could run some ducting from a window with an intake fan, I'm in colorado and this is my first grow, not sure how cool the air gets at night in the summers outside. Hopefully it stays cooler than the interior temperature of the house...if not then I assume my next best option would be an AC unit for my room specifically. Would putting another fan in the tent possibly decrease temperature or is there already maximum air movement going on.

I have one large oscillating fan(20 inch) and then the exhaust fan (400cfm)

If night time temps stay above 70 at night you may need a/c.

Adding another fan inside the tent probably won't do much but blow around hot air.

Do you have an air cooled reflector?

hello light i have the exactly the same problem.. what did you done ?

mid summer temps bring temps on the high side.
AC in the room?

Temp in tent will depend from ambient temp if you don't have a/c unit. 80 f isn't bad. Don't worry what do you expect in the middle of summer. It is normal 1000 w to run 6f -8f -10 f over ambient even with air cooled hood.

Tent/canopy temps are determined by intake air temps, since you've gone the full measure on running air thru the tent and thru the light. What will help would be to lower the room temp. Or you could go to a lower wattage, especially during the last 3 weeks of bloom. How many inches of space is there between glass and canopy? Good luck. -granger
