5 x 5 tent, 2 x 600, heat issue, ac unit or another fan?

I have 2 600s running on 9 2 week old plants, they are currently turned down to 400 each. Its about time to turn them up but when i do it gets a lil too hot. its at about 75 when they both run at 400 and 83 turned up all the way. They are cooled by two 400 cfm 6 inch fans that come to a joint and run straight through both lights. should i get another fan to suck air through from the end of my ducting or should i just invest in an ac unit?

thanks

Could you elaborate on your air system, you have two lights and two fans, where is your ducting attached and going?

Also, that is really a ton of light. Not saying that bad, but thats a lot of light for a 5x5, I believe 1 600-watt is capable of running a 5x5. Again though, not saying that a lot of light is bad.

But yeah, where is your venting, ducting, filter etc?

carbon filter is hanging at the top pulling air out at 175 cfm, and another intake at the bottom pulling air in at 175. the fans that cool the lights are right outside the tent and they almost immediately meet at a joint and then that duct goes into the tent and through the lights and all that gets sent into another room. i might take the fan thats pulling air into the tent and set it up at the end of the ducting from my lights. its a 6 inch booster fan so it could add the cfm i need perhaps? i could just get a different fan for the intake

Can you post some pics?

More light sources = More heat sources. My 6'x6'x6' tent has 2 400s set up but I rarely run both due to heat. But I only vent into the AC'd room the tent's in. Unless I cut a hole & vent into the attic...That's how it's gonna be. The room eventually warms up. Temps run @ 80-85 with just one 400 on.....up to 90 w/both on.

Try just one 600...You'll be fine in that tent.

after i hooked up the booster fan the temp dropped to 79 with all 1200 watts runnin, an intake fan to replace the other one should do the rest

sounds like you solved your own problem.. good job revo and +1 for letting us be part of it

That was informative, thanks

I'm moving up to a 5x5 in a few weeks and was going to put 600w hps + 400w mh and was hoping to get mid 80's, I don't see what's wrong with 1200w at 83 degrees?
