Room a little to hot help please?

i have a 400w setup in a closet about 4' by 2' and about 7' high the temp is usually around 84 degrees i already have a fan going through the light to cool it off but its still around 80 degrees the fan is blowing 265 CFM any ideas on how to cool it off more?

Hi .... 80f is an optimum temp , As long as you can keep it under about 85 your all good , As long as your plants have adequate supplies of water and a good air cuiculation .

The plants function best in moderate temperatures - between 60 and 85 degrees.

If your worried about it being to high you can just drop a cople of 2ltr frozen water bottles near the air intake ... But i think 80 f is just about right ?

What stage are you plants at ?

Yeah 80 is right about max, if you're using co2 than 85 is max. Im also having trouble keeping mine below 90

Will probably have to get a portable AC

80 isnt bad at all, as long as you keep it under 85-90 tops you'll be fine.

I am from the VERY deep south and our temps have recently been in the upper 90's, and soon to be 100+. I run a 4x2x5 tent with a 250hps cool tube, the room the tent is in keeps an ambient of 77 to 79, the tent during lights on is 80 to 87. I run a 170cfm fan w/carbon filter that is ducted into the ceiling. Inside the tent I have one 9" floor fan, and two 6" clip on fans above the canopy that keeps the air moving nicely. I was using my 400w dual arc but temps went to 94, so just swapped out for my 250hps. I have a local friend that has been growing for years, and his temps run 88 to 95 with no noticable issues for him, and he has some of the best smoke. I was originally worried about my temps, but once I seen his temps I stopped stressing.
