Help with design and heat issues

i have a 104 square foot grow room,and im having a hell of a time maintaining optimal temperatures. once i figure it out, the weather outside gets hotter, and screws my setup all to hell!. basically i have a 220cfm vent exhaust fan blowing in from the bottom corner of my room from another part of the house(blows in cool-ish) air. and i have 2 1000w hps/mh lights going(non air cooled or cool tube) magnetic ballasts. i use a 435cfm inline fan for removing heat and creating a negative airflow...

however, i see my temps raising to 80-82 degrees quite often after a few hours of running, due to magnetic ballasts and 2 1000watt lights going and buring the air and reducing humidity too.

is it wise to add the filter to the front of the fan and have flex duxting coming out and going to the roof? or taking off the filter and putting it at the end to increase airflow to the fan itself for better sucking power?

can people refer me to their BEST exhaust setups and intakes? and what is the best way to combat heat in the summer if the air you are using is also hot?

im an all organic grower, so chemical techniques ill disregard, heat issues are the only thing plaguing me, and its so hard to fix, its rattling my brain!.

also, help with adding humidity ? do not suggest cool wick humidifiers, they dont work with 2000watt setups..LOL.

That's big, I have a 400cfm extractor on a 12 square foot space. Apart from more passthrough, may be the best to get cooled hoods or cool tubes and run the extractor like so: filter, fan cooltubes / hoods and then exit. Next to that would be hvac, apart from power concerns you could get a unit that modulates temp, and humidity.

I'm assuming you have an 8' height in this area which means that your exhaust is seriously under powered.


104x8=832CFM just to exchange your air once a minute.

+15% for every non air cooled light. 124CFM *2 = 248CFM of extra airflow for your 2x1000w lights.

+20% for a carbon filter 166.4CFM.

832+248+166.4=1248CFM Required to ventilate and cool your room.

Perfect, like what I said but with the math to back it up haha.
