So my portable a/c craped out. The thing won't work past 110 degrees and its 105 outside and I got a 1000 watt hps inside so bacicly the 8000 btu unit has to go my plants are dying fast.I got a 465 cfm fan on the intake and exhaust in a room 567 cf im thinking about a 2000 cfm swamp cooler. My big question here is do you think with that type of intake and exhaust running constantly can I keep my humdity down?I need to know asap

if you live in a dry desert like area and thats why its so damn hot then ya for sure... if you live in a tropical humid area then no.
