I'm having the same problem with the northern california heat. It was around 97 here today and it's not gonna get better. I have 9 afghani kush vegging and my ac only starts to cool the room where i need it when the sun goes down... : ( If anyone sends you some info on that situation, hit me up.. Oh, I would recommend 6" ducting hooked to a high velocity intake fan to cool those 1000 watters.. I gotta 1000 hps and even just having a regular fart fan (bathroom vent) works wonders 95 cfm.
