Can anyone recommend a good portable air conditioner for a SEALED 10x10x8 room? Its running a 1000watt HPS and 400 watt HPS both air cooled hoods. I should also mention that this is an attic room so the sun beats off the roof. It is heavily insulated an sealed, but I'm still getting some really high temps even with the cooled lights. I dont know much about A/C's so any info would be helpful. Thanks in advance for any advice!
