Welcome to the Farm rezz :rasta:
Im sure you will love it here, and good luck with your attic set-up... Im not sure your dimensions or what light you are using, but an air cooled hood and a good inline fan or can fan should probably be a good way to keep temps down...I know my attic gets hotter than balls in the summertime.
I think Hubcap summed it up pretty much in his post. More people will see your post in the right subforum. Everyone here is infinitely helpfull, and the amount of info collected here is just astonishing, so Im sure you will find an answer soon...farmers helpin farmers is what its all about.
Im sure you will find your answers quickly, and just have fun browsing around at all the breeding, growroom set-up and strain info, and of course all the amazing pics in Cannabis Photography (one of my FAVE sections here):smiley_joint:
Well, Im stoned and rambling, so just surf around and enjoy the Farm!!
