any ideas about how to lay it out??

Will be an ok space to work with, Ive grown in a space similar to that, managed to squeez 4 in but on later grows I got more yield growing 3 and LSTing one of em. Just be sure to heat shield the roof (great piece of mind when your baked and there's a chopper flying overhead!) I ran ducting under the eaves and wrecked the roof just a little bit so I could get nice fresh air for my intake fan which then left me free to vent the hot air from the exhaust fan through a carbon filter back into the unused attic space.
