which strain to get for my attic

Hi everyone I was looking for advise on what strain to get for my attic space. The space is 20'x4'x4' lwh. I have 12 inch tall grow bags and a 8" ballast i may keep my ballast on a 45 degree angle to the wall and rotate my plants daily. If this doesnt work I'll try mounting the 400w hps/mh vertically, horizontally, or vertically w/o a ballast in the middle of the attic(and place plants around while rotating plants clockwise). My other question is what strain do you suggest, that can take the abuse of my training and rotating ( i plan on using LST and then cloning from it and letting it grow again untill they all catch up). I have a carbon scruber in the attic which vents air into my closet. I'm looking for a strain that will make good yield and won't die/hermie on me due to the stress.

Strains i am intrested in (but not fixed on):
1)barneys farm lsd feminized
2)g13 Labs NLx skunk feminized
3)Barney's Farm G13 haze
4)Lowrider
5)ak-47

Depending on where you live the attic is really not a good place to grow because of the extreme changes in the temp. Not only in the night and day temps but also seasonal changes. Where I live the attic can reach 120 degrees in the summer and plants will never survive that kind of temps... Unless you have an insulated attic I would scatch that area and relocate.. Good Luck
