space/lumen/wattage ??

[Heads4]

a 7 X 6 ft. area..........
will 2 1000w HPS's and 1 400w MH provide not only sufficient, but high quality yields??

Hell yes! As long as you line it with mylar (about £2 a metre, its quite expensive) it should be fine.
You shouldnt have any heat problems in a space that big either. Hell, Ive got a 600w HPS in a closet thats only a few feet big and about 5ft high and the heat is easily manageable.
