need a new lay out

i'm currently using 2 32"x32" tents, one to veg and one to flower, and i bought a 32x60 to replace my flower tent.
i'm using a 400 watt hps to flower, but it won't be big enough to cover the whole 32x60.
i have 2 400 watt hps i can use, or i can use one hps and a 300 watt 3500k led flood light to supplement one end of the tent.or....i have a 250 watt hps i could use.......i also have a phresh filter, a 190 cfm inline fan, a 240 cfm inline fan, and 2 240 cfm 6 inch booster fans to use.
i'd like to just use the 2 400s, but i'm not sure about temperature control.
suggestions, diagrams, and candy welcome.

I would suggest using the 2 400's in the bigger tent. If they have duct entrances and exits you can just connect the filter and duct to one light, then connect them together with another length of ducting, and then connect the last duct to the exit and the exhaust fan.
