Ventilating two rooms

I have two rooms, one for veg and one for flower. The room are next to each other and are each about 500 cf. I am wondering if I can use one powerful vortex fan, say 450 cfm or more and put split ducting in order to vent both rooms from one exhaust fan. Any feedback on this is appreciated.

It depends on how much heat you have to pull out, we don't know if you are using a bunch of 1000w lights or what.

Can be done, if you don't have too much heat to pull out.

Going to be using 1-2 600 watt hps in flower room and 1 8 bank of t-5 flourescents in veg.
