I have yet to read what your exhaust fan sizes are.
Run a big one for the lights and something smaller for the carbon. They make some large vortex fans and you can get a reducer to fit your light exhaust size. Maybe even oversize your carbon.
As always of heat is an issue, duct to the outside of the building. That or move somewhere like Alaska if you really think you require 70 watts per foot.
