Venting tent with air cooled hood??

Working on a new setup and had a few questions about venting everything. Some of this stuff hasn't arrived yet so I cannot technically test it out temperature wise yet. Here's some specs:

- Gorilla shorty 4x4 (48"x 48" x 59") w/optional 9" extension = 68" h

- Sun System yield master hood (6" double ended)

- 600w hps w/dimmable options @300w, 450w, and full 600w

- AC Infinity Cloudline s6 (6") w/6" carbon filter & ducting

1) I don't like the idea of pulling out air through the scrubber/hood and out, should I dedicate a fan for the hood only and would a 6" AC Infinity booster fan @265 CFM work?

2) I would hope the AC Infinity Cloudline s6 @402 CFM will pull through the scrubber fine but would that same 6" AC booster fan mentioned above be acceptable for intake or could the 4" @106 CFM possibly be an option?

3) Am I overthinking here??

I only have background with cheap dwc setups at 400w closet situations and obviously that's pretty hot with no fan ventilation, I would like to do this properly. I realize my intake conditions can determine some of this and I have every available option as far as that's concerned. I prefer to keep the electric bill low, I don't like the idea of three fans honestly and could've went cob/led or something else of course, may possibly do that at some point. Any advice would be greatly appreciated, thanks!

When I vent tent with air cooled hoods I pull through the hood and then through a carbon filter. Pulls out heat from light and exhaust from tent, in one go. 6 inch fan is plenty good. Passive intake (no fan on intake) for tents is fine, I've done passive intake for my 8x16 flower rooms too. Long as your out take is strong, you'll pull in plenty of air through an intake opening or hepa filter.
