Ventilation design

[UniverseWisdom]

Im thinking about 600w hps in a 120x120x200cm growtent.

The light would be in a cooltube completely isolated used also as a heater during wintertime. I was thinking about using a 600cfm vent for the air distribution in a enclosed circuit,thermostat controlled.

Now one of my questions is: 1.Will a 600cfm vent be strong enough to push air through lets say 10meters ducting with air filter?

Second part im not really sure of is: 2.with enclosed lighting circuit i imagine the temperature shouldnt be that high but i imagine i will still need 2 more vents for growroom air refreshing.
My second question is: what cfm should the intake vent be? How strong needs the fan that takes the air out be? Scrubber included.

Also is it worth to scrub the intake air too? Thank you.

Same size fan for intake and exhaust with speed controller on intake fan. Drop intake speed just enough to get a little negative pressure. 600w in a 120x120 [5x5] is underlit. Only 24w/sq ft. Better off with at least 40w. If you're talking about 10 meters of exhaust, best to use straight metal duct pipe. Way less static pressure. Cheaper than flex duct. Good luck. -granger
