Lighting and ventalation questions

Now lets say for a moment i was harboring ideas of growing with 2 and then later 3 600 watt air cooled HPSs.

And then let us also say in this idea the place i would be growing would be 100degrees out side in the day.

And then let us say the place i would be growing would be a 12x10 room in an air conditioned house cooled to about 76 degrees.


If in this dream world i planed on air cooling these lights, as well as ventilating the room, how would i best accomplish this task. Would i vent the room though a chain of ducts chained between the lights with one inline fan or would i require more then one fan to take out air & cool 3 lights, also should i get another fan to bring in new air? if so should it be larger, smaller or same capacity as the total air being exhausted.

Edit: also i have heard from two friends that supernova's are really good air cooled reflectors are those the ones i should go with or have my friends be brain washed by ad executives?
I hope i spoke English well enough.

You speak english better than most Americans

You can daisy-chain your air cooled reflectors or cooltubes together, just make sure your blower is powerful enough to do the job, and try to keep the number of duct bends to a minimum.

You'll probably want to add a portable air conditioner to the grow room.

Passive intakes should be enough

You don't need 2 separate blowers unless you want to seal the grow for CO2 reasons. Draw the hot air off the ceiling, cool the lights with it, pull the dirty air through an in-line carbon scrubber. Add a couple passive intakes - near the floor - to let cooler air in.

Ok thank you i was thinking about the window air conditioner you have conformed it for me i will get a energy efficient one to be extra safe hiding bills.

Is an 8inch inline @ 590cfm enough to daisy chain the three lights and vent the room? or do i need to buy bigger then 8? yes i have a co2 tank and unite and will be buying a control soon, could you explain to me how i would do it to seal it for that?
