Air cooling Lights - CFM and temp question

So i have my medical room setup and its been running fine but i am looking to tweak things and hopefully save some money on power as well.

I have air cooled hoods, but have been running them with the glass out and just using the AC to cool everything. This works pretty good (temp at canopy is usually around 85), and my room is sealed (i supplement with CO2 as well) so i dont get much smell leaving the room and my carbon filter (just being used as an air scrubber recirculating in the room) gets the job done well.

I am looking to air cool my lights, but wanted to know some opinions and get some input to see if there would be a better way. Here is what i am thinking:

Going to be pulling fresh air from inside the building i am in (my room sectioned off inside the building). this will be ducted to each light INDIVIDUALLY (not daisy chained) and ducted out to a home built box in the attic with a 3000cfm whole house fan pulling the air through the lights.

My questions are this:

1. Since the air in the building can still be pretty warm (air temps in the building to 90+ degrees) will this be effective?
2. will this be enough CFM to cool 6 lights? there are fans that can pull close to 8000cfm if needed

dont think i have left anything out but please ask if you need more info and thanks in advance! :joint:

could i get away with less CFM? I could get 2 800 CFM fans and use 1 for each side. any suggestions on which would be enough?

Also, is this over kill? I mean, could i get the same results by daisy chaining 3 together or would it be more beneficial for them each to get their own air supply?

I have never been able to cool my lights to more than a few degrees above the ambient temps of the room the tent is in. If the temps hit the 90's you will never be able to pull enough air to cool down. AC is the answer but it has to be balanced with the exhaust capabilities so you aren't wasting cool air.

So what is your recommendation to prevent wasting cool air? I'm going to be dealing with 90-100 degree weather in the summer and want to be prepared! Should I get a more powerful AC unit to compensate for my 720 cfm fan exhausting air out of the box? What would you recommend?
