1st question ever. Would you check my airflow?

Hello there everyone!

So this is my first time putting up a question after trying to absorb all I could from here. Thank you one and all. My question is regarding the air flow setup I have created. Wondering if anyone could look at this, and give me their opinion. Too much, too little?

Sorry I don't have the dimensions of the cab, but roughly it's about 3" deep, 4" wide and say oh 6" tall.

I'm planning on 4 5 gal bubble buckets

Light is HTG 400W HPS/MH magnetic.

Maybe tonight I could put up a pic of the actual cab.

But this is about the air flow. I'm hoping the intake - cooled hood - exhaust will take care of a good chunk of the heat from the light. Not sure if I need that extra little exhaust at the top.

The DIY large carbon scrubber, not sure if I need a HIGH powered blower (Lasko/Stanley) or if a good powered 9" fan will do the trick. I want to exchange air, but scrub it as well. Too little, not enough air exchange. Too much and I just might pull air through the scrubber too quick and not actually be scrubbing anything.

So here is my rough drawing. Thank you all so much for the help, couldn't even begin to think of doing this without all your help.

cheers big ears!
