Thoughts on my Setup?

This is my first grow and would like some input on any changes to air flow/setup of the air flow system or upgrades I need too make...I have two Tents in a room one for flowering and one smaller one for veg...

Veg tent: 32x32x63
Lighting T5 96 watts 8000 lumens 4 Tubes..
Will be adding more T5's for side Lights going down the poles...maybe like 25-50 watt T5 on all four poles..

Flowering Tent: 58x58x78
1000Watts HPS
Will be adding more T5 Flowering Lights going down the side poles as well...

Venting System:
Exhaust: (3) 6 Inch Duct Fans each is 150 CFM... 1 on top of each tent sucking air out of the tents..The veg and flowering tents exhaust lines will be connected starting from the veg tent too the flowering tent too the wall..the last one will be helping pull the air thru ducting/helping move the air from HPS in the flowering tent then to the wall...

Intake: 8 Inch Max Can fan 667 CFM Using it too cool both tents and the HPS light in the flowering tent..

Questions:
Is that enough Intake air too cool both tents and HPS 1000w Light with ONE FAN?
Is that enough Exhaust power too move the warm air out of the tents and HPS LIGHT

that's all for now I had a nice drawing of my setup I made from paint lol in like 20 mins to show too a friends so he could understand how I was doing the air flow but for some reason it won't let me upload it too show you guys so you would really see how I am doing it for the most part...

thanks so much for your input and thoughts

your flower room is going to be HOT as hell. 85* plus imo. also you want some neg pressure in each room. meaning you want your exh fans to be a little bigger in cfm rating that your intake fans. I had to run an 18" fan blowing directly under my hps (across the tops of my flowering plants) light AND run an 8000btu portable a/c unit when my hps lights are on. now im running 72* lights on and 74* lights off. before this I was running 87*. the temps in my veg room are 82* +/-2*. im also in a basement grow, my ambient tamps are 75* +/-2* and 45% r/h year round. I also exhaust ALL my tent air back into my basement, not outside. my a/c exhaust gets exhausted outside tho.

here is my setup

veg tent 4x4x7 dr120 tent
6" intake fan on 24/7
8" exhaust fan on 24/7
3 5" clip fans on 24/7
600w xxxl cool tube
6" 440 cfm fan for cool tube on speed controller 75% on timer w/light system on 18/6

flower tent 4x4x7 dr120
8" intake fan on 24/7
10" 725cfm exhaust fan matted to a MONSTER DIY (custom built) carbon scrubber with 120oz of activated charcoal (iirc 26"L x 10"w x 6" outlet) its huge on 24/7
3 5" clip type fans on 24/7
8000btu portable a/c unit blowing into intake port on 12/12 with lights
6" 440 cfm fan for a/c exhaust venting outside on 12/12 with lights + a/c unit
600w xxxl cool tube
6" 440 cfm fan for light system on timer with light

check out the link below. my first few posts should detail my setup further and should have pics of the setup as well.

Well from what I have found from light/fan company's in the FAQ says it takes about 150-200 CFM too keep a 1000w HPS light kool...SO to be on the safe side say 300 CFM and have 6 inch one helping suck the air out from ducting on the other side of HPS I think I should be fine just need to found out how much CFM I need for my flowering tent to see if I can still do all three with one fan but if not I have one more nice 6-8 inch fan I can use not sure CFM have to look it up but prolly about the same is the other one or use my 400w HPS light but not trying to go that way if I don't have too....Also my grow is in the basement like yours but my temps set around like 65-70 top now that it is getting more into winter think about 5-8 drop in temps down there so that might help too :) but I have few idea's/options I can do but thanksDemonTrich

No not what I am doing just what I found on a fan company's site saying that it takes about 150-200 CFM to cool a 1000w HPS...What I am thinking you can tell me your thoughts is now after what you have told me and from what I have read and what i got to start with for now is...One Intake line to cool the flowering tent and HPS light that runs at 450 CFM and use my Max can fan for exhaust that runs at 667 CFM and have 1 6 IN 150 CFM helping it pull the warm out of the other side of the light and just use my other two 6 IN 150 CFM to vent my veg tent for now until I can upgrade them...let me know your thoughts on that thanks again...
