First Grow, Cooling 2 600w Hps

Ok as of right now i have one 600w hps i have a 500cfm inline fan, temps are good. I want to add another hps cool tube fixture of 600w, my question is is my fan strong enough to cool the plants, my grow space is 2 1/2 feet by 5 feet long and 8 feet high, i was thinking of doing it like this


{FAN]

-----{light}----{light]

im 2 weeks into flower, my second question is would another 600w even matter at this point in the grow? if so would it be a huge diffrence?

I run two sixes per fan just like you do for a total of four 600's. I have no heat issues or anything. I did makes sure to use the cool tube for killer heat movement! Much better than the typical hoods that catch and hold hot air.

And it would help your harvest of course! More lumens= more bud!

ok cool, right now i do have a cool tube 600w hps two weeks into flowering, like i said with the 500 cfm inline fan. I do also have a scrubber on the end of the exhaust....(which is in my attic.) should i put it inside the grow room or does it even matter?

The scrubber really is up to you. I do not have one and should since I am six and half weeks flowering! My entire block smells all day and that aint cool...

lol so the scrubber shouldnt screw with the airflow? make it worse or anything.

It slows it down some but I never heard anyone complain much about them when using them.
