Need Help On Upgrades.

Hey there

My setup currently worx, but was done with like no money to start....

4x4x6.5 grow tent
400w hps
1 18" fan over plants on light
1 fan blowing freshair into a vent, atm air vents out top
the room the tent is in is ac'd

upgraded to a 600watt
currently using it with same setup on a wing reflector
i know i need to work on the actual enviroment of the tent, my plans are 6" 440cfm fan to draw the air out of the tent with passive intake from ac'd room,
one of my biggest questions is should i go with a aircooled hood i dont rly wanna fork out almsot 300 for one but i can get a silverstar 6" locally fairly cheap anyone used thesem would it provide good light for 4x4 area.

i currently have to run ac on low speed max temp to keep temps half good 30 celcius outside with the 600

any suggestions and help are appreciated.

Redo...

So, These 160cfm Booster fans 6", would 2 of these suiffice for growtent enviro.. 1 (the intake) with a very free flowing fitler(just for dust watnot no carbon filter or nehting.. To help the intake side be a lil lower on cfm then exhaust also.....

600Watt HPS, Wich I have ordered a SilverStar 6" air cooled hood, i plan on a 440CFM fan for the hood no carbon filters, but somehting good for debris and dust etc, or maybe carbon filter, i'm not worried about smell...

Suggestions??, Comments??, Critisism?? Spell??
Lets here it thanx

all i can say are the booster fans are trash.

so you would suggest a bigger fan say 450cfm, and use that to pull air through the hood and tent with passive intake?

as you can see on my thread, i push air instead of pull but yeah i usew a 450 cfm fan.
