First time tent grow, need help with airflow

So I have this new tent, it's 3x5 and 6'7" tall with two top ports and a bottom intake. I have some 6" flexible duct but need to invest in filtration gear. Are there kits that you can buy that has fans and filters in a bundle? I need advice on duct fans and filters and where to look so I can start pricing.

Not sure if I will be using a 600w hps Virtual Sun Lamp or a new Led. I haven't decided yet. Thanks

Fuck LED dude. 600watt ballast and a ushio hps. Get a 6" fan and a speed controller. Always pull air through the filter, never push air through it.

Peace
