starting out

[Insane-inda-brain]

okay, i'm thinking of building a grow closet using the famous C22 cabinet. i'm thinking of putting a 400 hps light hydrofarm daystar or a eurosystem, 6" fantech or vortex and a scrubber. what size of filter should i get for my fan? i'll be going hydro. any recommendation or any changes to this setup i'm thinking of building.

i also have a chance of buying a used supercloset with a 400 mh for $600.

inquiring mind wants to know.

thanks
