i would do a 250w HPS/MH With cool tube with a 4inch extraction fan with filter for outake and you could get away with passive intake

being that its basically 2ft tall 2ft wide and barley 1 ft deep a 4 in fan might be a little to small, with a 250w mh/hps i think, and
what is passive intake?
and would i be able to start the plants from seed under a mh/hps system. and which one should i get besides a 250w?

4inch fan will be big enough trust me, and passive intake is where the pull off the extraction fan pulls fresh air through a vent at the botten of the grow space

Cubic feet = length x width x height I think your saying your room is 2 ft tall 2 ft width 10 Inches length? If that's correct your a lil less than 6 cf the light u picked would b good but it's about the same size as the room so don't think it would fit? Is this a chunk of a closet or somethin? When u go to flower u would wanna change all the bulbs to the red ones since there's only 4 of em 2 blues and 2 reds won't produce a good amount of bud at that wattage. 12 plants seem like alot for that space . Heck one plant seems like alot for that space.... Unless u meant 1 or 2 2 may b possible. If I'm understanding u right on your room size I would just get like a 250 watt compact fluorescent with reflector use the cool blue for veg and the warm daylight for flower that's should be a lil smaller in size then the t5 system and have more watts

4 inch fan for Exaust is definitely enough any bigger for that space would b overkill just make sure u have a decent sized vent somewhere for a passive intake. Also I would use cfl for that size space

so for the vert have 1 4in intake and 1 4in exhaust? this room has to be almost smell proof. so for the exhaust im either going to make or buy something to cover the smell i hard something with charcoal. and i think i might jsut go with the cfls, have like 2 100w?

Man u r really crammed on space with the reflector your only gonna have like a foot to grow minus your pot size if u can try to add height to your space that would help alot. IMO u don't need an intake fan just an Exaust If there's somewhere air can get in the room the negative pressure from the Exaust fan will pull fresh air in without letting air or smell out. as for a filter 1 or 2 plants isn't gonna smell much u don't need to worry about neighbors if u have a room mate they might get a whiff if there nearby your growspace I would just by an auto odor killing aerosol dispenser and keep it near the space if u want a filter get the smallest charcoal filter u can find I think can filters makes a little tiny one and hook it up to the Exaust fan
