Grow room design

Hey guys, working with a limited space and trying to get the quality buds. My plan is to have a box that is 3.5ft long, 4.5feet tall, 22inch deep. ill be having two plants and just ordered the beans blue moonshine from dutchpassion. ill be putting in a 250hps and the somes cfls i have. for ventilation and odour, with this High Tech Garden Supply get the job done? I cant decide what i should try to do whether squeeze 3 plants in there or just 2 plants pending on whichever gets the highest yeild. any help appreciated.

i would do SCRog method

dont buy that BS filter!!! i just bought the 6 inch one and it couldnt even touch my 2x3x5 closet. JUNK!

I have a friend that used to run that exact 4" set up and you could smell it from his driveway.

so what do people do to make it not smell then

you could try a carbon filter, usually takes most of the smell away
