Your plan sounds great!
As for the variables, I would say definitely get both a 400w light and an carbon scrubber. You have plenty of space to dissipate the heat with a hood so you may as well get the most light possible.
As for the smell, I have a small cab with just 2 plants at a time; they give off quite a bit of smell, enough so that without a scrubber the entire house smells.
Make sure to have an intake near the bottom of your closet space.
Definitely try out hydro, you will love the results.
Keep us updated on your progress!

Good plants reek. If you vent into the attic, most likely the neighbors wouldn't smell it but why take the chance? A cheap carbon scrubber will pay for itself with peace of mind alone.

I've never seen that type of filter. Is it activated carbon/charcoal? Is it made to reduce odor or something like that? I would be worried it wasn't the correct kind of material but if it was, you have quite a handy product imo.
Now you've got me thinking, I could use that to make an inline carbon scrubber; a goal of mine for quite a while.

Wow, good find! Where did you pick that up? How much? Furnace section?

The equipment list sounds great. As far as the hydro system, I prefer recirculating DWC buckets. I tried multiple plants in a single tub and its a pain in the ass if any of those seedlings turn out to be males because the root systems are inexorably tangled; you have to damage the roots to get him out. With recirculating DWC you can get away with a much smaller pump as well, for my four bucket system I use a tiny 60gph submersible.

Sounds like the tub will work great then. Maybe ditch the misters, but im a fan of very simple DWC systems; less parts, less leaks/clogging.
Thanks. It was pretty easy to build, maybe an hour total. It took about a gallon and a quarter to fill mine, but don't do what I did and buy 1 gallon and have to go back to fill the last bit. If you have time to wait for an order, I would get a five gallon bucket of the stuff from e-bay or someplace like that because it will drastically reduce the price. I paid more at the fish store for my carbon than for 5 gallon of it on e-bay. You will have to replace the carbon every other grow anyway so you may as well buy a lot of it.

I looked into those, It seems like they would work to me. I would build a specialized unit for the fogger head though because the commercial ones wouldn't be able to hold enough liquid and might clog/fail.
As for the pump, go and by one with 2 air nozzles and a decent gallon rating from the pet store; no need for something fancy in a closet grow. The air stones now, those will cause heated debate. I have always used the cheap blue ones but the silica reusables are looking more and more appealing.

Nope, I knew exactly what you were talking about. The same fogger heads are in every cool mist humidifier, thats what I meant by commercial units.
I would build a blower for the head in any case though, not just set it in the rez with the plants. Two reasons: first the roots will grow into the solution eventually so you would need to aerate it, defeating the purpose IMO. Secondly because the roots will strangle the fogger by growing on top of it and such, clogging it.
All you would need for the blower though is a rez to float the fogger in like you mentioned, a lid for said rez, a hose (think vacume cleaner size) and a pc fan to blow air into the rez, forcing the mist up and into the sealed tub for your plant roots.

The pump would be unnecessary I think, but an airpump and fogger should work for you. As far as keeping the roots off the fogger, I guess you could just cover it with a net pot and manually remove and roots growing into it every couple of days. The funnel is a decent idea, but I think it would limit the amount of fog that can get out. One more thing to check into is the average particle size generated by those fogger heads. There is a water droplet size range (I believe ~5-50 microns) that functions best for aeroponic gardening, you want to make sure the fogger is in that range.

Looking great! I just have a couple questions and comments.
What kind of fan did you end up going with? It looks like all you have is a duct booster fan which means you must have skipped the scrubber. Any idea what you will do about the smell?
That ducting you're using may be a bit too long, especially with a duct booster fan instead of a centrifugal or axial fan and its made of plastic which always concerns me when venting hot air. I suggest multiple, smaller sections of metal flex duct so that the run is as straight as possible, at as many light heights as possible. I know it will cause a bit more work, but with a decent sized HPS you have to get the most out of your cooling system.
Keep it up!

Yea, agreed ethno, basement air is usually pretty damp around here... I would check the hygrometer first off, you can find good ones at a reasonable price at a local cigar shop. Cigar shops have good ones that will give you an accurate reading, I've always been wary of the cheap ones from walmart and the pet stores.
That said, I have never really had a problem with humidity when growing hydroponically and it gets pretty damn dry in the winter. The only thing a low humidity level will do is increase transpiration rates (unless it gets ridiculously low) which means you will have to top off your rez water more often.
