Just read through your whole thread... definitely looking better now! A few random thoughts:
-- You might be able to cut a hole in the closet ceiling for ventilation, depending on how your apartment is situated. Use a hole saw if you can and save the plug that comes out. You can put it back in there with joint compound later, paint over it, and voila! Plus, if you cut the hole in the ceiling near the wall with the door, odds are nobody will ever see it anyway.
-- Trying to start seedlings in 3-gallon grow bags is going to mess with your watering. Use the small cups to start.
Learning along with ya... good luck, man.
