Is your darkroom built in a spare bedroom, or was it specially built for this? Just currious. I work in the garage at our house, we have one of thos nice new lightproof roll down doors installed for the main door, and I block out the windows. I still can only print at night though so it is kind of a drag. We are renting so I can't complain though... (plus the H2o bill is included in the rent!
