You don't need to have two separate rooms for photos. I have, and I'm sure a majority of the people on this forum, have grown a photo in one room or cabinet. Are you trying to get a perpetual cycle of autos going or something?
I would recommend Dutch Passion's AutoUltimate, Euforia, or Extreme. I have never grown any of them, because they seem too "hempy" for my liking, but I have consistently seen journals where they yield. Also, Heavyweight is a good company for autos. Skip Fast and Vast; that shit smells like a nursing home. Wipeout Express is bomb, and I pulled down quite a bit under like a couple big cfls. If you go with Seedsman, avoid the Sour Diesel Haze. I grew it outside last year and she got to be about 10 inches tall. Decent smoke and all, what was there anyway.
