Killfrenzi, you should start your own thread, instead of jacking someone elses.

Pitbull, that space is large enough to run a HPS400 with an air cooled hood. That would be your best option for yield in that space. If you cannot do ducting for some reason (hint: take the door off its hinges and replace it with a used one from a salvage store, or panda film, unless company is visitingm then re-hang it to look discreet), you won't be able to grow with any HPS in there anyway. Plants need good ventilation more than any other single thing besides light and water.
