i have the exact same size closet, 5x2 floor space and 6 half foot high. a shelf along the top actually cuts the height down to five foot nine. I too was going to put a 400w light in there, but I'm on a budget, and the light, plus an air cooled hood, plus a good fan add up to alot of cash I don't have. So i'm being practical to my needs and buying a 250 instead. Here's my ventilation idea for the space, and I'm hoping footclan will respond to it as I'm seeing you all over these grow room threads, so I'm hoping you know what you're talking about. Anyway I said there is a shelf along the entire top of my closet. It's like a ceiling to the grow area really, and the nine inch high space above is like the attic. I'm planning on closing the closet door, having holes near the bottom of the door or small holes all through the door, which ever would be most effective, I could also run a four inch fan inline if it is needed. One oscillating fan inside the grow space blowing over the canopy. I plan on cutting a hole in the shelf to allow the hot air to exit the space and enter the "attic", then I plan on having a six inch fan blowing air out of the "attic." Where I am unsure is the best location size and shape of the hole. I can make a cut the length of the closet along the back of the shelf, taking like the back four inches off all the way across. Or I can cut off an end of the shelf, making a 1x2 opening at one end of the closet into the small space above. The inline would be opposite of this, and the fan would blow from the inline side to the opening side. hot air would rise up into the space and then be sucked out. I've read alot of manuals about ventilating catepillar engine rooms, super technical stuff, and I think I've gotten a good idea of how the air will move, but I'm still feeling indecisive. I could also make a large square hole in the middle, with a hood like thing reducing the hole to six inch ducting. run that to the fan and out, but I think that will only reduce air flow. These are all just ideas. Do you think they could handle a 400w, or should i stick to the 250. and odor isn't a concern for me.
