THX! Best part is that the room the cabs are in is lockable, and is built into a long skinny finger in the basement that juts out under the attatched inlaw apt which is 2 additions. That apartment has a seperate basement, so this room disappears due to the slick shelving we have in front of it on hinges. Also, the vents empty out under a big deck, so no noise or visible vents. It really disappears quite nicely. The actual room is 18 X7.5, so it will be hard not to not be tempted to utilize the whole space to help with this rediculous recession, but I am resolute to keep it small for just personal use. Like my name implies, its all for me! (well, there are 4 of us. I know too many people but we are all best friends for the last 15 years and I trust those dudes with my life and know them well enought to know they'd never talk and risk losing the best thing ever to happen to them!) I hope to get at least 6 oz a grow, an oz a piece per month, and 2 oz or so to throw around...friends family, sometimes a few buddies come over and your stash gets cut in half in one night! Any ideas on whether the 250 mh will be cooler than the 12 26watt cfls? Then I wouldn't have to aircool it and it would be a bit cheaper!
