Oh okay, those dimensions sound a whole lot better.

And wow, dogfood's got quite the nice setup...and THAT'S what they call scrogging...got it. I might actually look into that for the shorter tent. Although, I'm only condensing a 3.5' average heightened plant, so pruning it should chop it down to 2.5' shouldn't be anything (especially if I can take a 7' monster down to a 4' mid-size through pruning). I dunno, I may end up not wanting to mess with that screen...though I would like to try it at some point which is making me want to go find an old cabinet pretty badly.

By the way, a big thanks for the link to the soil growing FAQ (essentially). It's actually a very good reference for those nit-picky questions I like to ask :P.

Average height of a NL strain is about 3'-3.5' with a yield of 2.5oz.-3oz. (found these numbers based upon 4 different grow logs and on 3 different websites...seems fairly accurate since all 4 grows fell within that range, but obviously it depends on how well you grow). Which means you are correct in saying that I'll probably have to go to 4' to get anything as big as 3oz. off of each plant, but hey...I got the room to do it so why not? I don't think I'll have to go as tall as 5' but whatever happens happens; if they end up growing that tall I'll probably prune them a little bit to get it back down around 4.5'.

Okay, so tell me if my thinking is faulty. In the first tent, I'm going for one t5 8-bulb fixture with 6500K lights + two 90w LED GrowUFOs to support 6-8 plants (depends on what I can fit in there). In the second tent, I'm going for a 600w HPS + two 90w LED GrowUFOs to support 10 plants.

Also, speaking of floro, are people using 3000K for the flowering or what?...if so that's a hell of a lot more lighting that I need..
