Help me design a grow room?

Hi

I have been growing for 2 years now and have always done soil only autoflowering stealth grows. Everything I have ever done has been either inside a storage container or a hollowed out dresser with CFL's.

I want to rig up my crawlspace in my basement to do another stealth grow with hydro this time. I am fairly handy but want to get some opinions and advice to help get me started with my setup. I have attached a pic of the space I'm working with. It is about 10 feet in length, 4 feet in width and a little under 4 feet in height. So far all I've got is a 450 Watt HPS and some storage containers from other soil grows.

The room is really cold this time of year so I don't think the heat will be much of a problem. At any rate, the duct work in the ceiling is running from my laundry room (dryer) to exhaust outside to the front of my house. I imagine I would be able to connect into it and expel heat from the hood of my HPS directly into the duct? Would this smell bad outside? Maybe I could put a carbon filter in the hose as well to limit that? When it gets hotter, I might switch to try LED grow lights, especially if smell becomes a problem while venting.

I want to build a bubbleponics system like the many DIY tutorials on this site demonstrate. The one thing I am worried about is the height I am limited by. Most of them seem to be using a large storage container. What is the minimum height of the container I must use? Also, what would be the best way to control height in this small space? I was thinking of trying a SCROG method?

I currently have a ton of lowryder #2 seeds from a soil grow I did before. I think those will work pretty well for this for now, but would also like recommendations from anyone who grew in limited height and found good strains for it.

Hi, always fun making a new grow room. The height will be a challange. The lowryder would be a good choice for the space. Botainicare has a 2x4 table that is 7" deep,the tray also has a lid that you can drill out for net pots that would work for dwc. Just make sure you keep your rez temp under control. I had to use a submersable heater so that mine wouldn't get to cold. A screen would help for sure help. The screen i use is a cement screen from home depot. the squares are 4"x4', use metal snips to cut to size since it comes in 4 1/2 by 8 i think.

I am going to go ahead with the lowryder. The thought I had recently though was using a single tray and cutting holes in the lid will result in wasted space. When I inevitably have a male plant, the plant will have to be cut down and that hole in the tray will not be able to be re filled until the next grow starts because I think the plans will need a different nutrient reg for the first 1-2 weeks while they are on veg. If I used a separate bucket system, I could keep a veg and a bloom reservoir, correct? sorry I am new to hydro but I think this is right. This way I would be able to do something more perpetual and start vegging a new seed the second a male is cut down. I am currently looking at the DIY tutorials for bucket systems on this site, any thoughts are appreciated.
