any assistance.... please....

i have a closet 2'x6'x8' and i want to make a 3 chamber system. 2x4 for flowering. i'm planning on using a 400w hps (sealed and cooled by air from/to another room). how big should my inline fan for this be? it will be a soil grow. i will have a 2'x2' space for veg. with a ? 200w? mh( cooled as well i think. what kind of rotation should i use. 1or 2 new plants every 2-3 weeks on rotation. i could probably sueeze 6 at a time. or just go with 4 at a time? i have grown once b4 years ago. it was a learning experience.

any advice would be appreciated... bigger light? fewer plants? go hydro?
is this even possible..

Sounds like you want your flowering chamber the same size as mine. Check it out.

You should grow many small plants in that sized area in a dwc. In an 8 foot cieling you could grow small plants on top of eachother and have 2 flowering rooms on a 2 by 4 floor space. There are pics in my thread of some pretty heavy yielding small strains. Also, if you have a cooltube vented the room is still going to need to be vented separately. trust me on that. it will get hot in any 2 by 4 room with hid even with cooltube. good luck and check out my setup for 14 plants in 2 by 4. its going pretty well and also has pics of another strain im growing that seems to yield and grow about the size youd wat for that room

heck out my page. it might give you a flowering setup idea as its the exact same size. It utilises small strains grown on 2 levels on a 2 by 4 fotprint on the floor. So therefore 4by 4 grow. hope it gives you some ideas. holds 14 plants

Sorry
