First Grow Room - Please Help

For my first grow, I decided to try to take the cheap route and built a PVC frame. I am farily impressed with how it looks and is holding up under my array of CFL's. However, I am slowly realizing that this is not going to work in the long run. I have a large room to work with, and plan on getting HPS lights and all the good equiptment when I have the money...so it doesn't really make sense to skimp out on the room itself. And I just don't think the PVC can hold the weight of lights, scrubbers, fans, etc.

So the new project will be to frame with wood and see how many of these pvc connectors I can return ;P I am a total noob when it comes to wood working..and growing for that matter. The room in question is an upstairs bedroom with carpeting, a ceiling fan, a ceiling vent, and one window. Question: Would it be better to:

A) Simply throw a wall in the middle of the room, going all the way from floor to ceiling, dividing it into 2 sections? Then put hooks in the ceilings and hang every thing from chains? I would block light from the window and then use one section for veg and the other for flowering. The problem I could see with this is the fan and ceiling vent getting in the way. Or

B) Instead of just making on wall from floor to ceiling, I would frame a box that is 5' wide, 7 feet deep, and 6 feet tall. This would be the flowering room. I would run extra boards across the middle of the top of the frame to hold lights, fans, etc. This would eliminate the problem of things on the ceiling getting in the way. It also seems easier to hang the mylar this way. This is the route i'm going towards.

I'm also trying to make this something that I could take down in the next year or 2 if I decide to sell this house. And hopefully the room would look decent after. Is that possible ? Will I have to rip up the carpet to do this framing or can I build over top?

Sorry for all the questions , just a noob in need of help. Bcharley, i'll take any help you offer, or anyone else for that matter.

Roots, you don't really say what the end goal is here. How many are you looking to have in flower and how many in veg. Keeping a mother or mothers?

i am newish my self and to start i wouldnt say go mad with a whole room as you could spend out say $/£ 500 on the room and it all fails it would be bad news id say get or build a tent and learn to grow for a few months and try hydro/soil find out how you wanna grow your crop then once you have the basic ideas on growing then go for the room

Ow...my end goal is to fit as much in there as I can. I figure if I have the room to do it, and have no other need for the roo, why not go fairly big? And if I do it right the first time, i won't ever have to rebuild my flowering chamber again. So I am leaning towards buliding a box, or a room inside a room since it's kind of big. Then I will just use the rest of the room that is not boxed in for veg. and the mother.

Nitro..I will take that advice and just do the box. Tents are just to small and seem flimsy to me. As far as getting the hang of growing, I am not at all worried about that. I have tried single plants before with good results, and the green thumb runs in the family. The only thing that should hold me back is only having CFL's right now, but those can easily be upgraded later without anymore work, unlike the grow room.
