Entire room for flowering , options please 11' x 13' x 7'

I currently have a DR150 5' x 5' x 7' and my plants are way to big and cramped in that thing. I'm just trying to figure out what I can do here to get more room. I have an entire bedroom. I'm currently running a 600w and a 400w ducted together like this: cf ->duct->light1 -> light2 -> duct -> attic. I also have a window ac unit

Here's what I've come up with so far:

1. ditch the tent and use entire room - closed loop on lights, and separate fan for cf. Would this setup require a hole cut in wall for intake or co2 supplementation?? If I did cut a hole in wall for intake (instead of using co2), how big a hold would I need to cut?
2. ditch the tent and use entire room - chain it all together ( cf ->duct->light1 -> light2 -> duct -> attic ). Would this setup work without co2 or holes cut in wall??
3. replace the tent with bigger one or BUILD something bigger than the DR150.

The room is 11' x 13' x 7'. If I did co2, what would I need to buy and how often would I be buying co2? I don't mind to setup co2 to make the room work, but I don't want to be hauling co2 around alot. I might be able to cut a hole from 1 bedroom to another for the intake so to not be using co2...

Are there any other options?

thanks in advance!

Its hard to say without seeing the room-pics?
I don't see any reason you would have to use co2 unless you really wanted. pics would help

Its just a normal bedroom with a window ac in the window.

If I don't want to drill holes in my walls, won't I HAVE to use co2 since there won't be intake air? Or is the ac enough?

i think the ac is enough.. i like this idea, are the walls white, you can make a little veg area too.

The ac is enough? for intake? I thought I would have to have like a fan or hole for fresh air coming into room? IDK

The walls are white. I already have a veg area in another room, but this bigass room is all fllower and drying

Now I'm thinking of also switching to vertical bulb setups. Check the pics, as you can see it looks like my setup is completely and utterly cramped and inefficient

In an open room that size, using those 2 lights and ducting through like you say in setup 2 You should probably get enough passive air flow in the room to not use Co2. Unless you have a perfectly air tight bedroom.

If you have the room dedicated to flowering and you don't want to deal with co2 a passive intake would be perfect and for the size I think an 8in circular hole would be perfect. Than all you would need to do is fasten a Heppa Cone filter and you are set.

It won't be airtight, there will be some air coming through doorway w/closed door and probably some air coming through closed window seal. Other than that its sealed

Do I need the passive intake or can I get by without one and without co2? If I use intake, can I get by with a smaller hole? just not sure I want to cut a hole in the wall. The ONLY place in the room to cut the hole so it isnt noticable would be a hole from my bedroom to the spare bedroom. How can I cover this hole when I move so no one would know?

btw +rep thanks for the reply of the cone filter! I suppose that makes it light tight also...

Would it be better/easier to just build a bigger box inside the room so I dont have to cut more holes? Or it pretty easy to patch them up once I move?

I run kinda what you're proposing. I use 8" intake and exhaust holes, four of them, 2 for the lights and 2 for air, with backdraft dampers. You'll have enough room for a Co2 generator in the corner. Put your lights on a 5.0 Commercial Light Rail mover. The propane tank for your generator will last weeks, can be refilled anywhere, and no one looks twice at a 20 lb. propane tank for your grill.

btw I'm also looking at possibly turning this into a vertical bare bulb room.

I've been reading in the vert section, but there's not much info. anyone know what I would need to switch to vert? What i was thinking was just have the 600's with a fans blowing under them upward and then have my exhaust ducting above the lights to pull hot air out of room through CF. And just use my window ac to cool off the room. Would this work? Would I need to still cut a passive intake for air coming in??

I'd rather avoid cutting holes if I can. Would the above setup (vertical bare bulb) work without cutting intake holes?
