400Watt w/ super sun 2 reflector....size of tent?

Looking at moving from my closet into a tent. I currently have a 400w with a super sun2 reflector, can 33 filter attached to a stanley blower. My plan is to only run 2 plants either a mod scrog or LST.

What size tent would be ideal for this? Been looking at the 32x32x60, 3x3x6, 48x20x60, and possibly the 36x20x60.

400 covers a 3'x3' area pretty well. I have the 400 in my closet which is 4'x2'x8' if you can do the 3'x3'x6 I think that would work well. how big is your closet setup?

ironically, its 4x2x8! Last run i had a 250 in there with a 2 plant scrog, but didnt get much coverage so i bought a super sun2 and a 400w ballast. The thing i dont like about the closet is my 4x2x8 space is only a fraction of the closet so I dont have it completely sealed and it makes for difficulty in scrubbing....im essentially scrubbin the whole 10x10 room the closet it in.

What kinda ventiliation do you have in there?

Been lookin into 3x3, but since im only running 2 plants im curious the best setup for that would be. Was thinking a 36x36 i could do 2 mod scrogs with the screen being 20x18 with plenty of room to move around.

I am doing a two plant soil grow right now....only about a week away from harvesting! I topped just above second node, let it grow out and set the net in before flower....didn't really LST kind of a light LST to open the canopy and let the other tops catch up. Fills the area pretty well. I do anywhere from 2-4 plants with my setup. Here are some links where I posted some pics

I ended up using panda paper to seal the front and have it so I can zip up open, close....to help avoid light leaks. I have a sun system 2 light and it has only a 4" duct so I run a 4" inline that pulls from carbon filter to hood to fan and I duct out to attic. It creates good negative pressure so as long as I am sealed up don't get much smell. I ended cutting a 4" intake hole and used some left over ducting and rigged it up to a small 5" fan I got from CVS which helped bring in additional air for my intake, before that just passive. I run around 78-82 with lights on.
