Best possible light setup for 2x2 (mini cfl vertical?)

Hey guys,

I got this 2x2 box with the following strains in it. I was thinking about what would be the best light setup for this.

A 250w HPS will be too hot, I was thinking about 150w HPS. but then I also thought of this vertical style grow, this seems to be becoming an era of vertical setups. I reckon they are very efficient too. I wonder how well this would work.




Here are the girls I planning on running.
All suggestions are welcome. Tell me what would you do if you had a 2x2 setup.

id probably go with a big cfl 250 or 300 or a baby hps cool tubed mate

I'm doing a lil veg room inside of my bigger flower room and it's slightly bigger than yours. just veg though. I'm not sure if I would flower with the CFL's, even with the correct 2.7K.
For my veg room I'm thinking a 3 foot 6-8 bulb T5-HO as well as some additional cfl's on the sides like in your photo. I have photos in my journal, but mine only has 4 cfl's right now, I just have a lil clone in it, then 2x600W flower room.

So if you must, possibly an 8-bulb 2-foot T-5HO + cfl. but like the other people said, I would make room for a 600W

Thank you good fellows, I was really busy today and didn't get a chance to think much about this. Your inputs sound good. I am just worried about the 250 cuz it gets very very hot in my room.
