What do you think of my setup?

Obviously what you see is what it is. 400w mh/hps switchable. The only thing I dont have is an exhaust fan but i usually just leave the door open during the day so id assume its pretty good. is there anything you guys would change? is the light too high? how far will I have to spread them apart when they are full tilt? and I transplanted them from cups 7 days ago, added nutes 3 days ago. do they look average for that amount of time? give it all to me. open to any suggestions. the more the better off I will be. thank you!:rastasmoke:

p.s. I think they got transplant shock or something because when I got the clones they were sitting in a tupperware container with about an inch of ice cold water...did that put me back any?
