Hell, if you have the room for it. I would go ahead and get six of the y's so you can double the lights that you can use in there. That is one of the best setups like this that i have seen. Very nice. I still have all the cfls from my first grow and i just might make one of those for another small grow while my others are in the hps room. If so i am going to copy yours to a T. Thanks for posting some pics of it.
