Whats the best hydro system for scrog?

So i'm new to hydro, i'm planning to do a cabinet grow using a 250hps and SCROG method. I'm pretty much ready to buy a dwc bucket but don't understand how I would easily change the rez when my plants are tied to the screen? Thanks!

This is what i plan to get http://www.amazon.com/Stealth-Hydro...TF8&coliid=I2SPH2ER24M5PO&colid=3C3HXZKYXBPWJ

Dont buy that, make one instead.... to empty out rez, just drill a ball valve onto the bottom of the bucket...

Dude- if you look at the DWC that you want, it already has a drain port on the bottom. As Sunny says, just add a valve.

here is a cab i just built and posted in another thread, it was simple to build and im using 2 5gal buckets. the net pots are actually in the shelf that the screen is attached to, i mounted a ratchet hanger on each side all i do is pull the straps up and the whole shelf moves up as one (plants, screen everything) that way all i have to do is pull the buckets from the bottom change water then slide them back in and lower the shelf easily done in 10 min. dont buy the system just make it (its so much cheaper) that way you can chose the things that matter like air stones/air pump.

Cool thanks for the replys, yeah i'm going to make my own from a ten gallon storage bin just found a pretty good tutorial. I really like your setup drgreentm.
