Hydro rons 11 plant garden?

Has anyone used this system or know if it is good for flowering clones? I just built one and will post a pic soon. Here is a link to where I got the plans. It has pictures, plans and the works. Thank you for any comments or suggestions. http://www.hydroponicsonline.com/11plan01.htm

what luck have you had, thinking of building it as well.

I built on and the details were a bitch. I mean like leaks. I got them all solved and ran the device good. Very easy. Then i read The device has problems. The roots will gorw into the tubes and water pumps will have a hard time pushing the water up. I read that somewhere. Screens will help. You cant move the plants but if they are clones so i guess you wont have too.
I only have a 400 and i thought if i had a square i could get better use so bought a table instead. A 3x3 flood table. Before that I diy one with a 6 dollar hd mortar mixing tray and an 18 gallon rubbermaid. Worked good. Used ebay ebb and flo fixtures.
I am fine so far with ebb and flow table but i have the contraption in the closet still. Nifty idea, lol, i saw it on another sight with a whole room done in them but the poster got the advice i just gave you from some one else and switched to ebb tables as being simpler and effective. Everyone loves the ebb table.

The trick is to use party cups like pots,fill the cup with growrocks place Rockwool cube in cup ,place cup in 2ltr. I used a soldering gun to put holes all around my cups and slightly roll 2ltr bottles in warm pan to round the rough edges. Never had a root issue.
