Anyone using GH's EuroGrower? need advice.

Hello
I am looking to run a small time sea of green perpetual grow with a 600W hps in a 30" x 55" inch foot print.
GH's Eurogrower fits my closet like a glove and I think it would be great at harvesting 9-10 week plants every 2.5 weeks.

Is anyone using this: http://www.genhydro.com/genhydro_US/eurogrower.html ?
How long and in what are you vegging your clones?
What medium do you use in the 2 gallon pots?
Yield per plant?

Any advice will be greatly appreciated.

Anyone???
Could really use a few pointers on the grow medium.
I was thinking of using 1" inch rockwool blocks for clone/veg and then just droping em in hydroton in the 2 gallon buckets.
Will that medium work for this system?
Or should I use GH's CoCoTek Bricks?
Any help would be great.
Thanks

Still need help on using bato bucket drip system with perpetual SoG.
I am using Gh's 3 part nutes.
Will it be fine to have plants of different life cycles on the same bato bucket table?
Feeding the same amount of drip nutes to a day 1 of flowering plant and a day 60 flowering plant?
Thanx for any help.
