The system once it is established is incredibly simple and easy, although it does require attention. I have to fill my gravity reservoir atleast twice a week which is 50 gallons. The system goes through between 100 and 150 gallons a week of water. However, aside from nutrient and water top offs and phing once every week or so, it runs by itself. The growth is explosive and massive and often hard to control. Do not leave for 4 weeks while vegging!!!

I expect to yield around 6 pounds from this setup. We got around 4 last time and harvested early and had some problems.
