To protect from power outages, I aim to have a least a couple of inches of roots in the solution at all times. Otherwise I would aim to keep none of my roots in the solution. I have a way to vary the level of nutes as the plants grow, but I keep spraying the entire root system about every 10 minutes.

I hope that gives you some ideas.
A couple of crops back I became overly lazy :-( and neglected my plants. My largest would consume about 5 gallons every six days to the point where one day I found the roots sitting in 2 inches of water. Now yes the nutrient solution was extremely concentrated!!! But I never forgot how explosive her growth became at that moment... I then resumed responsibility and started filling them up properly using a powerful air-pump. After I started filling to the top - the growth slowed down.

Although she was a producer - I now understand WHY she exploded "ROOTS WERE IN A MOIST ENVIRONMENT WITHOUT BEING OVER-SATURATED!" Wonderful thread my friend... Excellent post this is: Now I truly understand the KBS system and leaving the water level low with super oxygenation. My only problem is that without a controller - individual buckets at a low depth will consume my rational mind with pH imbalances. I need to make a controller or I will be going crazy once they really start to feed.

YOU GUYS ARE BOMB!!!!!!!!!! THANKYOU for helping me help myself... :-)
