Thanks!

The drain plug is a great idea and I am looking at it for ease of use.
As the
ebb and flow proved, I will liklely do 1
nutrient change during the grow. It seemed to work well in giving the lettuce and addiional few weeks.
On the water levels. It can get reduced by about 3 gallons and still provide for the roots, but that level would concentrate
nutrients (I belive), so I keep it within about 85% of the optimum. When I forst start the small plants, I drop it about a gallon to force the roots to reache deeper.
This tip was suggested by a forum member and proved itself....so I'm sold on the results.
