you should fill then drain

[Jam]

Ron, Thanks for your time and effort in maintaining a useful webpage. In reading your past logs you mentioned that in a Ebb&Fllow system you should fill then drain, wait 30 minutes and start again. Currently, I am flooding for half hour (best the timer will do) and draining/ sitting for 5 ½ hours. So far, the plants look pretty good. Should I up the watering ? If so, should it be done in small increments so as not to shock the plants?
Air stone into the water tank or the growing bed ?
