you should fill then drain
 

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 ?

5 1/2 hours might be to long of a time. One of the reasons why plants grow faster in hydroponics is that you are force feeding them every hour or so with nutrients and with dirt the roots have to go looking for nutrients in the dirt. The plants will only use as much nutrients as they can absorb so you have to make sure you give them plenty.
The air stone goes in the tank and only needs to come on when the pump does.
