how many water cycles per day
 

is your 11 plant system a flood and drain system or a continuous flow system if ebb and flow how many cycles per day for both veg and flower and how long after filled do you drain them?

It's an ebb and flow. Let the water rise about half way up the bottles, making sure the roots get a good watering, but don't let the water go higher than the top of the medium. The over flow pipe keeps that from happening if it is set at the correct height.
Once the roots are watered, about every 20 or 30 minutes with grow rocks, the water should be drained right away. The overflow pipe allows you to water longer because most timers only have a 15 or 30 minute on time. But by know means do you have to water longer than it takes to wet the roots. A good cycle timer is a must for ebb flow gardening.
