Ok i'm planning on making a single bucket ebb and flow. my buckets hold around 5 gallons, i'm planning on filling one up with clay pebbles, with the ladies being started inside small rockwool cubes. my question is, how often should i fully flood, how long should i leave it flooded? i was thinking 4 floods a day at a half hour running the pump in veg of 18/6 and 3 a day in 12/12. Does this sound good or am i way off?

I flood THIS diy Ebb & Flow system 3 times a day for 15mins

right on, thanks for the info mate, and btw nice set up
