Hello. I am new to the hydroponics hobby, and am currently growing a winter crop of hot pepper, watermelons, and beans. So far, so good, using an ebb and flow system. I am using General Hydro nutrients, and a tub full of clay pellets. (no rock wool)

My question: what is the ideal # of cycles per day for this? I have seen so many different recommendations. Anywhere from 15 minutes, 3 times a day, to 15 minutes on every hour. Not sure what to make of it.

Thanks in advance!
