Hello,
I've got a question concerning the times when to activate my
pump in my flood and drain system.
My mesh pots contain ~0.4 L or 0.1 gallons of expanding clay and I'm trying to grow beans. The flooding takes about 15 min und the draining about 3-4 min. There information I found on the internet differ quite substantially. Some suggest that I should flood 3 times during the time the grow light are on. Others suggest I should flood every 45 min.
Which flooding schedule do you suggest? Which is a good beginners book on hydroponics?
Greetings
Stein
