I have a Aquafarm ( GHE ,clay pebbles hydroponics.) should I run the pump constantly or
do it with regular intervals say, 5 min on 15 min off. Do I run it at night? Any body any suggestions?
I do have a cycle timer ( mojo).
I prefer to run my pumps 24 hours a day as long as you have good drainage. You shouldn't have an issue with clay pebbles. By constantly recirculating your nutrients it keeps your solution fresh and oxygenated. It's the same concept as an aquarium setup.
