I am building a small ebb and flow hydroponic system (thats the one where the tub fills completely with water and then empties out). The plants will be put into rockwool, and then into the tub. How many times a day should my pumps be turned on, and for how long should they run for? (my timer can do intervals as small as 1 minute)
