Before our EarthBox experience, we did gravity watering. We got the unique gravity soaker hoses, a 350 gallon drum and a bunch of pvc pipe. We put the water drum raised up about 6 feet higher than the mounds. We filled it from our deep water well. It worked well. Well, with the EarthBoxes, we wanted to see if we could hook up a hose and fill them from the water drum! It works great! From leaving the house, going down to the garden, filling them up and going back to house takes 7 minutes! We come back later in the day to do plant maintenance.
