My three test hydro buckets did so well last season, that I am adding more this season. As you see from the two pictures. First I lower the height the buckets by 8 inches or one concrete block. The nutrient tank was sunk into the ground with only 3 inches sticking above ground. Three more buckets were added to orginal three. These six buckets will be for tomatoes plants. Plus I start work on adding a second row of buckets.
