We’ve ignored the cucumber in the cellar for the last several weeks with the exception of watering them once. The L.E.D. lights are on for ten hours per day, and total 25 watts of power, or 1KW every four days, or about $0.30 of electricity per week. They are starting to set fruit, have climbed over their tube and are heading for the rafters. I’ve rerouted them up a stiff wire and a chain, and readjusted the lights and the reflective material to offer them more room, as shown in the pictures below. They should be ready to pick in about two weeks!
