The Easy2Grow self-watering planter’s internal AQUAvalve uses gravity to provide the right amount of water to roots in a natural wet/dry cycle, so no electricity is necessary. Growers simply fill the pots with their preferred growing medium, connect it to a reservoir with the included tubing, and watch as the Easy2Grow system goes to work for up to four weeks. This Double Easy2Grow System includes two-8.5 liter square growing pots, two-pot tray and lids, filter, instructions, and everything else your customers will need to 2Grow!
