The Easy2Grow self-watering Garden system is literally as EASY AS IT GETS! The internal AQUAvalve uses gravity to provide the right amount of water to roots in a natural wet/dry cycle, so no electricity is necessary. Gardeners simply fill the pots with their preferred growing medium, connect it to the included reservoir, and watch as the Easy2Grow system goes to work! This Double Easy2Grow Kit includes two 8.5-liter square growing pots, two-pot tray and lid, instructions, and everything else you will need to grow!
