Self watering planters take the stress out of caring for your plants. The sand colored self watering planter consists of a 8" wide ridged outer pot that acts as a reservoir, storing one to three weeks worth of water for the plant, and a porous inner pot with a 6.25" wide opening that allows water to seep into the soil as the plant requires moisture. Now you can go on vacation or leave the office for a week without worrying if your plants will be alive when you return!
