This simple passive hydroponic system provides the perfect amount of water to your plant, ensuring you never over-water or under-water. Each planter set includes a ceramic planter, a glass water reservoir, 2 hydroponic wicks, a seed packet, and two coconut coir pellets packaged in an informative brown kraft box. To keep the plant properly hydrated, simply pour water into the glass reservoir whenever the water levels become low. It makes a perfect addition to the desk or shelves of both green and brown thumbs alike!
