If you worry about entrusting your lush philodendrons to neighbors or family while out of town, the Rain Maid™ Automatic Plant Waterer will ease your anxiety. It automatically dispenses the perfect amount of water into the soil every 3 1/2 days for up to two weeks. Just fill the reservoir and stand it upright in the pot. There are no batteries or moving parts to worry about; a simple flow regulator does the job.
