Grandparents engaged in the tricky art of indoor gardening may need some extra help, even if they're pros. The EasyBloom Plant Sensor is a flower-shaped, USB-enabled device that tracks light, moisture, and temperature in any spot in the house. When its finished collecting data (over a period of at least 24 hours), the Easy Bloom plugs into your Mac or PC and gives plant recommendations based on its findings. Other modes of operation include the plant monitor, which shows how specific plants are faring, and a water mode that tells you when it's time to hydrate your indoor flora.
