Moistly

Don’t be put off by probably one of the worst words in the English dictionary, “Moist”. Moistly helps you take care of your plants by alerting you when they need some fluids. Perfect for the inner city urbanite, the device simply sticks into the soil and when the plant needs water, Moistly will start to bleep and blink by playing a short melody and flashing a green LED. It helps you keep plants alive by preventing both under- and over-watering.
