The Thirsty Light Blinks helps solve this dilemma by letting your “plants” speak with you. This unique detector is a digital moisture meter that uses a patented process that interpret readings it obtains from the soil, offering you a (claimed) more precise measurement of the potting medium’s dryness, unlike other detectors that are readily available in the market. You will know when it is time to bust out that dusty watering can by seeing whether it blinks or not. for those who do not have green thumbs and literally need a signal whenever their plants get thirsty.
