As greenery is life so when some one see a greenery or visit garden he feel fresh. I am also fond of gardening and so many plants already in my homesteading. Now its the time of technology and every field of life take the benefits of latest technology. So there are so many devices and apps available for take care of our plants which gives us opportunity to feel free about their nutrition. "Sustee" is just looking as pencil or stick which can check precisely the moisture of plant. So we can easily know from sustee when we watering it. @replayphoto very amazing and cool hunting.
