What a great way to upcycle your wine, beer, or oil bottles! Just fill your bottle up with water about 2/3 of the way full, and top with the Wine to Watered adapter. Turn the bottle upside down and insert the end into your soil. The water will release slowly, keeping your plants hydrated. Simply pull the stopper out to refill the bottle with more water when it is empty. The adapter washes out for easy cleaning. Wine to Watered adapters are reusable and keep plants hydrated even in hot, dry weather.
