We live out in the Philippines and these plastic drink containers can pretty much be found all over the place disguarded and dumped. The idea of reusing them for not only container gardening as seen in the photo but also even for transportation as “watering pots”. Makes a lot of sense as well as gets rid of disregarded plastics, making them more useful and recycled. But also even if a flower vendor you could just stick these under a flower display to keep the flowers watered while awaiting customers. Great idea!
