Love these terracotta watering thingies! I had to pack all my plants into one room recently while I was renovating and I was worried I wouldn't be able to give them enough attention so I bought 4 sets of these and put them in my most thirsty plants. They do take up a fair bit of room in the pot but they look really attractive and hold a decent amount of water. I have noticed that the water is absorbed at different paces, hopefully based on the plants' needs.
