Description from Manufactum
Height 16 cm, Ø 7.5 cm. Weight 290 g. The shape and size of the cones can vary. Comes without a bottle.
This terracotta cone will water the plant when one is away on a short holiday or is otherwise unable to perform the task. The cone is equipped with a connector that fits onto most commercial water bottle caps. One simply makes a few holes in the cap, screws it on a bottle filled with water and pushes it into the cone, which together with the water bottle is pushed into the earth in the pot. The ceramic material fills up with water and slowly transports the moisture through the porous terracotta.
