WMF Gourmet replacement wick for herb garden 0641306040 and 0641316040. The WMF indoor herb garden made of polished stainless steel and high-quality white plastic is a dream for all hobby cooks or plant lovers. Herbs give dishes that special fresh kick, especially when they are self-harvested. This also works on a windowsill in the kitchen, because all herbs need to grow is a good location and water. The irrigation system of the herb garden helps with the right dosage. The plant gets as much liquid as it needs via a glass fibre wick. At average room temperature, the water supply in the tank will last for several days.The herb garden for the windowsill is also available as a set of three. Note: It is a normal chemical process that white plastic turns yellow in direct sunlight.
