Watering is closely related to the health of plants. When planting in ordinary opaque flower pots and trays, many people do not know how much water is appropriate, which will cause plants to grow poorly in too dry or humid environments. PottIN’s styling is inspired by Chinese seals. It visualizes the amount of water through the transparent tray, which can present a seal-shaped pattern when there is muddy water as a sign of adequate watering. At the same time, it brings a pleasant watering experience to the users.
