3- Pots, plant pots and planters with water supply

Particularly suitable for plants that appreciate humidity, these containers have a double bottom in which there is a reserve of water with an autonomy of up to 12 weeks. The water brought in when filling the pot is returned to the plant by capillary action. Separation from the earth is achieved by means of a grid or a pierced tray. A gauge is sometimes used to estimate the level of water in the reserve. In case of rain, the excess water drains through an overflow. In some cases, it may be necessary to put a drainage layer at the bottom of the pot.

Battery life: up to 12 weeks

Tank capacity: up to 27 L

Since its systems operate at low pressure, it may be necessary to connect a pressure reducing valve to the water inlet.
