Self-Watering Tray G140 / G70

Simple and effective. The base is a black water tray (sometimes shown in green) measuring 40x56 cm, which can hold over 3 litres of water. A raft on legs is placed in the tray, over which a supplied water-absorbing mat is fitted, with part of it hanging into the water below. Seed trays (make sure they have holes) or pots can be placed on top, providing 1-2 weeks of automatic watering! The tray fits perfectly into the plant solarium (809390), and one is already supplied with it.
