Self watering plant trays have capillary matting. You water under your pots and your plants then drink at their own rate.

If you are enthusiastic watering, the trays catch the overrun, and gradually release the water, saving work and mess.

You can even go a few days without watering.

Supplied are 5 self watering trays complete with capillary matting to put under your pots or trays of pots.

The trays each hold 53cm x 28.5cm (21in x 11.2in) of pots.
