Self-watering wick
Polyester cord that carries water from the reservoir to the substrate by capillary action.
This is the one-euro part without which a self-watering pot waters nothing. The fibre sits in the reservoir and lifts water to the substrate at the rate the plant uses it: no pumps, no timers, no standing water.
It is polyester, not cotton or a natural fibre, and the whole difference is durability: a natural fibre sitting in water for months rots and stops wicking, polyester does not.
It also works in moss poles, where it brings moisture up from below instead of down from above.
The diameter sets the flow: 4 mm for pots up to 15 cm, 6 mm from 18 up.

How to use it
Thread it through the drainage hole leaving a few centimetres in the reservoir, and fray the end that sits in the substrate: more surface, more capillary action. Water from above the first time to prime it.
