A light cover pot with no drainage hole, so keep the plant in its nursery pot inside and lift it out to water. Roughly right for a plant in a 14–16 cm nursery pot.

A ceramic cover pot for the same size of plant: heavier and calmer-looking than plastic. Measure your nursery pot's rim first; it should fit with a centimetre or two to spare.
