- serissa
- tamarind
- murraya
- guava
- money tree
- orchid tree
- gardenia
- hibiscus

Optimum humidity 50-70% for plants such as:
- azalea

- pomegranate
- citrus
- lagerstremia

- cork oak
- cotoneaster

The tray should be larger than the pot with the plant, and its thickness 2- 6 cm.
Water is poured so that the bottom of the pot stood on the pebbles, not in the water.
Water is refilled as it evaporates.
This technique helps and outdoors (in hot weather and without wind.
Tray with wet stones does not replace watering, but only increases local humidity, thereby reducing the frequency of watering and spraying. Sometimes it saves the plant from drying out and overheating.
