Trough - Flowerpots

A trough is a shallow basin-shaped container, usually made of metal or wood, used to transport water, feed, or building materials.

Troughs are often used on farms to feed animals, but can also be used on construction sites to mix concrete or transport tools and materials. Troughs can vary in size from small portable troughs to large fixed troughs that are anchored to the ground. Diverted the trough serves as a basin or flower tray.
