Tray agriculture is a method of crop cultivation that involves using trays or containers to grow plants indoors. This technique is growing in popularity due to its numerous benefits, including more efficient use of space and water, and easier control of pests and diseases. However, there are several synonyms for this practice that may be used interchangeably. These include micro-gardening, container farming, indoor farming, and vertical farming. Each of these terms refers to similar methods of growing crops in controlled environments using trays or containers. Regardless of the synonym used, tray agriculture is becoming an increasingly essential tool for agricultural production in regions with limited space and resources.
