TL;DR
Trays and pots provide physical support, drainage, and containment for growing media and plant roots. They are essential components of indoor, hydroponic, and soil-based growing systems, helping manage runoff, moisture, and root structure.
Pots are used to hold growing media and support plant roots, while trays and saucers collect runoff and protect grow spaces from excess water. Together, they help maintain clean, controlled growing environments and support consistent watering and drainage.
Trays and pots are used across soil, coco, hydroponic, and automated watering systems.
