The invention relates to a plurality of at least 1000 plant pots for use in cultivating plants. Each plant pot has a side wall and bottom which delimit an interior space for substrate which is open at the top, in which the bottom has a bottom side which is turned away from the interior space. Each plant pot is provided with a tag which has an optically readable code. The tag is arranged on the bottom side of the bottom, and the optically readable code is turned away from the bottom so that it can read from below when the plant pot is upright. The invention furthermore relates to an assembly with these plant pots as well as to a method for cultivating plants.
