Patent ID: 8800860

Claim:
A method for cultivating plants, comprising: a) using an assembly for use in cultivating plants, comprising: a plurality of plant pots for use in cultivating plants, in which each plant pot comprises: a side wall ( 2 ), a bottom ( 3 ) and an open top, the side wall ( 2 ) and the bottom ( 3 ) delimiting an interior space ( 6 ) with plant material substrate ( 7 ) containing a plant, the bottom ( 3 ) having a bottom side ( 4 ) which is turned away from the interior space ( 6 ), the bottom ( 3 ) having a hole ( 15 ); and a reusable and removable tag located on a downward facing surface of the bottom ( 3 ), the tag provided with an optically readable code, the optically readable code readable by an optical read unit, located below the bottom ( 3 ), and directed upward at the downward facing surface of the bottom ( 3 ), the tag comprising a housing ( 12 ) in which a carrier ( 11 ) is accommodated on which carrier ( 11 ) the optically readable code ( 17 ) is located, a top side of the housing ( 12 ) of the tag ( 10 ) provided with a pin ( 13 ), the pin ( 13 ) being inserted through the hole ( 15 ) of the bottom ( 3 ) the tag ( 10 ) being hand-removable from the bottom ( 3 ) by grasping and pulling for reuse with another of said plant pots, the code of each plant pot is distinguishable from the codes of the other plant pots, and a computer system having a database in which the codes of the plant pots are stored and which database is designed for storing data for each code which are attributed to said code; at least one optical read unit for optically reading the code of one or more of the plant pots, which optical read unit is connected, or at least connectable, to the computer system for sending the read-out codes to the database; and a processing unit designed for attributing data to each said read-out code and storing data attributed to each respective read-out code with said code in the database; b) reading out the code of the plant pots by said at least one optical read unit; c) providing the processing unit with data relating to the plant that is grown in the plant pot, the code of which is read out in step b); d) sending the codes read out in step b) to the processing unit; and e) using the processing unit, storing the data obtained in step c) in the database with each code received in step d), wherein, the pin has a width greater than a height thereof, the pin has plural snap lugs ( 14 ) distributed over a periphery of the pin ( 13 ), the pin ( 13 ) is inserted through the hole ( 15 ) of the bottom ( 3 ) with the snap lugs ( 14 ) engaged with a top surface of the bottom ( 3 ).
