There are two different types of METRC tags, package and plant. METRC package tags are for groups of product or items so that they can be prepared for transfer or sale. METRC plant tags are only used by cultivators and help identify where plants are in their growth cycle.
If you log into METRC and then visit the Admin menu, you are able to notify METRC that you are ready to purchase your tags. For cultivators, you will need to order plant tags too. Keep in mind that you will need a METRC plant tag for every single plant you'll have at your facility once it reaches the required size or growth phase.
Upon delivery of your METRC tags, make sure you receive your new tags on your "Tag Orders" page in METRC. It is important that you complete this step and mark the tags as received in METRC before you start using them. You will first need your package tags to start your initial inventory. For cultivators, you will need to transfer seeds or clones to your license in METRC using package tags too. This step is timeboxed, so make sure you complete this step as soon as possible so you aren't rushing later or even too late.
Each item will have its own RFID-enabled METRC tag containing a Unique Identifier (UID) for that specific plant or package with a scannable barcode which can be used to find information like the facility growin the plant and cultivar information.
