This is probably already on somebody’s to do list, but it just occurred to me that with minimal effort, it would be possible to adapt the existing QR plant tag functionality to create labels for garden produce.
My intended use case here is for things such as punnets of fruit, bags of spuds etc.
These should probably be functionally identical to the plant labels, i.e. the QR code leads to the planting, but I could see them having pre-filled information about the location in which the item was grown, and hand-writeable (or printable) spaces for weight/qty, picked on (date) and best before (date). They should probably be sized and configured to print onto commonly available adhesive labels.
