i bought these a couple of years ago. my plants are on shelves w/ lights, and i place one of these cards on each shelf, and noting what day that shelf was last watered. if one on the watering shelf doesn’t need water yet, i transfer it to another shelf to be checked in a few days. https://a.co/d/06bzLPMB
