That sounds like the sort of project that turns chaos into a living spreadsheet, which I can’t say no to. Start by giving every plant a unique alphanumeric ID—something like “G01‑R05” for greenhouse 01, row 05, so you can trace it back to the exact spot. Stick a small, durable tag on each pot, maybe color‑coded by species or growth stage, and record the tag number in a central ledger. For the digital side, a simple spreadsheet or a lightweight database with fields for ID, species, date planted, watering schedule, and last check‑in will let you sort and filter on any parameter. Use a QR code on each tag if you can afford a scanner; that way you can tap and pull up the full record in seconds. Once the system is in place, it’s a matter of keeping the ledger up to date—write it in as soon as you change anything. Trust me, the moment you stop guessing where that tomato vine was planted last week, you’ll wonder how you ever lived without a proper archive.
