Latitude And Flowering Onset

  • September 17, 2026 2:26 AM PDT

    Outdoor photoperiod plants start flowering when nights get long enough, and that moment depends heavily on how far north or south you live. Growers at high latitudes see flowering begin later in summer, which leaves less time before cold weather arrives. I compare the outdoor harvest months listed at https://budweedseeds.com with my local conditions rather than relying on flowering weeks alone. A strain rated for early September in Spain may finish noticeably later in a northern garden.
