Too many clear, and it’s not ready yet; too many amber, and the THC is beginning to degrade. Another good way to tell is if around 90% of the pistils on the flowers have turned red/brown. Linnaeus's flower clock was a garden plan hypothesized by Carl Linnaeus that would take advantage of several plants that open or close their flowers at particular times of the day to accurately indicate the time. According to Linnaeus's autobiographical notes, he discovered and developed the floral clock in 1748. It builds on the fact that there are species of plants that open or close their flowers at set times of day. He proposed the concept in his 1751 publication Philosop…
