One week after an unusual bout of steady rain for several days, the plants were wild with growth. The radish leaves hung over the sidewalk, begging to be cut and pickled into kimchi. The red lettuce was plenty for salads and wraps. The kale and chard were robust, and the mint quickly took over its part of the land. I was most surprised though that they seemed to grow exponentially at night- without sun and without any human help.
