"The Tonight Show" was first seen on this day in 1954 and ever since has been the annual winter entertainment for gardeners who pack it up and hibernate indoors for the winter. There are those who keep their thumbs green all fall and winter, basking in the health glow of grow lights. For those without south-facing windows, a ship light with two fluorescent tubes, one cool spectrum, one warm, is an inexpensive answer. Others use high-intensity lamps or halide lights, which are good for growing everything from seedlings to mature vegetables. Sodium lights grow mature flowers and fruit plants. And that's the On The House tip for today.
