Do you dread the coming of winter, fearing of the effect of so many dark days on living things that need sunlight to survive? This year, prevent a die-off by taking steps to prepare. One option: Simply move your most sensitive plants to a sunnier window. If there's no room left—or if none of your windows receive very much natural light this time of year—get a grow light! The OxyLED stands out, because on the one hand, it mounts easily, and on the other, its 360-degree adjustability means you can point the streamlined fixture anywhere you want. Available at Amazon; $24.99.
