Even traditionally "brown" thumbs can pull off a window garden when the planter fronts the work. Take this aquaphoric setup: Its steady supply of water means less stress for you and for your thirsty plants. (And a separate Veg Ledge can ensure a prime location for the greenery in your sunniest window!) A bargain all on its own, the $10 planter even comes with a pack of fiber soil to get you growing. Available on Amazon; $10.
