At least where I live in Sweden we ain't getting enough natural light during the winter half of the year to grow small herbs for cooking, I've tried and have them sitting in clear view from the middle of a huge window (largest one I've got) and they still die, so I started putting them under some lights about 18 hours per day and they started not only regaining health but also accelerating in growth.

Now this wasn't any special light I just kept my kitchen CCFL's on and still saw some results however I've seen the results one can get with greater light system (especially paired with smart and learning control algorithms) as I've previously worked as a engineer/product developer on a light science company named Heliospectra were we could see amazing results not only in our labs but also at customers facilities.
