I just LOVE Ikea. This May 2016, they are launching Krydda/Växer, an indoor gardening series. In a pure Ikea fashion, all you need is included to grow your own lettuce or herbs; all year round. It works thanks to the simplest elements of all: water. The technical name is Hydroponics: growing plants in water without soil. Coupled with nutrients and the right light, you can grow your own veggies in any small space.
