With limited spaces for gardening in cities, many urban apartment dwellers have sought alternative ways to grow their own food. Enter the ever innovative, window farm! With a large enough window and some DIY spirit, growing everything from herbs to tomatos to strawberries is possible.

All you need to get started are some plastic pop bottles, hardware store tubing, clay pellets and some cheap pumps typically used in aquariums. To get started, everything will run you around $30. Oh, and you’ll need some guides along the way!

Window farming is built on technology that’s open source, so anyone can use, modify and replicate it. The community is widely supportive and informative. This basic guide is a good place to start.
