Practical Backyard Raft Hydroponics

Raft hydroponics is a very simple method of growing your own food in a limited space. Thanks to the power of educational websites and social media, inexperienced gardeners interested in exploring the various hydroponic growing techniques have a plethora of real world experiences to learn from.

Raft hydroponics is a very simple, passive form of soilless growing where plants float on a “raft”, typically consisting of a piece of styrofoam with holes spaced evenly across the surface, over a reservoir of hydroponic nutrient solution. The nutrient solution is often aerated through the use of an air pump and air stone, however, even without supplemental aeration, extremely impressive crops can be grown, making this method popular for use where electricity is not available.
