The buoyant plastic garden consists of a plank, grow space, plastic sheath, water tank, and pump that will feed and irrigate your seedlings as they bob on top of the water. The system relies on natural light provided by sun.

"By 2015, a projected 340 million people will reside in the worlds 21 megacities, of which 18 are coastal," says the group.

The groups recently won the core 77 Design Awards and have their modular hydroponic system in development for market release.
