Grow Frame is a collapsible hydroponic farm that could grow vegetables inside shipping containers which normally make their return trip to Asia empty during the weeks-long sea voyage.

Grow Frame innovator, Philippe Hohlfeld, a design student says "This seemed a terrible waste of space. Half of all containers going to China are empty. And that means, right now, 13 million containers annually are travelling around with just air. And when I heard about that I thought 'no, that's not a problem, that's an opportunity."

Grow Frame can grow cabbages, spinach, lettuces, beans sprouts and mushrooms
