Engineers Without Borders group studies vertical farming to tackle food poverty

A group of students from the CMU chapter of Engineers Without Borders (EWB) has turned to vertical farming as a way to tackle food poverty. By experimenting with LED lights that flicker at different speeds, the group is attempting to find how much light is necessary to grow the biggest plant, using the least amount of energy.
