A recent UN survey indicates that 60% of Africans will live in a city by 2050.  The UN is concerned with where people will live.  We think this ties into questions of how they will get the food they need.

It's been a few months since graduation, and things have definitely been moving fast with VertiGrow!  We are currently working with XYZ design firm on our second round of prototypes, and are testing the new design this month.  Our homepage has been updated with some of the new designs, but we will continue to share our progress.  We're hoping to have our beta prototype in the field within the next few months.
