College Times:  “GreenHorizons University (1410 N. Scottsdale Road, Scottsdale) opened its doors May 15, teaching class-goers how to grow and cultivate medicinal marijuana. However, students won’t be handling the plant itself. Instead, students of Green Horizons University will grow tomatoes, thanks to their similar growing process and cycle.  In addition to hosting the grow school, Green Horizons is also a hydro store.”
