BSc, MSc and PhD students of universities worldwide are attempting to design a greenhouse or vertical farm, integrated in the city of Dongguan, China: an urban greenhouse. On 2 April, each team consulted six experts to discuss their plans and problems they ran into. Due to the corona crisis, this year the Urban Greenhouse Challenge organised its first ever online coaching session in the form of speed dates. Despite being in their own homes, both students and coaches were thrilled with the sessions. “The team really enjoyed the moments with the coaches. We definitely learned a lot!”, says student Camilla Grande Degaspari of team USP.
