Rethinking Horticultural Practices in a Modern World

Urban environments present new agricultural problems that require new evidence-based solutions. To that end, we have joined with industrial partners to explore the effect of environmental controls (especially lighting) on yield of medicinal marijuana (Cannabis sativa) (TR1-3). For instance, we’ve discovered significant yield consequences (in both THC concentration and harvested biomass) when photoperiod is adjusted. To aid in the protection of crop breeding intellectual property and identify when transgenes have escaped domestication, we have invented a tool that can remotely detect small, incipient populations of flowering plants. Finally, urban agriculture has the potential to create increased food security for urban populations. We have invested significant effort in developing an agricultural system on Ryerson’s campus and measuring the horticultural practices of urban gardeners in our local GTA community.
