🔁 The HORT 450 - Controlled Environment Agriculture and HORT 410 - Urban Horticulture students visited the Freight Farms unit installed at University City High School in St. Louis.
🪴 🍕 They learned the ins and outs of operating a fully automated container farm and got some free pizza.

A month ago, at the Cannabis Cultivation and Science Conference in Bozeman, I had the chance to talk about how abiotic plant stress can modulate secondary metabolite responses and cannabinoid production. It was great to see how the cannabis industry in Montana is still collaborative. #thisissiu

Our graduate student, Rodrigo Raposo, dropped some serious knowledge about the establishment and maintenance of mother plants.
The HORT 482 - Cannabis Practicum students learned how to manage a mother plant room and create a checklist of activities for propagation in a cannabis growing facility.
