Scientists Used This Rooftop Garden Hack to Help Plants Grow Significantly Bigger
Story by Tim Newcomb • 17m ago
Researchers used CO2 from classrooms at Boston University, through rooftop exhaust vents, to help spinach grow up to four times larger and corn twice as big than a control group not receiving CO2.
Higher temperatures near the exhaust fans may have also helped increase the growth of the plants, particularly the corn.
Researchers hope to create a system that can help bolster future rooftop farm installations.
The CO2-filled air in busy classrooms at Boston University was recently put to good use—as fertilizer for a rooftop garden, as part of a scientific study. Researchers repurposed the CO2 coming from a campus building’s exhaust to help grow plants in the experimental BIG GRO rooftop garden and found that spinach, in some cases, quadrupled in size compared to a nearby control group.
“We wanted to test whether there is an untapped resource inside buildings that could be used to make plants grow larger in rooftop farms,” Sarabeth Buckley, now at the University of Cambridge and the study’s lead author, says in a news release. “Creating more favorable conditions that increase growth could help make rooftop farms more successful and therefore more viable options for installation on buildings.”
sooo….. global warming=moar food?
