The case for outdoor growing: study suggests sun-grown cannabis may have therapeutic advantages

Cannabis grown under the sun tends to contain higher levels and a greater range of cannabinoids, has a richer terpene profile and produces far fewer carbon emissions than indoor cultivated plants, researchers have found in a new study exploring the clinical and environmental impacts of outdoor growing.

In a project commissioned by Foliumed, Dutch researchers analysed 39 cannabis strains from four peer-reviewed studies comparing outdoor grown cannabis to plants cultivated in heat and light-controlled indoor facilities.
