THC Yield and Greenhouse Cover Materials: Optimizing the Profit of Medical Cannabis

Abstract

Even though Delta-9-tetrahydrocannabinol (THC) is a psychoactive substance, studies indicate that it has therapeutic properties. Moreover, the modification in Greece legislation regarding the legalization of cannabis has resulted in new business opportunities for medical-cannabis related companies. This study aimed to evaluate whether different greenhouse cover materials affect THC yield and propose a business plan for any potential medical-cannabis related company in Greece. A greenhouse experiment was conducted in order to evaluate the effect of different plastic cover films in greenhouses for the cultivation of Cannabis sativa. Furthermore, the economic viability of a potential medical-cannabis related business in Greece was evaluated based upon a financial analysis. Yields were increased in greenhouses with double plastic cover materials (compared to the control). According to the results of our comparative economic analysis the production of medical cannabis in greenhouses constructed with double layered cover materials would significantly increase profits. Finally, greenhouse medical-cannabis production is much promising in Greece. Nevertheless, the use of appropriate greenhouse cover materials should be considered as they affect THC yield and therefore, the profit of the company.
