Although cannabis thrives in tropical and temperate regions, the advancements made within the industry have now allowed cultivators to grow cannabis virtually anywhere. For outdoor facilities, temperatures must be within the range of 65 degrees to 85 degrees Fahrenheit, while humidity should be within the range of 60% to 85%, according to Leafly. However, cultivators can manipulate these factors inside an indoor or greenhouse facility with greater ease. Generally, indoor and greenhouse facilities are equipped with modern technology that can control the temperature, humidity, airflow, and light strength in order to ensure superior growth. While the structure of an indoor facility can be quite costly, it allows cultivators to control the entire growing process leading up to the harvest. Additionally, different facilities tend to be better for certain strains. For instance, sativa strains grow better in tropical conditions because of their tall figure and more open bud structure. On the other hand, indica can be more difficult to grow because it is short and has denser buds, making it harder for airflow to pass through. Nevertheless, some sativas can grow short, while some indicas can grow tall, according to Pat Goggins, a former commercial cultivator in Oregon. Goggins notes it is important for cultivators to understand the genetic makeup of the plant so cultivators can provide optimal growing conditions for each specific plant. Some popular tropic-grown sativa strains are Colombian Gold and Maui Wowie, originating from Colombia and Hawaii, respectively. Colombian Gold and Maui Wowie can be grown both indoors and outdoors, however, there are certain strains that are grown solely indoors. For instance, Northern Lights is a popular indica strain for indoor cultivators because it needs steady airflow to prevent mold build up and it yields an abundant harvest. Regardless if cultivators grow cannabis in a controlled setting or an outdoor facility, there will be a consumer demand in both market segments. Some consumers may prefer a more potent strain grown within an indoor facility, while others may appeal to a more natural, outdoor grown strain. As a result, according to data compiled by Imarc Group, the North American legal cannabis market is expected to reach USD 35 Billion by 2023 from USD 8 Billion in 2017. Additionally, the market is expected to register a healthy CAGR of 28% throughout the forecast period. Pasha Brands Ltd.
