Pure Sativa cannabis is a rarity in the medical marijuana field as these strains are a challenge to cultivate, especially indoors and outdoors in the northern hemisphere (Canada). Seeds of these types are also rare to find as vendors like to stock popular strains and pure Sativas aren’t that popular. Sativa’s come primarily from more equatorial regions (Colombia, Mexico and Southeast Asia). They grow as tall, thin plants, with narrow leaves and are light green in color. They grow quickly as compared to indica strains and can reach heights of 20 feet in a single season. Once flowering has begun, they can take anywhere from 10 to 16 weeks to fully mature. Flavors range from earthy to sweet and fruity.
Pure Sativa effects can often induce paranoia and irregular heart beats. Therefore, as a medicinal product pure sativas are a rare choice. If too much pure sativa is consumed it can have a similar feeling of drinking way too much caffeine.
The positive effects of sativas are their uplifting capabilities that may aid in depression, fatigue, appetite stimulation, pain and nausea. Sativas are the strains that were popular and readily available in North America during the 60’s and 70’s. Although pure sativas are quite rare, they are highly coveted by breeders who use their genetic stability to create designer hybrid strains.
