T he cannabis industry, like other agricultural industries, is undoubtedly dominated by hybrid varieties. Through selective breeding, humans have been able to fine-tune hybrids to contain desired genetic traits. For cannabis plants, these desired traits can range from unique cannabinoid profiles, such as varying levels of THC and CBD, to having certain flavor or aroma characteristics influenced by specific terpenes. Hybrids can even be bred to display higher tolerances to things like drought or disease when the proper cultivars are used in the breeding process. The vast majority of hybrid cannabis available today is usually a mix of both indica and sativa species that are often bred to contain more dominant traits from one, such as a sativa-dominant strain. Cannabis is widely believed to have first evolved in Central Asia, and as migrants and traders traveled to other regions, they would often carry cannabis seeds with them. These seeds would then be planted and cultivated in a dif- ferent environment from which they came. For thousands of years, these plants interbred in different regions without the interference of other cannabis varieties. This caused them to adapt to their environments. In doing so, they developed distinct genetic traits and characteris- tics unique to their respective homes. Such plant varieties eventually became indigenous to their individual regions and are now referred to as the landrace strains. They are the genetic forefathers of modern hybrids and many popu- lations are still maintained today. This is where the terms indica and sativa come into play. These two varieties are the main landraces that modern hybrids stem from. The cannabis that was introduced and allowed to breed in the mountainous regions of Af- ghanistan, Pakistan, and India are called indicas. In these regions, the growing season is shorter and the weather can be harsh at times. Indica has adapted by growing shorter and bushier, and flowering a bit earlier in the season once summer solstice brings longer nighttime periods. Sativas, on the other hand, originated in areas closer to the equator like southern Asia and northern Africa. Since the weather stays warm year-round there, cannabis sativa plants will grow taller and leaner and take longer to flower. myhydrolife.com A third, lesser known landrace variety is cannabis ruderalis. Ruderalis evolved in the Siberian region of Russia, where the growing season is notably shorter. This variety grows much smaller than its indica and sativa cousins and has a significantly lower level of THC and other cannabinoids. What makes ruderalis unique from other landraces is the fact that it flowers upon reaching a certain point of maturity and does require a change in photoperiod length. This allows it to flower more quickly, giving the plant variety a level of importance among breeders. “ Such plant varieties eventually became indigenous to their individual regions and are now referred to as the landrace strains. They are the genetic forefathers of modern hybrids and many populations are still maintained today.” The original landrace indicas and sativas, and their individ- ual traits, are often named for the places they originated, such as Afghani, Hindu Kush, Malawi, or Thai. Throughout the 1970s, cannabis aficionados from around the world traveled throughout Asia, Africa, and the Middle East in search of the best of what they viewed as a sacred plant had to offer. The routes they followed are part of what is called the Hashish Trail, aptly referred to as the Hippie Trail. On their journeys, many would collect seeds from landrace cannabis varieties and bring them home to grow in their own gardens, effectively making them heirlooms. The relevance of this strain relocation in the US lies mostly in Hawaii and the hills of northern California. Northern California’s Emer- ald Triangle sits approximately on the same parallel line as Afghanistan and the Hindu Kush mountains. Indica varieties found themselves right at home in northern California’s cooler climates and shorter growing seasons, eventually giving birth to the famous OG Kush variety. grow. heal. learn. enjoy. 73
