Cannabis Classification

Cannabis Classification Cannabis (Family Cannabaceae) The genus Cannabis (Family Cannabaceae) is likely to have originated in the wet habitats of Asiatic continent. The long coexistence between mankind and Cannabis led to an early domestication of the plant, which soon showed an amazing spectrum of possible utilizations, as a source of textile fibers, as well as narcotic and psychoactive compounds. The early domestication of Cannabis has lead to many specialized plant uses that fall into two main categories… Fiber Chemical compounds Breeding continues for increasing diversity and specificity Cannabis is Dioecious Produces distinctive male and female plants. Each plant from the point that is an embryo is genetically either male of female this is visually identifiable by the flowers the plant will produce. In some isolated cases plants will produce both male and female flowers and can called hermaphrodites With chemical treatments it is possible for a female plant to produce pollen. Vernacular “Sativa,” “Indica,” and “Ruderalis” The development of vernaculars “Sativa,” “Indica,” and “Ruderalis” that are commonly used was against the recommendations by twentieth century botanists Instead personal cultural biases prevailed and so did the use of these terms. Four Main Classifications of Cannabis Classification is based on Morphology not Physiology Morphology = the study of the size, shape, and structure. Physiology = relating to the function of an organism, and how they respond to challenges. To predict potential effects the Cannabinoids and Terpenes (chemical profiles) should be identified Each plant morphology grouping has its own general advantages and drawbacks… Sativa General Characteristics: Tall growing (typically 4-15ft.+) Internode spacing of 3-6” Leaves are long and thin Advantages: High biomass producers Commonly grown outdoors Produces better in climates with a long warm season Drawbacks: When grown outdoors can be more susceptible to wind damage Can have increased time to flower and mature compared to other options Photoperiod dependent Indica General Characteristics: Small plants growing to 1-6ft tall Internode spacing typically 3” or less Wide leaves morphology Advantages: Can be a better fit for indoor growing operations where celling height may be limited Shorter flowering time can allow for more plant cycles for indoor grows Often have a quicker flowering time than a Sativa Performs well in colder climates that have a shorter growing season Drawbacks: Limited total biomass produced Photoperiod dependent Ruderalis (Autoflowers) General Characteristics: Tend to be small plants in the 1-3ft range Tight internode spacing with frequent branching Leaves are small and wide Advantages: Photoperiod Independent Plant life cycle is based on a set number of days Currently limited options in this category Drawbacks: Tend to be smaller plants which can mean less yield Typically produce less cannabinoids and terpenes that other options A day lost is a greater portion of the total life cycle of the plant Hybrids *Many current plants are actually hybrids due to the secretive (and often unknown) breeding that has occurred.
