Cannabis Sativa

CANNABIS SATIVA

Cannabsi sativa (= C. sativa var. sativa), originated predominately in asia, the Americas, and Africa. Each area of origin has specific characteristics, but all have the following general traits: tall, leggy stacture with spacious internodal length, a large sprawling root system, large narrow-bladed leaves, and somewhat sparse flowers when growing indoors under lights. Sativa bloom several weeks to months later than indica strains. While good productions outdoors, often growing to 15 feet (4.5m) or more, indoors pure sativa strains often grow too tall too fast some up to ten feet in three months-to be practical for grow room cultivation. An HID bulb is unable to efficiently illuminate tall plants, and the yield-per-watt-of-light or yield-per-square-foot-of-space is very low. Mexican, Columbian, Thai, and Jamaican strains can be very potent with a high THC to CBD ratio that produces a soaring, energetic, "speedy" high. But potency can also be mininal, with low levels of THC. Most exported Columbian, Mexican, Thai, and Jamaican marijuana is poorly treated throughout life and abused when dried and packed. This abuse causes more rapid degradation of THC consequently, seeds from fair smoke are often more potent than parent.

Central Africa sativas, including the THC potent "Congolese", grow similary to Columbian strains, with a tall leggy stracture often growing more than 15 feet (4.5m) tall with loosely packed buds.
South Africa has major seaports. sailors brought cannabis sativa from many different places and planted it in South Africa. Consequently, potency of South African weed can be very high or very low, and can grow short, tall, leggy, bushy, etc. The famous "Durban Poison" yields potent, pale green, early buds and is the best known South African strain.
Asian sativas, including Thai, Vietnamese, Laotian, Cambodian, and Nepalese, have diverse growth caracteristics and vary significantly in potency. While Thai and other sativas from the area are often super THC potent, they are some of the most difficult to grow indoors and the slowest to mature.
Thai strains produce very light, wispy buds after flowering for about four months on plants with large, sprawling branches. Thai, Vietnamese, Cambodian, and Laotain sativas are more prone to grow into hermaphroditic adults.

Nepalese sativas can grow oversized leaves on tall leggy plants that produce sparse, late blooming buds, but other strains from this region develop into short, compact plants that bloom earlier. Tetrahydrocannabinol (THC) production and potency is often quite high, but can also be second-rate.
Hemp strains are all considered to be cannabis sativa. Hemp, affectionately refferred to as "rope" is cannabis sativa grown for fiber content. Hemp is often seeded and contrains very,very low levels of THC.
