Sativa is a more flowery strain of marijuana, it grows well where there is ample water. Of course sunlight too but this plant will grow as long as the sunlight stays above 12 hours a day! As with all plants it will grow until it sees the change in length of time the plant gets sun. Once it starts to flower it will be done in 8 to 12 weeks usually, dependent on the weather.
Sativa’s are just about the opposite of Indica’s. They are tall, thin plants, with much narrower leaves and grow a lighter green in color. They grow very quickly and can reach heights of 20 feet in a single season. They originally come from Colombia, Mexico, Thailand and Southeast Asia. Once flowering has begun, they can take anywhere from 8 to 12 weeks to fully mature. Flavors range from earthy to sweet and fruity. Sativa’s higher THC than CBD equals cerebral, soaring type of high, more energetic which can stimulate brain activity and may produce hallucinations. The buds are not as tight and compact as Indica.
Sativa plants are taller, take longer to mature, have less chlorophyll and more accessory pigments (accessory pigments protect the plant from excessive sunlight). As Sativa strains have less chlorophyll than Indica they take longer to grow, mature, and require more light.
Sativa typically takes longer to germinate and flower also, and grows more gangly then Indica breeds.
Yield is usually higher than Indica if it is allowed to mature, Thai Sativa grows taller and has a longer flowering period. If you grow a Sativa plant that is 10′ to 20′ tall, you better believe that the output will be large
The sativa high is often characterized as uplifting and energetic. The effects of a sativa marijuana are mostly cerebral. They give a feeling of optimism and well – being, as well as providing a good measure of pain relief for certain symptoms. A few pure sativas are also very high in THC content. They are known to have a quite spacey, or hallucinogenic, effect. Sativas are a good choice for daytime smoking.
