Pure sativa marijuana is well known for being difficult to grow, whether they are being grown indoors or in a northern outdoor location. They originate in more tropical areas of the world, including Mexico, South America, and Thailand. Despite this fact, they fare quite well in cold temperatures. Sativas are recognised by their height (the very tallest reaching 20 feet) and the fact that they are not as wide or bushy as indicas. Their leaves are equally slender and pointy, generally a much lighter green color than found in indicas. When the buds of a sativa plant get older, they often start to get red and then purple in color. If it’s the right type of strain it will even become yellowish or gold in color. When you smoke a pure sativa, you can expect a flavor and smell that is sweet, fruity, and spicy. People who particularly enjoy a high that instills them with energy will prefer sativas over other strains (especially indicas) because it infuses smokers’ brains with energy and a feeling of uplifting. Marijuana from sativa strains are often recommended for the treatment of depression, ADD, mood disorders, or fatigue. Because sativas grow taller than indicas, they are better for outdoor grow setups than indoor ones, but are hard to grow in the north. This is because, once they begin to flower, they likely need between 10 and 16 weeks just to reach maturity. Generally speaking, sativas are far rarer than indicas, but they are prized by growers looking to create effective hybrids.
