Because the high achieved with a pure sativa can sometimes include an irregular heartbeat or the unpleasant feeling of paranoia, smoking pure sativas is not as popular as other types of marijuana. That being said, sativas mix excellently with other strains to create a more perfect combination. Because properly bred hybrid sativas will exhibit the positive effects (the “up” feeling) on the user without the negative ones (the paranoia or irregular heartbeat), these strains are often preferred by those using it for medical purposes. They are particularly beloved for fighting depression and stimulating appetite. Many people choose to smoke sativa hybrids in order to take advantage of the very cerebral high. This type of feeling includes more energy and often a better flow of creativity. Like pure sativas, the actual plants will be on the taller and more slender side, with skinny leaves and a lighter green shade. Because sativas naturally have their origins in the tropical regions of the world, they thrive with a longer growing season. Hybrids that have mostly sativa genes are generally the same, so harsh climates are not ideal for outdoor growing. One of the greatest aspects of combining mostly sativa genes with partial indica is the fact that the plant will be a bit stockier and bushier and will have a shorter flowering time than pure sativas. Better yet, since the typical pure sativa yield isn’t particularly high, a combination with some indica genes also leads to a higher yield when it’s time to harvest. In other words, you get the effects of the sativa with some of the ease of growing an indica.
