Typical Appearance of Sativa Strains: Cannabis Sativa is normally a tall plant, and is generally a lighter shade of green than the other types. Its leaves are made up of long, narrow blades. Female flowers are longer and more ‘feathery’ in appearance than those of  Cannabis Indica. In general, the foliage of a Sativa plant is somewhat sparser than that of the other varieties. This allows for more air flow around and between the plants, resulting in healthier growth and less risk of fungus in humid tropical  conditions. How the Equatorial Origins of Sativa Strains Affect Their Growth Cannabis Sativa grows taller than the other types of cannabis, gaining height all through its growing and flowering phases. This is due to the tropical origin of Sativa strains. In the regions close to the equator, the length of day does not change very much throughout the year, so Sativa strains are adapted to accomplish both their growing and flowering in a short, fairly uniform photoperiod. In this way they are at the opposite end of the cannabis spectrum to Ruderalis strains. The female flowers of Cannabis Sativa start at the nodes (the points at which pairs of leaves grow from the stem and branches) and usually expand along the length of the stem and branches, instead of clustering around the nodes, as with the other types. This flower formation is due to the Sativa tendency to grow and flower simultaneously. As a result, female Sativa flowers are usually less dense and weigh less than Indica flowers, despite being larger in size. Cannabis Sativa Hybrids Pure strains of Cannabis Sativa often require a combined growing and flowering period of around six months to ripen completely. For this reason pure Sativa strains are rarely used for indoor cultivation or sold as commercial cannabis seeds. All Sativa strains that are viable for indoor growing have been cross-bred with Indica strains in order to reduce their height and flowering time. Even so, Sativa-Indica hybrids generally have a longer flowering period than their Indica relatives. Multiple Uses of Cannabis Sativa Nearly all hemp grown for industrial purposes is Cannabis Sativa. As the tallest variety, it produces the longest fibres and therefore has the widest range of industrial uses. As a recreational variety Sativa strains impart an energetic, cerebral and inspiring ‘high’, usually followed by a craving for food, especially sweet items, commonly known as ‘the munchies’. Although this aspect of the cannabis high is often the subject of jokes, it is also of life-saving importance when used by people undergoing chemotherapy, HIV/AIDS treatment and other procedures that cause nausea and/or lack of appetite. Cannabis Indica L. is generally agreed to have originated on the Asian subcontinent or possibly Afghanistan. Lamarck, the first European botanist to classify this type, received his samples from India and dubbed the plant Cannabis Indica in recognition of that fact. General Physical Appearance of Indica Strains The typical example of Cannabis Indica is a more compact, thick-stemmed bush than its cousins, usually reaching a height of less than two metres. The foliage is generally a dark shade of green, some examples appearing to have almost blue or green-black leaves. These leaves are composed of short, wide blades. Indica strains tend to produce more side-branches and denser growth than Sativas, resulting in wider, bushier plants. Indica flowers form in thick clusters around the nodes of the female plant (the points at which pairs of leaves grow from the stem and branches).  They usually weigh more than Sativa flowers of similar size, as they are denser. Growth and Flowering Cycle of Cannabis Indica The life cycle of Cannabis Indica is divided into two distinct phases – growing and flowering – which are reactions to different day-lengths (photoperiods). Growing occurs when the plant experiences long days and short nights, known as the long photoperiod. When growing, Cannabis Indica devotes its energy to increasing in size and stature. As days become shorter and nights longer (the short photoperiod), the plant receives the signal that winter is approaching and its flowering phase is triggered. In the flowering phase, upward and outward growth slows or stops as Cannabis Indica directs the bulk of its energy to growing reproductive parts – male flowers which distribute pollen or female flowers which produce the majority of cannabinoids and are meant to receive pollen and produce seeds. If male plants are eliminated early in the flowering phase, female plants are prevented from making seeds and their cannabinoid-rich flowers (also referred to as buds, tops or heads) may be harvested for medicinal and recreational use.  Indica strains require both a growing and a flowering period in order to reach their full size. Common Effects and Properties of  Indica Strains Most Indicas are a rich source of the cannabinoids THC, CBD and CBN. While Cannabis Sativa often produces a higher proportion of THC compared to its other cannabinoids, Cannabis Indica often contains significant levels of all three. Indicas tend to produce more body-centred effects than Sativas – enhancement of physical sensations, relaxation, dry mouth, red eyes. These effects are often grouped together under the term ‘stoned’, as opposed to the ‘high’ imparted by Sativas. This is not to say that Indicas have no psychoactive effect, just that they also have noticeable effects on the body. Cannabis Indica strains are cultivated almost exclusively for their medicinal and psychoactive properties, and may be the most commonly used medicinal marijuana strains. Lamarck, when classifying this type, commented that Cannabis Indica‘s « firm stem and thin bark make it incapable of furnishing similar fibres to the preceding species (Cannabis Sativa L.) of which so much use is made. » Cannabis Indica L. is generally agreed to have originated on the Asian subcontinent or possibly Afghanistan.
