Medicinal Cannabis Strains

Medicinal Cannabis Strains

The most popular varieties of Medicinal Cannabis are Hybrids resulting from a combination of C. sativa , C. indica , C. ruderalis and C. afghanica. On the Weediid website we have carefully explained the different types of seeds and their cultivation, but we are going to simplify it for beginners.

Traditionally, pure Indica Cannabis was cultivated for its medicinal effects, with little or no effect on the brain, and was best suited for outdoor cultivation. In Cannabis Sativa, on the other hand, the medicinal effects were minimal, but due to its higher THC content (Tetrahydrocannabinol), the psychoactive effects were much greater.

Today, the majority of seeds found on the market are Hybrids. Research in the cultivation of Cannabis has been aimed at producing plants more resistant to temperature changes, with faster flowering and higher production.

Cannabis S. Sativa

The Cannabis Sativa Sativa variety, or simply Sativa, is a subspecies of Cannabis Sativa. It comes from the equatorial zones of Asia, Africa and America. The pure varieties of C. sativa can reach 4 meters or more in their areas of origin. The leaves are large, with narrow leaflets. Its flowering is not very abundant but they bloom approximately in 3 months depending on the varieties and the environmental conditions of cultivation.

Due to its high proportion in THC it has mental and psychoactive effects. In addition, its consumption provides us with some medicinal benefits such as relieving nausea and pain, feeling of well-being and stimulation of appetite.

Cannabis S. Indica

Coming from Asian regions such as India, Tibet, Pakistan, Nepal, Morocco and Afghanistan, it is a plant with greater resistance to cold and arid and dry climates. It is easy to distinguish it from C. Sativa by its size: they are plants that do not reach more than two meters in height. They are more leafy and compact, and their leaves are darker green.

This variety contains more CBD than Sativas and a moderate level of THC, so its effect is more physical than mental and that means greater relaxation and sedation.  Its medicinal properties improve pathologies such as epilepsy, insomnia, anxiety, and it also has anti-inflammatory action, as a muscle relaxant and stimulates appetite.


A hybrid plant is the result of the cross between two or more races, varieties, species or genera. In cultivation it refers to plants that have been produced by man to obtain specific genetic characteristics.

Hybrids are often unstable in terms of passing on parental genetics to their offspring. This problem basically affects breeders and deserves a more in-depth chapter devoted to breeding.

The hybrid medicinal Cannabis seeds that we can find in the market are crosses of Cannabis S.Sativa with Cannabis S.Indica. Each cross has its own characteristics in terms of production, size and amounts of CBD (cannabidiol), depending on whether Sativa or Indica prevails.

In the 70s, the viability of crossing these with Cannabis S.Ruderalis began to be experimented, to obtain more resistant plants that did not depend so much on the photoperiod to flourish. At first the results were disappointing, because the plants had little production and flavor. Today the flavor has been improved, keeping the small size and resistance to the weather, and what are called self-flowering seeds have been obtained, which we will explain later in detail.

Cannabis S. Ruderalis is a wild variety whose origin can be found in Russia, Central Europe and Central Asia. They are small plants (between 30 cm and 80 cm). They produce few branches with broad, thick leaves. Its most notable feature is the ability to flower according to the age of the plant, regardless of the photoperiod (ratio of hours of light / darkness) in which it grows. This ability is known as auto flowering.

C.Ruderalis begins to flower between five and seven weeks of growth. Once it has started, it will continue until the cold causes the plant to die. This adaptation to fresh and short flowering periods means that its life cycle – from the time it is born until the flowers produce seed – is only approximately 12 weeks.

The wild varieties of C. Ruuderalis have a greater quantity of CBD than THC, which is very useful for their use in medicinal applications.
