There are hundreds of cannabis seed varieties. There are so numerous cannabis varieties that nobody can establish an exact number, as more are being developed. This is because the varieties are bred with each other. Meanwhile you get every questionable cannabis seed variety available, but they are all based on the same plant, the Cannabis Sativa. Cannabis varieties can vary in impact, price, cultivation, looks and other elements. Some of the best known cannabis seed strains are definitely Crystal, Chronic, Big Bud, Ice, White Widow, Northern Light and Super Skunk. But there are numerous other cannabis seed varieties than just these.

Cannabis varieties can be split into four main groups/species. These are:

• Indica
• Cannabis Sativa
• Cannabis Ruderalis

Indica

Indica cannabis strains are mostly small and dense. Well suited for the so-called "Homegrow", where you grow hemp at home in your growbox. Despite the fact that the plant becomes fairly small (about 1m), Indicas yield relatively many buds. There are Indica Cannabis varieties that yield up to 600g per m² (about 4-5 plants). Indicas nearly all come from Afghanistan, Pakistan, India, Tibet, Nepal, etc. so primarily from South Asia. The effect is more physical and makes you deeply relaxed, creating heavy sedation.

Cannabis Sativa

Sativa comes from the equatorial regions. This variety continues growing during blooming, so Sativas tend to grow very tall. In the wild, these can grow up to several meters high. The leaves are wide with many small fingers.

Cannabis Ruderalis

The name comes from "ruderal", a term for an uncontrolled growing plant. Ruderalis is indigenous to Russia, Central Europe and Central Asia. They are very tiny, between 30-80 cm high. The plant has few branches, but broad, bushy and light green fingers. As it has very low THC content, it is seldom smoked but its genetics makes it very interesting for breeding.
