There are hundreds of cannabis seed varieties. There are so many cannabis varieties that no one can establish an exact number, as more are being bred. This is because the varieties are crossed with one another. Meanwhile you get every dubious cannabis seed variety offered, but they are all based on the same plant, the Cannabis Sativa. Cannabis varieties can vary in effect, price, cultivation, looks and other elements. Some of the most famous cannabis seed strains are certainly Crystal, Chronic, Big Bud, Ice, White Widow, Northern Light and Super Skunk. But there are numerous other cannabis seed varieties than only these.

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

• Cannabis Indica
• Sativa
• Ruderalis

Indica Cannabis

Indica cannabis strains are typically 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 flowers. 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 mainly from South Asia. The effect is more physical and makes you deeply relaxed, creating heavy sedation.

Cannabis Sativa

Sativa comes from the tropical regions. This variety continues growing during flowering, so Sativas tend to grow very large. In nature, these can grow up to many meters high. The leaves are broad with many small fingers.

Cannabis Ruderalis

The name comes from "ruderal", a term for an uncontrolled growing plant. Ruderalis is native to Russia, Central Europe and Central Asia. They are very small, between 30-80 cm high. The plant has very 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 appealing for breeding.
