There are hundreds of cannabis seed varieties. There are so many cannabis varieties that no one can determine 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 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 best known 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 split into four main categories/species. These are:

• Indica
• Sativa
• Ruderalis

Indica Cannabis

Indica cannabis strains are typically small and dense. Well suited for the so-called "Homegrow", where you cultivate hemp at home in your growbox. Despite the fact that the plant becomes fairly small (about 1m), Indicas produce relatively many flowers. There are Indica Cannabis varieties that yield up to 600g per m² (about 4-5 plants). Indicas almost all come from Afghanistan, Pakistan, India, Tibet, Nepal, etc. so mainly from South Asia. The effect is primarily bodily 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 the wild, these can grow up to several meters high. The leaves are broad with many small fingers.

Ruderalis

The name comes from "ruderal", a term for a wild growing plant. Ruderalis is indigenous to Russia, Central Europe and Central Asia. They are very small, between 30-80 cm tall. The plant has few branches, but wide, bushy and light green fingers. As it has minimal THC content, it is seldom smoked but its genetics makes it very appealing for breeding.
