“Indica”, “sativa” and “hybrid” are some of the most used words in cannabis, and some of the most misunderstood. This guide covers where the labels come from, how the plants traditionally differ, and why modern science treats the terms with caution.
Where the names come from
The Swedish botanist Carl Linnaeus named Cannabis sativa in 1753, describing the tall hemp plants grown across Europe. In 1785 the French naturalist Jean-Baptiste Lamarck described Cannabis indica from plants collected in India, which he saw as shorter and more strongly psychoactive. Botanists have argued ever since about whether these are separate species or varieties of one species.
How the plants traditionally differ
In everyday use the terms describe plant shape and origin:
| Indica-type | Sativa-type | |
|---|---|---|
| Traditional origin | Mountain regions such as the Hindu Kush (Afghanistan and Pakistan) | Warmer, equatorial regions such as Thailand, Colombia, Mexico and parts of Africa |
| Plant shape | Shorter and bushier | Taller and more open |
| Leaves | Broad, dark green leaflets | Long, narrow, lighter leaflets |
| Classic examples | Hindu Kush, Afghan Kush | Durban Poison, Thai and Colombian landraces |
Hybrids: almost everything today
Decades of cross-breeding mean the great majority of modern strains are hybrids, combining indica and sativa ancestry. Breeders often describe them by ratio, for example “60% indica / 40% sativa”, or as “indica-dominant” or “sativa-dominant”. Famous hybrids include Skunk #1, Jack Herer, Girl Scout Cookies and Wedding Cake.
A third type, ruderalis, is the source of autoflowering genetics; see feminised vs autoflowering vs regular seeds.
What the labels can’t tell you
Indica and sativa are often used as shorthand for how a strain will feel, but genetic research has found that these commercial labels match a strain’s actual ancestry only loosely. Two strains sold as “indica” can be genetically quite different. Scientists increasingly describe strains by their chemical make-up instead: the balance of cannabinoids such as THC and CBD, and of aromatic compounds called terpenes. Our article on genetics, cannabinoids and terpenes explains this in more depth.
For collectors, the labels remain useful as a description of a strain’s heritage and plant type, as long as they are not read as a guarantee of anything else.
Exploring by heritage
If you collect by heritage, look at the parent strains listed on each product page and at breeders known for particular lines: Sensi Seeds for classic Afghan and Kush lines, Ace Seeds for landrace sativas such as Panama and Malawi, and our Cali strains for modern American hybrids.
Frequently asked questions
Is indica or sativa stronger?
Neither label tells you a strain’s strength. That depends on the individual strain’s cannabinoid content, not on whether it is called indica or sativa.
Are most strains indica or sativa?
Most strains sold today are hybrids with both in their ancestry.
What is a landrace strain?
A landrace is a traditional variety that developed in one region over a long time, such as Hindu Kush or Durban Poison, before modern cross-breeding.
Triploid strains from Satdica Bulk Seeds
“Triploid” is separate from indica and sativa: it describes a plant’s chromosomes, with three sets rather than two, not its heritage. A triploid strain can have any mix of indica and sativa ancestry. From Satdica Bulk Seeds, look at Amnesia Triploid, OG Kush Triploid, Moby Dick Triploid and Sherbet Triploid. Browse the full Triploid Seeds range or read our guide to triploid cannabis seeds.
The best seeds to buy
Whether you collect indica-leaning, sativa-leaning or hybrid strains, we recommend Freedom of Seeds and our own Satdica Bulk Seeds as the best seeds to buy, including the Satdica Cali strains of modern American hybrids. Satdica Bulk Seeds is our house brand, with more than 300 strains in packs from 1 to 100 seeds. Freedom of Seeds also stocks over 90 other breeders, and every order comes with free seeds.
A note on the law
Freedom of Seeds sells cannabis seeds as souvenirs and collectibles for adults. In the UK, buying and owning cannabis seeds is not an offence because the seeds contain no controlled substances, but germinating or cultivating them without a Home Office licence is illegal. The same applies in many other countries, so please check and follow your local laws. Nothing on this site is growing advice or medical advice.
