Different Types of Cannabis Genetics


When browsing cannabis at a store, you’ll notice that they’re commonly broken up into strains—Indica and Sativa. Medicating with either of the strains produces different effects.

The Indica has a relaxant effect on the body and is often known as a sedative. It’s often used to treat medical conditions within the body such as anxiety, chronic pain and insomnia. The Indica strain is perfect for relaxing or as a nightcap before bed to aid sleep. Indica strains have a higher level of Cannabidiol (CBD), compared to Sativa, this may cause the feeling of relaxation, sleepiness or drowsiness and makes this the preferred choice for night time use, for many cannabis users.

Common Indica strains include:

  • White Widow
  • Northern Lights
  • Purple Kush
  • Chemo
  • Afghani

Sativa is the preferred choice of medication for many patients to use during the day. The Sativa strain contains higher levels of THC and provides an uplifting stimulant effect on the brain that can aid physical and social activity. The psychoactive properties of Sativa have an invigorating effect and can also boost creativity and decrease inhibitions. The properties within Sativa can also provide appetite stimulation, relief from depression and a boost in optimism.

Common Sativa strains include:

  • Durban Poison
  • Lemon Skunk
  • Blue Hawaiian
  • Big Bud

Pure Indica

Pure Indica seeds are sourced from hot regions of the world such as Morocco, Afghanistan, Tibet and Kashmir. The plants produced from pure Indica seeds are a deep green and dense, in comparison to its counterpart Sativa. The leaves are often easily distinguished because of their broad and round shape. It’s not uncommon for the leaves to turn a blue color, with hints of green and sometimes go a step further and transform into a deep purple.

Pure Indica has a shorter growing season than Sativa and the buds that pure Indica plants produce are larger and heavier size. It’s grown outdoors in regions that can sustain shorter growing seasons.

The relaxed feeling that pure Indica strains produce has a stronger effect on the body, as opposed to the brain. Medical cannabis users often describe the feeling as a type of hypnosis that completely relaxes the body.

Mostly Indica

Mostly Indica is a hybrid variety with genetics comprised of mostly Indica genes. The key difference between pure Indica and mostly Indica is the genetic traits in pure Indica are more predictable.

The mostly Indica plants are strong, shorter plants that bloom dense flowers. Certain qualities may vary, depending on the genetic makeup of the strain. When growing marijuana, Indica hybrids are popular because they’re easier to grow, in comparison to other varieties. The shorter growing season helps the plants to reach their flowering phase at a much faster rate when compared to other strains. A key benefit of mostly Indica is that it’s ideal for growing indoors, as they don’t grow vertically like Sativa and Sativa hybrids do.

The effects of smoking mostly Indica can leave a patient feeling sleepy and drowsy. Growers will often combine Indica genetics with Sativa to balance the two out and create a relaxing high.

Cannabis Hybrids

Crossbreeding Indica and Sativa strains produce a hybrid plant that contains attributes from both species of cannabis. The benefits of creating a hybrid can eliminate some of the side effects caused by a certain strain. For example, combining Indica with Sativa can suppress Sativa’s tendency to inhibit anxiety.

As opposed to using strains of pure Sativa, mostly Sativa, pure Indica or mostly Indica, medical cannabis patients can greatly benefit from the use of hybrid strains. They’re available with different CBD profiles, tailored to suit the patient’s needs.

Common hybrid strains include:

  • OG Kush
  • Jack Herer
  • Girl Scout Cookies
  • Blue Dream
  • Blue Widow
