The cannabis plant is versatile, hardy, and—unlike many kinds of plants—can survive in almost every climate in the world. However, thanks to evolution (and later on, selective breeding), the species has adapted to the landscapes in which it’s cultivated, and thus, vast variation between different cannabis plants is the norm today.


There are thousands of unique cannabis strains, and each has different characteristics that impact growth, production potential, flavour and aroma, and physiological effects on people. Yet, all of these strains can be grouped into one of three cannabis subspecies: Cannabis sativa, Cannabis indica, and Cannabis ruderalis.

The vast majority of photoperiod strains (strains that initiate bloom based on a change in light cycle) contain varying amounts of both indica and sativa genetics. Ruderalis, on the other hand, is a type of autoflowering cannabis that flowers based on age, and is often considered to be inferior to photoperiod cannabis morphologically. Although there is more to say in this regard, for the remainder of this article, we will be focusing mainly on the distinct characteristics of indica and sativa so the average grower can get a better idea of what to expect.


Cannabis indica is indigenous to today’s regions of India, Pakistan, Turkey, and Afghanistan. Originating in the harsh and varied environments of the Hindu Kush mountains, these stocky bushes develop wide, dark green leaves to soak up all available sunlight, flower quickly, and produce a plethora of dense buds.


Thanks to the short growing cycle offered by indicas, not to mention their short stature, they can be quite convenient for home growers without too much time, space, or resources on their hands. Just think about it; a compact bush that finishes fast is easier to maintain (especially indoors) than a spindly, albeit majestic, tree. Even outdoors, indicas are resilient and laugh in the face of fluctuating temperatures—just remember where they came from. Moreover, the fast flowering time of indicas means outdoor growers can harvest before the first frost.


Although indica plants normally develop into a Christmas tree-like shape, this growth can be tamed and manipulated to even out the canopy and direct more light to all available budding sites. Techniques like topping and basic LST (low-stress training) can be used to give your plant the ideal shape for robust health and huge yields. Once you’re happy with how it looks, you can switch your vegging plant to the flowering phase by reducing light hours inside to 12 hours on, 12 hours off.

One of the major “drawbacks” you must watch out for with indicas is also one of their greatest strengths: dense buds. Indeed, as buds grow in size and put on weight, they become at much greater risk of developing mould, especially in humid regions with temperatures that foster pests and pathogens. Avoid this issue by carefully controlling environmental conditions inside, or by erecting necessary shelter outside (in case of rain, excess humidity, etc.). Having a small greenhouse or shed where you can hide your plants from inclement weather can be a great safety net.


• Short, bushy stature
• Broad, dark green leaves
• Dense buds
• Short flowering time
• Resilient to temperature fluctuations
• Susceptible to mould and pests

Cannabis sativa is found mainly in the hot, dry climates of Africa, Asia, and Central America. These strains grow into tall, slender specimens with long, thin leaves. As they can exceed 3m in height, Cannabis sativa typically takes much longer to mature than indica.


Sativas require a lot of light and higher temperatures to thrive—just think about their natural habitat located relatively close to the equator. These plants also require a large amount of space, have much airier buds, and remain in the flowering phase for several weeks longer than most indicas. In their favour, these plants usually require less fertiliser and fewer feedings than indica plants. Moreover, thanks to their airier bud structure, flowers are less susceptible to mould and excess moisture.


Sativa plants can be delicate, and have less chlorophyll than indicas due to their thin leaves. This also means that you need to give your sativa plants sufficient light, heat, and humidity. Whereas you might be afraid to raise your indicas in the tropics, your sativas will be right at home in the warm, sticky weather.

For those with a bit of growing experience, you can tame the height of your sativa specimens using the screen of green (ScrOG) technique. By situating a screen above your plant and weaving new growth through the mesh, you’ll create a flat canopy of buds that optimises available space and yield potential. Like indicas, regular (photoperiod) sativa varieties require a change in light cycle to start blooming. Keep in mind that plants can continue to surge in height for the first couple weeks of the flowering phase, so make sure you have the space to accommodate this growth spurt.


• Tall, lanky stature
• Thin, light green leaves
• Airy buds
• Longer flowering time
• Requires higher temperature and humidity
• Less susceptible to mould

While you can find 100% indica or sativa strains, most cultivars on the market today contain varying levels of both genetics. As a result, these “hybrid” strains can be indica-dominant, sativa-dominant, or split 50/50. This versatility allows breeders to create novel strains that harness the best features of both sativa and indica while eliminating the less advantageous features. For instance, a well-developed hybrid will feature the dense bud structure and short flowering phase of an indica, combined with the best traits of a given sativa to offer the best of both worlds.

Remember the ruderalis subspecies we referred to earlier? Hybrids can contain these genetics as well, although, as mentioned above, ruderalis is chiefly added to reduce flowering time since its other qualities are seen as inferior. Some photoperiod cannabis strains can contain a small amount of ruderalis, but these genetics mostly reside in autoflowering strains.

Typically, hybrids will inherit the easy growth of indica plants while keeping the highly sought-after effects offered by sativas. As such, hybrids have become the go-to for home growers and commercial cultivators alike.


• Takes morphology from both indica and sativa
• Generally brief flowering time
• Great yields
• Robust and resilient growth

Enjoying a successful harvest starts with understanding the nuances of growing indica vs. sativa cannabis plants. Come inside to find out the essential basics.

Cannabis Indica

Cannabis Indica L. is generally agreed to have originated either on the Asian subcontinent, or possibly in Afghanistan.

French naturalist Jean-Baptiste Lamarck, the first European botanist to classify this type in 1785, received his samples from India and dubbed the plant Cannabis Indica in recognition of that fact.

Types of Cannabis

General physical appearance of Indica Strains

The typical example of Cannabis Indica is a more compact, thick-stemmed bush than its cousins, usually reaching a height of less than two metres. The foliage is generally a dark shade of green, some examples appearing to have almost blue or green-black leaves. These leaves are composed of short, wide blades.

Indica strains tend to produce more side-branches and denser overall growth than Sativas, resulting in wider, bushier plants. Indica flowers form in thick clusters around the nodes of the female plant (the points at which pairs of leaves grow from the stem and branches). They usually weigh more than Sativa flowers of similar size, as they are more solid.

Growth and flowering cycle of Cannabis Indica

The life cycle of Cannabis Indica, like the rest of the Cannabis genus, is divided into two distinct phases – vegetation and flowering – which are reactions to different day-lengths (photoperiods). Vegetation is also sometimes referred to simply as the growth, or growing, period, although the plant continues to grow in size and mass throughout the flowering period as well.

Vegetation occurs when the plant experiences long days and short nights, known as the long photoperiod. When growing, Cannabis Indica devotes its energy to increasing in size and stature. As days become shorter and nights longer (the short photoperiod), the plant receives the signal that autumn is approaching and its flowering phase is triggered.

In the flowering phase, upward and outward growth slows considerably and may appear to cease completely as Cannabis Indica directs the bulk of its energy to growing reproductive parts – male flowers which distribute pollen, or female flowers which produce the majority of cannabinoids and are meant to receive pollen and produce seeds. If male plants are eliminated early in the flowering phase, female plants are prevented from making seeds and their cannabinoid-rich flowers (also referred to as buds, tops or colas) may be harvested for recreational and medicinal use.

Common effects and properties of Indica Strains

Most Indicas are a rich source of the cannabinoids THC, CBD and CBN. While Cannabis Sativa often produces a higher proportion of THC compared to its other cannabinoids, Cannabis Indica often contains significant levels of all three. Indicas tend to produce more body-centred effects than Sativas – enhancement of physical sensations, relaxation, dry mouth, red eyes. These effects are often grouped together under the term ‘stoned’, as opposed to the ‘high’ imparted by Sativas. This is not to say that Indicas have no psychoactive effect, just that they are more renowned for their noticeable effects on the body.

Cannabis Indica strains are cultivated almost exclusively for their medicinal and psychoactive properties, and may be the most commonly used medicinal marijuana strains. Cannabis Indica’s firm stem and thin bark make it unsuitable for fibre production.
