Despite being little more than a weed, marijuana is an extremely complex and versatile plant, so we’ll forgive the newcomer or armchair enthusiast for being unable to identify different breeds and varieties by sight alone. Regardless of your personal relationship with cannabis, it isn’t necessary to know the difference between a Kush and a Skunk. A little knowledge goes a long way, though, if only to have something interesting to discuss among friends. Below, we’ll share some tips on how to identify your marijuana plants at a glance. 

Indica vs Sativa vs Ruderalis

Here’s a question for you – how many types of marijuana are there? If you answered three, ding ding ding! You’re correct. While there are literally hundreds of marijuana strains, they all descend from one (or a combination) of three main species: cannabis indica, cannabis sativa, and cannabis ruderalis. 

What’s the difference? From effect upon consumption to the physical structure and chemical makeup, quite a bit, actually. Let’s take a look. 

  • Indica: Cannabis indica originated in regions where the climate was colder and more unforgiving, as along the Hindu Kush mountain range that separates Pakistan and Afghanistan. Indica plants are shorter with broad leaves and tend to grow fast, offering a higher yield than their sativa counterparts. This probably has a lot to do with the shorter growing season in climates where the sun starts setting sooner (remember: marijuana is a photoperiod plant and needs the change in hours it’s exposed to sunlight in order to transition from the vegetative stage to flowering). 
  • Indica strains tend to be higher in CBD than THC, and have historically been used to promote physical and mental relaxation and to relieve pain, among various other effects. 
  • Sativa: On the other hand, Cannabis sativa originates in climates where the weather is humid and warm. These plants grow tall and lean, with thin, light green leaves. Sativa strains take longer to grow and require more light to reach their full potential. They boast higher levels of THC than CBD, and are prized for their ability to reduce anxiety and depression with their mood-enhancing qualities, increase focus and creativity, and energize the mind and body. 
  • Ruderalis: Of the three main varieties of marijuana, Cannabis ruderalis – or hemp – is the only one that we don’t consume. Sought after for its sturdiness (its strong fibers are used for textiles and products like paper, etc.) and naturally high levels of CBD, the plant is surprisingly small, most often only reaching about a foot though it can grow to about two and a half feet. It is bushy and rugged, with wide leaves and thick stalks, an evolutionary trait developed to counter the harsh and day-light stricken climate of its natural habitat. Often faced with grueling 24-hour daylight schedules, ruderalis automatically switches from vegetative to flowering after 21-30 days. Many breeders have taken advantage of this unique feature, combining ruderalis with indica or sativa strains to create autoflowering varieties of your favorites. 

The cannabis community has been poking around with genetics for decades now, and despite being popular in their own right, it’s relatively difficult to get your hands on “landrace” marijuana. seeds. Landrace refers to those marijuana strains that occur naturally in a single area and have not been cross-bred with any other strain. Back in the 60s and 70s, landrace marijuana strains were the only ones available on the market, but since then, breeders across the world have tinkered and toyed with different combinations, producing marijuana strains to suit every palate and need. 

Knowing what you know now, you’ll also be able to determine whether your plant genetics are dominated by indica or sativa based on their unique physical characteristics – talk about a cool party trick!

Male vs Female

There was once a time when marijuana gardeners would eagerly germinate marijuana seeds and patiently wait days and weeks and months for their precious beans to develop into fully budding cannabis plants. Imagine their disappointment when, after the investment of all that time and money (marijuana seeds do not come cheap), they end up with plants that don’t produce smokable buds (male) or their few female plants are pollinated by an errant male and start channeling energy into seed production and not the dense and resin-covered colas of their dreams. 

Thankfully, would-be growers of today are entering the fray at a time when cannabis consumers are demanding better quality and service from seed providers, and ordering online isn’t quite the game of Russin roulette it once was, but if you find yourself faced with a mixed bag, so to speak, you’ll be able to figure out pretty quickly once your seedling starts to take shape. 

Marijuana plants are dioecious, meaning they produce either male or female reproductive organs. Usually, by around the sixth week of the vegetative phase, you should be able to determine the sex of your plants by examining their “pre-flowers”: reproductive organs located between the nodes of the plant (where the leaves and branches connect with the stalk). Male plants will start with a pollen sac that will eventually spread pollen, and female plants have a stigma that will “catch” pollen released by males. identify-marijuana-plants

The pollination process works wonders for breeders who are interested in cross-pollinating different strains to produce something new, but for the average gardener just looking to maximize the return on their investment, it’s important to separate out any male plants before things get a little too familiar. 

  1. First of all, removing male plants from the grow space allows your female plants more room to grow and stretch their wings so to speak. 
  2. Second, when a male plant pollinates a female, some of the energy that would normally go towards beefing up a seedless cola (or sensimilla) where all that cannabis-rich residue is formed, is diverted to seed production. Buds of female plants that seed tend to be smaller, and are considered lower quality: when marijuana seeds are present in a smoke, the flavor is often unpleasant. 

Fact: It’s impossible to discern whether the marijuana seed in your hand is going to have balls when it grows up, but you can order feminized varieties of your favorite strains from reputable dealers like Pacific Seed Bank, which guarantees that your seed order will produce feminized plants.
