Cannabis Ruderalis

Little-known among consumers, ruderalis cannabis stands apart due to its growing characteristics and signature effects.
Author: John White

Discussions of marijuana strains are often dominated by debates about sativa versus indica, but most everyday consumers aren’t aware that there is a lesser known type of cannabis that carries specific characteristics that are particularly attractive to growers. That sub-species of marijuana is cannabis ruderalis.

What Is Ruderalis?

Cannabis ruderalis is a little-known kind of marijuana that is known for its ability to grow in conditions that would kill most cannabis plants. Ruderalis cannabis originates from Asia and Central/Eastern Europe – areas with climates too harsh for other cannabis species to survive.

Ruderalis seeds are incredibly hardy and can continue living even after they’ve been cracked open by being stepped on. They detach from the plant easily and can survive, dormant, in the frozen ground until conditions are favorable for the plant to grow.

The name ruderalis comes from the words ruderal or rudera, Latin terms that mean “rubble” in English. Ruderal plants are wild plant species that can flourish in land that’s been disturbed by human activity (such as construction) or natural disasters. It’s often found growing near roadsides or on farmland that’s been plowed and left unsown.

Many years ago, ruderalis grew wild, but today, breeders have harnessed the power of ruderalis to make hardy and spectacular hybrids.


Characteristics of the Ruderalis Plant

Ruderalis isn’t just more durable and hardy than sativa or indica plants; it also looks and behaves differently when grown. Here are the characteristics that set the ruderalis plant apart from all the rest.

Visual

Growers will find that the ruderalis plant is the smallest of all cannabis types, reaching a height of only 1 to 2.5 feet. The stocky little plants have thick stems and very wide leaves.

Buds

A ruderalis bud is generally smaller than those generated by other types of cannabis plants. Although they’re small, they’re sturdy and chunky.

Autoflowering

The autoflowering characteristics of the cannabis ruderalis plant is truly what sets it apart from sativa and indica species. Unlike the others (which must have their lighting manipulated in order to kick off the flowering process), ruderalis cannabis plants will automatically begin to flower between 21 and 30 days after being planted.

Harvest

A month or so after it begins flowering, cannabis ruderalis will be ready for harvest. Specifically, cannabis ruderalis is typically ready for harvest 70 to 110 days after the seeds are planted.


Ruderalis Effects

Pure ruderalis cannabis isn’t a species that will typically be found in a dispensary, so the only people who get to experience consuming it are those who grow it themselves. Ruderalis is known for the following effects:

No significant high

The extremely low levels of THC (tetrahydrocannabinol) in cannabis ruderalis means it doesn’t cause psychotropic effects. The fact that the species causes so little in terms of a high is part of the reason it’s rarely grown as a pure species and has largely been overlooked by recreational consumers.

Calming and relaxing

Its high CBD (cannabidiol) content makes it an excellent kind of cannabis for medicinal purposes. It’s especially good for medical marijuana patients who would like the benefits of CBD without the high of THC. Marijuana that is high in CBD is typically recommended for people with anxiety or insomnia due to its calming effects.


Breeding Cannabis Ruderalis Hybrids

Because there is no “ruderalis high” due to its low THC levels, ruderalis isn’t popular among recreational consumers – but it is of extreme interest to marijuana breeders. Most growers use ruderalis not as a standalone crop, but as an opportunity to create hybrids that contain ruderalis traits. Specifically, breeders value ruderalis because it’s an autoflowering sub-species that automatically begins to flower between 21 and 30 days, regardless of whether the grower manipulates the plant’s lighting.

The characteristics of ruderalis allow growers to create sativa/indica/ruderalis hybrids that contain potent levels of THC and will flower automatically.


Little-Known Species with Huge Power

Although ruderalis cannabis bud may not be among the offerings at marijuana dispensaries, most consumers don’t realize the impact that this little-known cannabis species has on their overall selection and experience. Using the power of cannabis ruderalis, growers are able to alter the genetics of their other strains – giving them autoflowering characteristics, boosting their CBD levels, and ensuring a hardier, more robust cannabis crop.

John, I think that what you have written about Ruderalis is incorrect. The CBD content is unknown, unless analysed. It has THC but in low dose. I have used male leaves and produced a wonderful healing oil, especially for insomnia. The seeds are not hardy, after 3 years they are rock hard and no attempts will breath life into them. Flowering occurs after 60-90 days, the female plant is about 600mm high, very petite and the male is 1.0 to 1.8m high.

I always thought hybrids were a mix of indica and sativa. I never heard of the ruderalis strain. Very interesting read, thank you.
