Romulan is an indica-dominant cannabis strain with sedating, tranquilizing and narcotic-like effects. Reports suggest that Romulan could help manage chronic pain, insomnia, and appetite loss. Its candy, earthy, pine, and citrus flavors create a refreshing overall experience.

These days, Romulan contains 75% Cannabis indica and 25% Cannabis sativa genetics. However, it was initially believed to be a 100% pure indica strain. Romulan’s parent strains aren’t entirely known, but White Rhino (an indica strain) is one, and the other is likely to be a type of North American indica cannabis strain.

Next Generation Seeds initially produced Romulan, and it’s thought that a breeder called Romulan Joe was influential in creating this strain.

In terms of its appearance, Romulan produces dense and frosty buds. It has brightly colored brassy-orange pistils that can be found between the bright green sugar leaves, with frosty buds that are packed tightly together.

Romulan gets its name from the fictional Star Trek alien species with ridges on their forehead and pointed ears. People have joked that when using Romulan, you could “dent your head” because it is so strong.

The Romulan strain is well-known and mentioned in Skunk, High Times, and Cannabis Culture. It also won third place for Best Non-Solvent Hash in the 2017 High Times Medical Cannabis Cup.

growing strains

Romulan can be grown indoors and outdoors, and it’s relatively easy to grow and manageable for novice users.

Romulan is resistant to many diseases, insects and mold. Because of this, it doesn’t require as much maintenance as some other strains do.

The Romulan strain has a similar yield when grown indoors and outdoors. You can expect a yield of about 9 ounces (255 grams) of bud per square meter.

Romulan is a stocky plant that grows many branches. This means that the “Sea of Green” (SoG) method (growing many small cannabis plants in a limited space) and the “Screen of Green” method (growing cannabis plants through a horizontal screen) are both suited for the Romulan strain.


Although the Romulan strain is relatively short, it often grows taller than other indica-dominant strains. It’s essential to ensure that it has enough space to branch up and grow upwards.
You can expect Romulan to reach heights from 60 to 80 inches (approximately 1.5 to 2 meters).

Humidity and Temperature

Romulan plants grow best in a sunny, warm, and dry environment. A Mediterranean-like climate is described as being optimal for growing Romulan.
Temperatures between 68 and 78 degrees Fahrenheit (20 and 26 degrees Celsius) are suitable for growing Romulan.


The average flowering time for a Romulan plant is eight to nine weeks. If you grow Romulan outdoors, you can expect it to be ready to harvest in mid-October (in the Northern Hemisphere).
