Romulan is earthy, powerful, and easy to grow. Dense buds, nostalgic pine flavour, and a knockout stone bring full-body calm that soothes your limbs and quiets your racing thoughts.




Romulan is the kind of strain that quietly knocks your socks off. Heavily indica-dominant with a dreamy body stone and a whisper of sativa clarity, it’s a genetic throwback that still hits with surprising force. Expect pine-heavy old-school aroma, rock-solid relaxation, and an uncanny ability to slow things right down. Perfect for winding down after long days or tuning out the noise altogether. If you’re after something nostalgic, hard-hitting, and reliable in the grow room, Romulan delivers every time.
Romulan has always had a bit of mystique to it. Originally developed in British Columbia, this strain blends North American Indica genetics with White Rhino to create a cultivar with classic West Coast potency and deep physical effects. The White Rhino parent adds extra body to the already sleepy Romulan buzz, plus a little boost in resin production. It's a strain with roots in the medical scene, but plenty of appeal for anyone who loves that knockout, couch-ready kind of stone.
Romulan hits like a weighted blanket. It starts with a deep body calm, washing over muscles and joints before moving into a hazy, euphoric headspace. Sleep often comes soon after if you let it.
The flavour is pure throwback: earthy and woody on the inhale, with a spicy pine bite that lingers on the tongue. That pungent herbal kick is unmistakable, especially for fans of vintage indicas. And while it leans heavily toward the sedating side, there’s just enough happiness and cerebral lift to keep things enjoyable before the stone takes full control.
Romulan feminised seeds produce buds with around 20% THC and 0.5% CBD. It’s a well-balanced potency. Strong enough for experienced smokers to feel it, but not so overwhelming that you’ll forget your own name. Expect a steady, powerful high that lingers.
This strain's terpene profile is pure relaxation fuel. Alpha Pinene and Beta Myrcene give it that classic piney, earthy aroma, while Beta Caryophyllene adds a spicy, peppery note. Linalool and Limonene bring hints of sweetness and citrus behind the scenes. Alpha Humulene rounds it out with a faint woody bitterness. Together, these terps do more than taste good. They shape the calm, stony, contented high Romulan is known for.
Romulan is very beginner-friendly, especially for those growing indoors. Its structure is compact, its flowering time is reasonable, and it doesn’t demand much fuss. As long as you keep humidity in check, this one grows like a dream.
Indoors, Romulan stays compact at 80 cm to 120 cm, making it ideal for smaller tents or stealthy setups. Outdoors, it stretches a bit more (up to 200 cm) but remains manageable and predictable. Expect heights between 150 cm and 200 cm in a sunny garden. It performs well in Mediterranean and temperate climates, and can even handle continental zones when cared for properly. Greenhouse growers will also appreciate its steady performance and resilience.
Romulan flowers in 56 to 63 days indoors, delivering a solid 400 grams per m2 to 500 grams per m2. Outdoors, plants typically finish by early October in most regions, with yields ranging from 500 grams per plant to 800 grams per plant when conditions are dialled in. Buds are dense, resin-coated, and carry that unmistakable piney-funk aroma that makes trimming a joy (or a challenge if you're trying to stay focused).
