Key specifications

Romulan strain: origin and name

The Romulan strain is a North American indica line with a long history — originating in Canada and named after the Romulans, the legendary alien race from the Star Trek saga. The name says it all: like the Romulans of the science-fiction universe, this strain is known for its strength, intensity and unmistakable character.

Pyramid Seeds has feminized and stabilised this classic North American genetic — keeping strain purity, a consistent terpene profile and the characteristic violet-red flower colours that make Romulan one of the most visually exceptional indica strains in the catalogue. Romulan Pyramid Seeds — sometimes called Purple Romulan for its colouring — is the original feminized version of this Star Trek namesake.

Violet-red flowers: why Romulan gets its colour

The unusual violet and reddish tones come from the activation of anthocyanins — colour pigments in the plant that respond to cooler temperatures. In late flowering, night temperatures below 18–20 °C cause the flowers to develop their cosmic shades.

This colour development is purely visual — it affects neither THC content nor effect, but it boosts bag appeal and makes a Romulan harvest a real showpiece.

Romulan strain effects

The Romulan effect is strongly indica-led — powerful, long-lasting and sedating:

• Euphoria — an elevated mood and cerebral lift at the start
• Deep physical relaxation — muscles relax completely
• Stress relief — mental tension and anxiety dissolve
• Calming — promotes inner calm and serenity
• Evening and night use — sedating and sleep-promoting at higher doses

Aroma and terpene profile

Romulan has a classic North American indica profile: dominant pine resin (pinene), sweet accents and spicy notes with a warm, long aftertaste. Dense, resin-rich flowers with an intense, long-lasting aroma.

Growing — indoor and outdoor

Indoor growing

Flowering time 43–53 days under LED (HPS: 50–60 days). Yield: 450 g/m² standard, up to 750–850 g/1.5 m² with a 720 W LED. LST and SCROG recommended. For violet-red colouring: lower the night temperature to 16–18 °C in the final flowering week. Good air circulation matters.

Outdoor growing

Harvest in September in the northern hemisphere. 750 g – 1 kg per plant. Cool autumn nights naturally encourage the violet-red colouring — no extra intervention needed.
