Romulan
Romulan is the Canadian indica originally developed by Mighty Mite Seeds in British Columbia during the late 1970s from an unnamed North American indica selection, and the name was kept as a tribute to the Star Trek species when the working line entered commercial circulation through Federation Seeds in the 1990s. DNA Genetics released a refined seed-form selection in the 2000s working from a verified Romulan cut, locking in the dense bud structure, piney earth terpene profile, and heavy indica high that long-time BC growers associated with the original. The plants finish in roughly eight to nine weeks indoors with squat, branchy structure and good resin coverage, and the high is one of the heaviest sedative indica profiles in the Canadian-origin canon. Romulan crosses including White Romulan, Romulan Grapefruit, and Romulan Haze are common in West Coast and BC breeding work, often used to add indica weight to sativa-leaning hybrid projects. The DNA release is the most reliable seed-form source for growers outside Canada looking for an authentic Romulan working line.

Terpene profile
The aromatic compounds below shape how Romulan smells, tastes, and ultimately feels in the body.
- dominant
Pinene
Alert and pine-forward — associated with mental clarity and bronchodilation.
- secondary
Myrcene
Sedating, musky, herbal — commonly linked to couch-lock effects.
- secondary
Caryophyllene
Peppery and spicy — the only terpene that binds CB2 receptors, studied for anti-inflammatory action.
- minor
Humulene
Hoppy and earthy — appetite-suppressing and shared with hops and sage.

Lineage
Romulan traces to North American indica (unnamed BC selection). The cross sits in the Canadian indica family, which influences both the terpene profile and the flowering structure described above.

Feed schedule for Romulan
These EC and NPK targets are starting points calibrated for the strain's Indica lean and moderate difficulty rating — not gospel. Drop 15-20% off any EC ceiling on your first run and let the plant tell you where it actually wants to feed.
Suggested feed schedule
- Late veg
- 1.4-1.6 EC
- Early flower
- 1.5-1.7 EC, NPK 2-3-4
- Mid flower
- 1.8-2.0 EC, NPK 1-4-6
- Late flower
- 1.6-1.8 EC
- Final week
- Plain pH-balanced water for the last 7-10 days; light flush if you ran nutrients on the higher end.

What to expect through the grow cycle
Romulan is documented with a 9-week flower and a compact stretch typical of indica-leaning structure. The visual below maps a documented 13-week cycle built from 4weeks of vegetative growth and the strain's published flowering window.
Published grow reports for Romulan concentrate the most observational notes on the late-flower ripening window. This timeline is descriptive — it reflects what reports document, not a how-to. Actual week-to-week behaviour varies with phenotype, light intensity, pot size, and environment.
Phase details
- Veg (weeks 1-4)
- The documented vegetative period for Romulan. Plants establish root structure, leaf canopy, and node count before flower triggering, with a moderate difficulty rating shaping how forgiving the early canopy work tends to be.
- Stretch (weeks 5-7)
- Romulan is documented as having low stretch. Reports describe the plant roughly doubling in height during this phase as the indica-leaning structure establishes its final flowering frame.
- Bud sites (weeks 8-9)
- Pre-flowers form at the nodes and calyxes begin to develop. Grow reports for Romulannote this as the window where the canopy's eventual bud distribution becomes visible.
- Bud development (weeks 10-11)
- Flowers thicken and calyxes fatten through this phase. Documented Romulan runs show the bulk of visible flower mass accumulating here, with resin production accelerating toward the end.
- Ripening (week 12)
- Trichomes transition from clear toward cloudy and amber. Reports for Romulan describe the Pinene-led terpene profile maturing through this window, with aroma sharpening week over week.
- Final (week 13)
- Calyx swelling is documented as complete and the harvest window opens. Published Romulan runs end here, within the 8-9 week flowering range reported by the breeder.

Common questions about Romulan
Where did Romulan actually come from?
The strain originated with Mighty Mite Seeds in British Columbia during the late 1970s from an unnamed North American indica selection. Federation Seeds carried the commercial release through the 1990s before DNA Genetics took up the working line in the 2000s.
Why is Romulan good for cool climates?
The Canadian indica background gives Romulan strong mold and pest resistance and a fast eight-to-nine-week finish, both of which suit cool, damp temperate climates where slower-finishing strains run into late-season rot. The squat structure also handles wind and rain better than tall sativa-leaning plants.
