Quick Hits
What kind of high is Romulan?
An indica-dominant hybrid reported as relaxed, sleepy and euphoric. Picked for watching tv/movies and sleep & bedtime at night. The profile features earthy pine flavor and aroma and myrcene as the lead terpene.
Terpenes are natural compounds that give cannabis its smell. Compare citrus, pine, and earthy notes to find what you like. They are clues, not a promise of how it feels.
Terpene percentages belong to the jar, not the strain. They move with harvest timing, drying, cure and shelf age — the lighter ones literally evaporate. What holds steady is which terpenes lead, so that is what we rank.

Professor High on Romulan
The first thing I notice is the pine — sharp, forest-fresh, cutting through an earthy sweetness before I even finish the exhale. Within minutes, a euphoric brightness washes over my thoughts, almost surprising for something this indica-heavy. I feel happy, a little uplifted, even briefly sharp and creative — like my brain got a clean signal boost.
Then the myrcene kicks in. My shoulders drop, my limbs get heavy in that satisfying, sink-into-the-couch way, and the euphoria mellows into a warm, contented haze. My eyes get a little dry, my mouth too — classic indica territory. As the high stretches into its second act, hunger creeps in and my eyelids get heavy. This is a strain that starts like a good conversation and ends like a good night's sleep. Educational note: that pine-caryophyllene combo is doing real work on physical tension, not just vibes.
