Communion
Also known as Communion S1, COM
Communion is a sativa-leaning hybrid (30% Indica/70% Sativa) crossing Grapestomper OG, Durban Poison, and Romulan genetics. Expect grape-and-diesel flavors, a caryophyllene-forward terpene profile, and effects that swing between energetic focus and tingly relaxation. THC ranges widely from 17. 2–27. 4%, making it a flexible, rare-find hybrid for creative sessions, socializing, or a mellow evening wind-down. Read more Show less
Quick Hits
What kind of high is Communion?
A sativa-dominant hybrid reported as euphoric, relaxed and creative. Picked for focus & concentration and evening wind down at any time of day. The profile features sweet grape flavor, earthy grape aroma and caryophyllene as the lead terpene.
Terpenes help give cannabis its aroma. Compare citrus, pine and earthy notes to find what appeals to you. The profile offers clues, not a guaranteed high.
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.

There’s more to a strain than THC%.
THC percentage is a property of the product in your hand, not of the strain. It shifts with the batch, the grower, the harvest, and how the flower was cured and stored — the same strain can test several points apart from two different jars.
Treat the ranges below as market context for what to expect on a shelf — then read the actual label on the product you are buying, and use the terpene profile to judge how it will feel.

Professor High interprets the pattern
The moment this hits, I feel Durban Poison's sativa spine snap me into bright, clear-headed focus — thoughts organize themselves, creative ideas start connecting. Then, a few minutes later, the Romulan and Grapestomper OG side rolls in underneath: a tingly, warm body settle that doesn't drag me down, just anchors me. The caryophyllene is doing real work here — that peppery bite in the exhale correlates with a subtle physical ease across my shoulders. Flavor-wise, I'm getting sweet grape candy up front, diesel and pine cutting through the middle, and an earthy herbal finish that lingers pleasantly. What's fascinating is how dual-natured this high feels — genuinely uplifted and social one moment, comfortably grounded the next. It's not a strain that pins you to the couch, but it's also not pure cerebral buzz. It's a negotiated balance between the three parent genetics, and you can feel each one taking a turn.

The helpful detail
Communion: A Three-Way Genetic Experiment from Romulan Genetics
Communion is a hybrid built from an unusual three-parent cross, blending Grapestomper OG, Durban Poison, and Romulan genetics. The result is a strain that source data places anywhere from 50/50 balanced to 70% sativa-dominant, with the consolidated ratio landing at 30% Indica / 70% Sativa. This spread across sources reflects real phenotype variation — different Communion cuts (Communion S1, COM) express the sativa energy of Durban Poison or the indica density of Romulan to varying degrees depending on the grower and seed bank.
🧬 Genetic Heritage & Lineage
- Grapestomper OG contributes the grape-candy sweetness and OG resin structure
- Durban Poison brings sativa vigor, clear-headed alertness, and the piney/spicy edge
- Romulan rounds things out with a dense, relaxing body-load
- Bred and distributed by Romulan Genetics, with additional releases through Mandala Seeds and North Atlantic Seed Co
- Classified as a Type II chemovar, meaning it carries a meaningful THC-to-CBD ratio rather than being THC-dominant alone
👃 Terpene Profile & Aromatics
Communion's dominant terpene is Caryophyllene, a peppery, spicy compound known for CB2-receptor interaction and body-soothing potential. Supporting terpenes reported across grow reports and lab-adjacent listings include:
- Terpinolene — herbal, piney sharpness that fuels the uplifted, energetic feel
- Myrcene — earthy, musky depth that grounds the high
- Limonene — bright citrus lift supporting mood elevation
- Linalool — soft floral calm that smooths out sharper edges
- Humulene — woody, subtly bitter, tied to anti-inflammatory potential
No lab-verified percentages exist yet (data quality is anecdotal), so treat this profile as directional rather than exact. The aroma itself is a layered bouquet: grape and sweet fruit up front, sliding into pine, diesel, and earthy herbal notes, with spicy, woody, and tropical undertones rounding out the nose.
👅 Flavor Experience
The inhale leans into sweet grape and tropical fruit, transitioning mid-palate to pine and diesel fuel notes. The exhale settles into earthy, herbal, and lightly spicy territory, with berry and citrus flickering through on some phenotypes — a genuinely complex flavor journey for a hybrid this accessible.
🎯 Effects & Experience
Reported effects span euphoric, relaxed, creative, happy, energetic, focused, uplifted, and tingly. The Durban Poison influence tends to surface first as clear-headed, energizing euphoria and sharpened focus, while the Romulan/OG side settles in as a relaxed, tingly body feel without heavy sedation for most users. THC has been tested anywhere from 17.2% to 27.4%, with CBD staying low at 0.05–0.7%, so potency and intensity can vary meaningfully by batch and source.
🎮 Use Cases & Activities
The combination of mental clarity and physical ease makes Communion suited to creative projects, focus & concentration work, socializing, and, in lower doses, evening wind-down. It's a hybrid that can flex across the day rather than locking you into one mode.
💚 Medical & Therapeutic Potential
Users commonly report Communion may help with anxiety, stress, depressive symptoms, and focus challenges on the mental side, and with chronic pain, sleep difficulty, and nerve-related discomfort on the physical side. These are user-reported patterns, not clinical claims.
⚠️ Consumer Considerations
Dry mouth is the most consistently reported side effect. Given the wide THC range across tested batches, new or dose-sensitive users should start low and go slow, especially with cuts testing near the 27% ceiling. Availability is rare, sourced primarily through Romulan Genetics, Mandala Seeds, and North Atlantic Seed Co, giving Communion a boutique, cult-strain reputation rather than mass-market presence.
