What is the Alien OG strain?
Alien OG is a balanced hybrid released by The Cali Connection from a Tahoe OG mother and an Alien Kush male selected for its Alien Technology traits. Leafly reports it at about 19% THC, while AllBud and seed-bank sheets go as high as 28%, with low CBD. Feminized versions flower in about 8 to 10 weeks, finish outdoors in early October, and are reported to give a relaxed, tingly body feel with a euphoric head.
Royal Queen Seeds and AllBud list 50/50; Blimburn Seeds and Alien Genetics' related Tahoe Alien lean indica.
Weedmaps and Royal Queen Seeds both describe Alien OG buds coated in trichomes, with orange pistils over bright green flowers.

Where does the Alien OG strain come from?
Alien OG was released by The Cali Connection in California as a cross of a Tahoe OG mother and an Alien Kush male chosen for its Alien Technology traits. Tahoe OG is the breeder's own OG Kush line, which The Cali Connection describes as an original OG Kush clone from Lassen County in Northern California. Alien Kush comes from Alien Genetics and combines Las Vegas Purple Kush with Alien Technology, an Afghan indica that Obsoul33t is said to have selected from seeds brought back from Afghanistan.
SeedFinder lists Tahoe Alien as another name for the strain, and Alien Genetics sells its own Tahoe OG × Alien Kush cross under that name. The release year and selection details have not been published. The Cali Connection's original line was never offered feminized, so feminized Alien OG today comes from seed companies such as Royal Queen Seeds and Blimburn Seeds, whose figures this page uses.
Is Alien OG the same as Alien Kush?
No: Alien Kush is one of Alien OG's parents, not another name for it. Alien Kush is Las Vegas Purple Kush × Alien Technology, a mostly indica plant, while Alien OG adds a Tahoe OG mother and with it a stronger OG Kush character and a more balanced hybrid effect. Some shops shorten Alien OG to Alien OG Kush, which adds to the mix-up.
There is more than one Alien Kush. Weedmaps notes that The Cali Connection also sells an Alien Kush made with Alien Dawg, so check which version a seed maker means.
What does Alien OG taste like, and how does it feel?
Aroma and flavor
Alien OG tastes of sour lemon and pine over an earthy, fuel-like base, with a light sweetness and a hashy finish that Weedmaps reviewers often mention.
- Lemon
- Pine
- Earthy
- Diesel
- Sweet
- Hash
Terpenes
- Myrcene
- Earthy, musky depth
- Caryophyllene
- Peppery spice
- Limonene
- The sour lemon top note
Leafly lists these three as Alien OG's top terpenes; the balance varies by phenotype and grow.
Reported effects
Users most often describe Alien OG as relaxing and tingly with a strong euphoric lift, and Weedmaps reviewers note physical calm alongside a lively, sometimes racy mind. AllBud reviewers call it a creeper that builds slowly and lasts.
- Relaxed
- Tingly
- Euphoric
- Happy
- Uplifted
Leafly users list dry mouth, dry eyes and headache as Alien OG's most common downsides, and several AllBud reviewers warn that its strength is not for beginners.
These Alien OG effects summarize Leafly, AllBud and Weedmaps user reports plus breeder descriptions. Your own response may differ, and nothing here is medical advice.
How do you grow Alien OG seeds?
Alien OG feminized seeds are a moderate grow: veg for 4 to 6 weeks, top and train early, switch to 12/12 and expect a strong stretch, then flower for about 8 to 10 weeks with good airflow and odor control.
- Germinate3–7 days
Alien OG seedlings like a mild, steady environment; keep the medium damp but never soggy until the roots establish.
- Vegetate4–6 weeks
Top Alien OG once or twice and spread the branches with LST, since growers report a big stretch after the light change.
- Flower8–10 weeks
Most of the height gain comes in the first three weeks of 12/12, followed by dense, frosty buds with orange pistils.
- HarvestDay 56–70 · early Oct outdoors
Judge by trichomes rather than the calendar: one SeedFinder grower cut at 56 days, while most sheets give 60–65.
Grow tips for Alien OG
- Set the canopy before the flip. A SeedFinder grower saw Alien OG stretch hard for about three weeks after the light change, so top and tie it down during veg.
- Plan for a loud smell. Alien OG's lemon, pine and fuel aroma gets strong late in flower, so run a carbon filter in any indoor space.
- Support the top colas. Resin-heavy Alien OG tops can lean in the final weeks; a trellis net or a few stakes keeps them upright and spaced.
- Keep humidity in check. Weedmaps notes that Alien OG's dense flowers make airflow and moisture control important as the buds mature, so keep late-bloom humidity low.
- Outdoors, finish by early October. Royal Queen Seeds gives an early-October harvest and calls its Alien OG resistant to mold and pests, but a dry autumn still matters.
- Fill the space with females only. Every feminized Alien OG seed grows a female, so you can plant to your space without sexing seedlings or removing males.
