How to Germinate Steve’s Alien OG Seeds
A healthy harvest starts at germination. The paper towel method is hard to beat: fold the Steve’s Alien OG seeds inside two damp sheets, slide them between two plates, and keep them somewhere dark at 70 to 79°F. A taproot usually appears in one to five days.
Once the root is a few millimetres long, move each seed into its starter pot with the root pointing down and cover it with about 2 cm of soil. Keep the medium lightly moist, not soaked, and hold humidity around 65 to 70% while the first true leaves open. Because these are feminized seeds, you can skip sorting out males later and give every sprout your full attention.
Starter tips
- Use plain, lightly pH-balanced water (pH 5.5 to 6.5) for the first week.
- Give seedlings gentle light, not a full-power lamp pressed overhead.
- Hold off on nutrients until the second set of serrated leaves appears.
Growing Steve’s Alien OG in the Vegetative Stage
Steve’s Alien OG likes a tropical to warm climate with plenty of light. Its Tahoe OG side prefers drier air, so aim for day temperatures of 68 to 82°F and keep veg humidity in the 50 to 60% band. An airy substrate with perlite, peat or coco coir holds moisture without drowning the roots.
Its warmth-loving, compact nature suits a range of US regions, though its dense OG buds want air moving around them:
- Southern California: the warm, dry Mediterranean season is close to ideal and keeps the dense, resinous buds clean to an October harvest.
- Gulf Coast and South Florida: the tropical warmth it enjoys comes with humidity, so lean on airflow and defoliation to keep bud rot off the dense colas.
- Indoors anywhere: at around 3.94 ft it is compact and tidy, ideal for tents where you can control the humidity its OG side prefers.
At around 3.94 ft this is a short, bushy OG plant. Top it once it has five or six nodes, and use low-stress training to open the tight internodes and spread the branches so light reaches every bud site, which is how you coax the most from a compact, medium-yielding OG.
Flowering and Buds of Steve’s Alien OG
Once you switch to a 12/12 light cycle, Steve’s Alien OG finishes in 8 to 10 weeks. It does not stretch much, staying compact, and it rewards you with dense, chunky, resin-caked buds that give off a citrus, herbal and spicy OG aroma.
Drop humidity to 40 to 45% during flower and keep airflow moving through the canopy, which matters because the dense OG buds hold moisture and the plant dislikes damp. Support the heavier branches as the colas fatten, and outdoors plan for an October harvest.
At 22 to 28% THC it frosts over with a heavy resin layer, so judge ripeness by the trichomes rather than the calendar.
Common Problems and Pro Tips
Steve’s Alien OG is beginner-friendly but, like any OG, it has a few quirks worth knowing.
- Humidity and mould: its Tahoe OG side dislikes damp air and the dense buds trap moisture, so keep humidity down, run good airflow and defoliate to open the canopy, especially in a humid, tropical spot.
- Calcium and magnesium: OG genetics are prone to Cal-Mag deficiency and rusty leaf spots, so a light Cal-Mag supplement keeps them clean and healthy.
- Nutrient sensitivity: OGs can burn on a heavy feed, so start low and build up slowly, and check leaf undersides weekly for spider mites.
Expert tip: because it stays short with tight internodes, a little low-stress training and defoliation to open the canopy pay off more than with a tall plant, letting light into the lower buds to lift its medium yield. Those dense, resinous OG flowers also make excellent hash, so save every scrap of frosty trim, and a touch of cool, dry air late in flower sharpens the citrus-and-spice OG nose.
Aroma, Flavor and Effects
The nose is a classic OG mix with a twist: bright citrus up front over a deep, herbal, spicy base from its Alien Kush and Tahoe OG parents. It reads pungent and savory rather than sweet, and it sharpens as the buds cure in the jar.
The flavor follows, citrus and herbal with a peppery, spicy OG finish. On the effect side it is happy, relaxed and talkative, an easygoing, sociable lift with a comfortable OG body ease from its 55% indica makeup, which makes it a mellow, potent classic.
Terpene profile
The published profile leads with Myrcene, the most common cannabis terpene, which brings a ripe, earthy depth and underpins the relaxing OG body feel. It is the base that the bright citrus top note and the herbal, peppery spice sit on, giving the aroma its savory, grounded character. A slow cure is what pulls those citrus and spicy-herbal notes fully forward over that myrcene base.
Nutrient Schedule
Treat the figures below as a starting map, not a rulebook. Steve’s Alien OG takes a moderate feed but, like most OGs, can burn if pushed, so lean toward the low end and read the plant first: tip burn means back off, while pale, slow growth means it wants a little more. All values use EC.
| Stage | EC |
|---|---|
| Seedling | 0.4–0.6 |
| Growth | 0.8–1.2 |
| Early flower | 1.2–1.4 |
| Full flower | 1.4–1.6 |
| Flush | 0.0–0.4 |
Keep the pH around 6.0 to 6.5 in soil and 5.5 to 6.0 in hydro so the roots can actually take up what you feed.
What to Do With Your Trim: Extracts and Hash
Steve’s Alien OG lays down a heavy, pungent OG resin layer, so the trim is well worth keeping. The frosty sugar leaves you take off while manicuring carry plenty of trichomes and suit Ice Water Hash, where cold water and agitation separate the resin heads into a clean, solventless concentrate. Pressing that hash into rosin keeps the citrus-and-spice OG flavor intact, and OG genetics are a classic choice for top-shelf hash, or you can run a solvent extraction if that is your setup. The bare stems will not extract, but chopped and composted they feed organic matter back into the soil for your next grow.
Harvesting, Drying and Curing Steve’s Alien OG
Timing the harvest comes down to the trichomes. Grab a loupe and watch the heads turn from clear to milky white; a scattering of amber signals peak ripeness. Outdoor plants usually reach that point in October, while indoor runs land at the end of the 8 to 10 week flowering window.
After the cut, hang the branches in a dark room at 59 to 68°F with humidity near 50% and gentle air movement. Slow beats fast: drying over 10 to 14 days protects the citrus, herbal and spicy OG aromas that define this strain. When the small stems snap instead of bending, move the buds into jars.
Cure in sealed glass, opening the jars daily for the first week to let moisture escape, then easing off as the aroma deepens. Two to four weeks of patience here is where the classic OG pungency really comes forward, and it is the step most first-time growers rush.
