Rucu Cucu OG Auto (Seedstockers)

Rucu Cucu OG Auto Seeds by Seedstockers

Rucu Cucu OG Auto is an autoflowering cannabis seed strain that crosses Tangie with OG Kush Auto to deliver XXL harvests of sweet, citrus-drenched buds in just 10–11 weeks from seed. Born from a collaboration between Seedstockers and Argentinian rapper Homer El Mero Mero, this sativa-dominant auto brings 26% THC and genuinely impressive yields to growers who don't want to fuss with photoperiod lighting schedules.

Why Rucu Cucu OG Auto Seeds Deserve Your Grow Space

Most autoflowers force you to choose: either you get speed and convenience, or you get the kind of potency and yield that photoperiod strains deliver. Rucu Cucu OG Auto doesn't ask you to compromise. At 26% THC, this strain sits comfortably in territory that many photoperiod genetics struggle to reach. And the yields? Seedstockers calls them XXL, and from what we've seen, that's not marketing fluff — this plant produces oversized, resin-caked buds that genuinely fill jars.

The Tangie x OG Kush Auto cross gives you the best of both parents. Tangie brings that unmistakable citrus sweetness — think ripe tangerines with a candy edge — while OG Kush Auto contributes earthy depth, structural vigour, and the autoflowering gene. The result is a plant that smells like a fruit bowl, grows like it's on a mission, and finishes before most photoperiod strains have even started flowering.

Here's the honest limitation: she stretches. Quite a lot. If you're working in a small tent — say 60x60cm — you'll want to start low-stress training early, or you'll be fighting for headroom by week six. In a taller space or outdoors, that height is an advantage: more nodes, more bud sites, more weight at harvest. We'd pick a pot of at least 15 litres if you want her to reach full potential; 7 litres works but will cap her size.

Tangie x OG Kush Auto: Flavour and Aroma Profile

Rucu Cucu OG Auto produces buds that smell intensely sweet and fruity from the moment they start forming. The dominant notes are ripe citrus — tangerine specifically — layered over a creamy, almost dessert-like base. Crack open a cured bud and you'll catch earthy undertones that ground the sweetness and stop it from being one-dimensional. According to a review published in PMC, terpene profiles in Cannabis sativa vary widely depending on genetics and growing conditions, with citrus-forward strains typically rich in limonene and myrcene (PMC7763918). That terpene combination is exactly what gives Rucu Cucu OG Auto her distinctive sweet-and-earthy character.

The taste follows the nose closely. On the inhale, it's bright citrus fruit with a sugary edge. On the exhale, that creaminess and earthiness come through. It's a genuinely enjoyable flavour profile — the kind that makes you want to take your time rather than rush through a session. If you've grown Tangie crosses before, you'll recognise the family resemblance, but the OG Kush side adds a savoury complexity that straight Tangie genetics lack.

How to Grow Rucu Cucu OG Auto Seeds

1. Germinate your seeds using the paper towel method or by placing them directly into moist soil or coco coir. Keep the environment warm — around 22–25°C — and expect taproots within 24–72 hours.
2. Plant the germinated seed about 1–2cm deep in your chosen medium. Use a pot of at least 7 litres, though 15 litres or more will let Rucu Cucu OG Auto reach her full XXL potential. With autoflowers, plant in the final pot from the start — transplanting costs you growth time you can't get back.
3. Provide 18–20 hours of light per day throughout the entire lifecycle. Autoflowers don't need a light schedule change to trigger flowering, so keep the lights on and let her do her thing.
4. Begin low-stress training (LST) once the plant has 4–5 nodes. Gently bend the main stem away from the centre and secure it with soft ties. This opens up the canopy, controls height, and encourages more even bud development across all branches. Given this strain's love of vertical growth, early training is worth the effort.
5. Feed lightly during the vegetative phase and increase nutrients gradually as flowering begins. Autoflowers are generally more sensitive to overfeeding than photoperiod plants, so err on the side of less rather than more.
6. Watch for the stretch during early flowering — Rucu Cucu OG Auto can nearly double in height during this phase. Adjust your light height accordingly and continue LST if needed.
7. Harvest at 10–11 weeks from seed. Check trichomes with a jeweller's loupe: mostly milky with a few amber is the sweet spot for the uplifting, relaxing effect profile this strain is known for.
8. Dry in a dark room at around 18–20°C and 55–60% humidity for 7–10 days, then cure in glass jars for at least 2 weeks. The citrus and cream flavours really develop during a proper cure — don't rush this step.

Rucu Cucu OG Auto vs the Original Photoperiod

The original Rucu Cucu OG — the photoperiod feminised version — is a beast in its own right. Massive yields, the same sweet citrus flavour, and THC levels that some competitor listings put as high as 30%. So why go auto?

The auto version trades a small amount of peak THC potential for dramatically simpler cultivation. No light schedule changes, no worrying about light leaks during dark periods, and a fixed timeline from seed to harvest. For most growers — especially those running a perpetual cycle or growing on a balcony — the auto is the smarter pick. If you're chasing absolute maximum potency and have the setup for photoperiod growing, the feminised version edges ahead. But 26% THC is nothing to scoff at.
