OMG Feminised Cannabis Seeds by Ripper Seeds
OMG is a feminised cannabis seed from Ripper Seeds that crosses GMO (Garlic Cookies) with Kush Mints to produce a resin-drenched, fast-flowering hybrid with serious bag appeal. If you want dark purple flowers caked in trichomes and a flowering time that won't test your patience, this is the one to watch. Ripper Seeds built this strain from top-shelf US genetics, and the results speak for themselves — vigorous growth, heavy yields, and a terpene profile that fills the room.
Why OMG Cannabis Seeds Deserve a Spot in Your Grow Room
We've seen a lot of US-genetics crosses come through the catalogue over the years, and the GMO (Garlic Cookies) lineage consistently produces some of the most resinous, pungent plants out there. Ripper Seeds took that Chem Cookies variant and paired it with Kush Mints — a strain already famous for its speed and productivity. The result is OMG: a 60/40 indica-dominant hybrid that grows with real vigour, finishes in 65 to 70 days of flowering, and stacks on resin like it's getting paid by the trichome.
The visual payoff alone makes this strain worth growing. Expect dark purple flowers — proper deep purple, not just a hint — blanketed in thick, crystalline resin. The contrast between that dark bud structure and the frosty white trichome coverage is genuinely striking. If you've ever wanted a plant that looks as good as it performs, OMG delivers.
Outdoors, she'll be ready by mid-October, which suits most European climates. Indoors, that 65-70 day window keeps your cycle tight. Yields sit well above average thanks to the Kush Mints parentage — that side of the family brings the speed and the bulk.
OMG Terpene Profile and Flavour Notes
This is where OMG gets interesting. The terpene profile spans sweet, garlicky, diesel, and mint — all in one plant. The GMO parent contributes that unmistakable garlic-and-cookies funk, while Kush Mints layers in cool, refreshing mint notes and a crisp finish. There's a diesel backbone running through it too, courtesy of the Chem Cookies heritage. It's not a simple flavour — it's layered, and each inhale reveals something different. If you've grown GSC-family strains before, imagine that profile turned up and given a savoury, minty twist.
The aroma during flowering is intense. Plan your carbon filtration accordingly — this is not a subtle plant. By week 6, your tent will smell like a garlic bread factory crossed with a mint garden, and honestly, that's part of the charm.

Growing OMG Seeds — What to Expect
OMG is a grower-friendly strain, but she rewards attention. The Kush Mints genetics give her a natural vigour that pushes through veg with purpose — she doesn't hang about. In a standard indoor setup, you can expect a medium-tall plant with solid lateral branching. She responds well to topping and LST, and the node spacing stays tight enough to build a dense canopy without much fuss.
The one thing to watch: humidity in late flower. Those dense, resin-heavy buds combined with the thick foliage can create pockets of trapped moisture. Keep your airflow strong and your RH below 50% once you're past week 5 of flowering. We've seen too many growers lose beautiful colas to botrytis in the final stretch because they got complacent with ventilation. A clip fan aimed at the canopy and a decent extraction setup will save you from heartbreak.
Outdoors, she wants a warm, dry autumn to finish properly. Mediterranean climates are ideal. If you're growing in northern Europe, keep an eye on the weather forecast from early October and be ready to harvest a few days early if persistent rain rolls in.
How to Germinate and Grow OMG Cannabis Seeds
- Soak your OMG seeds in a glass of room-temperature water (20-22°C) for 12 to 24 hours, until they sink to the bottom.
- Transfer the seeds to damp paper towels inside a sealed container. Keep them in a dark, warm spot (22-25°C). Check daily — taproots usually appear within 24 to 72 hours.
- Once the taproot reaches 1-2cm, plant the seed 1cm deep in your chosen medium (soil, coco, or rockwool), taproot facing down.
- Maintain a humidity of 65-70% during seedling stage. Use a humidity dome if needed. Keep lights at 18/6.
- Veg for 3-5 weeks depending on your space. Top once above the 4th or 5th node if you want to encourage bushier growth and more bud sites.
- Flip to 12/12 when the plant reaches roughly half your target final height — she'll stretch during the first 2 weeks of flower.
- Monitor humidity closely from week 5 of flowering onward. Drop RH to 45-50% and increase airflow around the canopy.
- Harvest at 65-70 days of flowering. Check trichomes with a jeweller's loupe — aim for mostly cloudy with 10-20% amber for the full effect profile.
OMG vs Other Kush Mints Crosses — How Does She Compare?
| Trait | OMG (Ripper Seeds) | Typical GMO / Garlic Cookies |
|---|---|---|
| Genetics | GMO x Kush Mints | Chem Cookies (GSC x Chemdawg) |
| Flowering Time | 65-70 days | 70-80 days |
| Indica/Sativa | 60/40 | 90/10 |
| Yield | Above average | Average to above average |
| Flavour Profile | Sweet, garlic, diesel, mint | Garlic, earthy, diesel |
| Resin Production | Outstanding | Heavy |
| Bud Colour | Dark purple with heavy frost | Green to light purple |
The big difference is speed and balance. Pure GMO clones tend to lean heavily indica — 90/10 in most cuts — and take 70-80 days to finish. OMG shaves a week or more off that flowering time thanks to the Kush Mints influence, and the 60/40 split means you get a more balanced effect rather than pure couch-lock. The mint and sweet notes from Kush Mints also add a freshness to the flavour that straight GMO doesn't have. If you've grown GMO before and wished it was faster and a bit more uplifting, OMG is the answer.
Honest Limitations — What to Know Before You Buy
No strain is flawless, and OMG has a couple of things worth knowing. First, the aroma. She is loud. During weeks 5-9 of flowering, your carbon filter will be working overtime. If you're growing in a shared building or anywhere discretion matters, factor in a quality carbon filter and sealed ducting — this is not a quiet plant.
Second, the dense bud structure that makes her so productive also makes her more susceptible to mould in high-humidity environments. If you're growing in a basement or a space where you struggle to keep RH below 55%, you'll need to stay on top of defoliation and airflow. She's not fragile — she just needs you to do your part.
Third, this pack comes with 3 seeds. That's standard for Ripper Seeds feminised lines, but if you're hoping to pheno-hunt through a larger batch, you'll need to pick up more than one pack.
Complete your setup: pair OMG seeds with a carbon filter and extraction fan kit to manage that intense garlic-mint aroma during flowering. A jeweller's loupe is also worth grabbing — checking trichome colour is the only reliable way to nail your harvest window on a strain this resinous.
Frequently Asked Questions
How long does OMG take to flower?
OMG finishes in 65-70 days of flowering indoors. Outdoors, expect to harvest around mid-October. The Kush Mints parentage keeps her on the faster side compared to most GMO-derived strains, which typically run 70-80 days.
Is OMG by Ripper Seeds indica or sativa?
OMG is a 60% indica, 40% sativa hybrid. Despite the indica dominance, Ripper Seeds describes her effect as a strong head-focused experience with creative, uplifting qualities — not the heavy sedation you might expect from a 60/40 split.
What does OMG taste and smell like?
The flavour profile combines sweet notes, garlic, Cookie diesel, and refreshing mint from the Kush Mints parent. The aroma during flowering is very strong — plan your odour control accordingly. It's a complex, layered terpene profile that stands out from simpler Cookie crosses.
How much does OMG yield?
Ripper Seeds rates OMG as above-average yielding. The Kush Mints genetics contribute strong vigour and productivity. With proper training (topping, LST) and good environmental control, you can push yields further. She responds well to a ScrOG setup.
What are the parent strains of OMG?
OMG is a cross of GMO (also called Garlic Cookies — a potent US variant of Chem Cookies derived from GSC x Chemdawg) and Kush Mints. The combination brings GMO's resin production and complex flavour together with Kush Mints' speed and vigour.
Is OMG suitable for beginner growers?
She's manageable for growers with at least one grow under their belt. The main challenge is humidity management during late flower — those dense, resinous buds need good airflow. If you can keep your RH below 50% in the final weeks and run a decent extraction setup, you'll be fine.
Can I grow OMG outdoors in northern Europe?
Yes, but keep an eye on autumn weather. She finishes mid-October, which works in most years, but persistent rain in the final weeks can cause mould issues with her dense buds. A warm, dry autumn is ideal. Have a backup plan to harvest early if the forecast turns wet.
