Herz OG Feminised Cannabis Seeds by Exotic Seed
Herz OG is a feminised cannabis seed strain that crosses two heavyweight OG Kush phenotypes — Larry OG and Kosher Kush — into a 60/40 indica-dominant hybrid built for potency and flavour. This is the first-ever collaboration between a European seedbank and a German rap artist, with Exotic Seed and rapper Herzog developing the genetics together from the ground up. The result already has competition wins under its belt, and the seed hasn't been on the market long.
Why Herz OG Deserves a Spot in Your Grow Room
We've seen plenty of "celebrity strains" that are little more than a sticker on an existing genetic. Herz OG isn't that. Exotic Seed — a Spanish-Dutch operation with genuine breeding chops — actually worked with Herzog to cross two specific OG Kush cuts that both have serious reputations on their own. Larry OG (also called Lemon Larry) brings that sharp, piney OG structure. Kosher Kush adds density, resin production, and a deep, almost savoury earthiness. Crossing the two keeps you firmly in OG territory but widens the terpene profile in a way that neither parent manages alone.
The indica lean shows in the plant structure: compact, bushy, with tight internodal spacing that stacks into dense colas by week seven or eight. If you're growing in a tent with limited vertical space, that's good news. She doesn't stretch much during the flip, so you can veg a little longer without running into light-burn territory. Outdoors in a southern European climate, expect harvest around mid-October — she finishes before the autumn rains get serious.
The honest limitation? She's not the highest yielder in the Exotic Seed catalogue. At 400–450 g/m² indoors, she sits in the medium range. If you're chasing weight above everything else, something like a Gorilla Glue cross will outproduce her. But if you're after a specific flavour profile and a proper OG-style effect that even seasoned smokers notice, Herz OG punches well above that yield number in terms of quality per gram.
Herz OG Aroma and Flavour Profile
This is where Herz OG earns its keep. Crack a cured bud open and the first thing that hits you is fresh-cut pine — not the cleaning-product kind, but actual resinous wood. Behind that sits a warm honey sweetness that rounds out the inhale and lingers on the exhale. There's a subtle earthiness underneath, almost like damp forest floor after rain, which is classic Kosher Kush heritage showing through. The Larry OG side contributes a faint citrus edge that you catch more on the nose than on the tongue. Growers who've run both parents will recognise bits of each, but the combination creates something distinct — deeper and more layered than either parent alone.
If you're a flavour chaser who appreciates a proper OG terpene profile without the generic "kush" sameness, this one's worth your attention. The resin production is heavy enough that even a small harvest fills a room with scent during the final two weeks of flower. A carbon filter isn't optional here.

Herz OG Genetics: Larry OG Meets Kosher Kush
Understanding the parents tells you a lot about what to expect. Larry OG is an OG Kush x SFV OG cross that's been a staple in California dispensaries for years — known for a strong lemon-pine nose and a balanced but potent effect. Kosher Kush, meanwhile, has won multiple Cannabis Cup awards and is one of the few strains to be blessed by a rabbi (yes, really). It's a pure indica-leaning OG cut famous for extreme resin production and a sedating, full-body effect.
Crossing the two keeps the OG backbone intact while combining Larry's sharper terpene edge with Kosher's heavy resin and physical relaxation. The 60/40 indica split means the plant grows like an indica — stocky, manageable, not too stretchy — but the 40% sativa genetics add enough mental engagement to keep the effect from being a one-dimensional couch-lock. It's an OG-on-OG cross, which means experienced OG growers will feel right at home with the feeding schedule and environmental preferences.
How to Grow Herz OG Seeds
- Germinate your Herz OG seeds using the paper towel method or directly in a starter plug. Feminised seeds mean every plant should flower — no need to sex them.
- Transplant seedlings into their final containers once the first true leaves appear. A 15–20 litre pot works well for indoor grows; outdoors, go larger if your climate allows a full veg cycle.
- Veg for 4–5 weeks under 18/6 lighting. Herz OG stays compact, so you can afford a slightly longer veg than you'd give a stretchy sativa. LST (low-stress training) or topping at the third or fourth node opens up the canopy and boosts light penetration to lower bud sites.
- Flip to 12/12 when the plant fills roughly 60–70% of your available canopy space. Expect minimal stretch — maybe 30–40% height gain during the first two weeks of flower.
- Feed a standard indica flowering schedule. She's not a particularly heavy feeder, but she responds well to a PK boost from week 5 onwards. Watch for calcium deficiency in coco — OG genetics can be finicky about cal-mag.
- Monitor humidity closely from week 6 onwards. Those dense, resinous colas are mould magnets if relative humidity climbs above 50%. Good airflow and a dehumidifier are your friends here.
- Harvest at 9 weeks of flower when trichomes show mostly milky with 10–20% amber. Dry slowly in a dark room at 18–20°C and 55–60% RH for 10–14 days, then cure in jars for at least two weeks. The terpene profile develops significantly during a proper cure — don't rush it.
Herz OG vs Other OG Kush Crosses
| Trait | Herz OG | Typical OG Kush | Kosher Kush (pure) |
|---|---|---|---|
| Genetics | Larry OG x Kosher Kush | Chemdawg x Lemon Thai x Hindu Kush | OG Kush phenotype (pure indica lean) |
| Flowering Time | 9 weeks | 8–9 weeks | 9–10 weeks |
| Indoor Yield | 400–450 g/m² | 350–450 g/m² | 350–400 g/m² |
| Dominant Terpenes | Pine, honey, fresh wood | Pine, lemon, fuel | Earth, pine, spice |
| Indica/Sativa | 60/40 | 55/45 | 80/20 |
| Best For | Flavour chasers, OG enthusiasts | All-round classic | Maximum sedation, resin hunters |
If you want the classic OG experience with more terpene complexity and a slightly more engaged headspace than pure Kosher Kush delivers, Herz OG sits in a sweet spot between the two. It's the best OG cross for growers who want award-winning genetics without the 10-week flowering commitment of heavier indica cuts.
Running Herz OG in a tent? Pair these seeds with a complete grow kit that includes lighting, ventilation, and a carbon filter — you'll need one for the smell by week 7. If you're after a different OG expression to run alongside, Larry OG or Kosher Kush seeds from other banks make a great comparison grow.
The Backstory: Herzog x Exotic Seed
In the US, rappers having their own cannabis strains is practically standard — Wiz Khalifa has Khalifa Kush, Berner built Cookies into a global brand, and Snoop's involvement in cannabis is its own industry. In Europe, that crossover between hip-hop culture and cannabis breeding barely existed until Exotic Seed approached German rapper Herzog. The collaboration produced Herz OG (a play on Herzog's name and the OG lineage), making it the first strain partnership between a seedbank and a German-language artist. Whether you follow German rap or not, the genetics speak for themselves — this isn't a vanity project with a famous name slapped on a bag seed. The breeding work is real, and the awards it's already picked up back that up.
Frequently Asked Questions
What is Herz OG?
Herz OG is a feminised cannabis seed strain from Exotic Seed, crossing Larry OG with Kosher Kush. It's a 60% indica / 40% sativa hybrid developed in collaboration with German rapper Herzog — the first strain partnership between a seedbank and a German rap artist.
What is the flowering time of Herz OG?
Herz OG flowers in approximately 9 weeks indoors under a 12/12 light cycle. Outdoors, plants are ready for harvest around mid-October in a southern European climate.
How much does Herz OG yield indoors?
Expect 400–450 g/m² indoors with proper lighting and training. She's a medium yielder — not the heaviest producer, but the quality and resin coverage per gram more than compensate.
Is Herz OG suitable for beginners?
She's manageable but not the most forgiving strain. OG genetics can be sensitive to overwatering and calcium deficiency, especially in coco. If you've grown one or two runs before, you'll be fine. First-timers might want to start with something less finicky.
What does Herz OG smell and taste like?
Fresh pine, warm honey, and damp wood — classic OG terpenes with a sweeter, more layered profile than a standard Kush. The Larry OG parent adds a faint citrus note on the nose. Expect strong scent from week 6 of flower onwards; a carbon filter is essential.
How many seeds come in a pack of Herz OG?
Each pack contains 3 feminised seeds. All seeds are photoperiod, meaning they require a light cycle change to 12/12 to trigger flowering.
What's the difference between Herz OG and Herz OG Auto?
Herz OG is a photoperiod strain that needs a 12/12 light flip to flower. Herz OG Auto is an autoflowering version that flowers based on age, not light schedule. The photoperiod version typically produces higher yields and allows more control over veg time.
