Herz OG Auto

Herz OG Auto Cannabis Seeds by Exotic Seed

Herz OG Auto is an autoflowering feminised cannabis seed from Exotic Seed that delivers near-photoperiod potency in a fast, compact plant. Created by crossing the original Herz OG with an autoflowering Gorilla Glue #4 and Black Lemon Auto, this strain packs a woody, pine-and-honey aroma into dense, resinous buds — and she's done in about 8–9 weeks from germination. If you've written off autos as lightweight, this one might change your mind.

Why Herz OG Auto Seeds Stand Out

Autoflowers have come a long way since the early days of scraggly Lowryders, and Herz OG Auto is a good example of where the genetics are now. Exotic Seed didn't just slap a ruderalis cross onto their Herz OG and call it done — they brought Gorilla Glue #4 auto and Black Lemon Auto into the mix, which shores up both resin production and structural integrity. The result is a plant that actually looks and smells like her photoperiod parent.

What we'd flag as genuinely impressive: the bud-to-leaf ratio. You're not trimming for hours to find the flower underneath. The buds come out medium-sized but properly dense and caked in trichomes. If you're into making hash or running extracts, that resin coverage is exactly what you want. She's also a strong candidate for dry herb vaporisers — the terpene profile really comes through at lower temperatures.

The honest limitation? She tops out at about 100cm. That's actually a feature for most indoor growers and anyone doing a guerrilla grow outdoors, but if you're chasing massive Christmas-tree plants, this isn't the genetics for that. What she lacks in stature she makes up for in yield density — we've seen reports of 400–500g per square metre indoors, which is strong for an autoflower of this size.

Herz OG Auto Aroma, Flavour, and Effect

Crack open a cured bud and you'll get a hit of fresh pine layered over a woody, almost cedar-like base. There's a sweetness in there too — a distinct honey note that rounds out the sharper terpenes and makes the whole profile feel more complex than you'd expect from an auto. It's the kind of jar you keep opening just to smell.

The smoke follows the nose closely. Woody and resinous on the inhale, with that pine sharpness, then the honey sweetness lingers on the exhale. Through a vaporiser at around 185–190°C, the honey note becomes even more pronounced.

Effect-wise, Herz OG Auto leans towards the body. The physical side is deeply relaxing — proper couch-lock territory if you overdo it. But there's a clear-headed, uplifting mental component layered on top that keeps things from feeling sedated. It's a balanced combination that works just as well on a lazy afternoon as it does in the evening. Medium-high potency means you still feel it properly, but you're not staring at the wall for three hours wondering where your thoughts went.

How to Grow Herz OG Auto Seeds

1. Germinate your Herz OG Auto seeds using the paper towel method or by placing them directly into a small pot of moist, airy soil. Taproots typically emerge within 24–72 hours.
2. Plant the germinated seed about 1cm deep in its final container. Autoflowers don't love being transplanted — starting in the final pot (11–15 litres for indoor, up to 20 litres for outdoor) avoids root stress and keeps the clock running smoothly.
3. Provide 18–20 hours of light per day throughout the entire lifecycle. Herz OG Auto doesn't need a light schedule change to flower — she'll start on her own around week 3–4. A quality LED or 400W HPS covers a 1m² canopy nicely.
4. Keep feeding light during the vegetative stretch, then increase phosphorus and potassium once you see flower sites forming. She's not a heavy feeder, so err on the side of less rather than more — overfeeding autos is one of the most common mistakes we see.
5. Monitor humidity closely once buds start fattening. Those dense, resin-heavy flowers are exactly the type that can develop mould if relative humidity creeps above 50% in late flower. Good airflow and a small dehumidifier go a long way.
6. Harvest when trichomes shift from clear to mostly milky with a few amber heads — typically around 8–9 weeks from germination. The dense bud structure means a slightly longer dry (10–14 days at 15–18°C, 55–60% RH) will reward you with a smoother, more flavourful end product.

Herz OG Auto vs Other Autoflowering Strains

The autoflower market is crowded, so here's where Herz OG Auto actually sits. Compared to something like a standard Gorilla Glue auto, Herz OG Auto brings a more complex terpene profile — that honey note is distinctive and not something you find in most GG crosses. The potency is in the same ballpark, but the effect balance tilts more towards physical relaxation rather than the heavier, sometimes couch-melting GG character.

Against a typical OG Kush auto, Herz OG Auto tends to yield more and finishes in a similar timeframe. The OG Kush autos we've seen usually run a bit taller but produce less dense buds. If yield per square metre matters to you, Herz OG Auto is the stronger pick.
