Double OG Haze Feminised Cannabis Seeds by Pyramid Seeds
Double OG Haze is a feminised indica-dominant cannabis seed strain from Pyramid Seeds that delivers a heavy, full-body stone backed by up to 24% THC. Built from a three-way cross of Big Bud, Afgoo, and SFV OG, she's bred for maximum resin production, dense flowers, and a terpene profile that leans citrus-spicy with earthy undertones. Not a daytime strain — not even close. This is the one you reach for when the day is done and you want to melt into the sofa for a few hours.
Double OG Haze Genetics and Terpene Profile
The lineage here tells you everything you need to know about what Pyramid Seeds were aiming for. Afgoo — a cross of Afghani and Maui Haze — brings the extreme indica dominance and that deep, sedating body effect. Big Bud contributes yield potential and bud density. SFV OG (San Fernando Valley OG) rounds things out with a citrus-forward terpene profile and structural stability. The result after several generations of selective crossbreeding is a stable cultivar that leans heavily indica while retaining just enough sativa influence to keep the experience interesting.
Crack open a cured bud and you'll pick up on the terpenes straight away — a sharp citrus note hits first, followed by a spicy, almost peppery undertone and a base of damp earth. The kind of smell that fills a room and lingers on your fingers. If you're into strains with a complex nose, Double OG Haze delivers without being overwhelming.
Growing Double OG Haze — What to Expect
Double OG Haze feminised seeds are straightforward to grow, though the high THC content and dense bud structure mean you'll want to pay attention to airflow during flowering. She finishes in roughly 65 days indoors, which is fairly standard for an indica-dominant hybrid. Indoor yields sit around 400g/m² — respectable, especially considering the potency packed into each flower. The buds themselves are on the smaller side, but they're rock-hard and absolutely caked in trichomes.
Outdoors is where she really stretches her legs. Expect 750–1,000g per plant under good conditions. That's a serious harvest from a single specimen. She responds well to topping and low-stress training, which helps manage the canopy and expose lower bud sites to light. If you're growing in a tent, an 80x80cm space with decent ventilation and a carbon filter will serve you well — the smell gets loud in the final weeks of flower.

Double OG Haze Effects — Honest Take
This is a heavy hitter. At up to 24% THC, Double OG Haze sits comfortably in the upper range of potency. According to research published in the Journal of Analytical Toxicology, blood THC concentrations peak within 30 minutes after cannabis administration and return to baseline within 3 to 4 hours (Spindle et al., 2019). With a strain this strong, that peak hits fast and hard — a full-body wave that starts behind the eyes and rolls downward.
The effect is firmly physical. Expect heavy limbs, a warm sense of relaxation, and a strong pull toward the horizontal. There's a creative spark in the first 30 minutes or so — enough to enjoy music, a film, or a conversation — but the indica genetics win out eventually. This is an evening strain, full stop. If you smoke this before noon, you're writing off the rest of your day.
One honest limitation: the munchies are real. Afgoo is known for it, and the trait carried through to Double OG Haze. Have snacks ready or you'll end up ordering something regrettable at 11pm. Also, at 24% THC, newcomers should genuinely approach with caution. A single hit from a joint or vaporiser is enough to gauge your tolerance before committing to a full session.
Why Double OG Haze Stands Out
We've carried a lot of Pyramid Seeds strains over the years, and Double OG Haze is one of those cultivars that punches above its weight class. The combination of Big Bud's yield genetics with Afgoo's sedating power and SFV OG's terpene complexity creates something that's more than the sum of its parts. Compared to a straightforward OG Kush, Double OG Haze delivers a heavier body effect with more aromatic complexity. Compared to a pure Afghani, she's more interesting to grow — better structure, more resin, and a flavour profile that goes beyond simple earthy hash notes.
The 65-day flowering period is also worth noting. Some indica-dominant strains with similar THC levels push 9–10 weeks. Getting this level of potency in just over 9 weeks is efficient, and the outdoor yield potential of up to 1,000g per plant makes her one of the more productive options in the Pyramid Seeds catalogue.
The one thing to watch: bud density. Those tight, compact flowers look gorgeous, but they're also a magnet for mould if your humidity creeps above 50% in late flower. Good airflow and a dehumidifier aren't optional — they're the difference between a successful harvest and heartbreak.
How to Grow Double OG Haze Feminised Seeds
- Germinate your Double OG Haze seeds using the paper towel method or directly in a starter plug. Keep the environment warm (22–25°C) and moist until taproots emerge, typically within 48–72 hours.
- Transplant seedlings into their final containers once the first set of true leaves appears. A 15–20 litre pot works well for indoor grows. Use a well-draining medium — coco-perlite mixes or a quality organic soil both perform.
- Maintain an 18/6 light cycle during vegetative growth. Double OG Haze responds well to topping after the 4th or 5th node. Low-stress training helps open up the canopy and maximise light penetration to lower bud sites.
- Flip to 12/12 when plants have filled roughly 60–70% of your grow space. She'll stretch moderately during the first two weeks of flower.
- During flowering, keep relative humidity below 50% and ensure strong airflow around the canopy. The dense bud structure makes this strain susceptible to mould in stagnant, humid conditions.
- Gradually increase nutrient strength through mid-flower, then begin flushing 10–14 days before harvest. Trichomes should appear mostly milky with some amber — typically around day 65 of flower.
- Harvest, trim, and hang-dry in a dark room at 18–20°C and 55–60% humidity for 7–10 days. Cure in glass jars for at least two weeks to bring out the full citrus-spicy terpene profile.
Growing Double OG Haze indoors? A Dark Box grow tent paired with a carbon filter keeps the smell contained — and with this strain, you'll need it. If you're looking for a complementary evening strain with a different flavour profile, Pyramid Seeds' Tutankhamon offers a more citrus-forward experience at similar THC levels.

Frequently Asked Questions
Is Double OG Haze suitable for beginner growers?
Yes, she's reasonably forgiving. The main thing to watch is humidity during late flowering — those dense buds can trap moisture. Keep airflow strong and humidity below 50% in the final weeks, and you'll be fine. The 65-day flowering period is predictable, which helps newer growers plan their harvest.
How strong is Double OG Haze compared to other indica strains?
At up to 24% THC, she's in the upper tier. Most standard indica strains sit in the 15–20% range. The Afgoo parentage adds a particularly heavy body effect that hits faster than many comparable strains. Experienced smokers will appreciate the intensity; newcomers should start with a single hit and wait.
What does Double OG Haze smell and taste like?
The dominant notes are citrus and spice, with an earthy base. Think sharp lemon peel over cracked black pepper and damp soil. The flavour follows the nose closely — citrus on the inhale, spice and earth on the exhale. Curing for at least two weeks in glass jars brings out the full terpene complexity.
Can I grow Double OG Haze outdoors in a cooler climate?
She prefers warmth, but the 65-day flowering period means she can finish before autumn rains set in across most of northern Europe. In a cooler climate, aim for a south-facing spot with maximum sun exposure. The outdoor yield potential of 750–1,000g per plant assumes good conditions — expect less in shorter summers.
How many seeds come in a pack of Double OG Haze?
Each pack contains 5 feminised seeds. All seeds are photoperiod, meaning you'll need to switch to a 12/12 light cycle to trigger flowering indoors. Outdoors, she'll flower naturally as daylight hours decrease in late summer.
Is Double OG Haze a good strain for making concentrates?
The high THC content and heavy trichome production make her a solid candidate for extractions. The small, dense buds are particularly well-suited to dry sifting or bubble hash. The citrus-spicy terpene profile carries through into rosin and other solventless concentrates nicely.
