👑 Godfather OG Seeds: The Don of All OGs

Godfather OG is the strain that earned the nickname The Don of All OGs: a 2013 High Times Cannabis Cup winner for Best Indica, and one of the heaviest indicas you can grow.

The XXX OG × Alpha OG cross was developed in Southern California, stacking two potent OG Kush derivatives into a 60/40 indica-dominant hybrid that delivers one of the heaviest body effects in the catalogue. At typical grows it tests 22 to 28% THC. The 34% figure that follows the strain around came from a single exceptional competition sample rather than an average grow, but even the realistic range sits among the highest real-world THC levels you will find anywhere, and among the strongest options in our high-THC range.

One thing is worth knowing before you buy: multiple versions of Godfather OG exist under the same name. The Cup-winning original is the XXX OG × Alpha OG cross associated with Alpha Medic Inc. in Southern California. Other breeders have released their own Godfather OG lines using different parents, including crosses involving Bubba Kush, LA Confidential, and Granddaddy Purple. Quality and characteristics vary between versions. The version we stock is the XXX OG × Alpha OG lineage, the one with the award pedigree.

What those genetics produced:

• XXX OG: a heavy indica cross of XXX and OG Kush, itself a Cannabis Cup winner. Known for exceptional resin production, high THC, and a classic earthy-pine OG terpene profile with dense, frosty flowers
• Alpha OG: a hunted OG Kush phenotype developed by Alpha Medic Inc., the same California collective behind Godfather OG. Runs around 25% THC with classic OG terpenes and a deeply relaxing body effect
• The result: two OG Kush derivatives stacked on each other, producing a compound potency and resin output beyond what either parent reaches alone

What you get today is dense, compact flowers with bright green colouration, large calyxes, and purple hairs showing through generous trichome coverage. The aroma is unmistakably OG: earthy pine with grape undertones and a diesel finish, loud and deep. The buds are heavy with resin, which makes Godfather OG one of the better extract strains in the catalogue alongside its considerable potency as flower.

👑 Godfather OG Effects and Experience

Godfather OG sits at the heavy end of the indica-dominant spectrum, and the effect arc makes that obvious within minutes.

Onset (10–15 minutes): Faster than most indicas, since the high THC means Godfather OG arrives before you have fully settled. An immediate cerebral rush brings euphoria and a warm happiness. Thoughts brighten and laughter comes easily. This window is brief.

Early phase (15–40 minutes): The indica genetics assert themselves rapidly. Body relaxation begins spreading through the limbs, not gradually but in waves. Muscle tension releases. Mental clarity decreases while the euphoric quality remains. Motivation for anything active drops to near zero.

Mid-phase (40–90 minutes): Full body relaxation, and this is what Godfather OG is known for: a complete, deep, whole-body settle that removes tension and mental noise at once. The couch is not just appealing, it is the only reasonable option. The myrcene-dominant terpene profile amplifies the heavy quality, which is part of why Godfather OG feels heavier than its THC percentage alone would suggest.

Late-phase (90–180 minutes): Deep relaxation and a natural drift toward sleep. Appetite increases strongly in this phase. The comedown is gradual rather than abrupt. Morning grogginess is possible at higher doses but not typical at moderate consumption.

Duration: 3 to 5 hours at typical doses, longer than most strains at equivalent consumption. The high myrcene content extends the body effect.

Potency consideration: This is a strain that warrants genuine respect even from experienced users. The fast onset combined with high THC makes it easy to overconsume before the full effect establishes, so start lower than you think you need. The 22 to 28% range means phenotypic variation is real: some plants run toward the lower end, some toward the upper. Either way, this is not an approachable strain for cannabis newcomers.

Flavour profile: Earthy pine on the inhale with spicy grape and diesel undertones. The myrcene base gives it a musky, herbal depth. The grape note, which comes through more clearly in the flavour than the aroma, is a distinguishing characteristic. On a proper cure the complexity increases: woody undertones emerge alongside the pine, and the grape sweetens slightly. A classic OG profile, elevated by the compound genetics.

Common uses (anecdotal): End-of-night relaxation, evening wind-down, and a natural lead-in to sleep. This is not a daytime or functional strain. As with any high-potency strain, start with a small amount and go slowly.

🧪 Terpene Profile

The nose is classic OG: earthy pine over spicy grape and diesel. The chemistry behind it:

• Myrcene (dominant): the musky, herbal foundation, and the terpene most responsible for the heavy body settle. It also helps THC cross the blood-brain barrier, part of why Godfather OG punches above its number
• Caryophyllene: the peppery, diesel edge, and the one terpene that directly activates CB2 receptors, adding to the body effect through a separate pathway
• Limonene: the brighter note behind the grape sweetness on the exhale

A touch of pinene rounds out the earthy-pine top note. For how these compounds shape flavour and effect, see our cannabis terpenes guide.

🌱 Growing Godfather OG Seeds in Australia

(The following is provided for ACT licence holders and growers in legal jurisdictions overseas.)

Experience level required: Intermediate to experienced. Godfather OG is not especially difficult to grow, since the OG Kush genetics are reasonably forgiving with good pest and mould resistance, but it rewards experience. The environmental sensitivity, particularly temperature and humidity, and the need for proper training to manage the compact-but-branchy structure are where a newer grower can come unstuck. The dense bud structure needs careful humidity management in late flower. This is not a strain to run as your first grow. For the early weeks, our cannabis seedling care guide covers the watering and feeding that set the plant up well.

Best growing environments: Indoor under controlled conditions is where Godfather OG excels, because the ability to manage temperature and humidity precisely matters with this strain. Outdoor growing works well in warm Australian climates: Mediterranean-style conditions in WA, SA, and inland NSW suit it best. The dense buds are vulnerable in humid coastal environments without good airflow.

Flowering time: 8 to 9 weeks from the 12/12 flip, most phenotypes finishing around 8.5 weeks. Check trichomes from week 7. At 30% amber you are getting the full body effect, while harvesting earlier gives a slightly more functional high with less sedation. Do not let it run too long, since over-ripeness dulls the grape and pine terpenes. Our amber trichomes guide covers reading them.

Total grow time:

• Standard indoor: 4–6 weeks veg plus 8–9 weeks flower, 12–15 weeks total
• SOG: 2–3 weeks veg plus 8 weeks flower, 10–11 weeks total
• Outdoor: 8–12 weeks veg plus 8–9 weeks flower, 16–21 weeks total

Height and structure: Medium and compact indoors, typically 80 to 100 cm when flipped at 40 to 50 cm. The OG structure is bushy with multiple lateral branches and good bud-site density. Outdoor plants with extended veg can reach 150 to 180 cm. Early-flower stretch is moderate at 40 to 60%, manageable in standard tent heights with proper veg timing.

Training strategies:

SOG (Sea of Green): Excellent for Godfather OG. The compact, bushy OG structure produces well in SOG layouts with 9 to 16 plants per m². Short veg of 2 to 3 weeks, flip early, harvest frequently. The combination of fast cycling and solid yield per m² makes SOG the most efficient approach.

SCROG (Screen of Green): Also effective. The branching structure fills a net well with 4 to 5 weeks of veg, for good yield and canopy evenness with fewer plants than SOG.

Topping: Recommended for single-plant or SCROG grows. Top once or twice in veg to develop lateral branching and even the canopy. Godfather OG recovers well from topping, typically within 4 to 5 days.

LST: Works well alongside topping. Tie down branches to open the canopy and maximise light exposure across the bushy structure.

Feeding strategy: Godfather OG has moderate-to-generous nutrient requirements. The high resin production in flower benefits from phosphorus and potassium support. The strain is moderately sensitive to overfeeding, so watch the tips and back off if browning appears.

Vegetative phase:

• Start at 1/2 strength for the first 2 weeks, build to 3/4 by week 3, full by week 5
• EC range 1.4–1.8 in hydro or coco
• Moderate nitrogen, watching for dark green, clawed leaves
• CalMag beneficial in coco or with RO water

Early flower (weeks 1–3):

• Transition nutrients, reducing nitrogen and building phosphorus and potassium
• EC range 1.6–2.0
• Resin production begins early, so add phosphorus support from week 2 of flower

Mid-late flower (weeks 4–8):

• Peak feeding for bud density and trichome development
• EC range 1.8–2.4, since this strain handles slightly higher EC than more sensitive genetics
• A potassium boost supports the heavy resin and terpene production

Final flush (last 10–14 days):

• Plain pH-adjusted water only
• The grape and pine terpene profile is cleaner after a proper flush, which matters for both flavour and smoothness at this potency level
• Natural leaf yellowing is expected and desired

Climate requirements:

Temperature:

• Vegetative: 22–27 °C (lights on), 18–20 °C (lights off)
• Flowering: 20–25 °C (lights on), 17–19 °C (lights off)
• Keep below 28 °C, since above that resin production slows and THC potential drops
• Cool nights of 16–18 °C in the final 2 weeks enhance purple colouration and terpene expression

Humidity:

• Vegetative: 50–60% RH
• Early flower: 45–50% RH
• Mid-late flower: 40–45% RH, with strict management essential given the dense bud structure
• Do not exceed 50% RH from week 4 of flower, as bud rot risk is real in these conditions

Airflow:

• Critical, since the compact, dense OG structure restricts airflow through the canopy
• Oscillating fans directed at the canopy plus strong extraction
• Moderate defoliation in early flower improves airflow, so remove leaves blocking bud sites at the flip and again at week 3

Common issues:

Bud rot: The main risk. The dense flowers trap humidity without adequate airflow. Prevention through strict humidity management and canopy defoliation is far easier than managing rot once established. Check bud sites from week 5 onward, paying particular attention to large colas where airflow is most restricted.

Temperature sensitivity: Godfather OG's terpene and resin production is affected by temperature more noticeably than most strains. Keeping the grow room consistently in the 20 to 25 °C range in flower is not optional, since swings above 28 °C visibly affect the final product.

Harvest timing: Do not over-ripen. The pine and grape terpenes degrade past the optimal harvest window. Aim for 30% amber for the full body effect but check regularly from week 7.

Hash and concentrate production: Godfather OG is excellent for solventless extraction. The trichome density from the compound OG genetics makes bubble hash, dry sift, and rosin highly productive. If producing concentrates, harvest at 20 to 25% amber to preserve terpene quality.

🏠 Indoor Growing (Australia)

• Flowering time: 8–9 weeks under 12/12, most phenotypes finishing at 8.5 weeks
• Yield: 450–550 g/m² under quality lighting with SOG or SCROG
• Recommended veg period: 2–3 weeks for SOG, 4–6 weeks for SCROG or single large plants
• Height management: compact indoors, rarely a concern with standard tent heights
• Cycles per year: 4–5 complete SOG cycles annually with 8-week flower and 2–3 week veg
• Container size: 7–10 L for SOG, 12–18 L for SCROG or single plants
• Training recommendation: SOG is optimal, SCROG works well, and LST and topping are effective for single large plants
• Temperature: keep lights-on temperature consistently below 25 °C, since this strain's resin production is genuinely temperature-sensitive

🌿 Outdoor Growing (Australia)

• Harvest windows by region: Queensland and Northern NSW late March, Central NSW and ACT early to mid-April, Victoria and SA mid-April, Western Australia early to mid-April (Perth area), Tasmania mid-April (the 8 to 9 week flower works in Tasmania's timeframe, but watch for autumn cold snaps)
• Yield: 500–650 g per plant with a full season, one of the stronger outdoor yields in the OG category
• Planting timing: late October to early November, after frost risk passes
• Climate suitability: WA, SA, and inland NSW are ideal, since warm, drier conditions suit the dense bud structure. Coastal Queensland and NSW need careful airflow management around the buds from late February onward. Our Australian climate strain guide breaks this down by region
• Purple expression: run cool overnight temperatures in March (16–18 °C) and Godfather OG develops genuine purple and blue hues in the buds that contrast against the orange hairs and trichome frost
• Height: outdoor plants can reach 150 to 180 cm with extended veg, so stake the main stem and support heavy branches from week 5 of flower
• Pest management: good natural resistance to pests and mould, but the dense buds are not immune to bud rot in sustained humidity. Inspect weekly from week 5 of flower

❓ Frequently Asked Questions: Godfather OG Seeds

What is Godfather OG and why is it called The Don of All OGs?

Godfather OG is an indica-dominant hybrid (XXX OG × Alpha OG) bred in Southern California that won 1st Place Best Indica at the High Times Cannabis Cup in Los Angeles in 2013. The name also became shorthand for raw potency when a competition sample recorded a record 34.04% THC on High Times' Strongest Strains on Earth list in 2017. The Don of All OGs nickname reflects both the award pedigree and the potency: it is an OG Kush derivative stacked on another OG Kush derivative, producing a compound effect that goes beyond either parent.

Does Godfather OG really test at 34% THC?

One exceptional sample under optimal conditions recorded 34.04% in a lab test, which is the figure that put the Godfather OG name on the High Times strongest-strains list in 2017. It is not a typical grow result. Real-world grows consistently produce 22 to 28% THC, with 24 to 26% the most common outcome for competent growers. That is still among the highest you will find in our high-THC range, but expecting 34% from a standard grow sets unrealistic expectations. Plan around 24 to 26%.

How strong are the effects?

Very strong, among the heaviest body effects in the catalogue. The myrcene-dominant terpene profile amplifies the effect, which is part of why Godfather OG feels heavier than its THC percentage alone would suggest. At moderate doses you get deep physical relaxation with an initial euphoric phase. At higher doses it is immediate couch-lock. This is not a functional evening strain, it is an end-of-night one.

How long does Godfather OG take to flower?

8 to 9 weeks from the 12/12 flip, with most phenotypes completing around 8.5 weeks. Check trichomes from week 7 and harvest at around 30% amber for the maximum body effect. The pine and grape terpenes degrade if the plant runs too far past the optimal window, so do not let it over-ripen. Our amber trichomes guide covers reading the signals.

What yields can I expect?

450 to 550 g/m² indoors under good lighting with SOG or SCROG. Outdoor plants in good conditions produce 500 to 650 g per plant. SOG is the most efficient technique for this strain, given the compact structure and fast 8-week flower.

Are there multiple versions of Godfather OG?

Yes, and this is worth understanding before purchasing from any seed bank. The original Cup-winning Godfather OG is the XXX OG × Alpha OG cross associated with Alpha Medic Inc. in Southern California. Multiple other breeders have released their own Godfather OG lines under the same name using different genetics, including crosses with Bubba Kush, LA Confidential, and Granddaddy Purple. Quality and characteristics vary between them. The version we stock is the XXX OG × Alpha OG lineage with the award pedigree.

Is Godfather OG difficult to grow?

Intermediate difficulty. The OG Kush genetics give it better-than-average pest and mould resistance, and the compact structure is manageable. The areas that need attention are temperature management in flower (keep below 25 °C, since the terpene and resin production are genuinely temperature-sensitive), humidity management in late flower (the dense buds need airflow and RH below 45% from week 4), and harvest timing (do not over-ripen, and check trichomes from week 7). Outside of these points, it grows predictably and rewards standard training techniques.

Is Godfather OG good for hash and concentrates?

Excellent, one of the better extract strains in the catalogue. The compound OG genetics produce trichome density that is above average even by high-THC standards. Bubble hash, dry sift, and rosin all return strong yields. For concentrate production, harvest at 20 to 25% amber rather than the full 30% to preserve terpene quality in the extract. The grape and pine profile translates well into rosin, smooth and distinctively flavoured.

What are the ideal growing conditions?

Temperature: 22–27 °C veg (day), 20–25 °C flower (day, keep below 25 °C), 17–19 °C nights, dropping to 16–18 °C overnight in the final 2 weeks for purple expression.
Humidity: 50–60% veg, 45–50% early flower, 40–45% mid-late flower, with strict management from week 4.
Light cycle: 18/6 veg, 12/12 to flower.
pH: 6.0–6.5 soil, 5.5–6.0 coco or hydro.
EC: 1.4–1.8 veg, 1.8–2.4 flower, handling slightly higher EC than more sensitive genetics.

What awards has Godfather OG won?

1st Place Best Indica at the High Times Cannabis Cup in Los Angeles in 2013, won with the XXX OG × Alpha OG version associated with Alpha Medic Inc., the lineage we stock. Separately, the Godfather OG name topped High Times' Strongest Strains on Earth list in 2017 with a record 34.04% THC sample, which cemented the strain's wider reputation for potency.

How does Godfather OG compare to the auto version?

The Auto Godfather OG carries the same Cup-winning XXX OG × Alpha OG genetics on a fixed 70 to 75 day timeline that flowers without a light-schedule change. THC sits a little lower at 18 to 22%, and the plant stays compact and discreet. For maximum potency and yield the photoperiod is the definitive version. For stealth, balcony, or perpetual indoor grows, the auto is the practical pick.

How important is the cure for Godfather OG?

More than most. The grape and pine terpenes keep developing in the jar. Four weeks is the minimum for recognisable character, and 8 to 12 weeks is where the flavour fully opens up. Burp daily for the first two weeks, then a few times weekly. Our drying and curing guide covers the full process.

Does Godfather OG develop purple colouration?

Yes, reliably, one of the more visually striking finishes in the catalogue. The large calyxes develop purple and blue hues in late flower, particularly with cool overnight temperatures (16–18 °C) in the final two weeks. The colour contrasts against the bright orange hairs and the heavy trichome frost. Some phenotypes express darker than others, but all Godfather OG plants develop some purple colouration under cool conditions. Outdoor growers running March nights cool will see particularly strong expression before the April harvest.
