Auto King Kong Cannabis Seeds by Dr. Underground
Auto King Kong is an autoflowering cannabis seed from Dr. Underground that packs the genetics of their legendary King Kong strain into a fast-finishing, beginner-friendly format. Crossing King Kong (Ed Rosenthal Super Bud x Chronic) with a ruderalis variety, this slightly indica-dominant hybrid goes from seed to harvest in just 8–9 weeks — making it one of the quickest routes to generous yields you'll find in an auto seed.
Why Auto King Kong Seeds Deserve a Spot in Your Grow Room
Dr. Underground built their reputation on King Kong — it's been one of their flagship strains for years, and for good reason. The original is a proper heavy-hitter with Ed Rosenthal Super Bud and Chronic in its lineage. But the photoperiod version demands a bit more grow-room know-how: light schedule management, longer veg periods, the usual. Auto King Kong strips all that away. You plant it, give it light (18/6 or even 20/4), and roughly 8–9 weeks later you're trimming.
What makes this auto stand out from the sea of autoflowering seeds on the market is the yield. Most autos trade convenience for smaller harvests — that's the deal you accept. Auto King Kong pushes back against that compromise. Dr. Underground have managed to keep the generous production of the original while adding ruderalis genetics for that automatic flowering trigger. The plant stays at medium height, so it won't outgrow a standard tent, but it fills out properly with dense, resinous buds.
We've carried Dr. Underground seeds since the early days of their catalogue, and the King Kong line consistently gets reordered. That tells you something. If you want a perpetual harvest setup — staggering plants every 2–3 weeks so you've always got something drying — Auto King Kong is built for exactly that kind of rotation.
Aroma and Flavour Profile of Auto King Kong
Crack open a cured jar of Auto King Kong and the first thing that hits you is a thick, pungent incense note — almost resinous, like walking into a head shop in the late '90s. It fills a room quickly, so keep that in mind if discretion matters to you. A decent carbon filter is non-negotiable here.
On the smoke, that incense base gives way to bright citrus lemon flavours that cut through the heaviness, followed by skunky, earthy overtones that linger on the palate. It's a layered profile — not a one-note strain. The terpene combination leans towards that classic "old-school dank" character with enough citrus brightness to keep it interesting. If you've grown Chronic or Ed Rosenthal Super Bud before, you'll recognise the family resemblance, but Auto King Kong has its own personality.
Growing Auto King Kong Seeds — What to Expect
Auto King Kong is genuinely straightforward to grow, which is the entire point of an autoflowering seed. Here's what 8–9 weeks of growing this strain looks like in practice:
- Germinate your seeds using the paper towel method or directly in a small pot of moist soil. Taproots typically emerge within 24–72 hours.
- Transplant seedlings into their final container early — autos don't love being repotted mid-grow. An 11–15 litre pot works well for Auto King Kong's medium stature.
- Set your light schedule to 18/6 or 20/4 from day one and leave it there. No need to switch to 12/12 — the ruderalis genetics handle the flowering trigger automatically.
- Feed lightly during the first 2 weeks, then gradually increase nutrients as the plant enters vegetative growth. Auto King Kong responds well to a balanced NPK feed without heavy supplementation.
- Watch for pre-flowers around week 3–4. The plant will begin stretching and developing bud sites. This is where Auto King Kong starts to show its King Kong parentage — expect vigorous lateral branching.
- During weeks 5–8, buds fatten rapidly. Maintain good airflow around the canopy to prevent moisture buildup in those dense flower clusters.
- Check trichomes with a jeweller's loupe from week 8 onwards. Harvest when trichomes shift from clear to milky with a few amber heads — typically around week 8–9 from seed.
The honest limitation with Auto King Kong — and with any auto — is that you can't extend the vegetative phase if something goes wrong early on. If your seedling gets stressed in week 1 (overwatering, cold snap, transplant shock), you can't just give it extra veg time to recover. The clock is ticking from germination. So get your environment dialled in before you pop the seed, not after.

Auto King Kong vs. Photoperiod King Kong — Which Should You Grow?
If you've been eyeing the original King Kong from Dr. Underground, the decision comes down to what you value more: maximum yield potential or speed and simplicity.
| Feature | Auto King Kong | Photoperiod King Kong |
|---|---|---|
| Time to Harvest | 8–9 weeks from seed | ~10–12 weeks (plus veg time) |
| Light Schedule | 18/6 or 20/4 throughout | 18/6 veg, 12/12 flower |
| Yield Potential | Generous for an auto | Higher overall |
| Grow Difficulty | Beginner-friendly | Intermediate |
| Perpetual Harvest | Easy — stagger every 2–3 weeks | Requires separate veg/flower spaces |
| Training Tolerance | LST only (no time for high-stress) | Topping, FIM, SCROG all viable |
We'd pick Auto King Kong if you're growing in a single tent and want a constant rotation of fresh bud without managing separate light schedules. The photoperiod version is the better choice if you've got the space and experience to push yields to their absolute ceiling. Both carry that same incense-and-citrus King Kong character — you're not sacrificing flavour or potency by going auto.
Running Auto King Kong in a tent? Pair it with a complete grow kit that includes lighting, ventilation, and a carbon filter — you'll need the filter with this strain's pungent aroma. If you're germinating for the first time, a propagation kit with root stimulator gives your seedlings the strongest possible start during that critical first week when autos can't afford setbacks.
Who Should Grow Auto King Kong Seeds
Auto King Kong works best if you want reliable, fast results without babysitting a complicated grow schedule. New growers will appreciate the forgiving nature of autoflowering genetics — no light leak paranoia, no photoperiod management, no sexing plants (these are feminised). You plant, you water, you wait 8–9 weeks.
But it's not just a beginner's strain. Experienced growers use autos like Auto King Kong to fill gaps between photoperiod harvests or to run a dedicated perpetual setup. With a 2-seed pack, you can stagger your planting and have a rolling supply going. The medium height means it fits comfortably in a 60x60 or 80x80 tent without fighting for headroom.
The one scenario where we'd steer you elsewhere: if you're an advanced grower who wants to run aggressive training techniques like mainlining or heavy topping. Autos don't give you the recovery time for that. Stick to gentle LST (low-stress training) and let the plant do its thing. Dr. Underground's genetics are vigorous enough that Auto King Kong will fill out your canopy without needing much intervention.
Frequently Asked Questions
Is Auto King Kong indica or sativa?
Auto King Kong is a slightly indica-dominant hybrid. Its genetics come from King Kong (Ed Rosenthal Super Bud x Chronic) crossed with a ruderalis variety. The indica lean shows in its medium height and dense bud structure, while the sativa side of its lineage contributes to an uplifting, heady character.
How long does Auto King Kong take from seed to harvest?
Roughly 8–9 weeks from germination to harvest. That's the full lifecycle — no separate veg and flower phases to manage. Some phenotypes may run a few days longer, so always check trichome colour with a loupe before chopping.
What yields can I expect from Auto King Kong?
Dr. Underground describes the yields as very generous for an autoflowering strain. Exact grams depend on your setup — lighting, pot size, and nutrients all play a role. In an 80x80 tent with decent LED lighting and 11–15 litre pots, you'll get a satisfying harvest from each plant.
What does Auto King Kong smell and taste like?
Expect a thick, pungent incense aroma that fills any room quickly. The flavour opens with citrus lemon notes and finishes with skunky, earthy overtones. A carbon filter is strongly recommended — this strain is not subtle.
Can I grow Auto King Kong outdoors?
Yes. Autoflowering seeds don't depend on a specific light cycle to flower, so Auto King Kong will perform outdoors in most climates as long as it gets enough direct sunlight. The 8–9 week lifecycle means you can fit multiple runs into a single outdoor season in warmer regions.
How many seeds come in a pack of Auto King Kong?
Each pack contains 2 feminised autoflowering seeds. They're feminised, so every seed should produce a female plant — no males to cull.
What terpenes are in Auto King Kong?
Dr. Underground doesn't publish a specific terpene profile, but the aroma and flavour point to a combination of myrcene (earthy, musky), limonene (citrus lemon), and caryophyllene (spicy, peppery). The incense character likely comes from a terpinolene or linalool presence as well.
Do I need to change the light schedule for Auto King Kong?
No. That's the beauty of autoflowering genetics. Set your lights to 18/6 or 20/4 from day one and leave them. The ruderalis genetics trigger flowering automatically based on the plant's age, not the light cycle.
