Sweet Mango Autoflowering Cannabis Seeds
Sweet Mango Autoflowering is a feminised autoflowering cannabis seed from Greenhouse Seeds that crosses Mango with Big Bang Autoflowering (Skunk x Northern Light x El Niño x Ruderalis). Nine weeks from germination to harvest, up to 700g/m² indoors — this is one of the most efficient autos we've come across for growers who want serious weight without serious waiting.
Choose Your Pack Size
Sweet Mango Autoflowering seeds come in packs of 3, 5, or 10. If you're running a test grow or have limited space, 3 seeds is enough for a single SOG tray. Go for 5 if you want to fill an 80x80 tent with room to select the best phenotypes. The 10-pack makes sense for commercial setups or anyone filling a full square metre — and the per-seed cost drops noticeably.

Running Sweet Mango Autoflowering in a tent? Pair it with a complete grow kit that includes lighting, ventilation, and a carbon filter — the fruity terpenes on this strain get loud in late flower, and your neighbours don't need to know about your hobby. A pH meter and CalMag supplement are also worth grabbing if you're growing in coco.
Why Sweet Mango Autoflowering Deserves a Spot in Your Grow Room
Most autoflowers ask you to compromise. You get speed, but you sacrifice yield. You get compact plants, but the buds are airy. Sweet Mango Autoflowering from Greenhouse Seeds doesn't play that game. At up to 700g/m² indoors, it out-yields plenty of photoperiod strains — and it does it in just 9 weeks from popping the seed. That's not a typo. Nine weeks, seed to chop.
The genetics behind this are solid. Mango brings the exotic terpene profile and resin production. Big Bang Autoflowering contributes the structural backbone — Skunk for vigour, Northern Light for density, El Niño for that extra frost, and Ruderalis for the autoflowering trigger. The result is a plant that stays between 70 and 100cm tall, branches out nicely without much training, and stacks buds that are almost all flower and barely any leaf. We've seen growers spend hours trimming other strains; with Sweet Mango Auto, post-harvest work is genuinely minimal.
The one thing to watch: because these plants stay compact and produce such dense buds, airflow matters. If you're growing in a humid climate or a tent without proper extraction, keep an eye on the lower canopy. A small oscillating fan pointed at the base of the plants goes a long way. Dense buds and stagnant air are not friends.
Growing Sweet Mango Autoflowering Seeds
We get asked about this strain regularly, and the feedback from growers is consistent: it's forgiving, it's fast, and it smells incredible in the final two weeks. That sweet, almost candy-like mango scent fills the room late in flower — unmistakable and genuinely pleasant compared to the skunky diesel that dominates most tents.
Sweet Mango Autoflowering works indoors and outdoors without fuss. Indoors, it's a natural fit for SOG (Sea of Green) setups — plant 9 to 16 per square metre, let them grow naturally, and the uniform height and branching structure will fill your canopy evenly. For ScrOG growers, the branching responds well to being spread under a net, and the 70–100cm height means you're not fighting a plant that wants to stretch into your light.
Outdoors, expect 60–80 grams per plant. Not record-breaking numbers, but for a 9-week auto that doesn't need light-cycle management, it's solid. Plant in late spring and you'll be harvesting before most photoperiod growers have even flipped to flower. In northern European climates, you can comfortably run two outdoor cycles in a single season if you start the first batch in April.
How to Grow Sweet Mango Autoflowering
- Germinate your seeds using the paper towel method or directly in a small pot of moist, lightly fertilised soil. Tap roots typically appear within 24–72 hours.
- Transplant seedlings into their final container early — autos don't love being repotted. A 10–15 litre pot is the sweet spot for indoor grows. Outdoors, 15–20 litres gives the roots room to stretch.
- Provide 18–20 hours of light per day indoors. Since it's an autoflower, there's no need to switch to 12/12. Some growers run 20/4 from start to finish with good results.
- Keep feeding light during the first 2–3 weeks. Autoflowers are sensitive to overfeeding early on. Ramp up nutrients once you see vigorous vegetative growth and pre-flower sites forming.
- Expect pre-flowers around week 3–4. From here, the plant shifts energy into bud production rapidly. Switch to bloom nutrients and consider adding a PK booster in weeks 5–7.
- Monitor humidity closely once buds start fattening. Aim for 40–50% RH during late flower. The dense bud structure of Sweet Mango Auto holds moisture, so good airflow and extraction are critical.
- Flush with plain water for the final 5–7 days before harvest. Trichomes should be mostly milky with a few turning amber — that's your window for the relaxing, Indica-leaning effect this strain is known for.
- Trim, dry at 18–20°C with 55–60% humidity for 7–10 days, then cure in glass jars for at least 2 weeks. The mango terpenes develop beautifully during a proper cure.
Sweet Mango Auto vs Other Greenhouse Seeds Autoflowers
If you're comparing options within the Greenhouse Seeds catalogue, here's how Sweet Mango Autoflowering stacks up against two other popular autos from the same breeder.
| Trait | Sweet Mango Auto | Big Bang Auto | Super Critical Auto |
|---|---|---|---|
| Genetics | Mango x Big Bang Auto | Skunk x NL x El Niño x Ruderalis | Skunk x Big Bud x Ruderalis |
| Seed to Harvest | 9 weeks | 8–9 weeks | 8 weeks |
| Indoor Yield | Up to 700g/m² | Up to 500g/m² | Up to 550g/m² |
| Height | 70–100cm | 60–90cm | 70–100cm |
| Flavour | Sweet mango, fruity, sour | Earthy, spicy | Citrus, pine |
| Best For | Yield-focused growers who want exotic flavour | Beginners wanting a compact, easy grow | Fast turnaround with decent weight |
Sweet Mango Auto wins on yield and flavour. Big Bang Auto is the simpler, more compact option if you're just getting started. Super Critical Auto splits the difference — faster finish, slightly lower yield, more citrus-forward profile. We'd pick Sweet Mango Auto if maximising grams per square metre is the goal and you don't mind one extra week of patience.
Frequently Asked Questions
How long does Sweet Mango Autoflowering take from seed to harvest?
About 9 weeks from germination. That's the full cycle — no separate veg and flower phases to manage. Some phenotypes may finish a few days earlier or later depending on conditions, but 9 weeks is the reliable benchmark from Greenhouse Seeds.
What yield can I expect from Sweet Mango Autoflowering indoors?
Up to 700g/m² under optimised indoor conditions with strong lighting (400W+ HPS or equivalent LED). Outdoors, expect 60–80 grams per plant. These numbers assume healthy plants with proper nutrition and environmental control throughout the cycle.
Is Sweet Mango Autoflowering suitable for SOG or ScrOG?
Yes to both. The 70–100cm height and natural branching structure make it a strong candidate for either method. For SOG, plant 9–16 per square metre in smaller pots. For ScrOG, use fewer plants in larger containers and spread the branches under a net during early growth.
What does Sweet Mango Autoflowering smell and taste like?
Exactly what the name suggests — sweet mango with a fruity, slightly sour edge. The aroma intensifies significantly during the final two weeks of flower. Expect a room-filling tropical sweetness that's quite different from the typical diesel or skunk profiles. A carbon filter is strongly recommended for discreet grows.
How tall does Sweet Mango Autoflowering grow?
Between 70 and 100cm in most environments. She stays compact and manageable, which makes her a good fit for tents, small grow rooms, and balcony grows. You won't need to worry about height control techniques like super cropping or extreme LST.
Does Sweet Mango Autoflowering need a specific light schedule?
No. As an autoflower, she'll flower regardless of light cycle. Most growers run 18/6 or 20/4 from start to finish. There's no need to switch to 12/12, which is one of the key advantages of autoflowering genetics over photoperiod strains.
Is Sweet Mango Autoflowering hard to trim?
Not at all — it's one of the easier strains to process. The buds are dense and coated in resin, but they have very few small leaves mixed in. Greenhouse Seeds specifically notes that post-harvest work is minimal compared to leafier varieties. A quick dry trim is usually all you need.
