Tangerine G13 Cannabis Seeds
Tangerine G13 is a feminised cannabis seed strain by Amsterdam Genetics that crosses the fruity Tangerine sativa with the legendarily potent G13 indica. The result is a 60/40 indica-sativa hybrid carrying around 20% THC, a flowering time of 9-10 weeks, and yields that reach 500g/m² indoors. If you want citrus-drenched flavour backed by serious potency, this is one of Amsterdam Genetics' strongest offerings.
How Many Seeds Do You Need?
Tangerine G13 feminised seeds come in packs of 3, 5, or 10. If you're running a single tent with a 600W light, 3-5 seeds gives you a comfortable selection — pop them all, keep the strongest phenotypes, and you'll fill a square metre nicely. Going for a SOG setup or want to pheno-hunt? Grab the 10-pack. Every seed is feminised, so no males to cull.
| Pack Size | Best For |
|---|---|
| 3 seeds | Single grow, limited space, first-time growers |
| 5 seeds | Standard tent run, room to pick the best phenotype |
| 10 seeds | SOG setups, pheno-hunting, or stocking up |
Tangerine G13 Genetics and Flavour Profile
The Tangerine parent brings a wave of sweet citrus and tropical fruit that hits you the moment you crack a jar open. Think ripe mandarin peel with a sugary undertone — not subtle, not shy. The G13 side is the muscle: a near-mythical indica that's been circulating since the 1980s, rumoured to have originated from a US government research facility (take that with a grain of salt, but the potency is very real). Amsterdam Genetics crossed these two to create a strain that smells like a fruit bowl but smokes like a heavyweight.
The flavour on exhale is where Tangerine G13 really shines. Sweet, fruity, and distinctly citrus — it coats the palate in a way that makes you want another pull. If you've grown or smoked Tangerine Dream by Barney's Farm, you'll recognise that same tangerine backbone, but G13 adds a deeper, earthier body to the smoke. It's richer, denser, and the indica influence rounds out the sweetness so it doesn't veer into candy territory.
Growing Tangerine G13 Feminised Seeds
Tangerine G13 feminised seeds produce plants with noticeable sativa stretch during early flower, which makes her a strong candidate for ScrOG (Screen of Green) training. That 40% sativa genetics means she'll push through a screen with vigour, filling out a canopy evenly without too much coaxing. For growers who prefer a faster turnaround, SOG (Sea of Green) works well too — shorter veg time, more plants per square metre, and you still capitalise on her natural branching.
Indoors, expect heights of 120-150cm. That's manageable in most tents without aggressive topping, though a little LST (low-stress training) in veg will pay dividends come harvest. Under a 600W HPS or equivalent LED, Amsterdam Genetics reports yields up to 500g/m² — a solid return for a 9-10 week flowering period. We'd say that's realistic if your environment is dialled in: consistent temps around 24-26°C, humidity dropping to 40-45% in late flower, and proper airflow through the canopy.
Outdoors, she's a different beast entirely. Given enough sun and a long enough season, Tangerine G13 can stretch to 250cm and deliver up to 600g per plant. Those buds grow light green, very compact, and absolutely caked in resin by harvest time. If you're in a Mediterranean or similarly warm climate, she'll thrive. Northern European growers — keep an eye on your autumn weather. A 10-week flower means you're harvesting in mid-to-late October, and damp conditions plus dense buds are an invitation for mould. Good airflow and a dry spell at the right time make all the difference.

What to Expect from Tangerine G13
At 20% THC, Tangerine G13 doesn't mess around. The indica dominance delivers a deep, full-body relaxation that settles into your limbs and stays there. But the 40% sativa genetics keep the lights on upstairs — there's an uplifting, clear-headed quality that prevents you from sinking entirely into the sofa. It's that balance that won this strain its awards: you get the physical calm without the mental fog.
The onset is fairly quick. Within a few minutes you'll notice the body effect building, and the sativa side tends to arrive as a gentle lift in mood that sits on top of the physical relaxation. It's the kind of smoke that works just as well at the end of a long day as it does on a lazy afternoon. Not a "get things done" strain, but not a knockout either.
One honest note: at 20% THC, less experienced smokers should pace themselves. The fruity flavour makes it very easy to overdo it, and the indica body load can feel heavy if you've had more than you bargained for. Start with a small amount and give it 10-15 minutes before going back for more.
Why Tangerine G13 Over Other Citrus Strains
The citrus cannabis category is crowded. Tangerine Dream, Mimosa, Clementine — they all promise that sweet orange flavour. So why Tangerine G13? Two reasons: the G13 backbone and the growing characteristics.
Most citrus-forward strains lean sativa-dominant, which means longer flowering times, taller plants, and a more cerebral effect. Tangerine G13 flips that — the indica dominance keeps her compact (120-150cm indoors), the flowering time stays under 10 weeks, and the effect carries genuine physical weight. You get the flavour of a sativa with the grow profile and body effect of an indica. That's a combination that's harder to find than you'd think.
Compared to Amsterdam Genetics' own lineup, Tangerine G13 sits in the "flavour meets firepower" slot. If you want something with a similar potency but a completely different terpene profile, their White Choco or Milkshake Kush are worth a look. But if citrus is what you're after, Tangerine G13 is their best expression of it.
Complete your grow setup with a quality propagation kit to give these feminised seeds the best start. A heated propagator and root stimulator will speed up germination and give seedlings a strong foundation before they hit the tent. If you're planning a ScrOG run, pick up a trellis net — Tangerine G13's sativa stretch fills one out beautifully.
How to Germinate Tangerine G13 Seeds
- Drop your Tangerine G13 seeds into a glass of room-temperature water (around 20-22°C). Leave them in a dark spot for 12-24 hours. Most seeds will sink to the bottom once they've absorbed enough water — give any floaters a gentle tap.
- Transfer the seeds to damp paper towels on a plate. Fold the towels over so the seeds are sandwiched between moist layers. Cover with a second plate to create a dark, humid chamber.
- Check every 12 hours and keep the towels moist (not soaking). Within 24-72 hours, you should see taproots emerging — a white root tip poking out of the seed shell.
- Once the taproot is 1-2cm long, plant it root-down into your chosen medium (soil, coco, or a rockwool cube) at a depth of about 1cm. Keep the surface moist and the temperature around 22-25°C.
- Seedlings should break the surface within 2-4 days. Once the first set of true leaves appears, you can start a very light feeding schedule (quarter-strength nutrients). From here, Tangerine G13's sativa vigour kicks in — she'll grow quickly, so plan your training early if you're running ScrOG.
Frequently Asked Questions
Is Tangerine G13 indica or sativa?
Tangerine G13 is an indica-dominant hybrid: 60% indica and 40% sativa. The indica side comes from the G13 parent, while the Tangerine parent contributes the sativa genetics and the citrus terpene profile.
How long does Tangerine G13 take to flower?
Flowering time is 9-10 weeks from the start of the 12/12 light cycle. That's fairly quick for a strain with this level of potency and yield — most comparable hybrids run 10-12 weeks.
What yield can I expect from Tangerine G13 indoors?
Under a 600W light in a standard tent setup, Amsterdam Genetics reports up to 500g/m². Realistic yields for most home growers sit in the 400-500g/m² range, depending on training method and environmental control.
What does Tangerine G13 taste like?
Sweet, fruity, and unmistakably citrus — like biting into a ripe tangerine. The G13 parent adds an earthy depth on the exhale that keeps the flavour from being one-dimensional. It's one of the tastier strains in the Amsterdam Genetics catalogue.
Can I grow Tangerine G13 outdoors in northern Europe?
You can, but timing is tight. The 9-10 week flowering period means an October harvest, which puts you at risk of autumn rain and humidity. Dense buds plus damp weather equals mould risk. If your climate allows a dry October, she'll do well outdoors and can yield up to 600g per plant.
Is Tangerine G13 suitable for ScrOG growing?
Very much so. The 40% sativa genetics give her good lateral stretch and vigorous branching — exactly what you want filling a screen. Top her once or twice during veg, weave the branches through the net, and she'll reward you with an even, productive canopy.
How does Tangerine G13 compare to Tangerine Dream?
Tangerine Dream by Barney's Farm is sativa-dominant (60/40 sativa-indica), while Tangerine G13 flips that ratio to 60/40 indica-sativa. The flavour profiles share a citrus core, but G13 adds more physical weight to the effect and typically finishes flowering a week or two sooner.
