Speedy Chile Fast Flowering Cannabis Seeds
Speedy Chile Fast Flowering is a feminised photoperiod strain from Royal Queen Seeds that delivers 16% THC buds in just 6 weeks of flowering — making it one of the fastest photoperiod options we carry. Bred from Green Poison crossed with Chile Indica, it gives you autoflower-level speed without sacrificing potency or yield. If you've been eyeing autos but can't stomach the lower THC, this is your answer.
Pack Sizes
| Pack | Seeds | Best for |
|---|---|---|
| 1 seed | 1 | Single-plant test run or SOG slot |
| 3 seeds | 3 | Small tent, pick the best phenotype |
| 5 seeds | 5 | Standard indoor grow — room to select |
| 10 seeds | 10 | Full canopy or outdoor plot |
We'd go with 3 or 5 seeds for a first run — gives you pheno variation without committing your whole space to one strain.
Why Speedy Chile Fast Flowering Seeds Stand Out
The pitch is simple: photoperiod control with autoflower timelines. Most fast-flowering strains sacrifice something — usually potency, sometimes structure. Speedy Chile keeps its THC at 16% and produces dense, resinous buds that smell of earthy spice with a sweet undertone. The Chile Indica parentage gives it a compact, stocky frame that rarely exceeds 100 cm indoors, which means you can run it in a 60x60 tent without height stress.
Here's what we appreciate most: the 2-week vegetative period before you flip to 12/12. That's absurdly short for a photoperiod plant. You're looking at seed-to-harvest in roughly 8 weeks total if you push it — comparable to most autoflowers but with the ability to extend veg if you want bigger plants. Outdoors, the plants stretch to 130–160 cm and finish in September, which is critical if you're growing in Northern Europe where October rains destroy late-finishing strains.
The honest limitation: 16% THC won't blow the doors off if you're used to 25%+ strains. But that's actually a feature for a lot of growers — the effect is functional, relaxing without flattening you. Traditionally, Chile Indica genetics have been used for their body-focused properties, and that heritage shows here. You can smoke this in the evening and still hold a conversation.

How to Grow Speedy Chile Fast Flowering
- Germinate seeds using the paper towel method or directly in a small pot of lightly moistened seedling soil. Taproots typically emerge within 24–72 hours.
- Transplant seedlings into their final container once the first true leaves appear — 7–11 litre pots work well for the compact indoor frame. Going straight to final pot avoids transplant shock and keeps the tight timeline on track.
- Provide 18/6 light during the short vegetative phase (approximately 2 weeks). The plants stay compact, so you won't need heavy training — a light top or LST is enough if you want to open the canopy.
- Switch to 12/12 to trigger flowering. The 6-week bloom period is genuinely short, so keep your feeding schedule tight. Transition to bloom nutrients within the first week of flip.
- Watch trichome development from week 5 onwards. Speedy Chile finishes fast, and over-ripening can shift the effect profile more sedative than intended. Harvest when trichomes are mostly milky with just a few amber heads.
- Dry in a dark room at 18–20°C with 55–60% humidity for 7–10 days, then cure in glass jars for at least 2 weeks. The earthy, spicy terpene profile develops noticeably during cure.
Complete your setup with a propagation kit for reliable germination, and grab a jeweller's loupe or pocket microscope to nail the harvest window on this fast-finishing strain. For indoor grows, a compact grow tent in the 60x60 or 80x80 range suits Speedy Chile's height profile well.
Speedy Chile Flavour and Effect Profile
The buds carry a distinct earthy spice — think dried chilli flakes mixed with sweet pine. It's not the loudest-smelling strain in the jar, but the flavour translates well when smoked or vaporised. The Chile Indica genetics bring a warmth to the smoke that sits nicely in the throat without harshness.
Effect-wise, you're getting a body-focused relaxation with a mild, clear-headed uplift. It won't pin you to the sofa, but it takes the edge off physical tension. Traditionally, indica-dominant strains with this terpene profile have been used for evening relaxation and appetite stimulation. The 16% THC level keeps things manageable — you can function, have dinner, watch a film, and drift off naturally.
Frequently Asked Questions
Is Speedy Chile Fast Flowering an autoflower or photoperiod?
It's a feminised photoperiod strain — you control flowering by switching to a 12/12 light cycle. The "fast flowering" label refers to its unusually short 6-week bloom period, not autoflowering genetics. You still need to manage light schedules.
How long does Speedy Chile take from seed to harvest?
Approximately 8 weeks total: 2 weeks vegetative growth plus 6 weeks of flowering. Add a week for drying and you're looking at finished, smokeable bud in roughly 9 weeks from germination.
What yield can I expect from Speedy Chile indoors?
Royal Queen Seeds rates it at 475–525 g/m² indoors. In a 60x60 tent with proper lighting and nutrition, expect the lower end of that range. An 80x80 or larger with good light penetration will push you toward the upper figure.
Can I grow Speedy Chile Fast Flowering outdoors in Northern Europe?
Yes — it's specifically bred for climates where autumn rain arrives early. Plants finish in September, before most mould-causing weather hits. Outdoor plants reach 130–160 cm and yield 450–500 grams each.
How does Speedy Chile compare to autoflowering strains?
You get similar speed (8 weeks total) but with photoperiod-level THC (16%) and higher yields (475–525 g/m² vs. typical auto yields of 300–400 g/m²). The only extra requirement is managing your light cycle with a timer.
What's the best training method for Speedy Chile?
Light LST or a single top during early veg works well. The plant stays under 100 cm indoors regardless, so heavy training isn't necessary. If running multiple plants per m², skip topping entirely and let them grow naturally in a SOG setup.
Does Speedy Chile have strong odour during flowering?
Moderate. The earthy, spicy terpene profile is noticeable but not overwhelming compared to strains like Skunk or Cheese. A carbon filter will handle it easily in an indoor setup — but don't skip the filter entirely.
