Californian Snow Auto Cannabis Seeds - Fast Buds
Type: Autoflowering, Sativa-dominant hybrid.
Flowering Time: 8–9 weeks
Best For: Outdoor growing in cold climates, short-season cultivation, and quick harvests
How does Californian Snow Auto taste?
Expect a crisp, sweet citrus flavour with icy undertones, a bit like a lemon sorbet with a hefty kick. The high is uplifting and energising, perfect for a clear-headed buzz during the day.
Why Californian Snow Auto is ideal for cold climates:
Californian Snow Auto was bred explicitly by Fast Buds to thrive in cooler conditions. Its Ruderalis backbone and speedy flowering time make it a top choice for growers dealing with unpredictable weather, short summers, or early frost. This strain won't need endless sun or scorching heat; it's a snow-hardened survivor that still produces dense, frosty buds under pressure.
ASC Grow Tip:
If you're growing cannabis outdoors in northern Europe or a mountain region, start this strain indoors in early spring. Move it outside once the last frost has passed, and keep an eye on moisture levels during late flowering. You'll get the best results when you harvest just before the autumn rains fall.
Gorilla Glue Auto Cannabis Seeds – Barney's Farm
Type: Autoflowering, Indica-dominant hybrid
Flowering Time: 70–75 days: seed to harvest
Best For: Cold climates, high-THC lovers, and anyone who wants heavy-hitting nugs without the fuss
How does Gorilla Glue Auto taste?
Earthy, piney, and sticky sweet. Like a chocolatey forest floor soaked in diesel. Expect full-throttle flavour and a high that clings to your brain and body like…erm... glue. It's knockout stuff and best saved for nighttime or medical use.
Why Gorilla Glue Auto is ideal for cold climates:
Barney's Farm built this beast to be tough. With sturdy Ruderalis genetics, fast flowering, and a dense, chunky structure, it handles cool temps and sudden showers without throwing a tantrum. It's not just frost-tolerant; it finishes strong when other strains still sulking about the lack of sun.
ASC Grow Tip:
This one likes room to stretch. You're golden if you've got a sheltered outdoor spot with full sun. Start indoors if your nights are still icy, and give the branches some airflow as flowers stack up and become compact, meaning mould can sneak in if you're not paying attention. Harvest around mid-October if you're north of the Alps.
Do-Si-Dos Automatic Cannabis Seeds – Royal Queen Seeds
Type: Autoflowering, Indica-dominant hybrid
Flowering Time: 8–9 weeks
Best For: Cold-climate growers who want flavour, power, and a bit of flash without waiting all season.
How does Do-Si-Dos Auto taste?
Sweet and earthy with a bit of citrus zip. It's like someone dunked a cookie in lemon sherbet. The effects of Do-Si-Dos? Relaxing, euphoric, and perfect for slowing the world down a notch or ten.
Why Do-Si-Dos Auto is ideal for cold climates:
It's all cut and thrust with Do-Si-Dos. With quick-flowering Ruderalis genetics and a naturally compact build, it keeps a low profile while getting the job done. Do-Si-Dos Auto is ideal if your summer feels more like an extended, wet weekday. It's unbothered by cold snaps, doesn't flinch at less-than-perfect sunlight, and finishes before autumn can ruin your grow run.
ASC Grow Tip:
Do-Si-Dos Auto is a squat and stealthy plant great for patios, balconies, or low-key grows in unpredictable weather. If you're in a colder region, give it a head start indoors, then move it outside as soon as things warm up. It's low maintenance, but don't forget to feed it!
Sugar Black Rose Auto Cannabis Seeds – Delicious Seeds
Type: Autoflowering, Indica-dominant hybrid
Flowering Time: 8–9 weeks
Best For: Cold, wet climates where you need short, stocky plants and seriously sticky results
How does Sugar Black Rose Auto taste?
Sweet, floral, and full-bodied. Yes, just because it's cold doesn't mean you can't have fruit. This autoflower tastes like dark berries wrapped in incense. This one's rich, smooth, and leans into the old-school terp world. The high is deeply relaxing, with giggles if you hit it just right.
Why Sugar Black Rose Auto is ideal for cold climates:
It's small, fast, and built like a tank that you'd want in a cold weather growing war. Sugar Black Rose Auto doesn't mind the elements and finishes quickly before the real cold kicks in. It's ideal for growers battling shorter summers or soggy September. The great thing about this auto is that the dense flowers come with natural mould resistance, which is a lifesaver when it's raining.
ASC Grow Tip:
Don't let the size of these plants fool you. Sugar Black Rose is an auto that loves the sun when she can get it. Give this auto a bright spot, and it will produce dense, resin-dripping flowers that'll stink the room in the best way. Perfect for terraces, discreet gardens, or anyone trying to keep things compact but potent.
Royal Critical Automatic Cannabis Seeds – Royal Queen Seeds
Type: Autoflowering, Indica-dominant hybrid
Flowering Time: 9–10 weeks
Best For: Cooler climates, hands-off growers, and anyone who wants significant results without playing babysitter in a grow tent.
How does Royal Critical Auto taste?
Spicy, woody, and just the right kind of old-school. Think dried herbs, pine needles, and a hint of musk. The high is smooth, body-heavy, and chill without turning your limbs to jelly. Great for winding down or disappearing into the sofa.
Why Royal Critical Auto is ideal for cold climates:
Royal Critical Auto doesn't need a VIP grow setup to thrive. It's compact, rugged, and finishes quickly, so it's not hanging around waiting to get ruined by late-season bad weather. It's been a cold-weather go-to across Europe for a reason: this strain gets in, gets out, and gets the job done.
ASC Grow Tip:
Start early indoors, then move Royal Critical Auto outside once the frost has packed up and left. Keep the airflow tidy as buds can get thick near harvest, and it will cruise to the finish line with minimal stress. This one's great if you're growing at altitude, near the coast, or anywhere the weather can't decide.
Sweet Purple Cannabis Seeds – Paradise Seeds
Type: Photoperiod, 50/50 Sativa-Indica hybrid
Flowering Time: 50–55 days
Best For: Outdoor growers in cool, wet climates, especially those looking for an old-school purple that thrives in rougher conditions
How does Sweet Purple taste?
It's got that clean, herbal edge you'd expect from a classic outdoor strain. Think mint, pepper, and a touch of berry on the back end. Smooth, earthy, and low-key sweet without tasting like a fruit basket. The high? Clear, relaxed, and balanced. Just enough heat to keep you functional, just enough body to make you forget about your to-do list.
Why Sweet Purple is ideal for cold climates:
This is one of the OG outdoor strains bred by Paradise Seeds in Holland, from when you had to grow hardy or go home. Sweet Purple was made for the northern grower, and it shows. It handles cool nights, damp air, and surprise showers like a pro. Mould resistance is baked into its DNA and still produces solid yields without the drama.
ASC Grow Tip:
Sweet Purple is a photoperiod, so make sure you're timing your grow right and start early to finish before the real cold hits. This one can stretch to 2 metres outdoors, so give it space and a bit of shelter from the wind. It's an excellent choice for guerrilla grows or gardens where the weather can turn quickly. No-frills, no fuss, just dependable flowers with a purple twist.
