Auto Slurricane Cannabis Seeds by Advanced Seeds
Auto Slurricane is an autoflowering cannabis seed strain that combines the heavy indica genetics of Slurricane with ruderalis speed — giving you dense, trichome-coated buds in just 65–70 days from germination. Bred by Advanced Seeds from Do-Si-Dos and Purple Punch parentage, this auto delivers 26% THC and yields up to 500g/m² indoors without demanding much from the grower. It's one of Advanced Seeds' best sellers for good reason.
Pack Size
Auto Slurricane seeds come in packs of 3. Each seed carries the full Do-Si-Dos x Purple Punch autoflowering genetics. Advanced Seeds reports a high germination rate across the line, so you can expect strong, uniform seedlings from the pack.
Why Auto Slurricane Seeds Deserve a Spot in Your Grow
The original Slurricane photoperiod strain built a massive following in the US — that sweet, berry-forward indica profile from Purple Punch crossed with the complex cookie dough earthiness of Do-Si-Dos. The problem? Photoperiod Slurricane needs light schedule management, longer veg times, and a grower who knows when to flip. Not everyone wants that level of involvement, especially in a small tent or on a balcony.
Auto Slurricane strips away the complexity. You plant the seed, give it light and water, and 65–70 days later you're trimming sticky, purple-tinged colas. No light schedule changes, no sexing, no waiting around for months. The complete life cycle fits comfortably inside a single season outdoors — and if you time it right, you can run two or even three cycles between spring and autumn. Indoors, it barely matters what time of year it is.
The one honest limitation: autos generally produce slightly less per plant than their photoperiod counterparts. But Auto Slurricane partially compensates with its density. The buds pack tight, coated in a thick layer of milky trichomes that make them look almost white under grow lights. For the speed and ease you get, the trade-off is well worth it. We'd pick this over fussing with a photoperiod in a 60x60 tent any day.

Aroma and Resin: What Auto Slurricane Actually Smells Like
Crack open a cured jar of Auto Slurricane and the first thing that hits you is sweetness — not candy-sweet, more like crushed mixed berries left in a bowl overnight. There's a citrus edge underneath, almost like lemon zest, and as the buds break apart you catch a subtle earthy base that grounds the whole profile. It's the Purple Punch genetics doing the heavy lifting on the nose, with Do-Si-Dos adding that slightly doughy, biscuit-like complexity in the background.
The resin production is genuinely impressive for an autoflower. By late flower, the calyxes and sugar leaves are blanketed in milky-white trichomes. If you've ever grown a Purple Punch cross, you'll recognise the look — frosty, dense, and slightly purple at the tips when night temperatures drop below 18°C. For hash makers or anyone interested in dry sift, this strain gives you plenty to work with.
How to Grow Auto Slurricane Seeds
- Germinate your seeds. Use the paper towel method or soak directly in a glass of room-temperature water for 12–24 hours, then transfer to damp paper towels until the taproot appears (usually 24–72 hours).
- Plant into final containers. Autos don't like transplanting — their short life cycle doesn't give them time to recover from root shock. Plant the germinated seed directly into its final pot. An 11–15 litre fabric pot works well for indoor grows. Use a light, airy soil mix or coco-perlite blend.
- Provide 18–20 hours of light daily. Auto Slurricane doesn't need a light schedule change to flower — it does that on its own around days 18–25. An 18/6 or 20/4 light cycle from seed to harvest keeps energy costs reasonable while maximising photosynthesis.
- Keep feeding light during veg. For the first 2–3 weeks, the plant is small and doesn't need much. Start nutrients at quarter strength and increase gradually. Switch to bloom nutrients once you see the first pistils forming.
- Watch your height. Indoors, expect plants to stay under 90 cm. Outdoors in full sun, they can stretch to 140 cm. Low-stress training (LST) in the first few weeks of growth can help open up the canopy and boost light penetration to lower bud sites.
- Monitor humidity in late flower. Those dense, resinous buds are beautiful but they're also mould magnets if humidity climbs above 50% during the final two weeks. Keep airflow moving and consider a dehumidifier in humid climates.
- Harvest around day 65–70. Check trichomes with a jeweller's loupe — mostly milky with a few amber heads is the sweet spot for a heavy, body-focused effect. Dry in a dark room at 18–20°C and 55–60% humidity for 7–10 days, then cure in glass jars for at least two weeks.
Auto Slurricane vs Other Indica Autoflowers
| Strain | Seed Bank | THC | Cycle | Indoor Yield | Standout Trait |
|---|---|---|---|---|---|
| Auto Slurricane | Advanced Seeds | 26% | 65–70 days | Up to 500g/m² | Berry aroma, extreme resin |
| Northern Lights Auto | Various | 14–18% | 70–80 days | Up to 450g/m² | Classic indica, very forgiving |
| Gorilla Glue Auto | Various | 20–24% | 70–75 days | Up to 500g/m² | Sticky resin, diesel aroma |
Northern Lights Auto is the safer bet if you've never grown before — it tolerates mistakes better and finishes reliably. But it can't touch Auto Slurricane's THC levels or terpene complexity. Gorilla Glue Auto gets closer on potency, but the flavour profiles are completely different — diesel and pine versus berries and citrus. If you want that modern American dessert-strain flavour in an autoflower package, Auto Slurricane is the one to grow.
Complete your setup: If you're growing Auto Slurricane indoors, pair it with a complete grow tent kit — tent, light, ventilation, and carbon filter sorted in one go. A carbon filter is non-negotiable with this strain; the berry-sweet terpene profile is gorgeous but your neighbours don't need to enjoy it too. For outdoor growers, a fabric pot and quality organic soil mix will let this auto reach its full potential without overcomplicating things.
What Makes Auto Slurricane a Strong Pick
We've seen plenty of "auto versions" of popular photoperiod strains that lose the plot somewhere in the breeding — weaker terps, airy buds, half the potency. Advanced Seeds have done a proper job here. At 26% THC, Auto Slurricane sits at the top end of what autoflowers can deliver. The dense flower structure and heavy trichome coverage suggest the genetics translated well into the auto format.
The 65–70 day cycle is genuinely fast. Most indica autos take 70–85 days, so you're saving a week or two without sacrificing yield. That matters if you're running a small tent and want to fit in an extra cycle per year. Three harvests instead of two adds up quickly.
The main thing to watch for: those dense buds need good airflow. We've seen growers lose beautiful colas to bud rot in the final week because they got lazy with ventilation. Keep a fan oscillating, keep humidity in check, and you'll be fine. It's not a flaw in the genetics — it's just the reality of growing any dense indica in a closed environment.
Frequently Asked Questions
How long does Auto Slurricane take from seed to harvest?
The complete life cycle runs 65–70 days from germination to harvest. That's faster than most indica autoflowers, which typically need 70–85 days. You can realistically fit three cycles into a single year indoors.
How tall does Auto Slurricane grow indoors?
Expect heights of up to 90 cm indoors. Outdoors in a sunny spot, plants can stretch to around 140 cm. Low-stress training in the first few weeks helps keep height manageable and improves light distribution.
What yield can I expect from Auto Slurricane?
Under good indoor conditions, Auto Slurricane can produce up to 500g/m². Actual results depend on your light, nutrients, and growing medium. Even less experienced growers should get respectable harvests thanks to the strain's forgiving nature.
Does Auto Slurricane need a light schedule change to flower?
No. As an autoflowering strain, Auto Slurricane transitions to flower on its own regardless of light schedule. Most growers run 18/6 or 20/4 from seed to harvest for the best balance of growth and energy efficiency.
Is Auto Slurricane suitable for beginner growers?
Yes — it's one of the more forgiving autos we carry. The short cycle, compact size, and high germination rate make it straightforward. Just keep humidity below 50% in late flower to protect those dense buds from mould.
What does Auto Slurricane smell and taste like?
Sweet berries dominate, with a citrus edge and subtle earthy undertones. The Purple Punch genetics drive the fruit-forward profile, while Do-Si-Dos adds a slightly doughy, biscuit-like complexity. The aroma is strong — a carbon filter is recommended indoors.
Can I grow Auto Slurricane outdoors?
Absolutely. The fast 65–70 day cycle means you can harvest multiple times in a single outdoor season. Plants reach up to 140 cm in sunny spots. Start seeds after the last frost and you could fit two full runs before autumn.
