Speedy Boom Auto Cannabis Seeds by Kannabia
Speedy Boom Auto is a fast-finishing autoflowering cannabis seed from Kannabia that goes from germination to harvest in roughly 60–65 days. Built around a blend of indica and sativa genetics crossed with ruderalis for automatic flowering, this strain keeps things simple: compact plants, solid yields, and an uplifting effect profile that leans more cerebral than couch-lock. If you want quick results without babysitting a photoperiod schedule, this is where you start.
Why Speedy Boom Auto Seeds Stand Out
Speed is the headline here — and it's not marketing fluff. Where most autoflowers ask for 70–80 days, Speedy Boom Auto wraps up its full life cycle in around 60–65 days from germination. That's a proper advantage if you're running multiple cycles per year or growing outdoors in a climate with a short summer window. We've seen growers in northern Europe pull two full outdoor runs in a single season with this strain.
The genetics trace back to Kannabia's breeding programme, which crossed a fast indica-dominant auto with a sativa-leaning parent to balance the effect. The ruderalis backbone means the plant flips to flower on its own — no light schedule adjustments, no timers, no stress. You give it light, water, and nutrients, and it does the rest. Kannabia also sometimes lists this one under the name "Speedy Gonzales," so if you've seen that floating around, it's the same genetics.
One honest note: because the life cycle is so compressed, there's less room to recover from mistakes. Overwater in week two or burn the roots with too-hot nutrients, and you'll feel it in the final yield more than you would with a photoperiod strain that has months to bounce back. That's not a flaw — it's just how fast autos work. Respect the timeline and you'll be fine.
Speedy Boom Auto Grow Characteristics
Speedy Boom Auto stays compact, typically finishing between 50–90 cm indoors depending on pot size and light intensity. Outdoors with direct sun and a decent-sized container, you might see plants push towards 100 cm, but this isn't a strain that takes over your garden. The short stature makes it a strong pick for grow tents, balconies, or any space where vertical room is limited.

The branching structure is fairly open, which means decent airflow through the canopy without heavy defoliation. In a small tent — say 60x60 or 80x80 — you can comfortably fit 4 of these in 7–11 litre pots. Under 18–20 hours of light indoors, expect dense, resinous buds forming along the main cola and side branches by week 4–5.
Aroma, Flavour, and Effect Profile
Speedy Boom Auto develops a sweet, slightly earthy aroma during flowering with hints of citrus that sharpen as the buds mature. Crack a dried bud open and you'll notice that citrus note more clearly — not overpowering, but present. The taste follows the nose: smooth, mildly sweet, with a clean finish that doesn't coat your mouth in resin the way heavier indica strains do.
The effect leans uplifting and cerebral. Users and growers consistently describe a clear-headed, energetic quality rather than heavy sedation. The moderate THC level means you're not getting flattened — it's more of a functional, daytime-friendly effect. Creative tasks, social settings, and gentle outdoor activities suit this strain well. The indica side shows up as a light physical relaxation that rounds off the edges without dragging you down.
Compared to something like a heavy Kush auto, Speedy Boom Auto is noticeably lighter on the body. If you're after a strain that lets you stay productive, this one delivers. If you want full-body sedation, look at an indica-dominant auto like Auto Ghost OG or Auto Blue Pyramid from Kannabia's range instead.
How to Grow Speedy Boom Auto Seeds
- Germinate your Speedy Boom Auto seeds using the paper towel method or directly in a small pot of moist, light soil mix. Taproots typically emerge within 24–72 hours.
- Transplant seedlings into their final container early — ideally within the first week. Autos don't love root disturbance mid-cycle, so going straight into an 11-litre pot avoids transplant shock entirely.
- Set your indoor light schedule to 18 hours on, 6 hours off. Some growers run 20/4 for autos; either works, but 18/6 gives the plant a rest period without sacrificing much growth.
- Keep nutrients light during the first 2–3 weeks. Seedlings don't need heavy feeding, and with a 60–65 day life cycle, there's no time to flush out a nutrient burn. Start at half the manufacturer's recommended dose and increase gradually.
- Switch to bloom nutrients when you see the first pre-flowers forming, usually around day 20–25. The transition is automatic — you'll notice white pistils appearing at the nodes.
- Monitor humidity closely during weeks 5–8. Dense buds in a compact canopy can invite mould if relative humidity sits above 55%. A small extraction fan and carbon filter handle both airflow and odour.
- Harvest when roughly 70–80% of trichomes have turned milky white under a jeweller's loupe. With Speedy Boom Auto, this typically lands around day 60–65 from germination. Amber trichomes indicate a more sedative effect — harvest earlier for the uplifting character this strain is known for.
Complete your setup with a propagation kit for reliable germination, and pair these seeds with a compact grow tent if you're running indoors. A jeweller's loupe is worth grabbing too — checking trichome colour is the only reliable way to nail your harvest window with a fast auto like this one.
Frequently Asked Questions
How long does Speedy Boom Auto take from seed to harvest?
Around 60–65 days from germination to harvest. That's the full life cycle — no separate veg and bloom phases to manage. It's one of the fastest autoflowers in Kannabia's catalogue.
Is Speedy Boom Auto good for beginners?
Yes. The autoflowering genetics remove the need to manage light schedules, and the compact size means it fits easily in small spaces. The short cycle also means less time for problems to compound. Just go easy on nutrients early on.
How strong is Speedy Boom Auto?
THC levels are moderate. You get a clear-headed, uplifting effect rather than heavy sedation. It's a functional strain — good for daytime use rather than knocking you out on the sofa.
Can I grow Speedy Boom Auto outdoors?
Absolutely. The compact size and fast cycle make it well suited to balconies, gardens, and guerrilla grows. In northern Europe, you can even fit two full outdoor runs into a single summer season thanks to the 60–65 day turnaround.
How tall does Speedy Boom Auto get?
Expect 50–90 cm indoors. Outdoors in a large container with direct sun, it may stretch towards 100 cm. Either way, it stays manageable — no need for aggressive training or topping.
What does Speedy Boom Auto smell like?
Sweet and earthy with a citrus edge that becomes more pronounced as the buds dry and cure. It's noticeable but not overwhelming — a carbon filter handles it easily in a tent setup.
Do I need to change the light schedule for autoflowers?
No. Autoflowering strains like Speedy Boom Auto flower based on age, not light cycle. Set your lights to 18/6 or 20/4 from day one and leave them there for the entire grow.
What's the yield like on Speedy Boom Auto?
Yields are moderate — this strain prioritises speed over sheer production. In a well-managed indoor setup, expect solid but not record-breaking harvests. For maximum grams per plant, a longer-cycle autoflower would be a better pick.
