Smoothie Auto Cannabis Seeds by FastBuds

Smoothie Auto is a feminised autoflowering cannabis seed from FastBuds that crosses Blueberry with Somango to produce some of the fruitiest bud you'll ever grow. She stays compact at 80–110cm, finishes in 8–9 weeks from seed, and delivers XL harvests relative to her size. If you chase flavour above all else, this is the seed to plant.

Why Smoothie Auto Seeds Deserve a Spot in Your Grow

FastBuds bred Smoothie Auto by pairing two strains that have been fan favourites for decades: Blueberry and Somango. The result is a genetic profile loaded with berry and tropical fruit terpenes — think ripe mango layered over creamy berry sorbet. The smoke itself is remarkably smooth for how flavourful it is, which is where the name comes from.

But flavour alone doesn't make a great seed. What makes Smoothie Auto genuinely useful is her size. With a typical indica structure — bushy, thick main cola, minimal side branching — she tops out between 80 and 110cm. That's short enough for a balcony grow, a small tent, or a guerrilla patch where discretion matters. We've seen growers fit four of these into a 60x60 tent using SOG, and the canopy fills out beautifully.

The autoflowering genetics mean no light schedule changes, no sexing headaches, and a full cycle done in roughly 8–9 weeks from germination. For the impatient among us (and honestly, that's most of us), that timeline is hard to beat. She also responds well to low stress training — bend and tie the main stem during early veg, and you'll expose more bud sites to light without stressing the plant.

Smoothie Auto Flavour and Effects

The terpene profile on Smoothie Auto is where she really earns her keep. Open the jar after curing and you get an immediate hit of ripe tropical mango with a sweet, creamy berry undertone — closer to a fruit sorbet than a raw berry. When smoked or vaped, those notes come through clean and full. There's none of that harsh, dry-throat finish you get from less refined genetics. The exhale is genuinely smooth.

The effect is balanced. You get a clear-headed, slightly uplifting onset that settles into a relaxed body state without locking you to the sofa. It's the kind of smoke that works mid-afternoon when you still want to be functional but fancy taking the edge off. THC sits in the 19–23% range, so she's got enough potency to satisfy experienced smokers while not bulldozing newcomers who pace themselves.

One honest note: if you're after a heavy-hitting, knock-you-sideways indica, Smoothie Auto isn't that. Her strength is balance and flavour, not raw sedation. For a heavier punch from FastBuds, look at Gorilla Cookies Auto instead.

Growing Smoothie Auto Seeds — What to Expect

Smoothie Auto is one of the more forgiving autoflowers we carry. She doesn't demand heavy feeding, tolerates minor environmental fluctuations, and her compact structure means less defoliation work than stretchier sativas. Here's how to get the best from her:

1. Germinate your Smoothie Auto seed using the paper towel method or directly in a small pot of moist, airy substrate. Taproots typically emerge within 24–72 hours.
2. Transplant into her final container early — autos don't love root disturbance. A 7–11 litre pot is the sweet spot for balancing root space with her compact growth habit.
3. Provide 18–20 hours of light per day throughout the full cycle. Autoflowers don't need a 12/12 flip, and more light hours mean more photosynthesis and denser buds.
4. Begin low stress training around week 2–3 by gently bending the main stem to open up the canopy. Secure with soft plant ties. This encourages more even light distribution across bud sites.
5. Feed lightly during veg, then increase phosphorus and potassium once you see the first pistils forming — usually around week 3–4 from seed.
6. Monitor humidity closely during late flower. Those thick, dense colas can trap moisture and invite mould if relative humidity stays above 50% in the final two weeks.
7. Harvest when trichomes show a mix of milky white and 10–20% amber under a jeweller's loupe. Expect this around week 8–9 from seed, though some phenotypes may take a few days longer.
8. Dry slowly 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 mango and berry terpenes intensify significantly with a proper cure.

Smoothie Auto Compared to Similar FastBuds Strains

Choosing between autoflowers can be tricky when several tick similar boxes. Here's how Smoothie Auto stacks up against two other popular FastBuds options we carry:

If flavour is your top priority and you're working with limited space, Smoothie Auto is the pick. If you want something that looks as good as it tastes (those purple buds are stunning), go Purple Lemonade Auto. And if you just want the hardest-hitting smoke FastBuds makes, Gorilla Cookies Auto is the one — though she can stretch taller and needs more headroom.
