Think Big Auto starts with Dutch Passion’s well-known Auto Think Different, a strain built on stable, potent AK420 genetics. From several hundred plants, the breeders singled out a handful of exceptional XXL performers and used them to found a new line. Careful selective breeding then shaped those plants into a compact, commercially minded autoflower with huge yield potential.
What sets her apart is the ratio of size to harvest. Most plants stay between 50-75 cm (20-30 in) and almost never exceed 1 m (39 in), yet they are packed with flowers from head to toe. Short internodes allow the buds to merge into continuous colas, some as thick as a leg, which makes her a strong candidate for multi-layer racks and grow rooms with limited height.
A yield of 500-600 g/m² (1.64-1.97 oz/ft²) is realistic for growers with moderate experience. Experts with the right lighting and method can reach 600-750 g/m² (1.97-2.46 oz/ft²), and top growers occasionally exceed 800 g/m² (2.62 oz/ft²). Dutch Passion notes 1-2 g per watt as achievable.
The price for that weight is a little patience. Plan on 11-13 weeks from seed, a bit longer than the average auto, because those extra weeks are when the colas fill out and harden.
Citrus Terpenes and an Uplifting Effect
The aroma shares some DNA with Auto Think Different but usually has its own character. Expect a fruity, citrus-forward bouquet with sweet and floral notes, sometimes rounded off by creamy or piney undertones.
The flavor is where she really shines. Inhale and exhale both carry a bright citrus tang, like the fresh zest of a ripe lemon, along with hints of lime and frankincense. Whether rolled or vaped, the fruity sweetness is immediate.
Dense trichome coverage gives the buds real strength. The high is a powerful, uplifting sativa-style effect: energetic, sociable and creative, the kind of buzz that gets you started on projects, music or a favorite game. There is no couch-lock, though larger doses bring on a deeper relaxation.
That profile makes her well suited to daytime and early evening use, especially as a way to switch off after the workday without feeling sedated.
Growing Think Big Auto
Early growth can look slow, but she keeps building steadily without much stretch, branching outward on thick, sturdy stems. She is easy to manage and does well grown naturally, but the heaviest harvests come from a SOG, ideally in hydro under powerful LEDs.
She loves light, so intensity drives yield. Hang lamps higher or dim them during the first month to let seedlings adjust, then ramp up gradually. Dutch Passion recommends a 20/4 schedule; 24/0 is possible, but it can cause light stress and nutrient issues that experienced growers handle more easily than beginners.
Outdoors, allow one to two extra weeks to finish because of cooler nights. Avoid regions with very short, cold summers or very humid tropical heat, as the fat colas dislike moisture. Support the heaviest branches late in bloom and let the plants fully mature for the biggest harvest.

FAQ
Where does Think Big Auto come from?
Dutch Passion selected a few exceptional XXL plants from several hundred Auto Think Different seedlings and used them as the foundation for Think Big Auto. She keeps the AK420-based stability and potency of her parent.
How tall does Think Big Auto get?
Most plants finish at 50-75 cm (20-30 in) and almost always stay below 100 cm (39 in), which suits low grow rooms and multi-layer setups.
What yield can I expect from Think Big Auto?
Growers with some experience can expect 500-600 g/m² (1.64-1.97 oz/ft²). Experts can reach 600-750 g/m² (1.97-2.46 oz/ft²), and rare cases exceed 800 g/m² (2.62 oz/ft²).
Why does Think Big Auto take 11-13 weeks?
Her colas keep swelling and hardening during the last weeks. Harvesting early costs yield, so Dutch Passion recommends giving her the full 11-13 weeks from seed.
What light schedule works best?
Dutch Passion recommends 20/4. A 24/0 schedule is possible, but it can cause light stress and nutrient issues, so it is better left to experienced growers.
What does Think Big Auto taste like?
Mostly citrus: bright lemon zest on the inhale and exhale, with lime, sweet fruit, floral notes and a hint of frankincense.
