Passion #1 by Dutch Passion is one of those outdoor names that has quietly filled jars for decades. Its roots go back to California in the 1970s, and the line has been worked in the Netherlands since 1980, where it was once known as Amstel Gold. The feminized version gives you a giant, weather-tough outdoor plant with very high THC and a September finish, without the guesswork of sorting males.
What makes Passion #1 stand out is the mix of speed and size. She grows like a Sativa, racing upward through the summer, yet she flowers on an Indica-style clock of about 7 to 9 weeks. At Dutch latitudes most plants are ripe in early September, with a few slower phenotypes running into early October. For US growers dealing with early fall rain or cold snaps, that timing is a big deal.
Outdoors, plants routinely reach 200-350 cm (79-138 in), and with an early indoor start they can push past 400 cm (157 in). Dutch Passion puts the average dry harvest at 250-750 g per plant (8.8-26.5 oz per plant), and under ideal sun and soil a single plant can top 1.5 kg (52.9 oz) of dried flowers.
Thin leaves and an airy bud structure let wind move through the canopy, which helps keep bud rot and mold from getting a foothold during wet spells. She was bred for backyards, greenhouses and remote guerrilla spots, not for indoor tents under strong lamps.
Aroma, Flavor, and a Potent Up-High
Rub a flower and you get a fresh, tart scent of lemon and lime layered over woody herbs like rosemary and thyme, with a gentle spicy edge. The smell is clear but not overpowering, which many outdoor growers appreciate when neighbors are close by.
The smoke follows the nose: sour citrus up front, a pinch of spice and earth behind it. It burns smoothly, though the sharper notes can give a light tickle in the throat. Even the small sugar leaves end up coated in resin by the end of bloom, so trim is worth saving.
Dutch Passion has measured THC close to 20% in Passion #1, which puts her among the strongest classic outdoor strains in their catalog. The effect opens with an energetic, social head high. Keep going and a mellow body stone settles in, relaxed but rarely sleepy. It is a long-lasting hybrid buzz that works for afternoons with friends as well as for quiet evenings.
Growing Passion #1 Feminized Seeds Outdoors
This is an easy plant that does not need special nutrients or a strict feeding plan. Good, preferably organic, soil plus plenty of direct sun is enough to produce long, continuous colas. Her buds can reach 40-50 cm (15.7-19.7 in) in length and get heavy enough to sag, so plan on stakes or a trellis late in the season.
Passion #1 has a strong urge to grow straight up. Topping or fimming several times spreads her out and keeps height under control, and an outdoor SCROG net is another way to flatten the canopy. To grow the largest plants, germinate indoors in spring and veg for 4-6 weeks before moving outside. If you have 8-10 weeks, repot a few times as she grows, and harden plants off over 1-2 weeks before planting out.
Big containers pay off: Dutch Passion suggests at least 50-100 L (13-26 gal), and fabric pots of several hundred liters for maximum results. In the open ground with full sun, this strain shows what it can really do.

FAQ
Is Passion #1 an indoor or outdoor strain?
Passion #1 was bred for outdoor and greenhouse growing. Dutch Passion does not recommend growing her indoors under powerful lights, as she is built to use natural sun, open soil and a long summer.
When is Passion #1 ready to harvest?
Flowering takes about 7-9 weeks. In the Northern Hemisphere most plants finish in early September, while some slower phenotypes need until the end of September or early October.
How strong is Passion #1?
Dutch Passion rates her THC as very high and has measured levels of nearly 20%. The high starts energetic and sociable and turns into a relaxed, pleasant body stone with larger amounts.
How tall does Passion #1 get?
Outdoor plants average 200-350 cm (79-138 in). With an early indoor start and great conditions, they can exceed 400 cm (157 in). Topping, fimming or a SCROG net helps keep her height manageable.
What yield can I expect from Passion #1 feminized seeds?
Average dry yields run from 250 to 750 g per plant (8.8-26.5 oz per plant). In optimal conditions, with big roots and full sun, a single plant can produce more than 1.5 kg (52.9 oz).
Does Passion #1 handle wet weather?
Yes. Her thin leaves and open bud structure give mold and bud rot less of a hold, and she copes with rain and cold better than many traditional strains, which makes her a good fit for temperate climates.
