Passion #1 Regular from Dutch Passion is the original, non-feminized form of a strain that has been part of Dutch outdoor growing for more than four decades. The line started in California in the 1970s, came to the Netherlands around 1980 and was long sold as Amstel Gold. These regular seeds give you both male and female plants from a time-tested outdoor gene pool, the way growers worked with it long before feminized seeds existed.
Each pack holds 10 regular photoperiod seeds, and you can expect roughly half to be female and half male. That is exactly what breeders, seed makers and hunters of keeper mothers are after. Males let you collect pollen and build your own crosses, while the females give you a range of phenotypes to compare side by side.
The traits that made Passion #1 famous are all there to select from: quick flowering of about 7-9 weeks, explosive vertical growth to 200-350 cm (79-138 in), very high THC near 20%, and a tough, open structure that shrugs off rain better than most. Outdoor females can produce 250-750 g per plant (8.8-26.5 oz per plant), with exceptional plants reaching more than 1.5 kg (52.9 oz).
Why Breeders Pick Passion #1 Regular Seeds
Decades of selection for speed, size, yield and potency make Passion #1 a strong outdoor building block. Crossing a Passion #1 male into a later-finishing strain is a classic way to pull harvest dates forward and add weather resistance, because her open, airy flowers and thin leaves give mold less room to develop.
For phenotype hunting, run a full pack and watch closely. Some plants show more of their Indica side during veg, then switch to a taller, slimmer Sativa shape once flowering kicks in, around late July or early August at Dutch latitudes. Note which females finish first in early September and which carry the heaviest, most resinous colas into early October.
Keep your favorite female as a mother plant indoors on a long day schedule and take cuttings each spring. Many outdoor growers like this approach because a selected clone gives a uniform garden year after year, while regular seeds keep the genetic diversity alive for future projects.
Aroma, High, and Outdoor Growing Notes
Expect a tart, fresh nose of lemon and lime mixed with rosemary, thyme and light spice. The smell is noticeable but not extreme, and the smoke is smooth with sour citrus and a bit of earth. The high is energetic and talkative at first, with a gentle body relaxation that builds the more you smoke.
Grow her outdoors or in a greenhouse; she was not bred for indoor lamps. Start seeds indoors 4-6 weeks before planting out, harden them off for 1-2 weeks, and give each plant a large container of at least 50-100 L (13-26 gal) or open ground. Identify and separate males early if you are not planning to collect pollen, and top or fim the females several times to tame their height. Her colas can stretch 40-50 cm (15.7-19.7 in) and get heavy, so add support late in bloom.

FAQ
What is the difference between Passion #1 Regular and feminized seeds?
Regular seeds produce both males and females, roughly 50/50, while feminized seeds are bred to give female plants. Choose the regular version if you want males for pollen, plan to make crosses, or want to select mother plants from the original genetics.
How many Passion #1 Regular seeds come in a pack?
Passion #1 Regular comes in packs of 10 regular photoperiod seeds, which gives you enough plants to compare phenotypes and keep at least one male and several females.
Is Passion #1 a good parent for breeding outdoor strains?
Many breeders value it for that role. Decades of selection for speed, size, yield and potency, plus a fast 7-9 week bloom and good weather resistance, make it a useful partner for crosses aimed at outdoor and greenhouse growing.
How do I spot male plants?
Males show small pollen sacs at the nodes shortly after flowering begins, while females show white pistils. Separate males early unless you want to collect their pollen, so they do not seed your whole crop.
When does Passion #1 Regular finish outdoors?
In the Northern Hemisphere most females are ready in early September, while some phenotypes need until late September or early October. Flowering itself takes about 7-9 weeks.
Can I keep a Passion #1 mother plant?
Yes. Select your favorite female, keep a cutting under a long vegetative light schedule indoors, and take clones each spring. You get a uniform outdoor crop based on the plant you liked most.
