Dutch Passion Blueberry Feminised Cannabis Seeds
Dutch Passion Blueberry is a feminised cannabis seed strain built on Afghani Indica genetics with Thai and Mexican Sativa influences — a combination that won first place at the High Times Cannabis Cup in 2000. These seeds produce compact, fruity plants that became a coffeeshop staple across Amsterdam almost overnight. If you've spent any time behind a counter in this city, you've heard someone ask for Blueberry by name.
Pack Sizes
| Pack | Seeds | SKU |
|---|---|---|
| Standard | 3 feminised seeds | CSDP0008 |
| Value | 5 feminised seeds | CSDP0120 |
Go for the 5-pack. Blueberry can be a temperamental feeder, and having a couple of extra plants means you can dial in your nutrients on one before committing to the rest. We'd always rather have a spare than wish we did.
Why Dutch Passion Blueberry Seeds Deserve a Spot in Your Collection
Some strains win awards and then fade. Blueberry hasn't. Dutch Passion released it, it took first prize at the 2000 High Times Cannabis Cup, grabbed third place again in 2001, and then quietly became one of the most requested varieties in Amsterdam's coffeeshops for the next two decades. That kind of staying power doesn't come from marketing — it comes from what's in the jar.
The genetics tell the story: a mostly Afghani Indica backbone gives Blueberry its dense structure and resinous buds, while traces of Thai Sativa and Mexican Sativa add complexity to the flavour and effect profile. At 19.5% THC, it hits hard enough to satisfy experienced growers and their friends, but the effect leans more towards a warm, relaxed state than anything that pins you to the sofa. We've had customers describe the smell as genuinely like walking past a punnet of fresh blueberries — not a vague "fruity note," but actual berries. Crack a cured bud open and you'll get it immediately.
The honest limitation? Yield is modest. You're not going to fill a drying rack from two plants. Blueberry trades quantity for quality, and every grower who's run it knows the deal. The buds are dense, sticky, and absolutely caked in trichomes — you just don't get mountains of them. If you're chasing weight, look at something like Dutch Passion's Think Big or a heavy-yielding hybrid. If you're chasing flavour and bag appeal that makes people stop mid-conversation, this is the one.
Growing Dutch Passion Blueberry — What to Expect
Blueberry finishes flowering in approximately 7 weeks, which is quick for a strain this flavourful. She's compact and bushy — classic Indica growth pattern — so she works well in smaller tents and SOG setups. The leaves often develop beautiful purple and blue hues towards the end of flowering, especially if nighttime temperatures drop below 15°C. It's genuinely one of the prettiest plants you'll grow.
Here's where the honesty comes in: this plant is fussy with nutrients. She doesn't like being overfed, and she'll tell you about it with burnt leaf tips and lockout before you've even noticed the problem. If you're used to strains that shrug off a heavy hand, Blueberry will humble you. Read her signals — slight yellowing at the tips means back off, not add more. Less is more with this one.
- Germinate your Blueberry seeds using the paper towel method or directly in a small pot of lightly moistened seedling soil. Taproots typically emerge within 24–72 hours.
- Transplant seedlings into their final containers once the first true leaves appear. A 7–11 litre pot works well for indoor grows — she doesn't need massive root space given her compact stature.
- Keep nutrient strength at around 50–60% of the manufacturer's recommendation during vegetative growth. Blueberry is sensitive to overfeeding, particularly with nitrogen. Watch the leaf tips.
- Switch to a 12/12 light cycle to trigger flowering. Expect dense bud formation to begin within the first two weeks, with full maturity at around 7 weeks.
- Drop nighttime temperatures to 10–15°C during the final two weeks if you want those signature blue and purple colours. This is cosmetic, not required — but it's half the reason people grow this strain.
- Harvest when trichomes are mostly milky with a few turning amber. Dry slowly in a dark room at 18–20°C with 50–55% humidity for 7–10 days, then cure in glass jars for at least two weeks. The blueberry flavour deepens significantly during curing.

Running Blueberry indoors? Pair her with a complete grow tent kit — the compact Indica structure fits nicely in an 80x80 setup. A pH meter is borderline mandatory for this strain given her nutrient sensitivity. And if you want to compare genetics, Dutch Passion's Orange Bud offers a similar old-school pedigree with a more forgiving feeding schedule.
Blueberry vs Other Indica-Dominant Strains
| Strain | Genetics | THC | Flowering | Yield | Difficulty |
|---|---|---|---|---|---|
| Blueberry (Dutch Passion) | Afghani / Thai / Mexican | 19.5% | ~7 weeks | Modest | Intermediate |
| Northern Lights | Afghani Indica | ~18% | 7–8 weeks | Medium-High | Easy |
| Orange Bud (Dutch Passion) | Skunk hybrid | ~16% | 7–8 weeks | Medium | Easy |
If you want a forgiving first grow, Northern Lights is still the go-to recommendation. But if you've already got a couple of runs under your belt and you want something with genuine character — a strain that makes people ask "what is that?" when you open the jar — Blueberry is the answer. The lower yield is a trade-off, not a flaw.
Frequently Asked Questions
Is Dutch Passion Blueberry suitable for beginner growers?
Not really. Blueberry is nutrient-sensitive and requires the grower to spot early signs of overfeeding or lockout. If it's your first grow, start with something more forgiving like Northern Lights or an autoflower, then come back to Blueberry once you're comfortable reading your plants.
How much do Dutch Passion Blueberry seeds yield?
Yield is modest compared to modern hybrids. You're growing Blueberry for flavour, bag appeal, and resin production — not to fill a warehouse. Expect dense, compact buds rather than massive colas. SOG setups can help maximise output per square metre.
Why does Blueberry turn purple and blue?
The colour change comes from anthocyanin pigments in the genetics, triggered by cooler nighttime temperatures (10–15°C) during late flowering. It's not a sign of stress — it's a natural expression of the Afghani and highland genetics. Not every phenotype will colour up equally.
What does Blueberry cannabis smell and taste like?
Fresh blueberries — genuinely. Not a vague fruitiness, but an unmistakable berry aroma that intensifies during curing. The taste follows through: sweet, fruity, with a slightly earthy Indica undertone on the exhale. The terpene profile needs at least two weeks of proper curing to fully develop.
What awards has Dutch Passion Blueberry won?
First place in the general category at the High Times Cannabis Cup in 2000, and third place at the same competition in 2001. It also became one of the best-selling strains in Amsterdam's coffeeshops during that era — a reputation it still holds.
How long does Blueberry take to flower?
Approximately 7 weeks from the start of the 12/12 light cycle. That's fast for a strain this flavourful. Check trichome colour with a jeweller's loupe rather than counting days — milky with some amber is the sweet spot for harvest.
Should I buy the 3-pack or 5-pack of Blueberry seeds?
The 5-pack. Blueberry's nutrient sensitivity means your first plant might not be your best. Having extra seeds lets you learn the strain's quirks without running out. Think of the extra two seeds as insurance.
