Blackberry vs Blueberry cannabis strain comparison
Blackberry and Blueberry are two high quality strains with certain similarities. Both have a delicious terpene profile which tastes of sweet, dark fruit. Both are THC rich strains that pack a pleasant and powerful high.
Connoisseur growers adore the bag-appeal of these strains, the penetrating aroma of rich forest fruit and dark berries hints at the smoking pleasure which awaits. Flecks of blue and purple in the buds contrast beautifully with the bright orange hairs and the white trichome coating. They’re both highly desirable strains for any cannabis grower, but is it possible to say which is the best?
Blackberry vs Blueberry cannabis seed genetics
Despite a similarity in certain aspects of their appearance and aroma, the genetic backgrounds of Blackberry vs Blueberry cannabis strains do show significant differences. Blackberry is classically regarded as a sativa/indica hybrid strains with genetics from Black Domina and Raspberry Cough. Bloom time is around 10 weeks from the feminised seed version.
It’s worth adding that there are several different takes on the Blackberry genetic line including some high THC autoflower seeds in the form of Auto Blackberry Kush. These genetics came from Hash Plant x Blueberry and often produce plants with stunning, eye-catching blue/purple blooms alongside the signature sweet blackberry taste.
Blueberry is a legendary cannabis strain. The Dutch Passion original version dates back to the 1970’s. Blueberry seeds are indica dominant and have won several cannabis cups and produce medium, rather than large or XL, yields. This doesn’t worry the thousands of repeat Blueberry growers who tend to be quality focussed growers seeking top-shelf buds.
Blueberry delivers a deeply pleasurable and intense high alongside particularly soothing physical and mental effects which are equally popular with recreational and medical users. As a cornerstone variety, Dutch Passion have made Blueberry available in regular cannabis seeds, feminised seeds and autoflower seeds (as Auto Blueberry). Blueberry regular seeds have been used extensively by breeders around the world in the creation of new strains.
Blackberry vs Blueberry strain flowering time
The indica dominant Blueberry takes around 8 weeks in bloom when growing regular cannabis seeds or feminised seeds. Blackberry, with perhaps a little more sativa influence has a slightly longer bloom period, around 10 weeks. But both strains are relatively easy and straightforward to grow in bloom. Blueberry tends to show lower stretch levels than Blackberry and may suit those grow rooms with lower amounts of vertical space/headroom.

One unusual consideration with autoflowering strains containing these Blueberry/Blackberry cannabis genetics, such as Auto Blueberry and Auto Blackberry Kush, is the unusually rapid pace of the growth cycle. Both Auto Blueberry and Auto Blackberry Kush can be ready to harvest as little as 8-9 weeks after germinating the autoflower seeds!
This makes them amongst the fastest growing cannabis seeds available. Blueberry, Auto Blueberry and Auto Blackberry Kush are all part of the multiple cannabis cup winning and highly acclaimed Blue family of cannabis seeds.

Blackberry vs Blueberry harvest potential

Blueberry seeds are rated as Medium (‘M’) yielding. This might cause some growers to exclude Blueberry as an option. However, those that grow for themselves usually tend to prioritise quality over quantity. As such, despite the medium-yield rating, Blueberry feminised seeds remain as popular as ever. Quality never goes out of fashion!
Blackberry seeds tend to have a larger yield. On the other hand you also have a slightly longer bloom time. When it comes to autoflowering cannabis seeds, Auto Blueberry shares the same ‘Medium’ yield rating as her feminised seed sister. However, Auto Blackberry Kush is rated as an XL yielder. Anyone seeking heavy harvests from Auto Blackberry genetics should feel confident, especially in an optimised grow room with powerful LED lights.
Blackberry vs Blueberry cannabinoids and terpenes profile
The precise cannabinoid and terpene profile will depend on the phenotypes as well as the grow room conditions and grower experience. Under optimised conditions you should be able to bring the best out of both Blueberry and Blackberry strains.
In general, LED grow lights are recommended to serious growers looking to get the best out of their cannabis seeds and achieve 20% (or higher) THC levels. With inherently lower levels of heat production (and a superior light spectrum) LED maximises both cannabinoid and terpene profiles. Use of a UVA/UVB supplemental light, 2-3 hours per day for the final couple of weeks of bloom is recommended for those aiming for maximum THC levels.
Auto Blueberry has a terpene profile with high levels of (in order of prevalence) caryophyllene, limonene, linalool, beta myrcene and beta pinene. THC levels are high and CBG has been seen at elevated levels of around 0.8% in Blueberry buds.

Auto Blackberry Kush also packs a tasty terpene profile. The top 5 terpenes, in order, are limonene, beta caryophyllene, terpinolene, alpha pinene and beta myrcene. CBG levels have been seen around 0.85% and CBC is also slightly higher than average at around 0.3%.

Blackberry vs Blueberry potency and effects
One thing that both Blackberry and Blueberry fans will be in firm agreement on are the highly enjoyable effects from both strains. Blueberry perhaps better suits those that lean more towards favouring indica effects. It’s a great strain for relaxing, chilling out and enjoying the moment.
Blueberry is mainly indica, but a flash of sativa gives it the pleasant and rounded effects which have satisfied a generation of loyal repeat growers. Blueberry (and her countless descendants) are still as popular as ever in the coffee shops, social clubs and dispensaries.
Blackberry tends to better suit sativa fans. The sativa effects will feel more pronounced and the slightly more stimulating effects may suit those engaging in creative or artistic activities.
Cannabinoid quantities will of course be affected by the grow environment. But there are few complaints about potency or effects from either Blueberry or Blackberry growers.
If you have quality LED lighting with UVA/UVB supplemental lights and a stable environment you will be able to push the THC levels to the max. Ensuring your plants are kept in the nutrient ‘sweet spot’, without under/over feeding is always recommended.
When to pick Blackberry or Blueberry cannabis seeds?

Either Blueberry or Blackberry cannabis seeds would be good choices for most growers. Those needing a faster crop might prefer Blueberry feminised seeds, the indica genetics ripen perhaps a week or two quicker than Blackberry.
Blueberry enjoys a legendary reputation among old-school growers. Blueberry genetics are stable, dependable and have literally thousands of repeat growers. Some refuse to grow anything else and it’s worth remembering that Blueberry cannabis seeds have been the connoisseur's choice for several decades.
But photoperiod Blackberry has her own share of fans who adore the dark berry flavours, sweet taste and great bag appeal. Blackberry devotees who dislike the slightly lengthy 10 week bloom time (for the photoperiod version) really should consider growing some Auto Blackberry Kush seeds. With seed to harvest times in as little as 60 days, the speed of the auto version is hard to beat.
Autoflower seeds fully deserve their hard-earned reputation for speed, ease of growth and general all-round grower convenience. If you need a crop within a couple of months then either Auto Blueberry or Auto Blackberry Kush seeds would be perfect choices. Both strains are amongst Dutch Passion’s fastest growing cannabis seeds.

Auto Blackberry Kush, unlike photoperiod Blackberry, is more indica leaning. This doesn't detract from her quality, she took 2nd place in the 2018 Highlife Cannabis Cup in the autoflowering category. The judges were hugely impressed with the all-round performance, yield and potency. Auto Blackberry Kush only narrowly missed out on 1st place!
Kush fans will love Auto Blackberry Kush, the pungent trademark aroma raises excitement levels even before the buds have been vaped/smoked. Blue and purple hues in the dense buds only add to the sense of quality. These buds seem special even before they are consumed!
Auto Blackberry Kush is one of Dutch Passion’s best selling autoflower seeds.
The smooth, powerful effects give it a classy feel. Auto Blackberry Kush produces particularly potent buds with THC levels around 20% in good conditions. This makes her part of Dutch Passion’s Very High THC cannabis seed collection, home to some of the most potent strains Dutch Passion has created!

Auto Blueberry remains a staff favourite, deliciously fruity with a sweet taste and powerfully enjoyable effects which last several hours. The sense of anticipation before smoking a particular strain often indicates the real quality that awaits. Few strains have the sense of anticipation that Blueberry genetics offer. The popularity of Blueberry cannabis genetics has remained undiminished over the years, for very good reasons!
Blackberry vs Blueberry cannabis seeds for your next grow?

Choosing the next strain of cannabis seeds for your next grow is never easy! The fact that it is difficult choosing between two great strains shows you that each strain has their own merits. By the same token, making a bad choice isn't really something to be afraid of - since both options are good ones.
It may be helpful to first narrow your choice down to either feminised seeds or autoflower seeds. Remember that autoflower seeds are fast enough to grow outdoors and finish quickly even in temperate climates. In mediterranean climates, 2-3 successive outdoor crops may be possible each year. It may also help you if you first decide on which cannabis seed company you want to buy from. This may limit your choice to a smaller selection, making it easier for you to decide.
Do your research carefully, try to read some grow reviews and ensure that you are buying from a reputable cannabis seed company that has stood the test of time.
Good luck and enjoy your next grow! And remember, if you ever struggle to decide between several equally tempting strains then the Dutch Passion Seed Finder could make your decision easier. It simply asks you a few questions about your grow preferences, grow conditions, experience, amount of time available for a grow etc before making the right cannabis seed recommendations for you.
