Blue Hash is a feminised cannabis seed with the mark of the Afghan mountains burned into her soul. At Dinafem Seeds, we felt the urge to create a tough strain with the true power of nature that would offer the cannabis growers living in regions with difficult, cold, and humid weather conditions the chance to grow blithely. Obtaining a quality product in such environments has always been quite an impossible task but now, besides possible, it can be done with good yields and in a remarkably short time.

A miracle? Not at all, it's just the result of a job well done by our team of breeders, who set to work and quite rightly decided that working with two top genetics such as California Hash Plant and Blueberry could lead to a very interesting strain. An all-around Indica-dominant (60%) hybrid that is just perfect for the elaboration of high-end hashish and resin extractions.


Blue Hash turns into dense and sturdy plants with jagged leaves. Their size will depend on the growing conditions (pot, substrate, growing method…) and on the grower’s aspirations. Outdoors, Blue Hash can reach heights of up to 3 meters but, if the space is limited and we decide to grow indoors, a rather small pot can be used and so the plant won’t stretch in excess. Her Blue legacy is the incredibly beautiful appearance she acquires at the end of the flowering if the temperature drops by 10ºC at night, boasting a marvellous purple and violet colouring.


When it comes to the yield, Blue Hash is a cannabis strain that leaves no one unhappy because her productive capacity is more than satisfactory, delivering 475 g/m2 indoors and 1100 g/plant outdoors. And it’s not just any product… When, by early/mid-October, plants are ready for harvest outdoors, we can already discern what’s about to come. But once cannabis growers start harvesting, their eyes twinkle with excitement at the thought of the top-quality extractions and hash they could elaborate with such dense and compact buds covered in so many trichomes.

Aromas and flavours

Blue Hash showcases the typical organoleptic traits of pure Afghan genetics. In this case, this cannabis hybrid presents a very intense hash scent accompanied by hints of earth and berries that make it even richer and more special.


The 12-16 % THC content of Blue Hash provokes a very potent, long-lasting and relaxing Indica-like buzz. At first, a physically soothing sensation takes over your senses and leaves you fully relaxed. This marijuana plant is also suitable for a wide variety of therapeutic uses such as for alleviating anorexia and muscle tension. An incredible Indica jewel that your collection shouldn’t do without!


Blue Hash is a real beast and she'll thrive wherever you decide to grow her. A survivor that can be grown in the mountains or in hostile climates because, unlike most Indica strains, she copes extraordinarily well with moisture and extreme cold. She’s so tough that anyone can grow her, no matter how inexperienced the grower is.

It’s only necessary to remember she’s not particularly greedy, so a standard fertilization will be enough for her to thrive. In short, she’s a great choice for those living in harsh weather conditions as well as for those with little experience in the growing field.  Top-quality results in record time. What more could one desire?

Dinalab Analysis


Total amount of terpenes*: 1.224%

*Cannabis contains over 100 terpenes. These compounds create the aroma unique to each strain and can interact with cannabinoids. This report refers only to the 15 most abundant terpenes in this strain.

These results have been obtained by liquid chromatography coupled to a UV-visible HPLC Detector (HPLC-UV/VIS) for identifying the cannabinoids and by gas chromatography coupled to a flame ionization detector (GC-FID) for the collection of terpenes. The equipment has been previously calibrated and quality control samples were run to assure the accuracy of the results. The data shown here is the average of samples coming from several plants grown from seeds by different growers.

The data contained within this report was collected in accordance with the requirements defined by the United Nations Office on Drugs and Crime in their Recommended Methods for the Identification and Analysis of Cannabis and Cannabis Products. We hereby attest that the information contained within the report has been reviewed for accuracy and checked against the quality control requirements for each method.

    I bought 3 seeds of blue hash feminised and all 3 died after. Tap roots appeared no problem but died after a few days and never even grew a seedling. A bit of money spent with p & p so not best pleased.

  4. Awesome

    5 out of 5
    You get what it 'says on the tin': vigorous and easy to grow, resistant to various usual issues including mould. It also clones well, and responds positively to topping and low stress training. Bushy and relatively short: I had no real issues growing in a small hidden space. Nice sweet blueberry taste on the inhale and a pleasant hashy taste on the exhale, with a good strong stone. This truly is a beautiful smoke. I had a 100% germ rate too and Dinafem is now my seed bank of choice which I recommend whenever I get the chance.
  5. Gorilla: an all other seed.

  6. Blue Hash a tasty strain

    5 out of 5
    I hadn't grown in years and decided it give it a go. A buddy hooked me up with a couple different beans from Dinafem. One strain being the Blue Hash. Needless to say the Blue a Hash turned out to be the choice mother. Blue Hash was easy to clone, the clones were beautiful and just as vigorous as their mother. The clones were under a 400watt HPS for 60 days in a 4x4 tent (first time using a grow tent). I went top feed hydro in buckets with rock wool and hydro corn. I Veg'd too long and quickly ran out of room during bloom. My fault live and learn. I still ended up with 9 ounces of primo herb ( and I'm convinced I could have gotten more). The buds were nice and compact and had a sweet blueberry aroma. The buzz was nice, relaxing and was great for unwinding after work. I ended up making canna butter and wow. I was tripping balls ( way too much butter in the one batch of cookies). Great strain... would love to give it a go again in the future.

  8. Just like it says.

    5 out of 5
    I have this in my tool box, I have two pheno's still doing test on the two.They grow very close to exact, except one grows a little more open, little more sativa influence. The other perfect 2 main colas topped once.I have kept these two for awhile now,always the same. Well any way, easy grow, normal 10 day clone.It is just like they say, grows like a indica.Has that blueberry taste, smells are in there.Indica body stone for sure with nice mix of head high.I smoke this at night, relaxing and mind still gets a nice jolt.

    ordered 3 blue hash, 3 industrial, 1 free critical+blue hash was the VERY BEST BY FAR and was reserved mostly for personal. the other two were great too, but the blue hash is something very special.indoors organic 2x 400 watt HID60-64 days to flowerphenotype smelled just like blueberry strain, with hints of the "hashy/skunky/pungent" odor. amazing taste and smell after only days of curing.lots of resin, tightly packed buds. even the water leaves had crystals. when compared to the "blue dream" strain, there is no comparison. blue hash is a masterpiece and i have tried several strains. the potency rivals sour diesel and trainwreck strains while holding on to the blueberry taste. the high was very uplifting and euphoric and not to sleepy or heavy, yet very long lasting. expect 1/2gram per watt in a good growing environment.i hope dinafem carries this strain forever.

  11. hash plants

    5 out of 5
    Recently bought a pack of 5 blue hash feminine beans going to crack them in the next day or so I hope they are as good as dinafems california hash plant as I grew those in a previous grow and they where bangin some of the nicest flavours to be found and the resin production second to none so all going well I will repost with a final report on the blue hash.
  12. Kids need to be treet good, especially with tooth

    5 out of 5
    Children's tooth development begins while the baby is in the womb. Teething usually occurs between the ages of six and nine months. Children usually have their full set of 20 primary teeth (milk teeth, baby teeth or deciduous teeth) by the age of three years. At about the age of six years, the first permanent teeth erupt (push through the gum).
