Black D.O.G.


An energy-packed strain

A real delicacy for Kush-lovers

Black D.O.G. develops a beautiful marijuana plant derived from the cross of two classic northern Californian strains: Blackberry Kush and Emerald Headband. This medium-sized/big plant, oozing vigour and quality from every pore, can make the room turn into a tropical paradise. In fact, it must be noted that, during the 12/12 light cycle, the plant can stretch up to a 30%. Due to its short flowering phase, the likelihood for the plant to be affected by mould or diseases is significantly reduced. Breeders of all levels are sure to fall for the extraordinary yield of this plant.

A wide range of sensations

The pet strain of the most demanding users

This cannabis hybrid showcases a really intense mixture of flavours and aromas, with notes of grapes, berries and oil. Its initially cerebral effect turns more physically relaxing as time passes by. The strong and long-lasting high it provides will delight each and every person around.

  2. 5 out of 5

    I’ve been growing this strain for about a year, and it is definitely a favorite. Easy to grow, great taste and nice yields. Puts on some beautiful colors late in flower and it’s a fast finisher. You won’t be disappointed!

    I bought a bunch of individual seeds from the Humboldt range, just to see what they were like. Black dog was one of 4 strains I grew at the same time, and it was a beautiful plant. It has great structure, not many leaves to remove, and the buds are amazing to watch develop. The smells are complex, a bit like a good champagne, sort of red grape/berry-ish. Lovely stuff when you open the jar! I think everyone should grow this strain, I enjoyed it so much I bought a 5 pack for the next grow. Great work HSO team.

    This was one of the most beautiful fully grown plants I have ever personally seen. Grew very quick under 300 watt (145 true watts) LED, grown in soil and during the perfect time of year for where I’m located. The coloring on this one is incredible. The deepest purple I have seen, almost looks black, then all the sudden there is some blue and pink and of course green, further down, it seemed like the LED brought out the colors a lot more, I noticed the canopy was the deep, dark (black) purple, the further from the light or any leaves or buds that weren’t getting the same amount of direct light. The LED also has UV and infrared, maybe that helps to attribute to the color. Grown by he sun, it would naturally get those spectrums. Incredible smell and taste to match. I was very impressed with the genetics and am looking forward to trying a few others. I highly recommend this one, I will be doing it again when the weather is right.

    Bought some Black D.O.G seeds
    Germanated a few that night the next morning they all poped beautiful. Thick roots now there in pots and they grow amazing. Fast lovin it

  15. 5 out of 5

    It grows kind of spindley out of the shoot but when it hits the water it takes off. It has reasonable but not a big amount of side braching and concentrates on doing one or two main colas. Sort of has that Christmas tree growth pattern. Side growth is on the bottom half of the plant and the colas go vertical. I had one I topped and one I left alone. The topping had two buds about 1/2 the size of the one big cola on the uncut so I’m not sure topping is necessary. Fills up a cola nicely. Much like an indica but just a little looser from the sativa influence. No need to go heavy with the nutes. It likes a steady 3/4 dose. If you force it too much it will spot a little but not a lot. When you switch to flower the dime size buds appear quickly but they don’t grow much until you get to about week 7 of flower. They start out with a slow fill and it builds thoughout the finish. It was one of those one more day, one more day kind of strains. I let it go until I had about 50% amber.

    Smoke wise it has a big up with a comfortable down. You feel like doing stuff and are just smiling a lot but you’re not stressed. Real mellow smoke that you can kind of adjust to what you need. A good Party smoke. Want the happy part – a joint or bowl will do just fine. Need to relax a little more – power hit that sucker for awhile and you’ll get there. Vapes real nice and taste spicey/flowering with a semi-sweet finish. Last for at least a couple of hours and lets you down slowly. I lot of “where was I” in this strain

  16. 5 out of 5

    beautiful strain the frost content was out of this world but its TALL TALL to tall for my situation but for all you scroggers out there you should try this out she got a lovely colour when she finishes and packs a good punch when dried and cured. ans same as all the HSO strains ive tried which is most of them now there so vigorous,healthy and effortless to grow just watch out for her stretch folks

    Bought 5 black dog beans , all 5 popped 2 pheno’s, both are amazing , skeptical on the flowering time 2 weeks into flowering but the next 4 proved me wrong quickly turned into stinky frosted goodness , smell and taste are exactly as described, a home run HSO thank you for the strain

  18. 5 out of 5

    Surpassed all my expectations. Great smoke and high. Will be ordering again

    I love the black dog unfortunately I only got 1 to pop out of ten and it took over 2 weeks 🙁 which I was very disappointed about I’ve only ever had this happen to me once before and that was with some really old seeds that had been in the freezer for some time and I didn’t use hormones on them to give them the kick start they needed. Everything else I got from you guys came out great I just think I got bad luck and was given a bad bunch of black dog seeds 🙁 I would really love to try this strain again and I’m going to buy another Bach of amherst sour diesel as that strain rocks!!

  21. 5 out of 5

    Great strain!

  22. 5 out of 5

    I am currently growing this now after buying the seeds from Product Earth in the U.K. and wow that aroma is something else! Along with the high sugar content frosting up the leaves and the buds nicely! I have around 14 days maybe a little bit more left on the two lovely females and then I will get the pleasure of tasting these gorgeous looking buds! Well done HSO! Another fantastic strain!

  23. 5 out of 5

    Black Dog is a must have for true cannabis connoisseurs that enjoys great aromas and loves the hard hitting effects,Black Dog is a must have for me

    Growing now clones very easy can’t wait

  25. 4 out of 5

    Had a little trouble with the crack of these, 2 of 3 failed. The 3rd is a beautiful distinct, subtle kush smell and bud formation, with a little sativa stretch to it. In late flower and due to a temperature drop the bud leaves are turning purple-y black and individual calyxes a bright purple. Smells sweet and spicy, not the most knockout stink but I’m sure the flavour will translate incredibly.

    Already reviewed Black D.O.G, however after curing & put in glass jars for almost 4 months, the Aromas & taste are absolutely superb!! Earlier there was as someone mentioned a drowsy feeling but this seems to go after a cure, most likely due to some THC degradation during the cure as always happens making it quite cerebral. When freshly dried Black D.O.G is incredibly strong & absolutely stinks when you smoke it & in a Baggie . Just bought 20 more its that good.

    This lovely little indica gem is just as described. Delightfully quick flowering, amazingly fast veg. state, lovely frosty purple fruity and deadly potent flowers that are fit for a cannabis cup championship.

    Salut, j’ai utilisé cette souche pour ma session outdoor 2016. C’est la première fois que je plante des graines HSO et je dois dire que j’ai pris mon pied à voir pousser cette Black DOG. Mise en semis en Avril, repiquer en pleine terre mi mai . Le départ c’est fait tranquillement jusqu’en juillet ou cette merveilleuse plante à continuer sa croissance de façon explosive. Au début de la période de floraison ( 15 août ) je pensais que son développement se calmerait, mais que ne nie, mi octobre au moment de la récolte je me suis retrouvé avec trois spécimen de plus de 3 mètres qui ont pris une couleur pourpre impressionnante des buds pleine de trichrome et de jolis petits filaments orangés. J’ai récolté sur ces trois spécimens 1750 gr de matières végétales sèches. …… Ces plantes ont été élevé uniquement par du TCO élaboré selon les différents stades de croissance et de floraison. Quant à son effet on reconnaît son effet indica, géniale pour se relaxer après une bonne journée de travail. En somme essayez cette souche, prenez en bien soin et vous serez récompenser de tous vos efforts.

    High quality strong indica. Great for pain, insomnia, and stress. Expect couch lock and drowsiness. Nice dense buds covered in crystals with highlights of purple. Must have strain in every garden for sure!!

  33. 5 out of 5

    Beautiful plant I would love to run this strain.

  34. 5 out of 5

    I am currently growing Black D.O.G. I originally ordered a single seed. I took a bunch of clones and flowered the mother It is a great plant. Some of the best flavor and potency! Also clones root quickly Everyone who tries it is in love with it! Fast finisher too!

  35. 5 out of 5

    I am growing the Black D.o.g. and Kief Sweats Ewe2. Theyre the best 2 plants,in my garden. The Black D.O.G. with a little topping/supercropping,she has arm after arm full of huge frosty colas. Its beginning to turn red in the leaves,and it is just massive! Now the Ewe2 that is growing with the Black D.o.g.,is very short and very bushy. Its the only in my grow to be frosty with trichomes in only 3weeks of flowering. Thats AMAZING!!!!!!!!!!!! This is going to be a very special plant,indeed. It stinks to high hell,but it is going to be extremely narcotic bud,i can tell. I also am growing Sour Blueberry. I can honestly say,the Humboldt seed products are second to none. Theyre the highest yielders in my garden, and the smell and the potency is always on point!!! If you want to be assured that you get the most out of your seeds and grow equipment, remember, a lot of factors are in the genetics. And Humboldt seeds,are available through many seed banks. Trust me,the money is miniscule compared to the fine,finished product. Try them,you won’t be sorry.

    Black Dog is another hardy plant from HSO. The plant stay squat and branchy like an indica and has great structure. It benefits from a topping and training. In flower she springs up and with the phenol I hunted stayed a beautiful dark green. By the end of flower she became lighter green with fan leaves eating up all their food and turning an autumn yellow. At this time was when I saw this particular phenol start purpling out on the tops of the buds. I Still have 9 more seeds to pop to look for that all purple pheno. The buds are nice and round and very beautiful looking and smell is great! Black Dog and Bio Vortex will rock your socks off with this one!

  37. 5 out of 5

    It has the perfect mixture of flavors and smells from the parents Sweet Berry and sour kushyness! The high from the strain really sweeps away your troubles, not too heavy not too light. Along with very uniform phenos, this is definitely a strain I’m going to run again

  38. 5 out of 5

    The color on this is amazing !!! My garden is straight black! I love the nug formation on this strain! Deff a must have!

  39. 5 out of 5

    Beautiful Colors. Love the Darkness…

  42. 5 out of 5

    Great Strain, easy to grow, branches are full of Trichomes. Taste & smell are really nice but different to most Kush crosses, sometimes you get a feint taste of berries with a gassy/fuel taste, unusual! I cut at about 56-60 days & plants were just starting to show purple hints, a little longer or drop in temps would defiantly bring out the Purple more.

    A highly recommended plant, I’ve already got more Seeds for another grow, I like it that much, hard not to like !!

    Great work from everyone involved, I’ve yet to run a HSO strain I didn’t like. PAK next, yum !

  43. 5 out of 5

    I am growing both Black D.O.G. and Sour Blueberry. They’re both beasts and I only vegged for 5 weeks. They’re only a week into flour but they’re bushy and smell incredible. No colors except lush green,so far but I have 4-Black D.O.G.s and 3 Sour Blueberry left. Now that I figured out how they grow,I am definitely begging for 60 days and some topping,super-cropping and L.S.T. ing. I want to see the real potential which is there if you do it right. They like to eat,just like me. And have potential to get tall and broad like me. I want to get a pound per plant. I will,just watch out for pics in High Times,lol. 5 stars,baby!!!!!!!!!!! I love Humboldt seeds but more so,the great meds that come from the seeds!!!!!!!!!
