Black DominaL.A OGCritical Kush

Hardy strain with good production and very high THC levels.

Black Sugar is an 80% indica strain that develops a round, bushy structure with strong lower branches. It has a short flowering time, a good yield and a typically indica effect. It is a 3-way cross of Black Domina x L.A OG x Critical.

This plant grows well outdoors as well as indoors due to its robust nature. Its range of cultivability is quite large due to the short flowering period - it is ready to harvest in the northern hemisphere at the end of September or early October at the very latest. In this environment it can grow to be 250 - 300 cm. tall with yields of 800 gr/plant. Indoors flowering will only take 50 - 55 days with superb yields of 600 gr/m2.

Black Sugar has a very fruity lemon and orange taste with pronounced skunk notes. THC levels are very high with low CBD giving an effect that is powerfully narcotic and an exceptional strain with which to relax and do nothing but dream.

Customers report mixed germination experiences with this strain, with many achieving excellent sprouting rates and vigorous seedling development under proper conditions, while others encountered poor germination, slow sprouting, or weak seedlings that failed to thrive. Those with successful germination consistently praise the resulting plants for their vigor and growth potential, though some noted inconsistent outcomes even within the same seed batch. Overall, while the strain produces strong plants when germination succeeds, reliability in the germination phase remains a notable concern for a significant portion of growers.

The 8 black sugar seeds planted had a 0% germination rate. Not impressed . Black sugar is my favorite strain that I grew last year . The 11 other strains I purchased had a 90% germination rate. I would not recommend black sugar strain from seedsmans at this time. I am disappointed.

I'm sad to have to give a low rating for the black sugar specifically. Cause I bought a variety and the other is doing really good . I bought the buy 5 get 5 deal on the black sugars and purple ghost candy . Also came with the 2 freakshow from hombolt and 3 more of each og kush , white widow , and critical 2.0 auto . Unfortunately 1 one black sugar germinated . However it has a weird malfunction but a good one . It at seedling stage split into 2 main stems growing outwards from each other . It's really pretty and no topping or training has been needed yet . Now I popped 3 purple ghost candy and they all germinated and are doing really well! Visually as good and faster than my snowcaines even . So I'm impressed with those . Then only 1 of the 2 freakshows germinated but the one that did is awesome . I've never seen something so perfectly structured. It's as if it was perfectly trained on its own and has a perfect even canopy. Then it took me 2 seeds that only 1 germinated of the critical 2.0 I started for a friend . But it's doing good . It's a shame about the black sugars but I'm hoping it's just one accident and that my other 5 pack will make up for this one . I also haven't reached out to seedsman about this yet . Seems legit so far so I would imagine they will honor their germination guarantee. Other that that I'm looking forward to growing all the other seeds I got from them . 👍 Here's some pictures . Perfectly structured freakshow . A couple pictures of the black sugar . Then the small one is the critical auto I started after the rest for a friend . And the purple ghost candy are the outside picture . And the group picture are mainly of my 5 snowcaines ,1 sparkleface in 10 gallon mesh , and the black sugar and freakshow to very left in 7 gal mesh . Happy growing 👍🤠

I set 10 black sugar seeds up to pop with 3 blueberry, and 3 bubba cheesecake. Only 5/10 black sugar popped. Blueberry and bubba cheesecake were both 3/3 and have taken off. All very strong plants. One of popped black sugar seedlings died. The 4 that didn’t die are weak and behind the other strains. Despite some of the good reviews… I don’t recommend this strain.

I don't really want to give a star rating until I try germinating the other 2 seeds, but my first seed didn't germinate. I currently have 5 other plants going. All from seedsman. All of those germinated and are doing fine. Love seedsman just think I got a dud on this one. It happens.

I had a pest problem which delayed things. The yield was 65g off one plant indoors, I only gave it 2 weeks veg, four weeks would have been better for the yield. Did two harvests after 8 weeks 12/12, then again three weeks later in the hope it might get more potent, but the longer time risks hermaphrodites. It sat next to an amnesia haze, both ended up with a few seeds and reduced potency, while another nearby was unaffected. I think it was black sugar which went hermie, I didn't find any pollen sacs so can't be sure. That is probably my fault for over stressing her. Still good as a daytime vape, relaxing, easy to grow, but don't stress her too much.
