About Sugar Black Rose Seeds


The winner of countless awards and widely recognized as one of the tastiest Indica varieties is a cross between legendary strains Critical Mass and Black Domina. Sugar Black Rose is among Europe and Latin America’s most prized cultivars, winning numerous accolades from 2010 to present day.

After experiencing this phenom at its full potential, you’ll understand the hype. Rarely does a strain possesses sweet, fruity flavors and undeniable sedative effects. The combination is a heaven-sent for medical cannabis users looking for better quality sleep, pain relief, or an anti-depressant who want an alternative to the gassy, kushy flavors of most Indicas.

Sugar Black Rose seeds also produce massive yields with an unusually fast flowering period and exhibit a short stubby stature ideal for indoor growing techniques. And thanks to its robust genetic profile, the strain has developed a natural tolerance to environmental threats like mold and mildew.

How to Grow Sugar Black Rose Seeds

Growing Sugar Black Rose is relatively easy due to its compact size and resiliency to infestations. However, you still need to optimize your grow environment to ensure you experience the strain to its full potential.

Grow Difficulty

Branch density is the most significant challenge you will encounter when cultivating Sugar Black Rose seeds. While the frame of the plant is short and stubby, branches can be on the thin side, putting the plant at risk if it is grown outdoors and subjected to windy conditions. We’ll cover multiple ways to promote healthy branch development and support your limbs in our Sugar Black Rose marijuana strain review.

You likely won’t encounter any other issues with Sugar Black Rose cannabis. The stain is highly resilient and adaptive to most environments. Follow our cultivation tips below, and you’ll easily produce award-winning flower perfect for cannabis extracts.

Optimal Growing Conditions and Climate

Your temperature and humidity range should remain moderate throughout the lifecycle of your Sugar Black Rose plants. We suggest maintaining a temperature range of 21°C to 26°C (70-80°F). The strain will adapt to variable conditions, but if you want to maximize yields and resin production, keep your environment consistent and right above room temperature.

Sugar Black Rose also thrives in moderate humidity. Therefore, keep your RH between 40% and 50% throughout development. Once you’ve reached the final two weeks of flowering, we recommend dropping your humidity down 10%. Lowering the humidity will increase your yield and encourage bud development as the plants reach full maturity.

Flowering Time

One of the most appealing characteristics of Indica plants is a shorter grow period. Fortunately, the Sugar Black Rose strain is consistent with its lineage and is ready to harvest in as early as 50 days.

If you grow outside and plant your Sugar Black Rose seeds in the spring, you’ll only have to wait until mid-September to harvest.

A quick veg and flowering period makes this cultivar among today’s most appealing varieties. With a 50-day flowering time indoors, you can pump out a significant amount of bud within a year if you manage your grow cycles efficiently.


Sugar Black Rose delivers incredible yields, whether it’s in a controlled environment, a greenhouse, or outside. If you are growing outdoors, you can expect nearly a kilogram per plant under optimal conditions. Indoor growers will experience less output at 450 grams per meter, but the quality of flower and shorter flowering periods make up for the lower yields compared to outdoor grows.

Supporting Sugar Black Rose Branches

As we mentioned, branch development is among the only potential threat to your plants. While the condition is rare, we suggest following the tips below to encourage healthy limb growth.

  • Building wooden supports to stabilize branches
  • Trellising
  • Sea of Green
  • Screen of Green
  • Adequate nutrients

If you are growing indoors, you likely won’t run into problems with your branches, but it’s not a bad idea to utilize a branch support system and ensure you are feeding your plants with plenty of nutrients to encourage healthy branch development.


The plant’s height is another significant advantage of choosing to buy Sugar Black Rose seeds. Due to its compact stature and a maximum height of only 60-80cm when grown indoors, the cultivar is an ideal candidate for growing techniques like Sea of Green and Screen of Green. These methods will maximize yields by increasing your total flower per square foot.

Outdoor plants will get much larger but still quite manageable while delivering impressive yields. Your Sugar Black Rose seeds won’t likely exceed 90cm when grown outside.

Resistance to Pests and Diseases

Sugar Black Rose is naturally resistant to devastating environmental factors like mold and mildew. In addition, infestations from pests like spider mites, aphids, and fungus gnats are rare. However, all cannabis grows are at risk of threats when left unmanaged. Executing best practices like optimizing temperature and humidity, pruning, and encouraging airflow will limit your risk of pests and disease.

We also highly recommend keeping a sterile grow environment to ensure you aren’t providing the conditions for mold and mildew. Even though Sugar Black Rose is highly resilient due to its robust genetic profile, environmental variables can still threaten your harvest.

Sugar Black Rose cannabis produces massive, dense buds, exponentially adding to the strain’s overall bag appeal. The flower is predominantly light green in color with deep, dark greenish purple fan leaves.

One of the most striking features of Sugar Black Rose is its unusually long pistils. While they are in the traditional burnt orange color, they protrude well beyond the flower’s surface, providing the strain with an unmistakable attribute.


While the strain’s lineage is overwhelmingly Indica, as are the effects and plant structure, it gives an unusually sweet, citrusy fragrance. The smell is refreshing and uplifting, but the dank, skunky aroma emerges as time passes, revealing Sugar Black Rose’s dark side. Its enigmatic scent offers Indica smokers a breath of fresh air as most varieties lack a bright, uplifting, fruit-forward aroma.


The flavor perfectly complements its scent, delivering a sweet and fruity initial burst of energy, then leaving a trail of skunky, pungent notes. You’ll notice a more pronounced flavor best described as fresh, ripe, juicy purple grapes. The bold flavors of Sugar Black Rose make this strain an excellent option for cannabis concentrates such as oil, wax, shatter, and live rosin. Your distinct flavor profile will shine even brighter when the compounds are removed from the rest of the plant matter.

Cannabinoid Content

At 25% THC, Sugar Black Rose is not a strain to take lightly. While the mid-20s isn’t unusual in the current state of cannabis genetics, it’s plenty to make even the most experienced smokers tap out. In addition, the strain possesses an abnormally heavy high, making a seemingly moderate cannabinoid content far more intoxicating.

Dominant Terpenes in Sugar Black Rose Cannabis

While Sugar Black Rose has an impressive terpenes profile, caryophyllene, myrcene, and linalool are the most abundant. Each is common in cannabis flowers and has distinct flavor, aroma, and benefits.

It is unclear if terpenes directly interact with the ECS, the subject is a highly debated topic within the scientific community; however, experts agree that terpenes improve the overall cannabis experience. As we shift away from a market that only cares about THC content, strains like Sugar Black Rose are increasingly in demand.

Sugar Black Rose Strain Recreational Effects

Sugar Black Rose is prized for its ability to induce a deep sense of relaxation and tranquility. The strain is often used by recreational users looking to unwind after a long day, as it can help calm the mind and body, making it suitable for evening or nighttime use. Many users report feeling a sense of physical and mental relaxation, with tensions melting away and stress levels decreasing.

In addition to its relaxing properties, Sugar Black Rose can provide an initial uplifting and euphoric effect. Users may experience a subtle mood lift in the first hour of enjoying the strain, feeling more content and at ease. This combination of relaxation and mild euphoria can create an enjoyable experience for those seeking a laid-back and mellow vibe.

Another notable effect of Sugar Black Rose is its potential for enhancing sensory perception. Many users report a state of heightened awareness, with an increased appreciation for art and other sensuous experiences. Varieties that invigorate the mind make activities such as listening to music, watching movies, or engaging in creative pursuits more enjoyable and immersive.

Sugar Black Rose’s Medical Potential

Beyond its recreational effects, Sugar Black Rose also shows a high potential for various medical uses. The strain’s unique combination of cannabinoids and terpenes may offer therapeutic benefits to specific individuals.

Below are some potential medical applications you could experience when using the strain.

  • Pain relief: The strain may help manage different types of pain, including chronic pain, neuropathic pain, and muscle soreness.
  • Anxiety and stress management: Sugar Black Rose’s calming effects may benefit individuals dealing with anxiety, stress, and related mood disorders.
  • Sleep aid: The sedative properties may make it useful as a sleep aid for individuals struggling with insomnia or other sleep disorders.
  • Appetite stimulation: This well-known quality of potent cannabis varieties may be an application for individuals with poor appetite due to medical conditions such as cancer,
    HIV/AIDS, or other conditions that result in appetite loss.
  • Mood elevation: Sugar Black Rose’s euphoric effects may help manage symptoms of depression or low mood.

While Sugar Black Rose is widely revered for its medical potential, it’s important to remember that marijuana is not an approved treatment for any of the conditions mentioned above. There are countless anecdotal accounts of strains providing these benefits, but we still recommend speaking with a doctor before you use marijuana as a treatment.

Adverse Effects of Sugar Black Rose Marijuana

When used in excess, potent strains like Sugar Black Rose have potential adverse effects. If you are new to using cannabis, you could be at a higher risk of dry mouth and eyes, dizziness, and fatigue.

Avoid these side effects by consuming the strain in moderation, drinking plenty of water, and enjoying with a friend.
