Sugar Black Rose is an indica-dominant feminized hybrid, 80% indica and 20% sativa, with a sweet, fruity and floral character over an earthy, hash-like base. Delicious Seeds, the breeder that created it from Critical Mass and Black Domina, lists THC at 25%. It is rated an easy grow and flowers in about 7 to 8 weeks.
History & lineage
Delicious Seeds bred Sugar Black Rose by crossing Critical Mass with Black Domina, and it was already on sale in 2011 as part of the breeder’s Fast Indica Line. The Black Domina side was the breeder’s own plant: a 2020 version of its page called it “our highly-prized 1998 Black Domina mother”.
Both parents have long histories of their own. Mr. Nice Seed Bank, which bred Critical Mass, gives its pedigree as a particularly heavy Afghani crossed with the original Skunk #1, and calls it a reworked version of an old breed once known as Big Bud. Black Domina is a four-way hybrid: Sensi Seeds describes it as a mix of Northern Lights, Ortega, a hash plant and Afghani SA, and Leafly lists the same four strains.
Aroma & flavour
Delicious Seeds describes a sweet, fruity smell and a taste of ripe grapes and flowers with a hint of skunk, with a sweet and spicy mix on the first draw; its taste notes include floral, fruit, grape, mango, skunk, spices and sweet. Leafly users most often report sweet, rose and flowery flavours, followed by earthy, and Leafly describes the aroma as a pungent, earthy musk that resembles hash. Leafly’s lab data lists caryophyllene as the most abundant terpene, followed by myrcene and linalool; our guide to cannabis terpenes explains how they shape a smell.
Effects, as users report them
Delicious Seeds describes the effect as immediate and very relaxing, close to narcotic, with some cerebral stimulation. The boxes show Leafly users’ reports for Sugar Black Rose, most common first. Dry mouth and dry eyes are the downsides reported most, followed by dizziness, and a few users report headaches, anxiety or paranoia. Effects vary with the person, the dose and their experience, so if you are new to cannabis, start with a small amount.
Growing Sugar Black Rose
Sugar Black Rose is a feminized photoperiod plant: it stays in vegetative growth until the light drops to 12 hours a day indoors, or until the days shorten outdoors. Delicious Seeds gives a flowering time of 50–55 days (about 7 to 8 weeks) indoors and an outdoor harvest in mid-September in the Northern Hemisphere; our seed-to-harvest timeline shows how that fits a full grow.
It is rated an easy grow. The breeder lists yields of about 450 g/m² (1.5 oz/ft²) indoors and 900 g (about 31.7 oz) per plant outdoors, and rates the plant’s height as medium. It describes the plant as dense, wide and low indoors, with room to branch out when it has the space, and says it grows considerably bigger outdoors, in big pots or straight in the ground. Near the end, judge when to harvest by the trichomes rather than the calendar.

Read Reviews from our Customers
Sweet, Heavy, and Relaxing
Sugar Black Rose came out dark, sticky, and super fragrant. Smell was sweet and floral with a deep earthy note underneath. The smoke is smooth and calming, and the high settles into a heavy body relaxation with a mellow headspace. Great night strain for winding down or getting some solid sleep.
Sweet, Sticky, Sleepy
Sugar Black Rose was gorgeous to grow—deep green leaves, thick colas, and that sweet floral aroma just kept getting louder. The high is smooth and relaxing—melts your muscles and clears your head. Great nighttime strain, perfect for winding down. Sweet on the nose, soft on the brain.
Sweet, Stinky, and Built for Naps
Sugar Black Rose? More like Sugar Black KO. This thing smells like a mix of candy and dank basement, in the best way possible. Grew short and wide, like a little green couch potato just waiting to be smoked. The buds were dense and stupid sticky. One joint in and I forgot what I was talking about mid-sentence—just blinked and suddenly I was horizontal. Great for sleep, snacks, and forgetting your to-do list. Absolute gem if you’re trying to vibe, not hustle.
