The Blue Crack Strain: A Vibrant Hybrid with Creative Vibes
Blue Crack is a berry-infused hybrid with a 50:50 indica-to-sativa ratio and THC levels of up to 24%. The offspring of Blue Dream and Green Crack, its fine-tuned lineage offers a hit of focused, energetic cerebral buzz paired with a mellow, relaxing body high. Many fans of this strain describe the experience as mentally stimulating, creative, and clear-headed, making it a popular choice for daytime use or any moment you want to feel inspired.
This vibrant strain is especially fitting for cannabis enthusiasts drawn to moderate-to-high THC levels and vivid psychoactive effects. Blue Crack's cannabinoid profile is further bolstered by a complex terpene profile, which exudes a sweet berry flavour and aroma with subtler notes of citrus, spice, and earth.
Add all these characteristics up, and you're left with a multifaceted experience full of creative energy and mental clarity. Given its enticing mixture of traits, it's no surprise many Canadian cannabis growers leap at the chance to add Blue Crack seeds to their gardens.
Growing Tips for Blue Crack Seeds
Blue Crack is a versatile strain that can be grown both indoors and outdoors, and is suitable for beginners. Below, we've highlighted some key tips to help you take the very best care of your Blue Crack plants and inspire your cannabis garden to reach its full potential.
Dial in Your Growing Conditions
When grown outdoors, Blue Crack thrives in a warm, sunny climate. By keeping temperatures between 21–27 degrees Celsius, growers can help ensure their plants can enter the photosynthesis process, and in turn, produce the most resinous buds possible. Proper temperature ranges also help fend off issues such as mould and mildew, which are more likely to occur if your growing environment is too hot or cold.
Blue Crack also loves good air circulation. A gentle breeze helps prevent issues such as mould and mildew, and as a bonus, helps strengthen your plants' stems, allowing them to grow healthy and strong. Clip-on oscillating fans work well in grow tents, while box fans can provide adequate airflow for larger spaces.
Cooler temperatures at night stress your plants in a controlled way — resulting in more vivid blue and purple hues. Growers can also enhance this strain's trademark colouration by lowering nighttime temperatures by 3–5 degrees Celsius.
Germinating Your Blue Crack Seeds
Our germination guide is the perfect way to kickstart the growing process for your Blue Crack seeds. The process is easy to follow and requires only a few household items, including a glass, a plate, and paper towels. Begin by soaking the seeds in water for up to 24 hours, then nestle them between damp paper towels on a plate. Once you spot taproots, your Blue Crack seeds are ready for planting! As a bonus, growers who use our germination technique can cultivate confidently, knowing our industry-leading germination guarantee will protect their seeds.
Yields
Blue Crack can be quite generous during harvest time. Indoor growers using the right techniques can expect yields of up to 14 ounces per square metre. Outdoor cultivators tend to fare even better; when cultivated with care, the Blue Crack strain will produce even higher yields of up to 16 ounces per plant.
Flowering Time and Harvest
Blue Crack has a relatively efficient flowering time of approximately 56–63 days when grown indoors. Outdoor growers are encouraged to plant their Blue Crack seeds in late spring or after the last frost, which helps avoid damage from chilly weather — an important consideration across many Canadian growing regions. By late September to early October, the buds typically develop a frosty blue-green tone, appear particularly dense, and have milky, amber trichomes — meaning your plants are ready to be harvested.
Dominant Terpenes in the Blue Crack Strain
This strain is famous for its berry-like fragrance and taste. Many fans are drawn to its essence of ripe blueberries, with hints of spice and a floral, herbal finish. The Blue Crack strain's dominant terpenes include pinene, known for its fresh, piney quality, as well as myrcene and terpinolene, which contribute sweet, berry, and herbal notes, respectively. Together, these terpenes produce Blue Crack's distinct and memorable flavour and scent.
Dominant Cannabinoids in the Blue Crack Strain
The Blue Crack strain has generous THC levels of up to 24%. As the dominant cannabinoid in this hybrid, the THC content creates an imaginative and psychoactive experience defined by its creative energy, knack for elevating mood, and ability to enhance sensory perceptions such as sight and sound. While other cannabinoids like CBG are present, their levels aren't potent enough to create noticeable effects. In general, higher THC levels, such as those of Blue Crack, are best-suited to cannabis enthusiasts with some experience and a tolerance for stronger highs.
