Blueberry Cupcake
Hybrid
24% – 28% (Some phenos test up to 34%)

Blueberry Cupcake or Hybrid is a strain that typically contains THC levels between 24% – 28% (Some phenos test up to 34%) and CBD levels ranging from < 1% (Trace amounts). Known for its Blueberry Slushie, Cake Batter, and Raw Fuel profile, this strain has a growth expectation of being Medium-Tall (Explosive lateral and vertical growth) in height, with a nutrient demand that is High; specifically high Nitrogen (N) during Veg and Phosphorus (P) in mid-Flower..
This Hybrid is of the Genetype: Blueberry Muffin x Wedding Cake. The Blueberry Cupcake strain has 3 phases of the growing cycle.
The first phase is the Seedling Phase. Once you have decided to grow Blueberry Cupcake in either soil or hydroponiclay, the ph levels need to be monitored. The ph level desired by Hybrid is 6.2 – 6.8 and 5.6 – 6.2 hydroponically. During this infancy stage, Blueberry Cupcake needs to maintain a target temperature of 75°F – 82°F (24°C – 28°C) for 2 to 3 weeks. Once the seed germinates, it will sprout it's first set of round leaves, or the cotyledons. If you are able to maintain the target humidity of 65% – 70%, the iconic serrated leaves will just begin to show themselves. During this critical Phase 1 of the Hybrid growing cycle the plant is establishing a strong root sytem. Beginners often over water these fragile seedlings. Do not drown your seeds. You seedling Blueberry Cupcake needs care and gentle light. The recommended light cycle for growing Blueberry Cupcake is 18/6 or 20/4 for the first cycle, which should last .
The next is the Vegetative Phase. The Blueberry Cupcake will focus entirely on size and structural integity. The temperature needs also change for phase 2. If a target temperature of 70°F – 78°F (21°C – 25°C) is maintained and a target humidity of 45% – 55% is achieved, the Hybrid will grow stems, branches and plenty of large fan leaves. This Blueberry Muffin x Wedding Cake is trying to build it's own solar panel of leaves to absorb energy. It is critical to maintain a proper light cycle of 12/12 for the entire phase 2 schedule. This consistent energy will help plant grow bigger without producing flowers, focusing it's energy on growing tall and strong. Blueberry Cupcake is at it's most resilient and may grow quickly. As phase 2 comes to an end, it may be topped or tied down, as it's training suitability is considered High; responds excellently to LST, Topping, and SCROG..
The most exciting phase, when growing Blueberry Muffin x Wedding Cake is the Flowering Phase. The plants adulthood lasts . It is at this phase that the light cycle changes for the last time. Blueberry Cupcake will produce the most flowers when the light cycle is 12/12. Keep the temperature and humity controlled at 65°F – 72°F (18°C – 22°C) Essential for purple coloration. and 35% – 45% (Dense buds are prone to mold/mildew). so you can really watch this plant strecth and almost double in height. It will want to start producing early into the flowering process.
You will know the Blueberry Cupcake is ready when the white hairs (pistils) turn amber/brown and the resin glands (trichomes) look milky or cloudy, rather than clear. Cutting the plant down even a week too early can significantly reduce the potency and weight of your harvest. Patience in the flowering phase will provide the best possible outomce of Hybrid with a desired gorwth profile that will be:
Sturdy with wide internodal spacing and heavy trichome coverage.
Growers Notes: Hobby Grower's Insight
As a hobbyist, your biggest challenge with Blueberry Cupcake will be canopy management. Due to its Sativa-leaning growth habits, it can "stretch" significantly once you flip to the 12/12 light cycle. I recommend topping the plant at least twice during the vegetative stage to create a bushier structure. Also, because the buds become exceptionally dense and resinous, ensuring high-quality airflow (oscillating fans) in the final 3 weeks of flower is non-negotiable to prevent bud rot.
