Launched in 2024, Blueberry Bubblegum Automatic was thoughtfully crafted for Sensi Seeds Research through a backcross of Sunset Sherbert with Gelato #420, enhancing its unique traits. This strain amplifies Gelato #420’s aroma, yields, and euphoric effects, complemented by the stability and relaxation of Sunset Sherbet.
We chose BAC Lava Mix as our substrate during this cultivation cycle and utilised 1000W Green Power Phillips lights for optimal growth conditions. As the plants progress through their development, varying humidity levels become necessary. However, we maintained a humidity level of 65% during the initial stages with seedlings. Daytime temperatures were kept at 23°C, and nighttime temperatures dropped to 21°C.
Autoflowers are not influenced by changes in lighting, and theoretically, you can maintain them under an 18/6 schedule throughout their growth. However, since we were cultivating them alongside other cultivars, transitioning to a 12/12 lighting schedule can aid in their maturation and production with reduced stress.
During the vegetative phase, we employed Bio Grow and maintained a lighting schedule of 18 hours on and 6 hours off. As we transitioned to the flowering stage, we adjusted our nutrient approach by introducing Bio Bloom to meet the specific requirements. Simultaneously, we modified our lighting schedule to 12 hours on and 12 hours off.
We initiated germination by situating our Blueberry Bubblegum seed within a pre-moistened rock wool cube positioned 80 cm below a 600W Green Power Phillips light. After 72 hours, the sprout had successfully emerged. On the third day, we introduced 100 ml of water around the stem. Throughout this phase, we maintained a pH level of 6 for the plants, and the electrical conductivity (EC) commenced at 0.8.
As the roots began to emerge from the bottom of the rock wool cube, we transplanted our seedlings into a 1L pot. Creating a small pocket beneath the soil line, we nestled the cube and covered it with soil. To enhance root growth, we also supplemented a rooting hormone, our tiny seedling was beginning to reach upward for the light, with the first set of leaves just visible. By the end of the week, our seedling had reached 6 cm.
Throughout week two, we moved the new plants under their long-term light – the 1000W Green Power Phillips. Our Blueberry Bubblegum continued growing, with the stem reaching 16 cm. The increased developments led to increased water consumption, so we upped our small amount of water to 200 ml and raised our EC to 1.4. At the end of the week, we moved the plant into an 8L pot so that the root system could continue to expand.
In the third week, as we gained confidence in the well-established root zone, we adjusted our watering intake to 400 ml and modified our watering technique to cover a wider radius around the stem. All other environmental conditions remained unchanged. The plant exhibited robust growth, revealing multiple visible bud sites and broad fan leaves strategically maximising light absorption. As the plant reached this advanced stage, By the week’s end, the plant had attained a height of 32 cm.
Our Blueberry Bubblegum thrived throughout the fourth week, becoming more luxuriant each day. The unique trait of these Feminized Autoflowers is their ability to induce flowering independently. Transitioning to the traditional flowering phase, we adjusted to a 12/12 lighting cycle, introduced Bio Bloom, and raised the water volume to 800 ml with an EC of 1.7. The plants displayed an impressive appearance, with robust development, heightened aroma, and early stigma development.
As part of our Integrated Pest Management strategy, we introduced Neoseiulus californicus and Amblyseius swirskii to proactively ward off spider mites and other potential pests in the fifth week. These resilient predator mites, when consistently applied, prove highly effective in maintaining a pest-free environment for your plants. The plant’s structure was noticeably robust, prompting us to enhance our watering routine with 1000 ml of diluted fertiliser. As the week concluded, our plant reached 60 cm.
In week six, we upped our water volume to 1500 ml, and the lush green colour of the plant provided reassurance that it was receiving the appropriate nutrient ratios. The rapid growth slowed a little with biochemical processes in the plant shifting from vegetative to reproductive. The height by the end of the sixth week was 68 cm. Some of the “stretch” between the nodes we expected is visible, but overall, the plant was filled out this week.
Week seven was another solid week of development. We are delighted with the plant’s health and have dropped our humidity levels to 60% to avoid potential mould issues. Still watering with diluted nutrients, we gave the plants 1500 ml at pH 6 and EC 1.8. A slight aroma is evident in the growing area, and the bud sites continue to develop with a long, bright stigma covering the flowers. We saw more growth now, and the plant reached 84 cm.
By the conclusion of week eight, our Blueberry Bubblegum stood at an impressive height of 93 cm, highlighting its robust growth and well-established stature. The plant displayed a sturdy apical main stem, broad fan leaves, and increasing trichome development, showcasing the intricate details of its maturation process.
In week nine, we performed a gentle defoliation, removing older fan leaves obstructing light for the maturing buds. Given the rapid lifecycle of autoflowers and their limited recovery time from pruning stress, we kept this process to a minimum. During this time, the plant extended another 12 cm, reaching a height of 105 cm. The aroma intensified daily, and a multitude of trichomes became visible on the developing buds.
By the conclusion of week ten, the plant had attained a height of 117 cm. The majority of the buds were fully developed, requiring only further ripening. As a result, some ancillary shoots began to bear the weight of the buds. While there was the option for training to support them if they seemed at risk of breaking, the plant demonstrated resilience—bending without breaking. In the final weeks, we flushed our medium to eliminate any residual salts that might affect the overall flavour of the cured buds.
In week eleven, we closely monitored the trichome colouration and density. Throughout these weeks, we focused on identifying the characteristic cloudy colour that signals the flower’s peak maturity. While some trichomes were transitioning to a more clouded and less clear state, our target was to observe a ratio of 70% cloudy trichome heads with 30% amber for optimal harvesting conditions. To complement the increased biomass, we reduced humidity to 56%.
Blueberry Bubblegum showcased sizable flowers adorned with sticky resin, creating a dense and compact appearance. Amidst the flowering stage, vibrant orange pistils and hints of purple hues emerged, adding a visually striking contrast among the abundance of trichomes.
After closely monitoring the trichomes and confirming they met our specific criteria, we decided to wrap things up with our Blueberry Bubblegum, which had reached a final height of 120 cm. This decision resulted from a detailed and careful approach, considering both the optimal timing and the ideal height for the harvest. As we reached the end of week twelve, we delicately cut down the plants, ensuring they were harvested at the peak of their maturity.
Upon achieving the recommended trichome ratios, we harvested the entire plant by cutting it down at the base of the stem. Following this, we meticulously removed all the large fan leaves, hanging the plant upside down in a dark environment for a meticulous 21-day drying period.
During this time, we regularly inspected the plant, testing the branches for dryness by snapping when bent. Once content with the dryness level, the entire plant was carefully broken down into larger branches to facilitate trimming. We meticulously trimmed the dried buds, removing excess foliage to enhance the curing process and ensure optimal quality.
The buds were carefully placed in glass jars, kickstarting the essential curing process. To remove excess moisture, we left the lids open on the first day. Following this, we sealed the jars, and a meticulous burping routine was adopted, allowing air to escape for approximately one to two hours, 2 to 3 times daily, for one week.
Subsequently, for four weeks, the jars were opened once daily. To enhance the curing process, the buds were then transferred to a Cvault container for an extended 2-month period, maintaining a consistent 62% humidity level.
Blueberry Bubblegum began emitting pungent floral notes in the final weeks of flowering. However, post-curing, the aroma transformed into a sweet profile, embodying the essence of its “blueberry bubblegum” namesake, complemented by an underlying pungent scent with subtle hints of pine.
Its distinctive terpene profile showcases rich citrus notes complemented by herbal and peppery tones. Additionally, a subtle hint of diesel fuel adds depth to the overall aromatic experience.
Upon loading our vaporizer, distinct flavours of citrus, herbs, fuel, and pepper unfold in this strain, accompanied by a notable grassy undertone. Blueberry Bubblegum offers a calming and uplifting high, delivering a comprehensive full-body buzz. Its effects seamlessly blend complete relaxation for the body with a stimulated and inspired mental state. With a tested THC content of 24.6% we’re very proud of this grow.
