Pheno B Blueberry Muffin by Zamnesia

DogDoctorOfficial Blueberry Muffin by Zamnesia | Pheno B 🍇🌱 Vegetative Week 1 | Finding Her Rhythm Hello GrowDiaries family! 👋🌱 Welcome back to the journey of Blueberry Muffin Pheno B. Last week we followed this seed through germination and into its first days above the soil. This week marks the beginning of vegetative growth as she settles into her final container and starts building the foundation that will support the entire cycle ahead. As with all plants in this project, Pheno B is being grown under a 12/12 light schedule from seed. It is a somewhat unconventional approach, but one that allows us to document how different genetics and phenotypes respond when grown under flowering photoperiods from the very beginning of life. While her sister has shown slightly faster development during these first days, Pheno B is taking things at her own pace—and that’s perfectly fine. Every plant has its own rhythm. ⸻ Moving Into The Final Container This week we transplanted Pheno B into her final home. Rather than gradually increasing pot sizes throughout the grow, we prefer to place these plants directly into their finishing containers from the beginning. The reasoning is simple. Since this project is being run under 12/12 from seed, we want root development to begin immediately without interruptions from additional transplants later in the cycle. The objective is to allow the roots to fully colonize the container while minimizing stress and maximizing consistency. At this stage, healthy roots are far more important than rapid growth above the soil. ⸻ Building Foundations With Lightmix For this run we are using Plagron Lightmix as the base substrate. Lightmix offers a gentle starting environment while still providing enough nutrition to support young plants during their first days of life. The goal during this stage is not explosive growth. The goal is balance. A healthy root zone, stable moisture levels, and a comfortable environment create the conditions needed for strong development later on. ⸻ Water First, Nutrition Second The first irrigation after transplant consisted of plain water only. Young seedlings still rely heavily on the energy reserves stored inside the seed itself, and Lightmix already contains enough nutrition to support those early stages. After several days of establishment, we introduced a very gentle feeding schedule consisting of: 🌱 Terra Grow 🌱 Pure Zym 🌱 Power Roots 🌱 Sugar Royal All products were used at light dosages with the objective of supporting root development and encouraging healthy growth without overwhelming a young seedling. At this stage patience is still one of the most valuable inputs a grower can provide. ⸻ Light Intensity & Daily Light Integral One aspect that often surprises growers when following these diaries is the light intensity being used this early. Pheno B is already receiving approximately 350 PPFD. Under a traditional vegetative schedule of 18 or more hours, this could be considered relatively strong for a seedling. However, because these plants receive only 12 hours of light each day, the total amount of light accumulated throughout the day—the Daily Light Integral (DLI)—remains significantly lower. By introducing moderate PPFD levels early, we help the plants adapt to stronger light while maintaining an appropriate daily light load. The objective is adaptation rather than acceleration. ⸻ Environmental Conditions Environmental conditions remained stable throughout the week: 🌡️ Day temperature: 27°C 🌙 Night temperature: approximately 25°C 💧 Relative humidity: 55% 🌱 Substrate temperature: 21°C 💧 Solution temperature: 21°C 🌿 CO₂: approximately 600 ppm Consistency remains one of the most important factors during seedling establishment, and so far the environment has remained exactly where we want it. ⸻ Early Observations Pheno B is already showing subtle differences compared to her sister. Growth has been slightly slower and the overall structure remains a little more compact at this stage. Leaf development is progressing well, but she appears to be taking a more measured approach to growth compared to Pheno A. This is exactly why both phenotypes are being documented separately. The differences may seem small now, but often these early observations become some of the most interesting comparisons later in the cycle. For now, she appears healthy, stable, and comfortable in her new environment. And that’s exactly what we want to see. ⸻ Looking Ahead The root system is expanding. The feeding program has begun. The environment remains stable. And now we wait. Over the next week we expect to see increased vegetative growth, larger leaves, stronger branching development, and perhaps even more clues about the unique personality of this phenotype. The race is not won during the first week. Right now we’re simply laying the foundations. And Pheno B is doing exactly that. ⸻ Thank You A huge thank you to Zamnesia for providing the Blueberry Muffin genetics for this project. Thank you to Plagron for the nutrition and substrate supporting this run. And thank you to Future of Grow, and everyone following along and sharing this journey with us. As always, thank you for stopping by. The adventure has only just begun. Grower’s Love everyone. 🌱💚🍇
