Hello GrowDiaries family! đđ±
Welcome to another new journey, and this time we're following Blueberry Muffin by Zamnesia â Pheno B.
Before we begin, I'd like to mention a small change in the way I'll be documenting this run. Due to the current photo limitations on GrowDiaries, I've decided to separate each phenotype into its own dedicated diary. Instead of documenting multiple plants within a single journal, each phenotype will now have its own space from seed to harvest.
This approach allows me to continue documenting every stage as thoroughly as possible while selecting the best photos from each week. The goal remains exactly the same as always: to create a complete educational record of the grow, sharing not only the successes, but also the challenges, observations, and lessons learned along the way.
For those following my previous diaries, you'll already know that this cultivation style is a little different from what many growers choose. Over the years it has become part of my own growing philosophy, and throughout this journey I'll do my best to explain not only what I'm doing, but also why I'm doing it.
So let's begin at the very beginning: germination.
For this run, all genetics are provided by Zamnesia Seeds, while the substrate and nutrient line come from Plagron. Blueberry Muffin has built quite a reputation among growers for its beautiful structure, vibrant colors, and unmistakable aroma profile, making it a cultivar I've been looking forward to documenting from seed to harvest.
To start the seeds, I used the Cannakan germination system. For those unfamiliar with it, it is a simple but practical germination container that allows multiple seeds or cultivars to be organized separately while maintaining a stable environment. Each compartment can be individually labeled, making it easy to keep track of genetics throughout the germination process.
The seeds were placed in plain water inside the Cannakan and left to hydrate. Within roughly 24 hours, healthy taproots had already emerged and the seeds were ready for the next stage.
This run also marks my first experience using coco starter plugs. The plugs were thoroughly hydrated, lightly squeezed to remove excess water, and the germinated seeds were carefully placed inside. They then spent approximately 24 hours inside a propagation dome where humidity remained high enough to support early development.
The response was immediate. Before the first full day had passed, the seedlings were already emerging, opening, and searching for light. At that point I decided to transplant them directly into small containers filled with Plagron Lightmix.
At this stage, the only thing they receive is water.
Seeds already contain everything required to support their initial development, so I prefer not to introduce nutrients during germination. The objective is simply to provide moisture, oxygen, warmth, and a stable environment while allowing the seedling to establish itself naturally.
Environmental conditions were kept intentionally simple. Temperatures remained around 26â27°C, while humidity stayed between 65â70% thanks to the Spider Farmer humidifier. While many growers prefer keeping seedlings inside a dome for extended periods, I personally like introducing them to the ambient environment early. A method that may differ from more traditional approaches, but one that has become part of my own cultivation style over time.
Airflow was kept extremely gentle during these first days. Seedlings need fresh air, but excessive airflow can quickly become counterproductive. At this stage, less is often more.
For bottom heat, a propagation mat was used and maintained around 40°C. The reason for this is simple: heat sources generally need to operate slightly above the target root-zone temperature in order to compensate for environmental losses and maintain consistent warmth where it's actually needed.
Lighting during germination was intentionally soft. The goal is not explosive growth but healthy establishment. Once these young plants are fully settled, they will be moved under the Future of Grow Black Series 600W full-spectrum LED, which will carry them through the rest of the cycle.
Like all plants in this project, this phenotype will be grown under a 12/12 light schedule from seed to harvest. It's a method I've documented for years and one I'll continue exploring throughout this diary. Every observation, success, challenge, and lesson learned will be documented as honestly as possible.
For now, everything is looking healthy, the seedlings have emerged successfully, and the journey of Blueberry Muffin Pheno B is officially underway.
Thank you to Zamnesia for the genetics and to Plagron for the substrate and nutrition supporting this run.
As always, thank you to everyone following along. I hope you'll enjoy the journey as much as I do documenting it.
Grower's Love! đ±đ
