Black Diamond Auto — Pheno B 🌱💎 Week 1 Vegetation | Another Plant That Refuses to Wait Hello GrowDiaries family! 👋🌱 Welcome back to the second phenotype of Black Diamond Auto. After documenting Pheno A, I was curious to see whether her sister would follow a similar path or begin revealing a completely different personality. By the end of Week 1, the answer was becoming quite clear. While every plant develops at its own pace, this girl appears just as eager to get moving as her sister. In fact, looking through the week’s progression, Black Diamond Auto Pheno B showed some of the fastest early development in the entire garden. And for a plant growing under a 12/12-from-seed schedule, that’s always fun to watch. ⸻ The Start of the Journey Like the rest of this project, this phenotype was transplanted directly into her final container from the very beginning. The objective remains simple: Allow the root system to establish itself without requiring additional transplants later in life. By minimizing root disturbance during the earliest stages, the plant can focus entirely on growth and development rather than recovering from unnecessary stress. As always, the substrate used was Plagron Lightmix, chosen for its gentle nutrient charge and excellent structure for young plants. ⸻ Environmental Conditions Environmental conditions remained identical to the rest of the garden: 🌡️ Day temperature: 27°C 🌙 Night temperature: 25°C 💧 Relative humidity: 55% ⚡ Light schedule: 12/12 from seed 💨 Gentle airflow 🌱 Plagron nutrient program 💡 Future Of Grow Black Series LED lighting The objective remains creating a stable environment where genetics can express themselves naturally without environmental stress influencing development. ⸻ Early Development From the first photographs onward, Pheno B displayed excellent vigor. The seedling emerged cleanly, established itself quickly, and immediately began building leaf surface. Throughout the week, growth remained steady and consistent. Internodal spacing stayed compact. Leaf color remained healthy. Stem development looked strong. And perhaps most noticeably, this plant wasted very little time transitioning from seedling growth into active vegetative development. Every new set of photographs showed visible progress. ⸻ A Plant in a Hurry One of the most interesting observations this week was the speed at which new growth appeared. Just like her sister, this phenotype seems determined to move quickly. By the end of the week, the plant had already developed impressively large leaves relative to its age. Looking at the overhead photographs, the structure is beginning to spread outward while simultaneously pushing new growth from the center. The overall appearance is vigorous, energetic, and highly efficient. For a plant only one week into vegetation, she already looks eager to start building her future canopy. ⸻ Comparing the Two Phenotypes Although both Black Diamond phenotypes appear vigorous, subtle differences are already becoming visible. Pheno A showed slightly more unusual early leaf development before rapidly accelerating. Pheno B appears a little more symmetrical and organized in her structure while maintaining the same impressive pace of growth. At this stage, both phenotypes are performing extremely well. Whether these small differences remain or disappear over time is something we’ll continue monitoring throughout the run. ⸻ Why Autos Often Move Faster One interesting observation throughout this project has been the difference between some of the autoflowers and the photoperiod cultivars. Several of the autos, including this Black Diamond phenotype, appear to be developing slightly faster during these earliest stages. This isn’t unusual. Autoflowers have evolved with a relatively short life cycle and often prioritize rapid early establishment. Because they do not depend on a photoperiod change to begin flowering, many autos spend very little time deciding what to do. They simply start growing. And this phenotype seems determined to prove that point. ⸻ First Impressions So far, Black Diamond Auto Pheno B has been a pleasure to watch. Healthy color. Strong structure. Excellent vigor. Large leaf development for her age. And a growth rate that places her among the most energetic young plants in the room. At only one week into vegetation, she’s already showing the kind of momentum that makes future updates exciting. ⸻ Looking Ahead The first week has provided a strong foundation. Now the real fun begins. Over the coming weeks we’ll continue following both Black Diamond phenotypes as they develop under the 12/12-from-seed project, documenting structure, growth patterns, and any unique characteristics they choose to reveal. For now, Pheno B appears to have one message: “No time to waste.” Huge thanks to Zamnesia Seeds for the genetics, Plagron for the substrate and nutrition, Future Of Grow for the lighting, and everyone following along on another seed-to-harvest adventure. Grower’s Love everyone. 🌱💚
