? Black Diamond – Plant B Week 3 | Vegetation 8×8 Adventure – 12/12 From Seed Another exciting week in the 8×8 Adventure! Every plant in this project is being grown using the 12/12 From Seed technique, allowing each phenotype to express its natural structure while remaining compact and efficient. Plant B of Black Diamond is beginning to reveal its own personality, showing strong apical dominance, excellent vigor, and beautiful structural symmetry. The goal of this project continues to be documenting every phenotype individually, following its complete journey from seed to harvest while using the Plagron nutrient line throughout the entire grow. ⸻ 🌱 Grow Conditions • Week: 3 (Vegetation) • Height: 17 cm • Light Schedule: 12/12 • Day Temperature: 27°C • Night Temperature: 25°C • Relative Humidity: 55% • CO₂: 666 ppm • pH: 6.0 • EC: 1.3 • Solution Temperature: 20°C • Root Zone Temperature: 21°C • Pot Size: 15 L • Daily Water: 1 L Feeding * Terra Grow – 1.8 ml/L * Power Roots – 1 ml/L * Pure Zym – 1 ml/L * Sugar Royal – 1 ml/L * pH Plus / Lemon Kick as required ⸻ 🌿 Weekly Development Plant B continues to impress with its vigorous and balanced development. During this third week, vertical growth accelerated while maintaining short internodal spacing, creating a compact but well-structured plant that looks perfectly suited for the 12/12 method. The main stem has thickened noticeably and is already showing excellent strength. Side branches are emerging evenly from every node, indicating that this phenotype should build a very uniform flowering structure over the coming weeks. The newest growth is vibrant lime green, gradually darkening as the leaves mature, while the larger fan leaves remain a rich healthy green with no visible signs of nutrient stress or deficiencies. ⸻ 👀 Structural Observations One characteristic that immediately stands out on Plant B is its strong central leader. Unlike some phenotypes that naturally spread laterally early on, this individual seems determined to build a dominant main cola while simultaneously producing vigorous secondary branches. Node spacing remains pleasantly tight, giving the plant a compact architecture without becoming overcrowded. As more side shoots develop, the canopy is beginning to fill naturally while maintaining excellent airflow through the interior. Stem diameter has increased considerably compared to last week, suggesting the root system is becoming well established inside the 15-liter container. ⸻ 🍃 Plant Health Health this week has been excellent. The leaves remain flat, fully expanded and symmetrical, with strong petioles supporting each fan leaf. New shoots are developing quickly from every node and there are no signs of nutrient burn, deficiencies or environmental stress. The feeding schedule appears to be matching the plant’s demand very well, supporting vigorous growth while keeping the foliage clean and healthy. ⸻ 📸 Photo Notes This week’s photographs clearly highlight the symmetrical canopy developing from above, while the side profile showcases the increasing stem thickness and vigorous branching beginning at every internode. Close-up images of the growth tip reveal rapid vegetative expansion and healthy leaf formation, confirming that Plant B is transitioning smoothly toward the next stage of development. ⸻ 🔜 Looking Ahead With the root system now well established and the structural framework taking shape, the coming week should bring a noticeable increase in both vertical growth and lateral branch development. As flowering approaches under the continuous 12/12 schedule, it will be fascinating to see how Black Diamond Plant B balances stretch with bud site formation. Based on its current architecture, this phenotype has the potential to produce a well-organized canopy with multiple productive flowering sites. Growers Love and see you all ext week 🙏
