Folder 10 – Frosted Guava Auto B Week 4 | Vegetation – The Quiet Climber Welcome back to The 8×8 Adventure, a project where twelve unique cultivars are being grown side by side inside the same environment, allowing every genetic to express its own personality under identical conditions. Each plant is documented individually because no two phenotypes tell the same story. Even when they share the same genetics, subtle differences in structure, vigor and flowering behaviour make every diary unique. Frosted Guava Auto B is proving exactly that. Although she shares the tent with her sister, she has developed her own character. Slightly taller, equally healthy, and every bit as determined, she’s entering the next chapter of her life with confidence. Our 12/12-from-seed journey continues, and this week marks another exciting milestone as the first signs of flowering begin to appear. ⸻ 🌱 Week 4 – A Compact Plant With Her Own Personality While Plant B has stretched just a little more than her sister, she remains a very compact autoflower compared to many of the other cultivars sharing this 8×8 room. Instead of investing her energy into vertical growth, she has focused on producing tight internodal spacing, sturdy branches and a surprisingly balanced structure. Looking around the room, it’s already clear that Frosted Guava is unlikely to become one of the tallest ladies of the garden—but height has never been the goal. Sometimes the smallest plants surprise us with the biggest harvests. Her canopy is filling beautifully, each node producing healthy new growth that will soon become flowering sites. Every day she looks more organized, more symmetrical and more prepared for what comes next. ⸻ 🌿 Gentle Training, Natural Development Just like her sister, Plant B has only received gentle Low Stress Training throughout her early life. Rather than forcing the plant into shape, I’ve focused on carefully bending large fan leaves, tucking foliage away from developing shoots and allowing natural light penetration into the centre of the canopy. This subtle approach has encouraged multiple branches to grow evenly without creating unnecessary stress. The result is a plant that still looks completely natural while developing a much more open canopy. Sometimes patience is the best training technique. ⸻ 🌸 Pre-Flower Has Officially Begun This week brings one of my favourite moments of every grow. Tiny white pistils have started appearing throughout the upper nodes, confirming that Frosted Guava Auto B has officially entered the pre-flowering stage. One of the most fascinating aspects of this 12/12-from-seed experiment is watching these autoflowers transition into bloom without hesitation. Rather than waiting for a long vegetative period, they simply follow their own internal clock. Despite her compact size, she’s wasting no time. The foundation has been built, and now the real show is about to begin. Over the coming weeks, I’ll be watching closely to see whether she delivers a modest stretch or stays true to her compact structure while focusing her energy on dense flower production. Either way, she’s looking incredibly promising. ⸻ 🌡️ Environmental Conditions The room continues to provide a stable environment for all twelve cultivars despite the warmer summer temperatures. Environment • 🌡️ Day Temperature: 33°C • 🌙 Night Temperature: 25°C • 💧 Relative Humidity: 63% • ? Substrate Temperature: 21°C • 💦 Nutrient Solution Temperature: 26°C • ⚗️ pH: 6.1 • ⚡ EC: 1.35 mS/cm • ☁️ CO₂: 639 ppm • 💧 Water Consumption: 1.1 litres per plant per day Even with daytime temperatures reaching 33°C, Plant B continues showing excellent colour, strong leaf posture and vigorous growth, demonstrating how well she’s adapting to the environment. ⸻ Feeding Schedule This week’s feeding remained simple and consistent, allowing the plant to continue building healthy vegetative growth before fully committing to flowering. Per litre • Terra Grow — 1.8 ml • Power Roots — 1 ml • Pure Zym — 1 ml • Sugar Royal — 1 ml Adjusted using: • pH Plus — 0.03 ml • Lemon Kick — 0.03 ml The Plagron feeding programme continues delivering exactly what these plants need at this stage—healthy roots, lush green foliage and vigorous, stress-free development. ⸻ 💡 Lighting The entire 8×8 garden continues to thrive beneath the outstanding Future of Grow LED fixtures. Uniform light distribution across the canopy has helped every cultivar develop evenly, while allowing each phenotype to express its own natural growth pattern. It’s fascinating walking through the room and seeing twelve completely different personalities growing under exactly the same environmental conditions. Frosted Guava Auto B is a perfect example of how genetics shape the plant just as much as the environment. ⸻ 🌱 Looking Ahead Week four closes with Plant B looking healthy, balanced and full of potential. She’s entering flower with strong branching, vibrant foliage and a structure that promises excellent light penetration throughout the canopy. While some cultivars in the room are already showing more vertical ambition, Frosted Guava B seems determined to stay compact and focus her energy where it matters most. The coming weeks will reveal whether this translates into dense, resin-packed flowers—but for now, she’s ticking every box. The journey is only getting started. ⸻ 🙏 Thank You As always, thank you to everyone following The 8×8 Adventure. Sharing this project with growers from around the world is one of the most rewarding parts of the journey, and I truly appreciate every comment, question and piece of advice along the way. A special thank you to Zamnesia for providing these exciting Frosted Guava Auto genetics, to Plagron for the trusted substrates and nutrient line that continue supporting healthy, vigorous growth, and to Future of Grow LED for delivering exceptional lighting that allows every phenotype in this room to perform at its very best. Finally, thank you to GrowDiaries for giving this amazing community a place to learn, share experiences and celebrate our passion for growing together. See you all next week, when Frosted Guava Auto B takes another step into flowering. Until then… Growers Love and happy growing! 🌱💚
