🚂 Cash Express – Pheno B Week 8 | Same Genetics, Different Expression Welcome back to another week of the 8×8 Adventure! 💚🌱 If you've been following this phenotype hunt, you've probably already noticed something fascinating about Cash Express. There are two sisters in this room. Same genetics. Same environment. Same lighting. Same irrigation system. Same nutrient solution. And yet... They are becoming two very different plants. That is exactly why I love growing multiple phenotypes side by side. Genetics don't produce copies. They produce possibilities. Cash Express Pheno B continues moving beautifully through flowering, and this week she's showing even more clearly what makes her different from her sister. She's a little taller. Her branching is different. And most importantly, her flowers are developing with a completely different structure. And I absolutely love it. 🌿 Same Genetics... Different Personality When you place Pheno A and Pheno B beside each other, the differences become much easier to appreciate. Pheno A has developed into a smaller, more compact and almost perfectly symmetrical plant. Pheno B chose a different path. She's taller, more elongated and more open through the canopy. Her flowering sites have developed along the branches in a different pattern, giving the plant a completely different visual character. Neither one is better. Neither one is worse. They're simply different expressions of the same genetic family. And this is exactly what a phenotype hunt is supposed to reveal. You can grow two plants from the same genetics, give them the same treatment from beginning to end, and still end up with two ladies that look, smell and develop differently. That's the beauty of genetics. 🌸 The White Hairs Are Taking Over Flower development has really started becoming the main event this week. The white pistils are everywhere. Every flowering site seems to be reaching outward, creating those beautiful little explosions of white hairs that make the plant look almost alive in motion. The flowers are also becoming much easier to define. We're moving beyond the stage where they simply looked like little flowering points. Now they're beginning to look like actual developing flowers. And this is where patience becomes important. There's still a lot of development ahead. The pistils are abundant, but the flowers themselves still have plenty of time to build density and volume. So while she is already looking impressive... We're nowhere near the final product yet. Two Phenotypes, Two Flower Structures This is probably one of my favourite observations this week. When I look at Pheno A and Pheno B, the difference isn't just plant height. Their flowers themselves are developing differently. Pheno B is creating a more elongated, layered structure along the branches, while Pheno A has been showing a more compact and chunky architecture. It's subtle now. But as flowering progresses, these differences should become even more pronounced. And this is one of those moments where I don't want to interfere too much. I don't want to force one phenotype to behave like the other. I want to see what Pheno B wants to become. That's the whole point. Let the genetics speak. ? Healthy, Happy and Hungry One thing is very clear when looking at this girl: She's hungry. We've increased the nutrient concentration slightly again this week. Yes, we're now running above what the basic feeding chart would normally suggest. But plants don't read feeding charts. They respond to their environment, their root systems, their metabolism and their genetic demands. And these girls have been demanding more. So we're providing more — while watching them closely. This isn't about blindly pushing nutrients higher. It's about observing the plant and responding to what she's actually showing us. And Pheno B is giving us some very good feedback. The foliage remains healthy. The flowers continue developing strongly. The plant is actively producing. And there are no obvious signs that she's unhappy with the increased concentration. So for now, we're listening. 🍃 The Leaves Tell the Story One of the things I really appreciate about this phenotype is how healthy her foliage continues to look. The leaves are deep green, well formed and beautifully structured. There's a lot of life in this plant. When you combine that healthy canopy with the amount of flowering activity we're seeing, it's difficult not to call this girl a little lush. She's simply thriving. And that's an important distinction. We're seeing plenty of flowering activity without the plant looking exhausted or unhappy. She's still carrying herself with confidence. Still producing new pistils. Still building. Still hungry. That's exactly where I want her at this stage. About Those Purple Stems... Now let's talk about something that's visible. Because if it's there, I think it's worth documenting. There is some purplish coloration appearing through portions of the stems and petioles. It's definitely present. But at this point, I'm not seeing a reason to panic about it. Why? Because the plant doesn't look distressed. The leaves look healthy. The flowering sites are developing. The pistils are coming in strongly. There's no obvious widespread deterioration accompanying the coloration. And most importantly, the plant is behaving like a happy plant. Stem and petiole coloration can have several causes, including genetics and environmental influences, so I'm not going to automatically label it as a deficiency simply because I can see purple. For now, it's something we're observing. It's part of her phenotype. If the coloration progresses together with other symptoms, then it becomes a different conversation. But right now? It's there. We're documenting it. We're watching it. And we're not going to invent a problem that the plant isn't showing us. That's an important part of reading plants. 👃 The Terpene Story Is Beginning The smell is also starting to become more interesting. At this stage, we're still relatively early in the development of the full aromatic profile. So I'm not going to pretend that we're already smelling the finished Cash Express. We're not. Right now, the overall aroma remains fairly typical for this stage of flowering, and there are still similarities across the room. But... If you spend enough time around twelve different plants every day, you start noticing little differences. And that's what I'm beginning to notice now. The plants are slowly separating themselves aromatically. Pheno A and Pheno B currently seem to share a similar general terpene direction. They're not identical, but there is a recognizable family resemblance. And I'm very curious to see whether that similarity remains as the flowers mature. Because sometimes the differences become much more obvious later in flowering. For now, I'm simply enjoying the first hints. 💡 Above and Below The combination of the overhead Future of Grow Black Series LED and the LumiFlora under-canopy lighting continues giving this girl plenty of light throughout her structure. Her naturally more open architecture works beautifully with this setup. The flowers aren't packed into one giant wall of foliage. There's space between the branches. There's airflow. There's light penetration. And the lower flowering sites aren't completely forgotten. It's another interesting contrast with Pheno A, whose more compact structure creates a very different light distribution. Same room. Same lights. Different architecture. And once again, the plant itself changes the equation. 🌡️ Environment The room continues providing a remarkably consistent environment for all twelve phenotypes. 🌡️ Day temperature: 29°C 🌙 Night temperature: 25°C 💧 Relative humidity: 60% 🥥 Root zone temperature: 21°C 💦 Nutrient solution temperature: 24°C ⚗️ pH: 6.0 ⚡ EC: approximately 2.0 mS/cm 💨 CO₂: 639 ppm 💡 Light schedule: 12/12 ? Pot size: 15 L 💧 Water consumption: approximately 1.3 L/24h Once again, consistency remains one of the biggest advantages of this experiment. With twelve different cultivars sharing the same environment, the plants themselves become the variables we're watching. And Cash Express Pheno B is definitely writing her own chapter. 🌱 Feeding This week we made another small increase to the nutrient concentration. The current reservoir is running: Plagron Terra Bloom – 2.2 ml/L Plagron Power Buds – 1 ml/L Plagron Green Sensation – 1 ml/L Plagron Sugar Royal – 1 ml/L pH adjustment with Lemon Kick / pH Plus as required. The important part here isn't simply the numbers. It's the response. These girls are demanding. They're actively flowering, they're consuming, and they're telling us that they're capable of using more. So we're providing it. But we're also watching. No blind chasing of numbers. No feeding harder simply because we can. Observe → respond → observe again. That's the philosophy. 📸 Behind the Lens This phenotype is becoming a photographer's dream. The photographs this week really show the differences between the sisters. Her flowers have their own architecture. Her leaves frame the flowers differently. Her taller structure creates different perspectives throughout the plant. And those white pistils... They're absolutely everywhere. Some of the close-ups almost look like little fireworks exploding from the tops of the flowers. The resin coverage is also becoming increasingly visible on the sugar leaves, giving us those beautiful sparkling edges that become so addictive to photograph. And I have to say... This girl is beautiful. Not because she's the biggest. Not because she's the fastest. Not because she's trying to dominate the room. She's beautiful because she's becoming exactly what she is supposed to become. 🔍 Quick Recap So where are we now? 🚂 Cash Express Pheno B is thriving. 🌿 She's taller and more open than her sister. 🌸 Flower formation is clearly different from Pheno A. ? White pistils are multiplying rapidly across the canopy. 🍃 Foliage remains healthy and vigorous. The phenotype is becoming increasingly recognizable. 👃 The terpene profile is beginning to show itself, although it's still early. 💜 Some purple coloration is visible in stems and petioles, but currently without accompanying signs of significant plant stress. 🌱 She's hungry, so we've increased nutrition slightly again. And most importantly... She's happy. 🔮 What I Expect Next Week Next week, I expect the flowers to become more substantial. The pistils will probably continue appearing in large numbers, while the actual flower mass slowly catches up with all that beautiful white hair. I expect the structure of Pheno B to become even easier to distinguish from Pheno A. The terpene profile may also start becoming more interesting as the flowers mature. And I'm especially curious about the purple coloration. Not because I'm worried about it... But because I want to see whether it remains part of her natural expression or becomes more pronounced as flowering progresses. What I DON'T expect: I don't expect these flowers to suddenly look finished. I don't expect the final terpene profile to be completely obvious yet. And I certainly don't expect Pheno B to suddenly start looking like her sister. She's already told us that's not who she is. And I wouldn't want it any other way. 🌱 The Beauty of a Phenotype Hunt This is probably the biggest lesson this week. When you're growing twelve different cultivars together, it's very easy to look at differences and immediately ask: "Which one is better?" But that's not really the right question. The better question is: "What makes this one different?" Pheno A has her own personality. Pheno B has hers. And both are fascinating. The goal isn't to make them identical. The goal is to discover what each one carries within its genetics. That's what makes this 8×8 Adventure so much fun. We're not just growing plants. We're watching twelve different genetic stories unfold under the same conditions. And Cash Express Pheno B is writing a particularly beautiful chapter right now. 💚 Thank You As always, thank you so much to everyone following this 8×8 Adventure. A huge thank you to GrowDiaries for creating a place where growers from around the world can document, compare, learn and share these journeys together. Thank you to Zamnesia for these Cash Express genetics and for giving us the opportunity to explore how differently these phenotypes can express themselves. Thank you to Plagron for providing the nutrition supporting this entire journey. Thank you to Future of Grow LED for the powerful overhead lighting driving the plants throughout the cycle. A special thank you to LumiFlora for the under-canopy lighting helping bring additional light to those lower flowering sites. And thank you to AutoPot for the irrigation system that continues allowing the plants to manage their own water demand. And finally... Thank you to every single person following along. Every comment. Every message. Every question. Every person who simply stops for a moment to look at these plants. It means a lot. This project is about more than chasing numbers or comparing yields. It's about watching nature express itself. And this week, Cash Express Pheno B is reminding us once again that same genetics doesn't mean same plant. She's taller than her sister. She's built differently. She's flowering differently. She's beginning to reveal her own aromatic personality. And she's absolutely beautiful doing it. Growers Love, and I'll see you all next week as Cash Express Pheno B continues writing her own story in the 8×8 Adventure. 💚🚂🌱 PS- we did defoliate a few leafs here and there
