💙 PROJECT BLUE TENT – WEEK 15 💙 🥒 PICKLE LEMON HAZE F1 – PHENO A 🍂 THE COLOURS ARE CHANGING, THE FLOWERS ARE GETTING READY, AND WE'RE ENJOYING THE FINAL CHAPTERS! Hello everyone, and welcome back to another chapter of Project Blue Tent! 💙🌱 My friends, my friends… IS IT SPRING OUTSIDE OR ARE WE STILL IN AUTUMN?! 😂🌸 The temperatures outside are rising again, the plants are showing beautiful colour transitions, and inside our little green oasis, we're approaching what I believe will be the final chapter of this adventure. Welcome to Week 15 of flowering for Pickle Lemon Haze F1 Pheno A! And what a beautiful girl she is! This week is very much about observation. We're not introducing new training techniques, we're not restructuring the canopy, and we're not making unnecessary changes to an environment that's already established. The major work is behind us. The flowers are looking beautiful, the fading is becoming increasingly visible, and we're observing how each individual plant progresses towards maturity. We've also moved to plain water, with our reservoir EC now sitting around 0.2 mS/cm and the natural pH reading approximately 5.98. Meanwhile, our under-canopy lighting experiment continues to give us interesting observations, particularly regarding the colour expression and the development of the flowers throughout the lower sections of the canopy. And because apparently taking photographs of flowers wasn't enough for this week's entertainment, we've also invited Matilda, our little spider friend, for another photographic adventure! 😂🕷️ We're also continuing our 3D-printing experiments, testing some new irrigation accessories for the next run. So, although this is a week without major cultivation changes, there's still plenty to talk about. Let's give Pickle Lemon Haze F1 Pheno A her own spotlight! 💙🌿 🌱 A QUICK LOOK BACK – WHAT IS PROJECT BLUE TENT? For anyone joining us for the first time, let's quickly explain what we're doing here. Project Blue Tent is our shared growing environment, where we're documenting four individual plants representing two different Zamnesia F1 cultivars. 🌈 BLUE WAFFLE F1 – PHENO A. 🌈 BLUE WAFFLE F1 – PHENO B. 🥒 PICKLE LEMON HAZE F1 – PHENO A. 🥒 PICKLE LEMON HAZE F1 – PHENO B. Four individual plants. Two cultivars. One shared ecosystem. All four girls share the same general environmental conditions, reservoir, irrigation arrangement, and nutritional program. Throughout the project, we've documented their development individually, starting with their early stages and following them through transplantation, HST, topping, LST, SCROG, defoliation, and flowering. We've spent considerable time establishing the canopy, organizing the branches, supporting the structure, and experimenting with different aspects of our growing environment. Lighting has also been an important part of this project. Our main overhead LEDs provide the primary illumination, while two LumiFlora 150W full-spectrum fixtures have been installed beneath the canopy in an X-cross configuration. Nutritionally, we've been working with the PLAGRON Hydro line, gradually adjusting the program as the plants progressed through flowering. And now, we're approaching the finish. The structural work has been completed, the flowers have developed throughout the canopy, and we're concentrating on observing the individual characteristics of each plant. That's also why we've kept separate GrowDiaries reports. Even when plants share the same environment, their individual expressions deserve to be documented independently. And today, it's Pickle Lemon Haze F1 Pheno A's turn! 💙🥒 🌸 WEEK 15 – PHENO A IS LOOKING BEAUTIFUL! Let's start with the obvious. THIS GIRL IS LOOKING FANTASTIC! 😂💙 Pickle Lemon Haze F1 Pheno A continues to impress with her flower density, compact structure, and beautiful overall appearance. We're now at a stage where the flowers themselves are taking centre stage. The earlier work on the canopy is behind us, and we're able to appreciate the structure that developed throughout the previous weeks. The branches are established, the flowering sites are distributed throughout the canopy, and the flowers are continuing to show their individual characteristics. One of the things I particularly enjoy about this stage is being able to step back and appreciate the complete plant. You spend weeks working on structure, positioning branches, managing the canopy, and making adjustments. Eventually, you reach a point where you can simply grab the camera and enjoy what has developed. And that's exactly where we are. There aren't any major structural interventions this week. We're concentrating on observation, photography, environmental stability, and the individual progression of the plants. Sometimes, doing nothing is precisely what the situation calls for. And honestly, I could spend hours looking at these girls! 😂📸🌱 🍂 THE FADING – BEAUTIFUL COLOUR TRANSITIONS THROUGHOUT THE PLANT! Now, let's talk about one of the most interesting things happening this week. THE FADING! We're seeing increasingly noticeable colour changes throughout Pheno A, with lighter green areas, yellowing foliage, and warmer reddish tones becoming more visible. And I absolutely love photographing this stage. But why does this happen? Let's take a moment to understand what's happening rather than simply describing the colours. The green appearance of leaves is primarily associated with chlorophyll, the pigment responsible for capturing light energy during photosynthesis. As plants progress through their life cycle, chlorophyll levels can decline, allowing other pigments to become more visible. Carotenoids contribute yellow and orange tones, while anthocyanins are responsible for many of the red, purple, and blue colours we can observe in plants. The expression of these pigments is influenced by genetics, while environmental conditions can also affect how the colours develop. This is particularly interesting in Project Blue Tent because we're observing several plants sharing the same general environment. Even within the same cultivar, individual phenotypes can display different colour combinations. And between our two cultivars, the contrast can be even more noticeable. Pheno A is showing us her own beautiful colour palette, with increasingly visible fading and warmer tones throughout the plant. Her sister, Pheno B, has been displaying a somewhat different expression. And that's exactly what makes individual phenotype documentation so interesting. We shouldn't assume that every plant will develop identical colours simply because they share the same environment. Nor should we attribute every change to one single factor. We're recording what we observe and looking at the complete picture. The flower development, the trichomes, the pistils, the foliage, and the overall condition of the plant all matter. One important point: fading alone doesn't tell us that a plant is ready for harvest. It's one observation among several, and we're continuing to assess the individual maturity of the flowers. For now, we're enjoying the colours and documenting the changes. 🍂🌈💙 ❄️ THE FLOWERS – DENSE, COMPACT, AND BEAUTIFULLY DEVELOPED! Now, let's get closer! The flowers are looking absolutely beautiful. Their compact appearance and dense structure are among the things that stand out most when looking at Pheno A. Throughout the canopy, we're finding plenty of beautiful flowering sites, and the photographs give us an opportunity to appreciate their development from different angles. Looking at the whole plant, we can appreciate the overall structure and the distribution of the flowers. But when we move closer, we discover an entirely different world. The textures. The pistils. The trichomes. The intricate details of the flowers and surrounding sugar leaves. And that's precisely why I enjoy macro photography so much. A photograph can capture a beautiful moment, but getting closer allows us to appreciate details that might otherwise go unnoticed. The visible frost is another beautiful feature of this stage. And although we're approaching the end, we're not going to rush the conclusion. We'll continue observing the trichomes and the overall flower maturity before making any final decisions. For now, we're enjoying the view, taking photographs, and appreciating the beautiful work these girls have done! 😂📸❄️ 🌈 PHENOTYPIC EXPRESSION – SAME CULTIVAR DOESN'T MEAN IDENTICAL PLANTS! This is something I always enjoy discussing when documenting individual plants. We have two Pickle Lemon Haze F1 sisters growing inside the same tent. They share the same general environment, lighting arrangement, irrigation system, and nutritional program. Yet individual plants can still express their characteristics differently. Their morphology, flower formation, pigmentation, and progression through flowering can all provide interesting differences to observe. Genetics influence how a plant expresses its characteristics, while environmental factors can also contribute to the appearance we see. This is why comparing individual phenotypes is so interesting. We can look at Pheno A and Pheno B and appreciate their similarities without expecting them to be identical. And the same applies when comparing the Pickle Lemon Haze girls with our Blue Waffle F1 plants. Four individual plants, sharing one ecosystem, but each with her own story. We're not trying to manufacture differences or attribute every characteristic to a specific cause. We're documenting what we actually observe. And that's one of the most valuable aspects of keeping individual diaries. 💙🌿 👃 THE AROMA – THE ROOM IS GETTING INCREDIBLY AROMATIC! Now, let's talk about something our photographs cannot communicate. THE SMELL! 😂🌸 The aroma throughout the room is incredibly strong, and spending time around these plants has become an absolute pleasure. It's one of those things that makes the final weeks particularly enjoyable. We can photograph the flowers. We can capture the colours. We can get close enough to document the trichomes. But the aroma is something you'll have to experience yourself! The photographs simply cannot do that part justice. I'm not going to invent a detailed terpene profile or assign specific aromatic compounds without proper testing. What I can tell you is that the room smells beautiful, and Pheno A is certainly contributing to that wonderful aromatic experience. A little reminder of why we enjoy documenting every stage of these adventures. 😂💙🌸 💡 UNDER-CANOPY LIGHTING – MORE INTERESTING COLOUR OBSERVATIONS! Now, let's talk about one of the most interesting experiments inside Project Blue Tent. Our LumiFlora under-canopy lighting arrangement! As many of you already know, we're using two LumiFlora 150W full-spectrum fixtures positioned beneath the canopy in an X-cross configuration. These fixtures supplement our main overhead LEDs, which provide the primary illumination from above. And throughout this project, we've been paying particular attention to the lower sections of the plants. One of the observations we're making at this stage is that we're seeing more pronounced reddish colour expression around some of the areas receiving supplemental under-canopy illumination. It's particularly interesting when looking at the photographs and comparing different sections of the plants. We're also observing that the plants in this run are progressing towards the finish relatively quickly. However, I want to make an important distinction here. We're documenting an interesting association, not claiming that the under-canopy lighting or its red spectrum alone is responsible for the colour changes or faster finishing. There are several variables involved, including genetics, plant maturity, environmental conditions, and the overall lighting arrangement. To establish a direct relationship, we'd need a controlled comparison with appropriate measurements and comparable plants. For now, we're observing, photographing, and recording what happens. And that's exactly what this project is about. Experimenting, learning, and sharing the results without making claims that the observations cannot support. The two LumiFlora fixtures remain in their established X-cross configuration, and we're continuing with the same general approach. I'm genuinely looking forward to reviewing the complete project once everything is finished. A massive thank you to LumiFlora for making this experiment possible! 💡🌱💙 🌡️ THE ENVIRONMENT – FEELS LIKE SPRING OUTSIDE! Now, this is something worth mentioning! The outside temperatures have increased again. And we're not talking about a small difference during the afternoon. Even past midnight, we're seeing temperatures around 22.4°C outside! My friends, what is happening with the weather? 😂🌸 It almost feels like spring is trying to make an early appearance. But inside the tent, we're keeping things under control. Fortunately, our air conditioning is helping us manage the warmer outside conditions and maintain the established environmental targets. Our current reference conditions are: 🌡️ Day air temperature: approximately 25°C. 🌙 Night air temperature: approximately 20°C. 💧 Relative humidity: approximately 55%. 💧 Solution temperature: approximately 21°C. 🌱 Substrate temperature: approximately 21°C. 🌫️ CO₂ level: approximately 666 ppm. The important thing is that we're adapting to the outside conditions without making unnecessary changes to the established indoor environment. We're keeping an eye on the temperatures, monitoring the room, and allowing the air conditioning to help compensate for the warmer weather. As always, these are our reference operating conditions, rather than every temporary reading that might appear during maintenance. The girls have been developing under this general arrangement, and we're concentrating on keeping things stable as we approach the final stage. Outside: spring vibes. Inside: autumn colours. I think we've managed to create our own little season! 😂🍂🌸 💧 IRRIGATION – THE SYSTEM REMAINS UNCHANGED The irrigation and drainage arrangement continues operating as part of our established ecosystem. All four plants share the same reservoir and irrigation system. Our recorded watering volume remains approximately 1.6 litres per plant over 24 hours. This is our reference measurement, rather than an assumption that every plant consumes exactly the same amount. Individual demand can vary, so we continue monitoring the plants and the system. At this stage, we're not introducing unnecessary changes to an arrangement that's already established. The irrigation system remains in place, and we're concentrating on observing the plants as they progress. And speaking of irrigation, there's something new happening behind the scenes! But before that, let's talk about this week's nutritional change. 💧🌱 ⚗️ NUTRITION – PLAIN WATER FROM HERE! As explained in our previous reports, we've now reached the point where I've decided to discontinue the nutritional program and move to plain water. This change applies to all four plants because they share the same reservoir. Our current readings are: 💧 EC: approximately 0.2 mS/cm. 💧 pH: approximately 5.98. The EC represents our starting-point water reading. We're no longer adding: PLAGRON Hydro A. PLAGRON Hydro B. PLAGRON Power Buds. PLAGRON Green Sensation had already been discontinued earlier in flowering. We're also not using PLAGRON pH Plus or pH Minus for the current water. The natural pH is approximately 6.8 Why have we made this change? Because we're approaching the final stage, and after observing the flowers, the trichomes, the aroma, and the overall development, I've decided it's time to move away from the previous feeding program. The initial plan is to use plain water for a few days, potentially around one week, while continuing to observe the plants. We're not setting an exact harvest date based solely on this change. And an important clarification for anyone following the experiment: plain water doesn't magically remove nutrients from the flowers or guarantee a particular flavour outcome. It's simply the nutritional change we've chosen for this stage of our project. Our priority remains accurate documentation and observing the actual maturity of each individual plant. So, from this week onward: EC approximately 0.2 mS/cm. pH approximately 6.8 No additional nutrients. Let's see how the final chapter develops! 💙💧 🖨️ 3D PRINTING – BUILDING SOMETHING FOR THE NEXT RUN! Now, let's move away from the flowers for a moment. Because while the girls are approaching the finish, I'm already experimenting with something for our next adventure! 3D printing! I've been working on several prototype bases designed to sit beneath the watering points. The idea is to create a small distribution plate that helps spread the incoming water across a wider area of the coco surface. Instead of allowing the water to fall directly onto one concentrated spot, the design aims to distribute it more evenly. And that's what we're currently testing. I've printed several versions and have been carrying out small tests to observe how the water flows across the different designs. Will the distribution be more uniform? Will the shape need adjustments? Will we need to modify the dimensions? These are exactly the questions we're trying to answer. At the moment, these are prototypes, not finished products. I'm evaluating the designs and checking their practical behaviour before deciding which version, if any, will be incorporated into the next run. I've included photographs showing the 3D-printed pieces and some of the tests. And honestly, this is one of the things I love about cultivation. There's always something new to explore. Sometimes it's genetics. Sometimes it's lighting. Sometimes it's environmental control. And sometimes it's simply sitting down with a 3D printer and trying to improve a little detail in your irrigation system! 😂🖨️💙 We'll share more about these experiments as they develop. For now, it's another project happening behind the scenes while the girls finish their journey. 🔬 MATHILDA RETURNS – A LITTLE SPIDER PHOTOGRAPHY SESSION! And now, my friends… THE REAL STAR OF THIS WEEK'S PHOTOGRAPHIC SESSION! MATHILDA! 😂🕷️💙 Yes, our little spider friend is making another appearance! This time, we decided to bring Matilda along for a little adventure and let her explore while we captured some photographs. Nothing too serious. Just a bit of fun and an opportunity to experiment with macro photography. And honestly, she's a fantastic little subject! Look at those legs. The body structure. The details. The way she moves across the flowers. When you get close enough with a macro lens, even the smallest creatures become fascinating photographic subjects. It's incredible how much detail we can discover when we slow down and take the time to look. I've included several photographs of Mathilda because I wanted to share this little moment with everyone. Of course, she isn't part of our cultivation experiment! She's simply our unexpected photographic guest. 😂🕷️📸 And I think it's fair to say she's becoming quite comfortable in front of the camera. Mathilda, you're officially part of the Project Blue Tent photo collection! 💙 📸 MACRO PHOTOGRAPHY – THE BEAUTY IS IN THE DETAILS! Photography remains one of my favourite parts of documenting these projects. And during these final weeks, there are so many beautiful details to capture. The flowers. The changing colours. The trichomes. The textures. And, of course, Matilda! I'm continuing to experiment with macro photography and focus stacking. For anyone unfamiliar with focus stacking, it's a technique where multiple photographs are taken at different focus distances and combined into one image. The idea is to increase the depth of field and bring more of a small subject into focus. This can be particularly useful when photographing intricate subjects at high magnification. And between the flowers and our little spider friend, we've certainly had plenty of opportunities to experiment! I hope you enjoy the photographs as much as I enjoy taking them. Sometimes the smallest details make the biggest difference. 📸💙 🔭 THE FINAL STAGE – ARE WE APPROACHING HARVEST? My friends, we're getting close! Looking at the flowers, their development, the visible trichomes, the fading, and the overall appearance of the plants, I genuinely feel we're approaching the end of this adventure. We've already moved to plain water, and we're continuing to monitor the plants as they progress. But exactly when will we harvest? That's still something we'll have to determine. I don't want to invent a date simply because we're excited to reach the finish. We'll continue looking at the trichomes, the pistils, the overall flower maturity, and the individual condition of each plant. And remember, we're growing two different cultivars inside the same tent. Even the two phenotypes of the same cultivar may not necessarily finish together. That's another reason why keeping individual diaries is so important. Will Pickle Lemon Haze F1 Pheno A be ready before her sister? Will the Blue Waffle F1 girls follow a similar timeline? Will we end up harvesting the plants separately? Let's see! I'm genuinely curious to find out. For now, we're keeping things stable, continuing our observations, and allowing the plants to complete their journey. No rushing. No guessing. Just patience and good documentation. 💙🌸 💬 COME JOIN OUR DOGDOCTOROFFICIAL DISCORD COMMUNITY! Before we finish, I want to invite everyone to join our Discord family!

My friends, Week 15 has been another beautiful chapter for Pickle Lemon Haze F1 Pheno A. The flowers are looking fantastic, the density is impressive, and the fading is giving us a beautiful display of changing colours. We're seeing lighter green tones, warmer colours, and increasingly noticeable transitions throughout the plant. The under-canopy lighting experiment continues to give us interesting observations, particularly regarding the colour expression and the development of the flowers throughout the lower sections. We're also observing relatively fast progression towards the finish, although we're not attributing that to one particular lighting variable without further testing. The environment remains stable despite the warmer temperatures outside. The air conditioning is helping us maintain our indoor conditions, while the irrigation arrangement continues operating as established. We've now moved to plain water, with an EC of approximately 0.2 mS/cm and a natural pH of approximately 5.98. The major cultivation work is behind us. Now we're observing, documenting, and enjoying the final stages. We've also had Matilda joining us for another little photographic adventure, continued our macro photography experiments, and started testing our 3D-printed irrigation prototypes for the next run. So, although this week hasn't brought major changes to the cultivation setup, there's certainly been plenty happening behind the scenes! And as for Pheno A? She's looking beautiful, and I'm genuinely looking forward to seeing how the final chapter unfolds. Four individual plants. Two cultivars. One shared ecosystem. Different expressions. Different stories. And one incredible adventure that has given us plenty to learn along the way. Same tent. Same ecosystem. Same passion. Same love. And another beautiful week inside Project Blue Tent! 💙🥒🍂🌈❄️ 🙏 A HUGE THANK YOU – THE PEOPLE BEHIND PROJECT BLUE TENT!
