Day 14: These little plants are just truckin along. They’re looking good. They seem a bit small, but are indica dominant so idk yet. I’m heading out of town for a couple days so they’ll get a heavy water and be left on cruise til I’m home. The Fast Buds from last round are curing up nicely and so powerful in potency and aroma. I’m pumped to see how these turn out. The XS2000 is providing a perfect amount of heat at 75% that it just takes a light misting to have these little plants right in the sweet spot for temps and humidity. I’ve said this a bunch, this is a powerful light so I have it set a bit higher than recommended but I want room for them to grow up into without stress. I’d rather have a bit of stretch to contend with rather than light stress. I’m excited to see how they look when I’m home. Hopefully quite a bit bigger!! Happy Growing 🌱

Gary Patron - Nine Weeks Harvest Day 122 🚿 I've watered her every three days with 2L of RO tap water, pH'd to 6.3👌🏻 I'll be leaving her to dry back over the next couple of days in preperation for harvest, which is a few days from now 💪 ✂️ No work on her this week, as I gaver her a good defoliation last week - she will be getting a wet trim and more defoliation a day or two before I harvest her. 🌸 Shes in week nine of bloom, and her flower is absolutely covered in trichomes, mabye the most I've ever seen - the majority of her trichomes have turned milky clear with some ambers starting to appear. Her pistils have also all dried and turned amber, which on the backing of her vibrant lime green flower with some purple tips, is both striking and inviting. I will leave her to finish maturation over the next couple of days, while I fight with the temperatures trying to keep them in the 20's with the weather we're having at the moment! I'd say shes about 3-5 days from harvest at this point 👍

Video 2: 4 days (25~28) TimeLapse, 1 image each 60 secs @ 30 fps, awesome video of how is responding the main Gorilla to the Man Linning, at about minute 2:00 i pruned and trained the other gorilla and the main Money Maker, and at the end of the video i pruned the last Money Maker. Video 17: General video of the 4 plants and it's trainings, i'm sorry for being so repetitive with the music. Video 18: Video focushed on the second Gorilla Photo 10: Top and bottom cuts marked on photo 11 Photo 26: Last main branches toppings Photo 29: The main internodal became very rocky, awesomly robust. -----WEEK SUMMARY----- As you see i'm testing many different things among the plants, the first Gorilla is recieving a heavy training in man-lining, and with the second gorilla im trying to equilibrate all the tops and then i will push them horizontally, also i twisted the main branch a little so there's no node below any other. I love how the man-lining is forming the plant, but i'm really scared as i really don't know what am i doing, i just sin in front of the plant some minutes, and then i cut where i fill, same with the grab points. please don't be too enthusiast with this growing as maybe i will fuck up everything at some point lmao!! 😭 -----WATERING CALENDAR----- 18/03/19 - 400 ml with all "LAST" week nutrients @ 0.95 E.C. PH5.9 (i had some rests from the last watering) - Also i applied a foliar irrigation with the same mix as the last week 20/03/19 - 1.000 ml with all week nutrients @ 0.9 E.C. PH5.9 *****ESPAÑOL***** -----IMÁGENES & VÍDEOS----- Vídeo 1: TimeLapse, exactamente el mismo vídeo que el 2 pero acelerado a un poco más del 300% para ajustarlo a 1 minuto para Instagram. Vídeo 2: 4 días (25~28) TimeLapse, 1 imagen cada 60 segundos @ 30 fps, vídeo increíble en el que se ve com responde la Gorila al Man Lining, en aproximadamente el minuto 2 podo y entreno un poco a la otra Gorila y la principal de las Money Makers, al final del vídeo podaré la última Money Maker. Vídeo 17: Vídeo general de las 4 plantas y sus entrenamientos, siento la repetitividad de la música entre los vídeos. Vídeo 18: Video enfocado a la segunda Gorilla Photo 10: Los cortes nombrados (Top&Bottom) de la foto 11 Photo 26: Los toppings de las ramas principales. Photo 29: El internodo que he dejado como principal se ha puesto duro como una piedra, extremadamente robusto. -----SUMARIO SEMANAL----- Como se puede observar estoy probando diferentes cosas enter las 4 plantas, la primera de las gorilas está recibiendo un man-lining y entrenamiento bastante heavy, y con la segunda Gorila intentaré equilibrar las partes altas y después la extenderé horizontalmente, también he torcido el tallo principal para que los pisos se distribuyan en círculo. Me encanta como el man-lining está distribuyendo la planta, pero estoy muy asustado pues realmente no se lo que estoy haciendo, simplemente me siento delante de las plantas un rato y después las meto cortes donde siento, de la mima manera las estoy agarrando. Por favor no seáis muy entusiastas con este cultivo, pues en cualquier momento puedo liarla y destrozarlo todo Jajajajajajajaj 😭 -----CALENDARIO DE RIEGO---- 18/03/19 - 400 ml contodos los nutrientes de la "ÚLTIMA" semana @ 0.95 E.C. PH5.9 (me quedaba un resto del útlimo riego) - También he hecho un riego foliar con un resto del ultimo riego foliar 20/03/19 - 1.000 ml con todos los nutrientes de la semana @ 0.9 E.C. PH5.9

It's week four of flowering, and Blue is doing her thing, slowly developing her buds. Outside, the temperatures are slowly rising to around 17°C during the day. This means that during the dark phase, the temperature in the tent no longer falls below 19°C, so the Calmag can be transported more easily. Keep it IZI 💚

Harvest Notes ✂️ • Harvest Timing: Papaya Zoap was harvested at day 63, with select buds taken earlier at day 56 due to mold concerns. • Drying: After careful trimming, the buds were dried for 12 days. The quality and aroma during drying hinted at the stellar smoke to come. • Density & Yield: Buds were rock-solid, delivering an excellent yield with perfect density for storage and enjoyment. Terpene Profile & Aromas 🍋 • Primary Aromas: A tropical explosion with sweet papaya upfront, complemented by creamy, soapy undertones that make her truly unique. • Complexity: As the buds cure, a hint of citrus zest and exotic fruit emerges, creating a full-bodied terpene profile that’s simply irresistible. Cultivation Experience 💡 • Highlights: Her uniform growth, heavy trichome production, and response to super cropping made her a delight to grow. She thrived under careful spectrum adjustments and defoliation, showcasing her adaptability and vigor. • Challenges: The dense bud structure made her more prone to mold, especially in a high-humidity environment. However, proactive monitoring and swift action mitigated the spread. Verdict: 🌟🌟🌟🌟🌟🌟🌟🌟🌟🌟 (9.8/10) Papaya Zoap is a strain that commands attention with her beauty, aroma, and unstoppable growth. While her susceptibility to mold required extra care, her overall performance, yield, and quality were nothing short of exceptional. A grower’s dream and a frosty masterpiece!

Starting week 3 today, with a challenge ahead with this little bad girl! It seems to be a lack of Nitrogen, and I'm pretty afraid of burning the plant. I'm feeding the plant once each two days, with Seaweed Tonic, 150ml with the suggested dilution from the bottle. Now I have also a bottle of Canna Terra Vega, with NPKS 3-0-3-0. Is it a good idea to start feeding the plant, with also this nutrient? The soil is a mixture of 80% organic soil + 20% of coco coir. Could be a lack of nutrients from the soil? What is the best agenda to follow with nutrients? (: Cheers!! UPDATE (17/02 - Day 17): based on the suggestions made by many members, I've tried to gather the best of all and decided to make some moves in an effort to save this plant, and to avoid the same situation to the other 2 plants: #1 - Lifted the LED panel to double of the height, so the distance to the plants went from 50cm to 100cm #2 - This change with the distance from LED panel helped to low down the highest temperature achieved during the day from 27.5°C to 24°C #3 - Since day 15, the plants haven't been watered, in a move to try to dry a little bit the soil, once I was watering every day with something close to 250ml a day. Now I'll return with water in a few days, while I wait for some signals from the plants that they are needing water #4 - Pushed forward the idea to start feeding them this week, and maybe I give just a little bit of seaweed solution to root development when I come back with watering. Hope it works fine!

It is so very hot now every day here. All my girls are suffering from the heat and they need to be watered very frequently. I avoid drying them out completely. Both plants are doing well in the heat. I prefer the structure of the mainlined plant.

Day 43 : Watering with co2 tab / 5L. Also added food again because i think they need it. Increased ppm to 850. Maybe the next one will be pure water. Ventilation works all the time when lights are on. Temp and humi are stable and this is good for the girls. she still grows. Patience is the key always. Also removed some burned leaves from all ladies. Edit (Day 47) : Watering with co2 tab every 5L. I watered with juices again at 850ppm because i felt that they need it. Only DsD drank pure water because of burns. All ladies enjoy this bright sun for sure. I have a very good combination of sprectrums. Cree cobs are in 3000k and HPS at 2000k.

? Blueberry Muffin – Pheno B Week 9 | Same Genetics. Completely Her Own Story. 🌿🔥 Welcome back to another week of the 8×8 Adventure! 💚🌱 If you've been following these individual phenotype diaries, you already know that I absolutely love this part of the project. Because sometimes you can take two plants from the same cultivar... Give them the same environment. The same light. The same irrigation. The same nutrition. The same room. And still end up with two plants that look like they were given completely different instructions. That's exactly what we're seeing with these two Blueberry Muffins. And this girl? She's writing her own story. She's compact. She's lush. She's beautifully structured. And she's becoming increasingly interesting as flowering progresses. This week was another step toward giving her the space she needs to turn all that beautiful structure into flowers. So let's have a look at what our little Blueberry Muffin Pheno B has been doing. ?🌸 🌱 Week 9 – The Compact Sister Blueberry Muffin Pheno B has never been interested in becoming the tallest girl in the room. And honestly? I don't think she cares. She's approximately 75 cm tall, but height doesn't really tell the story with this phenotype. Her personality is in her density. She's compact. She's leafy. She's got a strong central structure with flowering sites distributed throughout the plant. And as flowering has progressed, that compact architecture has become even more obvious. This is where growing multiple phenotypes becomes so much fun. Her sister has her own architecture. This girl has hers. Neither one is trying to imitate the other. They're simply expressing what they have genetically programmed inside them. And I absolutely love it. 🌸 Flowering Development – She's Filling the Space The flowers are now becoming much more established throughout the plant. The fresh white pistils are everywhere, and the individual flowering sites are becoming increasingly recognizable. What I particularly like about Pheno B is how much flower development she's carrying inside such a relatively compact structure. She's not using a huge amount of vertical space. She's using the space efficiently. Branches are filling in. Flowering sites are developing. The canopy is becoming increasingly dense. And this is where our job as growers changes slightly. Earlier in the grow, density was simply beautiful. Now that we're moving deeper into flower, we have to think about what that density means for: 💨 Air movement 💡 Light penetration 🌡️ Microclimate 💧 Humidity management 🌸 Flower development And that's exactly what we're doing this week. ✂️ Cleaning the Canopy – Making Room Like her sister, Pheno B also received some selective defoliation this week. But there's an important distinction. We're not cleaning her because she's doing something wrong. We're cleaning her because she's doing too much of a good thing. 😄 She's naturally compact and very leafy. And as the flowers develop, some areas can become quite crowded. So we're opening her up a little. Removing selected leaves that are overlapping. Removing foliage that isn't contributing much anymore. Creating some breathing room around developing flowers. And generally making the architecture easier to manage. This isn't about stripping the plant. Far from it. She's still beautifully green. She's still carrying plenty of healthy foliage. We're simply creating a little more space between everything. Sometimes the best canopy is not the one with the most leaves. It's the one where every remaining leaf has room to work. 💨 Airflow – Especially Important for This Girl This is probably even more relevant with Pheno B than it is with her sister. Because this girl is compact. And compact plants naturally create more areas where leaves and flowers can sit close together. That can be beautiful. But as flowers become denser, I don't want stagnant little pockets developing inside the canopy. Good airflow is one of those things you don't really notice when everything is working properly. And that's exactly how I like it. Air moving through the plant. Humidity being managed. No unnecessary congestion. No little hidden corners where moisture can sit. We're not trying to create a sterile plant. We're simply trying to make the environment less friendly to problems such as mildew or mould as flowering progresses. Prevention is always easier than dealing with a problem later. 💡 She's Compact – So Let's Use the Photons This is another reason I like opening her up a little. At around 75 cm, she's not particularly tall. And that's perfectly fine. But when you have a compact flowering plant, I want to make sure the available photons can actually reach the places where they're useful. She already benefits from the additional light strategy we're running in the room, including the inner and under-canopy lighting. That's a huge advantage. But even with additional lighting, there's no reason to let unnecessary layers of foliage block one another if we can naturally improve the canopy. We're not trying to expose every flower directly to the light. We're simply creating pathways. Light pathways. Air pathways. And observation pathways. That's what this little cleanup is about. 🌿 Still One of the Lushest Girls in the Room And after the cleanup... Look at her. She's still lush. She's still green. She's still compact. And she's still unmistakably Pheno B. This is something I really wanted to preserve. I don't want to turn her into a completely different plant just because we removed some leaves. The phenotype is the phenotype. Our job isn't to erase that. Our job is to help her express it as efficiently as possible. And I think we're getting a really nice balance now. Enough foliage to power the plant. Enough space to let the canopy breathe. Enough structure to support the developing flowers. And enough visibility for us to actually see what's happening. That's a pretty good combination. ? Two Sisters – Two Personalities This comparison is becoming one of my favourite parts of the entire 8×8 Adventure. Because if you put Pheno A and Pheno B side by side, you can immediately see that they're related... but they're not identical. Pheno A has developed her own open architecture. Pheno B is the compact, lush sister. Pheno A has been a little more demanding in some areas. Pheno B has generally looked extremely comfortable with the current environment. And yet both plants are producing their own beautiful version of Blueberry Muffin. This is exactly why I don't like forcing every plant into the same training schedule. If I had tried to make these two plants behave identically, I'd have removed some of the most interesting information this grow is giving us. Instead, we're allowing the differences to remain visible. Same genetics. Different phenotype. Different personality. Different expression. And that's the story. ⚗️ Nutrition – No Need to Fix What Isn't Broken The feeding programme remains unchanged this week. We're continuing with: Terra Bloom – 2.2 ml/L Pure Zym – 1 ml/L Sugar Royal – 1 ml/L Power Buds – 1 ml/L pH adjustment as required Current solution is around: pH 6.0 EC ~2.0 mS/cm And Pheno B continues looking very comfortable with it. She's maintaining that beautiful green colour. She's developing flowers. She's growing normally. And there are no obvious reasons to start changing the recipe simply for the sake of changing it. That's one of the things I've learned during this project. When the plant is happy... sometimes the smartest thing you can do is leave it alone. 🌡️ The Room – Small Changes, Same Stability The environment has changed slightly compared with some of our earlier updates, but we're still maintaining a very stable room. Current conditions are approximately: 🌡️ Day temperature – 29°C 🌙 Night temperature – 25°C 💧 Relative humidity – 60% ⚗️ pH – 6.0 ⚡ EC – ~2.0 mS/cm 💨 CO₂ – ~693 ppm 💦 Watering – ~1.3 L/plant/24h 🌡️ Solution temperature – 25.2°C 🌡️ Substrate temperature – 25.6°C 💡 Light schedule – 12/12 ? Pot size – 15 L So we're sitting around a 4°C day/night temperature difference. And again, I don't look at any one number in isolation. Temperature interacts with humidity. Humidity interacts with transpiration. Light affects plant demand. Root-zone conditions affect water and nutrient uptake. Everything is connected. And at this point in flower, I'm particularly interested in keeping the relationship between those factors stable rather than chasing some theoretical perfect number. 💨 Opening the Canopy Helps the Whole Room There's another reason I'm happy we cleaned her up this week. It's not just about Pheno B. When you've got a room full of flowering plants, every canopy contributes to the overall environment. More open foliage means air can move through more easily. More airflow means fewer stagnant pockets. And better movement through the room helps the environmental system do its job. Again, defoliation isn't a replacement for proper ventilation or environmental control. But good canopy architecture and good environmental management work together. And that's exactly what we're trying to achieve. 🔬 A Plant That's Becoming Easier to Read One thing I really appreciate about Pheno B is that she's becoming easier and easier to understand. At the beginning, we didn't know what she was going to become. Now we do. She's telling us: "I'm compact." "I'm vigorous." "I'm leafy." "I'm going to build my flowers inside this structure." And our response is simply: "Okay. Let's work with that." That's what I mean when I say grow with the plant, not against it. We're not trying to make her taller. We're not trying to make her look like Pheno A. We're not trying to turn her into something she's not. We're simply giving this particular phenotype the conditions and space she needs to perform. 📸 The Camera Doesn't Lie The photographs this week really show how much she's changed. The close-ups reveal those developing flowers and their increasingly defined structure. The wider photographs show just how much vegetation she's carrying around those flowers. And then there are the little details. The colour. The leaf posture. The branching. The way the flowers are distributed. Those details are why I love documenting individual phenotypes. A single photograph can show what the plant looks like. But a series of photographs over several weeks shows who the plant is becoming. And Pheno B is becoming a very beautiful little flowering plant. 🔮 Looking Ahead From here, I'm not looking to make any dramatic changes. The major framework is already there. The selective cleaning has given her some additional breathing room. The environment is stable. The feeding is stable. The flowers are developing. Now comes the part where patience becomes increasingly important. Over the coming week, I'll be watching for: 🌸 Continued flower development 🌿 Increasing density around the flowering sites 💎 Early resin development 💨 Continued airflow through the canopy 💧 Stable water demand 🌡️ A stable flowering environment And most importantly... I'll be watching the plant. If she tells me she needs something, we'll respond. If she doesn't... we let her work. 💭 Final Thoughts – Her Own Little World There's something really satisfying about this plant. She isn't dramatic. She doesn't need to be. She's just beautiful. Compact. Lush. Healthy. And increasingly covered with developing flowers. And what's especially fascinating is that her sister is doing something completely different while receiving essentially the same treatment. That's the magic of phenotype hunting. You don't know exactly what you're going to get. You give the genetics the same opportunity. Then you watch. And eventually... they introduce themselves. Pheno B has introduced herself as the compact, lush, elegant sister. And I really like her. This week wasn't about changing her. It was about giving her a little more room to breathe. A little more room for photons to move through. A little more room for air. A little more room for those flowers to develop. And now... she's ready. The canopy is cleaner. The flowers are becoming more defined. The environment is stable. The nutrition is steady. And this beautiful little Blueberry Muffin is heading deeper into flower. Let's make her shine. Let's give her the spotlight she deserves. Because she may be the compact sister... but she's certainly not a small personality. ?🌸🔥 🙏 Thank You As always, a huge thank you to everyone following the 8×8 Adventure. Thank you to Zamnesia for these beautiful Blueberry Muffin genetics and for giving us the opportunity to explore just how differently two phenotypes from the same cultivar can express themselves. Thank you to Plagron for supporting the plants with the growing media and nutrition throughout the journey. Thank you to Future of Grow for providing the lighting that allows these twelve different genetics to perform under the same artificial sun. Thank you to Lumiflora for helping us bring additional light into the inner and lower parts of the canopy. Thank you to TrolMaster for helping keep the environment stable. And, of course, thank you to everyone in the GrowDiaries community. Every comment. Every question. Every observation. Every person simply stopping by to see how the girls are doing. It all makes this adventure more enjoyable. Two Blueberry Muffins. Two phenotypes. Two personalities. And we're nowhere near finished discovering what they can do. Until next week... Growers Love and happy growing! 🌱💚? See you next week with Blueberry Muffin Pheno B. 🌸🔥

Day 78🌱🙂🍊 This lady is doing her great job, Buda are increasing rapidly 🌱 difference between top flower and bottom is evident. For this reason I’m quite sure I’m going to cut in two times, around 85/87 days I’ll cut the high part of biggest bud and around day 95 the rest of the plant. Day 80🌱🌱🌱🙂🍊 I’m going to go up to 90/95 days, smell now is really strong 👃🌱🤣 I keep giving some water when is really dry because some parts of the plant still needs it. Day 81 🌱🌱🌱🌱🙂🍊 Hi all fellows, today a big defoliation cleaning to improve light in the bottom Part of the plant before harvest. I tought to harvest in like 10 days but as I have some water yesterday I noticed that she’s been quite not drinking anymore. I’ll give another 2/3 days before harvest. I will be perfectly in 85 days from seeding. Smell is crazy now, I can smell cotton, orange, chocolate, pinus.. can’t wait to try it. Let’s see! ANY SUGGESTION IS REALLY WELCOME 🌱🌱🌱🌱🌱🌱🌱🏆🏆🏆🏆😊😊😊😊
