🌱 Black Diamond Auto – Plant B | Week 4 | 12/12 From Seed Another Diamond Begins to Show Its Shape 💎 Welcome back to another update from my 8×8 Adventure, where every plant gets the opportunity to tell its own story. This is Black Diamond Auto – Plant B, the sister of Plant A. While they share the same genetics, the same environment, the same feeding schedule and the same light, it’s already fascinating to watch how differently they choose to grow. Plant B has developed into a much more compact structure. She isn’t chasing height like her sister—instead she’s building a dense, symmetrical framework with tight internodal spacing and a very healthy canopy. Sometimes the smallest plants surprise us the most once flowering really begins. Both plants are being grown under my favorite challenge: 12/12 from seed. For those joining the diary for the first time, this means the plants have been under a 12 hours on / 12 hours off light schedule from the day they germinated. Instead of spending weeks in vegetative growth under 18 or 20 hours of light, they naturally transition into flowering much sooner, creating unique plant structures while allowing more harvests throughout the year. Every run teaches something new, and this comparison between two sisters should be another interesting chapter. ⸻ 🌱 Environment This week the room remained very stable despite the summer temperatures. • Day temperature: 33°C • Night temperature: 25°C • Relative humidity: 63% • pH: 6.1 • EC: 1.35 mS/cm • CO₂: 639 ppm The plants continue growing inside 15 L pots, receiving approximately 1.1 L of nutrient solution per day. ⸻ 💧 Hand-Watering vs AutoPot Unlike her sister, Plant B is still being hand-watered. Both plants receive exactly the same nutrient recipe, but the irrigation method is different. This should make for an interesting comparison later in the grow. Hand-watering gives me complete control over when and how much solution she receives, allowing the substrate to go through gentle wet and dry cycles before each irrigation. Her sister, meanwhile, is growing inside an AutoPot system. The AutoPot uses an AquaValve, a clever mechanical valve that automatically opens and closes depending on the water level inside the tray. As the plant drinks, the valve refills the tray without pumps, electricity or timers, allowing the roots to take exactly what they need whenever they need it. Will continuous bottom feeding produce faster growth than traditional hand-watering? That’s one of the questions this grow hopes to answer. ⸻ 🌿 Training No topping. No supercropping. No heavy stress. This week has been all about Low Stress Training (LST). Branches continue being gently bent outward to improve light penetration across the canopy while maintaining an even structure. Every day I spend a few minutes adjusting stems, leaf tucking large fan leaves and opening small windows of light for the developing side branches. It’s amazing how much a few careful adjustments can change the architecture of a plant without causing any significant stress. The goal is simple: * create an even canopy * expose future flowering sites * maximize airflow * let every branch earn its place under the LEDs Plant B has responded beautifully, staying compact while becoming wider with every passing day. ⸻ 🌸 The First Signs of Flower By the end of Week 4 the first pistils are finally appearing. This is always one of my favorite moments in a 12/12 from seed project. The transition happens naturally, almost quietly, until one morning those first white hairs appear and you know the next chapter has officially begun. Stretch is only beginning, but her structure suggests she’ll remain shorter and bushier than Plant A. Two sisters. Same genetics. Same room. Same nutrients. Yet completely different personalities. That’s exactly why I love documenting every individual plant. ⸻ 🍽️ Feeding This week’s recipe remained simple and consistent: • Terra Grow — 1.8 ml/L • Power Roots — 1 ml/L • Pure Zym — 1 ml/L • Sugar Royal — 1 ml/L EC remained at 1.35, with pH adjusted to 6.1 before every watering. She continues responding with vigorous growth, healthy color and strong new shoots throughout the canopy. ⸻ 📸 Final Thoughts Watching siblings develop side by side is one of the most rewarding parts of growing. Plant A seems determined to become the taller, more vigorous sister. Plant B is taking a different path—shorter, denser and incredibly well balanced. Neither is better. They’re simply expressing different sides of the same genetics, and that’s exactly what makes these side-by-side diaries so enjoyable. The stretch has only just begun, flowering is officially underway, and I’m excited to see whether hand-watering can keep pace with the AutoPot system over the coming weeks. Only time—and plenty of photos—will tell. ⸻ 🙏 Thank You As always, thank you to everyone following this adventure from around the world. To GrowDiaries for providing a platform where growers can learn from one another. To Plagron for the nutrients that continue feeding this project. To the incredible breeders behind Black Diamond Auto. To the teams behind the LEDs, the equipment and every tool helping make this grow possible. And finally, thank you to every person who stops by these diaries. Whether you’ve been here since day one, discovered the journey this week, leave comments, ask questions, share advice, quietly read along, or even challenge my methods—you all contribute to making this project better. Every interaction is another opportunity to learn, improve and keep growing together. Growers Love and see you all next week. Happy growing. 🌱💚

Ise grows incredibly fast and gets such huge leaves. I'm curious to see how big the flowers will be.

You can see the girls on week 4 right at the end of video aprry didn't get much time with plants this week will update more in the coming days the ones flowering are on day 5 the rest will veg untill there finshed

Hello everyone 😎 Week 4 for my girl She is doing very well,growing at fast pace and with a beautiful green colour on the leaves. For the feeding schedule half grow half bloom + 1ml/L power buds Have a nice day 😎

Day 75. She’s huge and in the dark ice flushing. She smells amazing. I can not wait! 🎂🎂🎂🎂 we also added another meet Mortimer

Spray evolution one's a week

shortest plant is 50cm tallest being 95cm. They are all doing wonderfully, most of autos are budding nicely and all of the photoperiods are ready to flower. looking very promising. i am changing my light schedule to 14-10 to kick these girls into flower.. this will give the plants an extra 17% (or so) a day under the lights.rather than 12-12. i cant be fussy as i only have one grow space but if my research is correct these should grow beautifully! the autos are well ahead so shouldnt affect my harvest weight too much. like i say i cant be fussy! thanks for looking

So we have harvested the wedding cheesecake abruptly as I think one might have started too herm possibly as I saw signs hence the abrupt chop of all as only days away from end of week 8. There are no seeds or any disinformation yet I saw under scope slight growing signs of possible coming g of herm so didnt waste time too chop... will inspect once dry all should be okay 🤞 The buds smell absolutely delicious theres more of a creamy cakey aroma bursting through more than anything like a creamy woft through the air. The girls grew amazingly considering I went from auto feed too hand feed although didnt seem too have a negative affect end result shows so I'd like too re run the wedding cheesecake ff again solely by hand/autopot this time all way through. Buds form grameat with great resilience too conditions out of control as I myself have a heatwave and they seemed too handle well. Over all I would strongly recommend this monster of a grower too all, she is a beautifull strain with such a great growing process. I will keep one girl for flower and the not so perfect girl for hash or too be pressed once cured for a month or so... These were flushed only a week unfortunatley due too early chop but as in coco I'm sure I'll be fine after a cure even for the hash girls.

14 march on day of bloom 52 🌺 Ztrawberry soon ready to harvest!

Start of week 6! Week 5 went well, the girls are all very sticky and smell incredible! The super lemon haze continues to need extra feeding, she's a hungry lady! Both blueberry plants are packing on a lot of weight as the branches are bending and twisting, I tried them up to give them extra support.

There are some smokable buds but most of these are for seeds…I will wait the seeds to finish mature then consider the smokable buds…so far so good

Started noticing some nitrogen problems from growing in MiracleGrow

…

Throughout the week, I give compost tea, and fermented plant juice once each ^^ Hope you guys have a wonderful day today ^^v *** Please Like, comment & share *** Highly appreciated -----/-----<@

El ph se controla en 6.5, la temperatura la tenemos entre 24/21 grados y la humedad ronda el 50%. El ciclo de crecimiento puse 12h de luz, el foco está al 50% de potencia. Tengo visitantes, trips que combatiremos con control biológico. Me gustaría estar más encima este cultivo pero la salud me está impidiendo un poco este 100% con el proyecto. - os dejo por aquí un CÓDIGO: Eldruida Descuento para la tienda de MARS HYDRO. https://www.mars-hydro.com Hasta aquí todo, Buenos humos 💨💨💨

Smells awesome! She’s getting thick! I was worried about how tiny she was. But she’s perfect ✌️❤️

took my old filters from my full ecosystem fish tank and rinsed them out in the water i gave to the girls. This will be just the same as using fish shit and it will make the buds big and sticky. Next week will tell if it worked.

Strain: Guava Sundae Grow Type: Indoor Nutrient Line: Athena Harvest Update ✂️🌿 This was another beautiful one to bring across the finish line. The buds came out dense, colorful and absolutely covered in gorgeous deep purple hues. The smell was just simply amazing a really nice fruity smell. Between the colours, structure and terps, these girls definitely were amazingggg Overall, I'm really happy with how this strain turned out. The buds look amazing, smell even better and I'm definitely looking forward to seeing how those fruity terps come through after a proper cure 🌿🔥 Recommended Drying Conditions 🌡️ Temperature: 18–20°C 💧 Humidity: 55–60% ⏳ Dry Time: Approximately 10–14 days And don’t forget to use my discount code ISLANDT for 15% off your next order at Fast Buds 🌿🔥
