🌱 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. 🌱💚

- Drying for 3 days, the 2 airports-plants chopped and dried in the dehumidifier and the other 2 hanged upside down as they were. - Humidity -> 40-50% and temps -> 21-24C°.

Another great week for these 2. Lots of new crystals forming on the left one. I lowered the nutrient schedule for one week as I didn't want to ignore those early signs on one of the plants. Truth be told, if I had made 2 different nutrient solutions I could have still given full strength to one of them. Nevertheless, they are looking great. The smell however is a bit of an issue. The situation with the autos was 100% under control, zero smell issues. Not the case with this one. I even installed a new air filter and it still smell a tiny bit. It really is a micro amount, but it's annoying. First time I've had to think about any smell with this IKEA setup. Also, so far these don't look much like the real Purple Lemonade. The autos became really dark quite rapidly, I'm not sure these will get as dark.

She's fat, healthy and about ready to be chopped :) She will start flushing at the end of this week

All the girls seem to be finishing up now and the leaves fading. Auto is pretty much done. Another 7 to 10 days and the others should be done too.

Uma planta estava muito travada e pela minha experiência não vale a pena o custo da manutenção dessas plantinhas é chato mas preciso do espaço e do tempo para cultivar plantas que deem resultado. Coloquei um gancho leve em cada planta hoje para ver se aumenta a área verde.

Dropped light hours down to 16 . Topped off nutrient solution with 5.0 ph evened out .removed none chosen phenos to be flowered in separate room no longer tracking those we will only follow the chosen mothers clones i cut clones today as well had the lady friend clean floor with bleach and dawn put clones in ez cloner 32 systems

This strain is growing well and fast I’m it. The images with the damaged stem came from the ties I used they were too tight and it shouldn’t have done that much damage but it did so. But that’s some stress training and it’s healed nicely.

Feliz por como van mis gorilas, todos los días hay cambios y cada semana tengo que aumentar el riego, esta semana utilice en total 18 litros, 4.5 litros para cada planta aproximadamente. En los primeros 6 litros uso: ▪️︎4ml de Connoisseur A y B por litro de agua. ▪️︎2ml de Rhino por litro de agua. ▪️︎2ml de Bud Candy por litro de agua. ▪️︎2ml de Carboload por litro de agua. ▪️︎2ml de B-52 por litro de agua. Espero 30 minutos y despues aplico otros 6 litros con los siguientes nutrientes: ▪️︎4ml de Connoisseur A y B por litro de agua. ▪️︎2ml de Nirvana por litro de agua. ▪️︎2ml de Big Bud por litro de agua. ▪️︎2ml de Overdrive por litro de agua. ▪️︎2ml de Voodo Juice por litro de agua. No tengo medidor de EC, por lo tanto trato de que las mediciones en ml sean exactos con una jeringa. ☆ 1 día a la semana riego las plantas con 6 litros de agua sin nutrientes y con un PH en 6.0, hasta el momento no han presentado carencias pero tengo la duda si tienen exceso de nitrógeno por el color verde intenso de las hojas.

She has reciver very well and now growin tall. Looking foward on what will come out from this CBD strain so I can make some CBD oil

12/30 MONDAY 4am MB 4g & 0.8ml Purpinator. I tried Liquid KoolBloom, it's ok. 2pm Put the small Orion cola in a jar, not a big producer under my grow conditions but it smells and tastes just beautiful. LOTS of resin very sticky smokes just fine after hanging to dry for a couple days. 12/31 3am. 1pm took another cola from Orion about 1.5 wet so maybe half oz dry. Small grows are still the way to go for me. EVERYTHING is just so much easier, less messy. I get about the same amount from 1 gallon indoor soil grows than I did from HUGE 3 gallon fabric pots that I used Outdoor soil...infected shipped all over the country so every kind of bug.... I did NOT know to use airtight INDOOR specific soil or it will have BUGS & MITES...., like Root Mealy Bugs that will eat the roots as they grow...I didn't know that could happen!!!! 1/1 4am they are great 1/3 11 am Took the smallest cola from Cookie Apple & arranged the plants closer together. They fit like a puzzle as I take each cola & require a little less water. 1/4 2am

6/10/2024 the fades coming in nicely. I probably could have pushed her with nutes for a couple weeks and possibly gotten her to thicken up a bit. But she is pretty thick as is. She's going through water quick and I keep forgetting and so she's finishing a bit quicker I think. I may chop soon but this plant is probably a 90 day strain. I feel like most autos can fall into that range 6/15/24 she was cut. I will add a harvest week soon.

The ladies are packing on beautifully and we are now giving them extra strength light during 12:00 till 14:00 slot 100% and lowering the light back down to 75% from 14:00 till 17:00 and then 50% light from 17:00 till 23:00. Lets see what happens

💚🌷

Flower's are coming through lovely Day 17

Hoy les toco riego, con enhancer, piranha y bac bloom. Se sumara a la alimentación bac booster y top candy.

So, things are going great. The RO water change left me with a nice sterile clean res. The plants are loving the lighter feeding and it shows.
