Week 1 Flower We finally got the Surf Purp siblings into the flower tent Playboiis! 👍 Now they'll be growing at a faster rate throughout the transitional period, silicon has been increased a bit so they stay thick and strong, and also bendable if needed. Remo grow has been significantly reduced whilst remo bloom is now being added at the same strength as micro. A very small amount of Astro flower is being added too. Epsom Salts has been doubled along with Cal-Mag being upped very slightly. I always feed at 5.9pH when in the transitional period/stretch and then increase to 6pH once in full bloom. This is to slowly transition their pH to 6 as this is a better pH for the required nutrients throughout flower. Because they haven't yet had the usual maintenance flush after being delayed in veg, I gave them one on Day 6 Flower. They were topped up with a nutrient feeding straight after to ensure they don't go hungry! I checked the ppm and pH of the tun off for each of them before flushing mote water through them. This is to check if they're roots are happy and healthy with a good pH and feeding well, without leaving a high ppm in the run off. The strings that they're under were already there from the previois girls, but was sterilized before putting the Surf Purps in. These were enough to move all the branches required to open them up and spread them out evenly. Because I'm only flowering under one light, the two outer plants (1&3) won't be getting the same intensity as the other two, so they'll more than likely produce smaller, less dense flowers (if they're female). It's just something that'll need to be considered when picking a keeper as they could produce the same, or bigger flowers if given the same intensity as the other two. I placed the two tallest plants at the back as they look like they'll stretch the most out of the bunch, so it makes the two smaller plants at the front easier to see and tent to the canopy. They're all looking healthy and a nice colour overall. They're all looking healthy and a nice colour overall. They were all given a good defoliation on Day 7 to slow their stretch, now that their growing at a much faster rate. We'll soon see their pre flowers to determine what sex they all are! Thanks for following and happy growing! 🐺

Removed the firsts/fake leafs. Will do LST on ZZ Punch #1 on this week!. With goal to get two the same size and can see the differences between in Normal Grow and with LST :) On 3rd day of 5th week I have done LST on #1.

A day late but Yes looking good. You can observe the new set of leaves. She's adapted nicely into a bigger container.

Tall. And. Volume

Der Herbst ist da!!! Die Blüten machen sich gut und ich sehe täglichen Fortschritt

Definitely happy with the grow and the quality of the smoke

Week 4 of flower

2/18: 4 weeks since we planted them. Some of the new nodes since topping are starting to come in. Also finally got to doing some lst. First time, so I didn't rlly know what I was doing all that much, but my main goal was to pull branches outward and have more light reaching all the nodes. I should definitely have topped and done LST earlier, but oh well, now I know for next time. I also removed some of the new fan leaves that were covering the new nodes. My roommate wanted to experiment with the smallest one so removed some of its big fan leaves. I don't really think that was the right call, but whatever we'll see what happens. Would also have loved to try mainlining but its also pretty late for that. It would have slowed down veg quite a bit too, and since we have to go home from college in early may, they have to be harvested by then. Gonna water later this afternoon as well.

Could probably harvest three of the four of I was short of smoke. Ones lagged behind a little, but I'm in no hurry :) Classic Kush smell and these have been real quick to flower. I know there's a lot of new strains around with quirky names but honestly everyone should have a Kush grow and these are a good place to start that Kush adventure. Been real easy to grow, stayed low, no silly stretch and no complex needs. Good signs of strong genetics. You could do a LOT worse than pop these for your next grow. Hopefully the smokes as good as the smell. Going to leave these on plain water with a dash of calmag as long as possible, see how stanky they get when left a little over ripe. Ten days maybe 🤔

Just water

I’m on demon time

🌱 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.

Nach nur 3 Tagen gekeimt, FastBuds Qualität... Eingetopft in den Endtopf.. Bon Appetit little Madame Apricot!!

almost finished

Time to flush

Picked up this Clone today. Excited to see what I can get with her. She's testing super high in terps and cannabanoids. Win win.

Stretched a bit. Ramping up their nutrients. She’s doing well! She had a prominent main cola. She’s not as big as the other testers. Bu tv seems to be the most frosty so far

@ 1.4-1.5 kPa I discovered some spider mites, just an extremely small amount. I removed all unnecessary leaves over the last week and increased the humidity and airflow in the tent. Last but not least, I added some predatory mites to ensure the population stays small, likely because my RH was extremely low, in the 40 range.

The plants become surprisingly resinous and have a very pungent odor. The Strawberry Gorilla is already turning purple.

Looking good I can see the lit og genetics in the way the hairs are forming
