🌱 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. 🌱💚

Привет садоводы ! Растения растут потихоньку , развиваются

12cm vertical growth but look how bushy she is! Not quite entered flowering yet, but that's good... More veg time = bigger plant 😍

Wanted to flip but thought I might had pest

Wow! Hard to believe these are autoflowers, I’ve never harvested a cola off an autoflower quite this robust. The hps lights in the 2nd grow room were maybe a bit much and all the plants handled it differently. The big beast is one that did very nicely under the hps lights. The smaller much more frostier dried bud is from the mars hydro ts1000 grow tent. Not nearly the yield or density but beautiful crystal covering the buds. Amazing colour from both the led grow dark devils and the hps ones.

This is the Biggest/Best cannabis plant on GD with a 4 week veg from seed?

Day 122 / Week 7 of Flo: Since the colour of the fanleaves is fading away pretty quickly, i decided to add in a little nitrogen (in form of BioGrow). I havent been feeding any nitrogen since the beginning of the 5th Week of Flowering. Only the little that is in BioBloom, that is only 2% The complete solution i used is following: 16l Water (4 each plant) 8ml Bio Grow 48 ml Bio Bloom 16ml TopMax 48ml BioHeaven 48ml ActiVera Day 125 / Week 7 of Flo: I am not adding any more nutrients at this stage and i started watering every plant with 2,5l of water every two days as their demand is not that high anymore and i wanna keep humidity down to a minimum to prevent bud rot. To give you an idea in early Flowering i was watering every plant with 5-6l every 3 day's, from 5th week on i was giving them 4l every 3 days and now only 2,5l. As two of the plants (Plant #2 and Plant #4) are starting to look like they are close (about 10-12 days) to harvest i am considering to flush them one of the next days. The other two plants (Plant #1 and Plant #3) seem to be of the same phenotype and look like they can take a few days more, let's see.. Also they grew bigger and stretched more in flowering then the other two, maybe a little more sativa genes.. Day 127 / Week 7 of Flowering: Today i flushed plant #2 (back left) and plant #4 (front right) with 20l of fresh water 💦 from the well. Plants #1 and #3 are recieving 2,5l of plain water every second day for a few more days. Soon i will flush them too.

End of week 4 is here, I made some cuts of leaves and lower branches. I did the tying of twigs and start adding Bio Heaven. They should be start flowering next week, everything going good. I added exhaust fan, coz they are sweating at night too much. So there are Profan 40watt and monkey fan (16watt) that goes non-stop. Oh and Amnesia 3 start showing stigmats this week. See ya next wednesday

Hello to you my dear friends and visitors👋 I transplanted the plant to a bigger rockwool cube on the fifth of september and added some veg nutrients...on September 10th i transplanted the Blue Cheese Auto seedling into a golden cheese grater, that i thought would be my idea for the Tiny Pop competition organized by Seedsman®️ Wish me luck 😊 The bright and lovely TS 1000 lamp from Mars Hydro is set at 55% of power is using about 65 Watt and is hanging at the height of 30cm as the manufacturer recommends. All the best to my fellow growers and friends, keep it growing friends 💪

I would give this strain an average rating. Nothing great nor bad. I have had both better and worse strains.

15 Noviembre: -Hoy se instaló el sistema de riego "Drip to Waste" que me permitirá hacer riego de precisión, con protocolo "Crop Steering". -Se instalaron sensores de humedad de suelo, para saber cuándo y cuánto regar, el sistema manda datos de humedad de suelo, temperatura y humedad ambiente, etc vía internet a mi celular. -Mañana se comienza con el primer riego de precisión. 17 Noviembre: Segundo día de riego automático, 3.0EC y 5.9pH, las plantas crecen a buen ritmo, las raíces ya están saliendo por los orificios de drenaje a 2 días de transplantadas. 20 Noviembre: Se realizó una pequeña defoliacion de las hojas tipo abanico muy grandes.

11/15 Coming along but not without problems. 3+ weeks in now I'm in the stage where I'm just trying to push all the right buttons and guide it to harvest. They've all demonstrated some level stress but bud formation is coming along well. I dont know if I'm just used to the smell but it hasn't really gotten much stronger. I'll try to take some more pics later on. The past week has been a little busy.

2 weeks of flowering (currently 12.5h light) are done and the plants are doing well! I have upgraded the grow box a bit, I now have a TAPO sensor for humidity and temperature that automatically turns off/on the ventilation system Tomorrow the automatic watering system will be installed, more pictures will follow. Update: Watering system added, took me quite some time to install but figured out how I can make each plant get the same amount of water. It is a cheap wifi system from Aliexpress, 25€.

This plant has been very enjoyable to grow and the smell of it is incredibly Pleasant I will update when the plants are drying and ready for curing it will take approximately between 7 and 14 days because I wait until the main stem snaps with a crunchy sound. Day 5 of drying and they are still far away from ready but they're starting to show a nice Colours now . the smell it's becoming very powerful even without curing I know many Growers cut them down when the smaller branch are snapping off easy but I wait until the main stem I bend and a crunch very dry sound come out of it because I don't like to deal with mold and I have a very busy life can be opening curing jars every few hours everyday that's why a good Boveda packs and a good drying are my best friends. These are the weights for the two plants that one that was bigger #1 is 51.12 grams the second plant #2 was 36.17 grams . They smell very nice like a kiwi skunk smell to it . The high are strong and last about hour and a half to two hours. For a regular smoker I will classified as day stuff on the Stoney side. With a high THC probably what is advertised on their website . This is very good for somebody who wants to have a quick grow of very good stuff or somebody who lacks space but doesn't want to sacrifice quality. The fact that I couldn't get a large yield out of it was a bomber for me I really like plants that are capable of producing a large yield. Taste 10 out of 10 Aroma 10 out of 10 High 8 out of 10 . day. strong THC. Yield 6 out of 10. Easy to grow strain. Possible to crop in 65 days from seed at 20h lights on.32 Centigrades and 45%humidity. Thank you for reading I will continue to update have a happy grow.

she got burned aboutthe bloom simulator excess.

13 hours and 33 minutes of daylight when I took these photos and this video on August 27th. I've been slacking this month on uploading, having to play catch-up with this just like everything else in my life. I'm so glad it's going to be September in a couple days. The weather is cooling off thankfully🙏 So, I cover most of the situation in the video, but basically GG (Good Girl) is looking great and her flowers are coming along nicely, whereas PC (Problem Child) is still continuing to be a Problem. Child. First of all, PC is a much heavier feeder than GG. I have to give her almost 2x as much food as I give the other plants for her to have the same color. And since I've been running around all August and haven't had much time to tend to my beauties, I haven't been feeding as much as I could have. The other photoperiods are fine, They're still getting nutes from the soil and hopefully the mycelium from the substrate blocks have moved into the root system and are acting like good roommates and doing their part to support the soil foodweb. But this isn't enough for PC. Her flower development is definitely behind and her color is a brighter green than the other plants. Hopefully I'll have time this month to just put the groceries to her and encourage those flowers to bloom because now I'm worried about the frost that will start coming in early October. Frost and ripe trichomes don't mix very well. My apologies for repeating myself in the video😬
