🌱 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. 🌱💚

Looking good hopefully 🙏 a couple more weeks

Awsome strain from SWEET seeds .🙏🏻❤️ Thank you

She was a bigger stretcher leading into week 4-5 of flower. Definitely need to hunt this cross in the future, insane terps amazing smell overall shes a banger 🍪🔥

May, 18th The last remaining Plant keeps on Budding and smelling Trichomes are mixed, still afew clear,, but alot of milky ones and some amber, too So she gets more Tme to maturate

Blackberry moonrocks the leaves on both the seedlings have a very distinct look definitely different than the average leaf really pointy and 1 of the 2 seedlings sits praying 100% of the day. I think that one is really going to be a winner. Last grow I overwatered and had to toss them because growth got stunted and a bunch if fungus knats got to the soil. This time I'm trying promix potting soil wish I had tried promix hp but the store close by isn't a hudro store and that's what they had. So this time I'm being very cautious with the watering I'm only useing a spray bottle I'm currently giving 45 spray per solo cup every few days when it dries out. This promix soil seems to hold water decent so the 45 spray there is 0 water coming out the bottom the cup yet. Here soon I think I'm going to double the amount of spray to 90 and start letting the soil get dry dry before watering again. Probably will hold off on any nutes quite yet. I'm going from 24/0 to 20/4 light schedule this week. There getting to the point they won't strech as much is 4 hrs of darkness and I'm rasing the light intensity a little it's been around 150 I'm upping it to around 175. Most likely by the end of the week I'll probably be pushing 200 or close. Hopefully I can get them into the big tent soon At this stage I like to alternate having the fan blowing on them I feel it gives them time to recover and get stronger instead of wind stress. Also every few days I will turn the plants so they are facing away from the light making them grow back towards the light I fell it makes them stronger

These are great smellin buds very fruity and very strong. The small one is the smallest out of the whole crop. I'm guessing another week before flush, started bring in ppms down today and lowered my base.

Die Woche war sehr gut nun sind wir fast fertig:)

Well, this is the first one of flora, they already showed some pistils which are the initial sign of flora and so let's move on today I added 1ml of top bloom from top crop and let's see what happens to this grow I still think it will last a few more 8 weeks until the harvest, any questions feel free to ask or help me with something I haven't seen and I'm open to tips too! =D

7eme semaine, it’s tiiiime to fluuuuuuuuuush

Hola chicos subo alegremente mi seguimiento

Sanlight EVO 3-60 at 80% Day 113: looking good and watered again🌊. Watered with rain water, 1 ml/l Cal Mag, and 1 ml/l Green Sensation Day 115: Watered with rain water, 1 ml/l Cal Mag, and 1 ml/l Green Sensation Day 119: looking good 👍🏻 watered with out supplements 👌🏻 Just rain water 👍🏻

01/26 - (Clone mother) - She got a little funky last week and was in recovery mode for about 2 days - She has since then recovered (24hrs) and is performing amazingly - Running high temps High humidity - 2 part feed (Clean/Nute) on micro-dose program. 01/31 - Applied HST to lay her out - she is rebounding accordingly - Increased her feeds to once every other day alternating from nute to clean water - picked up the lights a little (19 inches above canopy) to clear room for SOG

Notong to go now looking good swelling into nice solid nugs citrus aroma coming off of them

Follow my grow to see full grow cycle. Happy with what I learned during this run. Only going to get better and better!

Outdoor coco 15g pots Progress: Lava cake is about week 6.5. Starting to ripen and get heavy. Buds are getting fat. Strong sweet cookie/ ice cream smell. Buds are getting more frosty. Buds are getting so heavy I installed a net on 3 of 4 and doing #4 soon. On my most mature plant - About 25-30% of pistils have turned color. Some trichomes are milky, none amber. Looks like plants are a few days apart. Marathon OG week 5 1/2. Still stacking and getting fat. Smells dank. Trichomes are showing up. The 20 gallon OG is growing into a monster. I’m still waiting for the heavy bud stacks…. Nutes: Bumping up ppm, the dry koolbloom and molasses, stopping regular koolbloom and grow. Looking to starting flushing the lava cake in a week or so. Feeding 2x a day; 3x on hot days. Weather: Had a good week of cooler temps until yesterday, when it was 97. Looking at hugs in the 80s this week, perfect. Pests: The moths and caterpillars are in full swing so I’m applying BT every morning. I’m working hard to reduce caterpillar 🐛 losses. We lost all of the top colas on a plant in another location 💔 . I’m only losing one bud at a time and not the entire colas so far. Wishing fat buds and monster harvests to all.
