Day 36. Still no feed.... Again, difference in size growing many autos is HUGE pain. One Northern Lights is smallest plant I ever grew, I doubt I would I achieved it with loads of LST ;))) Will try to lift that midget a bit ... Some flower, some not, Diesels are still the only strain I would grew, but most probably not once ;))) they look amazing !!! 10 out of 10 ! Green Crack still the obvious looser at the moment and is still mostly in veg ... Next watering will be full of goodies for them !!! Couple leaves off here and there, couple branches cropped or repositioned, still waiting for stretch to be over before installing some support. Day 37. One more girl took SuperCroping like champ and at the moment has very even canopy. All garden looks fine, hope feed won't spoil that joy ;))) Day 40. Girls still on water, but during every two days, so it's again pain ... Whatever pot size I take - girls start to go faster, than my laziness wants :))) Cleared bottoms of first row, next watering will clear other 5, just want to see are they ok. Some strains hates any job done to them and stops developing.... Would be stupid to slow them down in final stretch ... Happy Growing !!!

We reduced light hours from 20h to 18h..I know being this far in flower it sounds idiotic but we're trying to give them more down time to recover because we (well I did lol) burned the ever living crap out of a few of the babies at 18 inches, lesson learned..the SP-3000 is no joke, it's very intense.. we raised the light to 22" as well.. using autoflowers to dial in wasn't one of my brighter ideas but live and learn lol..besides, we have some killer photoperiod strains immediately on deck and this yield is still looking pretty good considering.. everyone is getting a (very) little bit of P,K and cal-mag with every watering..we're also adding a few ml of grow too.. all new growth has a great color...thanks for reading if you chose to do so and happy harvests everyone! ❤️ ⚡Mars Hydro/SP-3000⚡ Specifications ⚙️: Diodes: Samsung LM301B / Osram 660nm (960 total!)

I'd really like to try this strain again now that we've got distance set..despite the mishaps they still look like they'll give up a pretty good yield but I suspect it could of been bigger if we got that week and a half back ,but I can't be upset, at our row of good sized colas that look and smell fabulous! ❤️😽💨 ~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~

Blueberry Muffin – Pheno B | Week 4 Finding Her Own Rhythm Welcome back to another chapter of the 8×8 Adventure, where twelve cultivars are being documented individually from seed to harvest under a strict 12/12-from-seed schedule. Every phenotype follows its own diary, allowing each plant to develop independently and reveal the subtle differences that make every seed a unique expression of its genetics. Week 4 has been another exciting chapter across the entire room. The explosive growth that began last week has continued, and every day the garden feels a little more alive. Canopies are becoming denser, branches are reaching outward with confidence, and the room is slowly transforming into the miniature forest I imagined when this project first began. One thing that couldn’t go unnoticed this week was the environmental reading. 33.3°C and 63% humidity. Apparently the grow room has developed a strange obsession with the number three. 😄 Although temperatures climbed higher than I’d normally like, the relatively high humidity helped soften the impact, and the plants rewarded the stable environment by continuing to grow with impressive vigor. Sometimes nature reminds us that consistency is just as important as chasing perfect numbers. ⸻ Week 4 Environment 🌡️ Temperature: 33.3°C 💧 Relative Humidity: 63% 💡 PPFD: 700–800 µmol/m²/s 🌱 Medium: Plagron Lightmix ? Growing Method: 12/12 From Seed As the room continues to develop, another interesting difference is appearing naturally. The lighting itself hasn’t been increased significantly this week. Instead, some phenotypes are simply growing faster and moving closer to the fixtures. Those taller plants are now receiving around 800 PPFD, while the shorter individuals remain closer to 700 PPFD. It’s another reminder that no two phenotypes read the same instruction manual. Even under identical conditions, every plant follows its own pace. ⸻ Feeding Strategy The feeding program has also continued evolving alongside the plants. During the first weeks the nutrient solution stayed around pH 5.8, maximizing nutrient availability while young root systems became established inside the containers. Now those root systems have expanded considerably, allowing a slight shift in strategy. Throughout this week the solution gradually moved toward pH 6.1, while nutrient strength steadily increased, finishing around EC 1.8. The recipe itself hasn’t changed dramatically. No major adjustments. No sudden jumps. Simply a gentle increase in concentration to match the plants’ increasing appetite. Sometimes the smallest adjustments create the biggest improvements, and this week’s growth has been a great example of that philosophy. Allowing the pH to drift slightly higher also gives the roots access to a broader spectrum of nutrients available within the substrate, helping support the increasing demands of this new stage of growth. As always, the goal remains the same: Listen to the plants, not the feeding chart. ⸻ Blueberry Muffin – Pheno B This young lady has been quietly writing one of my favourite stories inside the tent. Unlike her sister, who seemed determined to impress from almost the very beginning, Pheno B decided to keep everyone guessing. Her first weeks were… let’s call them creative. The leaf structure wasn’t quite what I expected, growth was a little unusual, and every new set of leaves felt like another clue in a mystery I hadn’t solved yet. Fast forward to Week 4… The mystery is starting to make sense. She’s finding her own rhythm. Looking at her now, it’s hard not to appreciate just how much progress she’s made over the course of a single week. The unusual appearance that once caught my attention is fading into the background as healthy, vigorous new growth begins taking over the canopy. She’s still not trying to imitate her sister—and honestly, I hope she never does. Every phenotype deserves to express itself. The structure is becoming noticeably fuller, with side branches beginning to establish themselves beneath the canopy while the main stem continues building upward with confidence. Internodal spacing remains compact, creating a nicely stacked framework that should provide plenty of future flowering sites. One detail I particularly enjoy is the contrast between the older and newer growth. Fresh leaves emerge in a bright lime-green colour full of energy before gradually darkening as they mature, giving the plant a vibrant appearance that changes almost daily. Looking deeper into the canopy, more secondary shoots are beginning to appear than I expected only a week ago. She seems to be quietly building herself from the inside out, strengthening her framework before making any dramatic moves upward. There’s something very satisfying about watching a plant overcome an uncertain beginning. She may not possess the textbook symmetry of Pheno A, but she’s developing a character entirely her own. And sometimes, those are the phenotypes that end up becoming unforgettable. ⸻ Looking Ahead Week 5 should be another exciting milestone. With nutrient demand increasing, root development well established, and the first signs of flowering beginning to appear throughout the room, I’m expecting another noticeable leap in development. Over the coming week I’ll be watching closely for: • Stretch progression as flowering begins. • Continued branch development. • Response to the higher EC. • Structural differences compared to her sister phenotype. • How her unique architecture evolves as the canopy continues to fill. The slow start now feels like a distant memory. This week wasn’t about catching up anymore. It was about proving that she has every intention of writing her own story. ⸻ Thank You A huge thank you to everyone following this 8×8 Adventure and taking the time to visit these weekly updates. Thank you to the entire GrowDiaries community for providing a place where growers from around the world can learn, share experiences, and inspire one another every single day. A special thank you to Plagron for providing the nutrients and cultivation support that keep this project moving forward. Thank you to Zamnesia for the incredible genetics, equipment, and the opportunity to document each phenotype from seed to harvest. And finally, thank you to every grower who leaves a comment, shares advice, asks questions, or simply enjoys following these plants as they write their own stories. Every phenotype has its own personality. Watching those personalities emerge is one of the greatest joys of growing. 🌱💚🍇 Growers Love, and I’ll see you all next week.

Hey everyone! Volume hasn't increased dramatically this week, but trichome production has gone into overdrive. And honestly, that makes me just as happy. Pistils are still almost entirely white, so the colas haven't fully expressed their potential yet. There's more to come. Temperatures hit 31°C during the day and 28-29°C at night, yet the Rainbows have maintained solid vigor throughout. Runoff EC came in only 0.2 points above input, so the nutrient solution stays unchanged. Plants are clearly in a good place. One thought though: could the trichome explosion be a natural defense response to the heat? What do you all think? 🤔 Good luck to everyone and as always critiques and advice are more than welcome! 🙌

These are shooting up now 🚀 I overwatered them last week so waited 5 or 6 days until they felt light and then watered with advanced nutrients voodoo, piranha , tarantula 1ml pl Will be topping some point this week 👌🔥🔥

It’s getting cold and damp. Fingers crossed for a couple warm weeks into croptober

End or transition and ready to bloom!!! Stay tuned this is amaz

Results are starting to come in now, going to be Cake all the way to the end. Time to grab your popcorn and stay tuned in 🤡🎪 Short Phenos is Pure Michigan lean, obvious now with the purple starting to form from bud sites. Tall girl is Sugar Cane Pheno what a stake, huh!? GHL out 🚀

Esta es la segunda semana cambiamos a bases de floración y las chicas se vienen comportante exelente ya han sexado todas. Saludos y buena semana colegas

13 short week cz im on vacation. I got the biggr tent and moved the plants. I then lolippoed them and tied them to the frame of the tent. it's a 2m height and I hope this will fix the issue.

On the final few days of a 10 day flush. Will be chopping down this week to harvest and hang dry. Really excited to try this one. The smells in the room are unreal.

White Widow is coming along nicely. Good bud development this week. She still has several weeks to go. My attic (where my grow tent is) is getting pretty hot these days. I'll probably be moving her outside over the next couple of weeks to avoid heat issues in the tent. Hoping for the best! 🙏

5. Woche Hab sie letzte Woche nomma getoppt und jetzt darf sie sich erstmal bisschen erholen. Update von Tag 40: Topping nr. 4 ist durch und jetzt darf sie sich erstmal erholen 😊

Hello hello! This past week was filled with explosive new growth; these clones certainly live up to the standards set by their mother. So much so, in fact, that I decided to take two more cuttings. We'll see if they root. This will be either the final or the second-to-last week of veg for these plants as they've nearly filled the space completely and are beginning to shoot upwards. A lesson I learned with Carl&UKBS 1 was the "perfect window" of veg time- filling the space and maximizing yield while still allowing airflow to prevent mold. HST and LST will continue into flower, HST will stop at F7. LST will continue until harvest as I'm not scrogging the plants this time around. -9/20- Tomorrow the new week will begin and the clones will be flipped to flower. Wish me luck!

this is my new project :) the balcony is on the north side so it doesn't get much sun :) we'll see how it goes :) good luck to everyone.

This update is dedicated to @greenmachine. Slurricane blast with Butane. Dimonds and sauce. Is there anything more to say? It came out BEAUTIFUL. 🔥💎🔥💎🔥💎😁

Day 91 she’s huge and starting to bulk up. Her green color has returned once I got the ph issue under control I wasn’t sure if it was going to return. She was very sensitive to the water quality. I’m excited to Watch her bulk up she’s a slow finisher for sure. But you can’t rush perfection.
