I haven't used anything but water, they are in my green house with at least 8-9 of sun. What do you think?

Hello we are in the nine 'th week. She is healthy and growing good buds. 24.11. Day of life 64 flower 26. Smell is earthy than orange and... 😛 And.. And... .. YEAH I see bud's coming. Lot of them... With these smell. This would be heaven for everyone. This smell is so fresh, this smell is so Nice THIS WOULD,BE HEA... forget any association. LOL (no fxxking emotes. Im from c 4(lol) NINTENDO.) @ XXXXXXX Original. Friends sometimes looked @ me with wide open eyes and calle me testicle rat,! Its an honor! because it's not easy too mess in my mischievous way. Normally nobody is hurt in my jokes, and we laugh together. ANNNNND Not HALFTIME.. of flower.. Max 56days says LINDA SEEDS.. This would be QUICK This would be nice.. THIS WOULD BE HEA.. ÄHMM koff. Ähmm. Ja. ... 29.11. Today i saw snow... Behind the window. Day 69 of life. Flower 31. Of max 56..😛 💪 Min 42.. Grrr aphids.. Wait. This week will be the last for them. Biologycal weapon is coming for you... 30.11. Today i used a B weapon thurigensis bacillus. The problem... I hate aphids and i got some more guests.... Let's see un the days how it works. I sprayed the water bacilus emulsion over all my tent.

expect high super high levels of frost , be sure to start your training early on this plant and defoliation of lower growth will help out a lot, with care you can have beautifull massive grapewalker kush's glad ivesaved some for the vault , thanks for sticking around for this journey now for the next =)0

I'm switching to 18/6 now and continue to feed them small amounts of growzymes by green buzz nutrients in distilled water which I think they like. The LSD-Auto is finally starting to gain some pace and grows just as fast as the runtz muffin. I consider transplanting them at the end of the week so I hope for more good growth. Update: It's the end of day 9 and I decided to transplant. I expect faster growth now because I think the baby pots already slowed them down a little bit. Update: Day 12 and they look amazing! Now they start to grow really fast. They look healthy and I will start with training soon. If You have any tipps or experience to share please drop it down below💚

So you've grown a normal seed? so you've grown and autoflower? well why don't you try the fast streams definitely one of the most interesting and exciting grow experiences I have been a part of up-to-date. One of the most notable traits was the branches being extremely susceptible to bending making it a truly ideal strain for a SCROG. I think one of my main mistakes was leaving the plants in a 3 gallon pot I would suggest that nothing less than a 5 gallon pot should be used and from what I have seen going from jiffy transplanting into a Solo cup then solo cup straight into a 5 gallon pot has worked much better for the clone run I'm doing now. These plants need support!!! That is a must! Especially if you are going to use defoliation at any point you're gonna see a mass of spurt of growth. Now another thing I noticed is that the end right towards your finish window where your trichome are going from clear to Cloudy They tend to mature a little bit faster than a normal photo sensitive Strain. On the feedings I would do at the end 75 to 80% of the recommended maximum nutrient mixture you are using meaning use a little bit less the nutrients for the green crack. Expect A flowering stretch of at least 75%. Other than that I'm extremely impressed with the genetics again that humbled seed organization has created for us cannabis lovers to Excite and motivate us to have something different.

2/19 Week 8 Controlling the stretch somewhat by keeping strong blue light in the spectrum. Wont start flower under HPS again, will wait till stretch has finished. The FFt-7 seem to respond most to this, the FFt-5 not as much but still slowed down. Major day coming Saturday everyone back into one tent and that undergrowth is getting trimmed! Driving me nuts Wont need to worry so much over height at that point. Adding that small amount of PK has really spurred a lot of bud growth, looks like the guys knew what he was talking about. 2/21 Could not wait so... Lower End Defoliation Day! Cleaned them all up for their last day in Moya (veg tent) before moving to Enterprise (Flower tent) ... heh Walking nuets up 2/22 in the new digs Both the 600w HID and 150w LED are now in the tent = 750w Everybody is on the Enterprise now. 2/23 white tips back dropping back down to 4ml/gal on the CT 2/25 Cutting back PK to 2ml/gal Pics for Fast Buds on leaf oddity Raised HID a couple of clicks getting some praying leaves underneath it.

Our Zamnesia Critical Cheese Automatic has a distinct, predominantly sativa appearance. What a plant guys, I cleaned the ugly flowers very very well and I can really say that I am very happy with this plant. Swollen buds, well aligned and looks super healthy, can't wait to smoke this. Techniques chosen: Here, we applied LST to a plant with short internodal spacing; it's not ideal, but we wanted to give it a try. We're 100% organic and 1000% Plagron, as always. The soil we've chosen is the recently released Plagron Bio LightMix, which will allow us to start flowering more smoothly and reliably, without the sudden changes that liquid fertilizers can cause. A week is more than enough, so don't overdo it. We're in the final flowering stage and things are starting to get serious, so we're adding our legendary bloom booster Green Sensation and starting the late flowering phase. - Green Sensation 1 ml/l - Pure Zym 1 ml/l - Silic Rock 1 ml/l - CalMag Pro 1 ml/l - Sugar Royal 1 ml/l - Power Buds 1 ml/l - Alga Bloom 0 ml/l Just booster and soon in flush Choose your preferred style and calculate your results on the website: www.plagron.com Z - https://www.zamnesia.io/it/531-growshop A great strain, not tall but very bushy! Give it a try! Z - https://www.zamnesia.io/en/3334-zamnesia-seeds-critical-cheese-automatic-feminized.html Z - Not content with what they already had in their hands, the expert breeders at Zamnesia Seeds wanted to embark on a journey into the world of autoflowering genetics, aiming to improve upon a great British classic... the Cheese cannabis strain. They crossed Critical with a high-quality Cheese specimen, enriched with a significant amount of Ruderalis. The result is an extremely potent, therapeutic, and easy-to-grow autoflowering version. This new, improved strain has been named Critical Cheese Automatic. Critical Cheese Automatic embodies everything that made the original Cheese so famous, acclaimed, and loved around the world. We're, of course, talking about the Skunky flavors and pungent aromas this strain releases, not to mention the overwhelming effects it induces. Lovers of the original Cheese will surely appreciate this feminized reincarnation. Smoking Critical Cheese Automatic produces exceptionally potent sensations for an autoflowering strain. Its effects are quite strong and highly physical, both in intensity and duration. With these properties (or "body") in mind, it's no wonder many medical users are the first to want to get their hands on this "skunky" plant. Those suffering from chronic pain, inflammation, stress, anxiety, and migraines (to name just a few of the ailments it can alleviate) will notice their symptoms diminish, if not disappear completely, thanks to the potency of this strain. With this autoflowering "upgrade" of the Cheese strain, even novice growers can achieve excellent results. It's a vigorous plant, incredibly easy to grow, and requires little maintenance. Commercial growers looking to generate income will appreciate Critical Cheese Automatic primarily for its life cycle: from germination to harvest in just 10 weeks. When grown properly, it can produce yields of 120-150g per plant. In addition to its excellent yields, Critical Cheese Automatic reaches a rather compact size (1 m), making it highly suitable for any type of grow. That said, Critical Cheese Automatic only thrives when grown outdoors in warm climates (like those of Spain or Italy). So, in conclusion, whether you're a beginner, veteran, or commercial grower, Critical Cheese Automatic offers great satisfaction to everyone. You know it, but I recommend it: here you'll find so many beautiful things, basically "all the best that nature has to offer."

Hello Guys and Happy Easter🐰, Week 4 of flowering is over. One plant got a polyploid mutation i got the same mutation on an earlier grow so i know this will look interessting at the end. I did my first cuttings on the Slurricanes 8/10 are rooted so im quite happy with the outcome but unfortunately the cutting from the frostiest pheno at the moment didnt make it. I did a little bit to much on the more PK nutrients so they got a little bit buned tips but in overall im very happy some of the plants already smell so fruity and sweet cant wait how this Tent will smell at the End 😋

Started training

Harvest: Everything dried up to 347 grams + 96 grams of super high quality trim. Overall I am not too pleased with the smoke of the product. Although the bud size, bag appeal, smell and taste are pretty much all there, the shitty burn is a deal breaker for me and the majority of this weed is quite frankly useless. Another downside is while smoking I’ve found 4 seeds in an ounce from almost every strain. Light leaks? At least I learned a ton, including how to get super good burn for my next crop. I’m hoping that curing for a month or so will improve the burn but I wouldn’t really count on it. I have seen weed dried for 4 days with no cure and no flush smoke clean and not go out once. I have been told that the key to white ashes/clean burn is proper mineral content in the soil and there is tons of scientific studies on cigar ash going back 100 years. Plants grown in a medium with high levels of decomposing organic matter, phosphorus, magnesium, chlorine and heavy metal ratio tend to produce black/grey ash. Whereas plants grown in a medium with a higher ratio of trace minerals like calcium carbonate and potassium in the form of wood ash, rock dusts, oyster shell flour and lower levels of decomposing organic matter will produce a dense, uniform white ash that rarely goes out. But this is still all theory until I test it to confirm for myself a few times. My last few outdoor harvests did not improve with curing at all so I’m hoping this will be the missing link. Plain peat moss and coco clearly lack essential minerals that help burn. If said theory is correct I should find a synthetic nutrient line with more trace minerals. Makes me wonder if growing if rockwool/basalt rock could improve burn in a hydro setup. I think I did a fairly decent job for my first grow. I went wrong in a million different places but I still stuck it out and got some decent herb. Things went wrong early when I got black spot mold, nitrogen/magnesium deficiencies and powdery mildew. I corrected most of it but things didn’t get really bad until mid veg when I intentionally skipped a few feedings and defoliated quite heavily stunting the plants. I also didn’t even top or start LST until the 6-9th node which was really stupid and hurt my yield. My temperatures were all over the place from the learning curve. I was severely overwatering without realizing it. 100% peat moss is a shitty medium. I also fed way too late in flower (not what caused shitty burn). I also used synthetic nutrients in soil.

She is stacking up…I will defoliate her this week and increase the feeding of bloom as a test to confirm how much she can handle.

24.06.26 Läuft sind gut gewachsen in der letzten Woche 25.06.26 Läuft der Sommer ist da 30°C am Wochenende sollen es 37°C werden. Hab noch ein paar Äste an Sour Diesel, Chocobang, Apple Betty und Skunk Haze entfernt die nur Energie klauen. Und sie trinken im mom echt viel 2 Eimer und 2x 2L Flaschen mit Dünger täglich keine Ahnung wie viel das ist so 20L oder mehr auf alle verteilt 26.06.26 Heiß!!! 27.06.26 Läuft heute gab es ein bisschen Epsonsalz und Kelp im Giesswasser soll bei Stress helfen bei den Temperaturen die uns bevor stehen 28.06.26 Es ist heiß gab starke Gewitter 29.06.26 Läuft heute gab es ein bisschen FischMix so ~4ml auf 2L Wasser verteilt auf alle Pflanzen nur um das Bodenleben zu unterstützen da die immer noch nicht so wirklich Futter brauchen mal schauen wie das in der blühte wird. Es ist auch wieder etwas kälter geworden und regnet

Buds are getting denser, stickier and stinkier this week. Defoliated a few leaves from each plant throughout the week. Watered every 2 days with a 1/4 gallon to each. They got a mild compost tea beginning of the week to boost the microbial life and their final top dress towards the end of the week.

She's done! I'm seeing plenty of amber trichomes now. Harvesting in progress.

We are going to put the smaller clones higher (on a table or whatever) and soon we will start to flower, i would have flowered earlier but these girls are sharing room with other plants

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.

🌱 GMO Cookies — Week 5 (12/12 From Seed) Late Veg / Pre-Flower Transition General Vibe The girls are feeling amazing this week — calmly exploding, super elegant, and bushing up beautifully. Structure is compact yet full, with a very balanced expression across the canopy. No rush, no stress — just plants doing plant things. Training & Structure We’re continuing with very gentle LST — mostly bending and positioning leaves rather than aggressive branch work. The goal is simple: • Open light pathways • Encourage lateral growth • Let the plants decide their final shape They’re responding incredibly well: tight internodes, bushy profiles, and strong posture. You can clearly see the progression in the photos from the beginning to the end of the week. Growth Stage Observation By the end of this week, we’re starting to see early pre-flower signs. Nothing dramatic yet, but the transition is clearly beginning. ➡️ Next week’s update should start showing more defined flower development. ⸻ 💧 Nutrition & Water Strategy This week we introduced CalMag Pro — not because the plants are asking for it, but as a proactive step heading into flower. Why now? • We’re using collected rainwater + dehumidifier water, which is extremely soft • Before stacking base nutrients and supplements, we need to build a proper mineral foundation • This ensures stability and availability later, especially during stretch and early flower demand This is preparation, not correction. Autopot Zone We’re running two feeding zones in the tent (6 plants total), which is why you’ll see different measurements in the diary photos: • Autopot zone: mineral-based recipe only • EC: 2.29 • pH: 6.0 • (Organics don’t play well with Autopots — keeping it clean and stable) • Solution temperature: ~22–23°C across both zones • Slightly warmer on purpose to support root activity during colder weather ⸻ 🌡️ Environment • Humidity: ~58% • Temperature: ~21°C Outside conditions have been tough this week (4–5°C with 90–98% humidity), so honestly, we’re happy with how stable the room is holding. More importantly, the plants are reacting calmly and positively, which always matters more than chasing textbook numbers. CO₂ remains unchanged at ~666 ppm — steady and sufficient for this stage. We’ll reassess during flower. ⸻ 💡 Lighting & PPFD • Top light: 100% • PPFD: ~700–850 (depending on plant size) The girls are praying to the light — no pushing, no forcing. We let them grow how they want to grow. Under-Canopy Lighting (LumiFlora) By the end of this week, we’re turning on the under-canopy lighting for the first time. Why now? • Plants have grown past the fixtures • It’s time for them to start recognizing photons from all directions • This prepares lower growth for the coming stretch and flower set We’re starting very gently at ~30% power, then increasing slowly based on plant response. No shock, no rush — just layered light introduced with intention. Huge thanks to LumiFlora for supporting this phase with under-canopy lighting. ⸻ 🔁 Quick Recap (For Newcomers) • 12/12 from seed • Gentle, observation-first approach • No aggressive training or forcing • Focus on structure, balance, and plant response • Slow, intentional buildup heading into flower You can jump in right here and be fully up to speed. ⸻ What to Expect Next Week Expect: • Clearer pre-flowers • Stretch beginning to express • Training adjustments as structure reveals itself Don’t expect: • Heavy defoliation • Sudden pushes or drastic changes • Forcing the plants into anything they’re not ready for We observe, adapt, and respond — always. ⸻ 🙏 Thanks Massive thanks to everyone following along, sharing energy, and supporting the diary — and welcome to everyone new joining the journey. As always: Growers helping growers. Trust the plant. Trust the process.

With true love comes happiness. Always believe in yourself, and always do things expecting nothing and with an open heart. Be a giver, and the universe will give back in ways you could never imagine. 💚 Growers love to all 💚 📸 P.S. – The Eye Behind the Lens All photos in this diary (for now — except for the ones showing the camera, which I took with an iPhone) are taken with a Sony A6700 paired with a Sony full-frame macro lens and a few more. Photography is part of the story — it’s how we share the fine textures, the glow, and the quiet details that words can’t always capture. I’ve also started experimenting with photo stacking — a technique where multiple images, each taken at a slightly different focus point, are layered together to create one perfectly sharp image from front to back. It’s not digital enhancement or AI; it’s pure photography — a way to reveal the plant’s beauty in microscopic depth, from trichome to petal. You’ll even see a few shots of "ghost me" capturing the shots — camera, lens, setup — because every grow deserves not just to be cultivated, but documented like art.
