On Day 127 i harvested a few buds from the right plant because she had perfekt condicioned trichomes and a lot from the left because i dont want to risk more mold.

Hello colleagues! ✋😃 Flowering is in full swing, and the left plant, which was slightly lagging behind, finally stopped, almost resting against the lamp. As bro correctly noted in the comment, the plants turned out to be quite large (once again I regret that I did not have time to test them outdoors). The buds are starting to form, I hope that the final part of the cycle will pass approx. Thank you for stopping by, and be healthy! 🙏 To be continued... 😶

Today I watered her with 1.5g de-chlorinated water with 5ml/g of Botanicare CalMag+ added, then ph'd to 6.2 @ 72℉. I turned her pot and plucked a couple of yellow shade leaves...the basic daily maintenance. 9/22- I didn't water her yesterday as she looked great and was 'praying' hard. Today she was given 1.5g of de-chlorinated water which was ph'd to 6.2 @ 72℉ which I gave her through her drip pan (bottom chuggin) and I also gave her pot a turn. She continues to pile on the trichomes and is developing exquisite reddish purple hairs in her flowers that look absolutely wicked! She is definitely one of the most photogenic cultivar's I've grown and is looking lovelier by the day! 😍 9/24- We're getting close to wrapping up Week Six of flower in a couple of days, which will put her around two or three more weeks from finishing, with the most exciting weeks yet to come! I didn't water yesterday and today I went ahead and Top Dressed her with 2 tbsp/g Dr. Earth Flower Girl 3-9-4, 1 tbsp/g Dr. Earth Gold Premium 4-4-4, 1/2 cup Down To Earth Bio-Fish, 1/3 cup Down To Earth High Phosphorus Bat Guano and 2 cups of Worm Castings. I watered in the Top Dress with 1.5g of de-chlorinated water which was ph'd to 6.2 @ 72℉ and let her enjoy her meal! 😜 9/26- After her heavy watering on the 24th I didn't water yesterday and when I checked her today at 'lights on' and she still had some weight to her pot and her leaves were praying hard so I held off on watering today and will hit her tomorrow with her usual 1.5g watering. ~Thanks for stopping in! Things should be getting a lot more interesting in the coming weeks...Stay lifted and be Blessed! 😎🙏~

Day 12F-19F (May 3rd - May 10th) (Day 13) Pots are still super heavy and I don’t see these things drying out anytime soon so we’ll see over the next few days. Still no signs of overwatering. (Day 14) I’m going to do a little lst. Better late than never and since the pots are saturated the stems are bendier. I noticed they were quite droopy during lights off but are praying by lights on. (Day 16) Man these things are filling out slow. I’m going to drop the light a few inches and see if that helps at all. Definitely no early trichs. (Day 19) So I haven’t had to water at all in the last 10 days and the pots are still quite heavy. Oddly enough, I still see no signs of overwatering. Perlite did it’s job I guess.

Gave her water last night and plan for shut her down sometime this week. Today is day 84 from when she sprouted.

🌸 Week 7 Flower – The Calm Before the Harvest And here we are — week seven of flower, and what a journey it has been. From the very first drops of water on tiny seeds to these full, mature blossoms now bowing under their own weight — the Gelonade girls have written their own story in green and gold. Both phenos, #1 and #2, are stunning. Pheno #2, the unicorn with her foxtailing beauty, continues to fascinate — those whimsical towers of calyxes spiraling like dreams reaching for the light. Pheno #1, elegant and balanced, stands beside her sister with a classic structure, both radiating health and character. Together they show us two faces of the same soul — different yet equally divine. 💧 Now It’s Just Water This week, the feeding bottles rest. No more nutrients, no boosters, no extras — just pure water. This is the flush, the gentle cleansing before harvest. By giving only water, we let the plants draw on their reserves, enhancing smoothness, flavor, and the purity of the final smoke. It’s a closing ritual — a moment of reflection and respect for everything these plants have given. 🌱 Quick Recap – From Seed to This Moment • Germination began with The Cannakan method — simple, precise, full of hope. • Vegetative growth brought vigor, beautiful branching, and the discovery of the now-legendary funky leaf mutation. • Transplant into the 11L Amnesia fabric pots gave them the space to breathe and thrive. • Flowering came like a symphony — weeks of stretch, light, and color; a perfect balance of Aptus and Plagron nutrition; canopy lights dancing from above and below. • Foxtailing appeared on Pheno #2, transforming her into a work of art, a living sculpture of what happens when genetics, environment, and light decide to play together. Now, the flowers are glistening — pistils curling, trichomes milky, the scent rich and intoxicating. They are close… very close. Maybe not quite harvest yet, but whispering that they’re ready to show us their final act. 🌿 What to Expect Next In the coming days, we’ll watch for trichomes turning amber, for the pistils darkening, and for that subtle shift in the aroma that says “it’s time.” Expect colors to deepen, aromas to intensify, and the garden to take on that unmistakable aura of readiness. What not to expect? Rush. The girls have given us everything — now we simply wait, watch, and let them finish in peace. 💚 Gratitude To the community, the growers, the dreamers, the quiet watchers — thank you. To the sponsors and creators who make the gear that lets us grow — thank you. To the lovers and the haters — thank you too; you both push us to evolve. And to the Gelonades — thank you for being the living proof that care, patience, and love can create art from soil and light. 🌸 Closing Thought This week feels like the pause between heartbeats — the silence before the song’s last note. Everything we’ve done led us here, and everything that comes next will bloom from this moment. “May the waters run pure, may the buds rest easy, and may we harvest not just flowers — but gratitude for every step that brought us here.” 📝 PS: Pre-Harvest Notes — Knowing When It’s Time The last stretch before harvest is all about observation and patience. Every grower wants to pick the perfect moment, but that moment is a whisper, not a shout. Here’s how to listen for it: 🌼 Trichomes Your best guide. Under magnification, they tell the story. When most are cloudy with a few amber heads starting to appear, the flowers are at their peak — full potency and rich aroma. Clear trichomes mean “not yet,” while too many ambers mean the effect will lean heavier and more sedative. 🧡 Pistils Watch the hairs. Early in flower they stand white and proud, but as harvest nears they curl in and darken to orange or brown. When roughly 70–90% have changed color, the plant is signalling readiness. 🍃 Leaf Fade As you feed only water, the large fan leaves begin to pale, pulling the last stored nutrients into the buds. This is a natural and healthy fade, not a deficiency — it means the plant is completing her life cycle. 💨 Aroma Shift In the final days, the scent deepens — less sweet, more complex. Sometimes you’ll notice earthy, gassy, or fruity tones becoming more defined. That change means the terpenes are reaching full maturity. 🌙 Energy Even the way the plant feels changes — the branches seem to relax, the weight of the flowers makes them bow slightly, as if in quiet surrender to the harvest. When all these signs align — trichomes milky with a touch of amber, pistils mostly curled and dark, the fade in motion, and the room filled with a full, mature scent — then it’s time. Until then, let her dream a little longer. The last few days often bring the biggest magic. ✨ 📲 Don’t forget to Subscribe and follow me on Instagram and YouTube @DogDoctorOfficial for exclusive content, real-time updates, and behind-the-scenes magic.

From my first grow using a LED 300w light I bought of eBay I have moved on to a indoor tent for my second grow with a 600w HPS set up as I found that the LED light possibly due to its low build quiality was not producing enough light for the buds to reach there maximum potential. After a week from planting the seed I moved them from under the LED into the tent to let them do they’re thing.

Day 43 let's start week 7! the plants grow and continue to stretch. unfortunately two weeks ago my ph meter broke. last week I started giving 1ml / l of green sensation and the plants seem to have lightened a lot. these days i should have the ph meter back so i can check. all in all they seem to grow well apart from this "yellowing". Day 44 the pH pen arrived and I discovered the cause of the yellowing. the ph was about 5 😭😭😭 now I let it dry well and brought the ph back to 6.7 and given 0.5 l and I wait for it to dry again keep following me to see my progress. it is my first growth and I make many mistakes, leave a like and give me an opinion or advice to improve. good luck and happy day!🌱💚

Well most of them are sick,, some have lost or never had many pistils. It starts to smell a bit now. I still don't know how to deal with collective flushing and harvesting early rippen flowers. Found out the roots were badly burnt,(no slime or foam): 3 of them lost the roots beneath the pot, Jah only knows the state the roots are in. Hoping they won't die before harvest...

🌅💪🏝️💚🔝

8/28/2022 - 21 days since my little girl sprouted from seeds🌱 The third week of vegetation of my Bruce Lemon Diesel 🍋⛽🌻 Nutrients: Jungle Indabox - I had to adjust the dosage, after the first dose of nutrients, the lower leaves of the plant lightened a bit, this was especially visible on her sister Orange Sherbet Auto, which burned the tips of the lower leaves - after this week I reduced the dose by half 🍃🍃 Hesi: Hesi Root Complex I give this root stimulator for root support, although Jungle Indabox also supports root growth, namely: Jungle Urban A - (N-P-K) - (2-1-6) Everything for healthy growth and formation of the root system Atami - ATA Calmag - I missed completely Advanced Nutrients - Bud Candy - I also adjusted the dosage by half 🍬🍬 Preflowering: Classic white hairs appeared on the stem this week, indicating the female gender 👩‍🌾👧🏼 Light: Mars Hydro TS1000 - really great lamp with sufficient lighting and energy-friendly 💡💡 Training: Topping: I usually top in the third week of the plant's life, just like this time. However, now the girls are very advanced in growth, so they will have more main branches 🌴🌴 LST: Two days after topping, I anchored the lowest branches to the ground with metal clips, tied the higher branches with a string towards the edges of the flower pot, so that the light would shine on each of them 💡💡 Defoliation: In the next two days, I cut off all the large leaves that were shading the branches 🌞🌞 The girl is no longer a child, she is a strong young lady, full of branches and leaves. Its color has also changed, it is now deep green again. The stem is rough, so I assume a strong root system 🌲🌴🌾 Thanks for the likes and you can follow me on Twitter 🐦: @ Targona666 See you soon 😍

This strain has been easy to grow from the start and very quickly packed the weight on during flower, for a free seed I'm more than happy with the outcome, if you're gonna grow it give it a good 13 to 14 weeks It's quite an uplifting smoke a nice head stone

Que pasa familia, última semana de floración de esta farm cheese de genofarm, y que decir, es increíble vaya aroma y vaya flores repletas de tricomas. Lleva su limpieza de raíces ,después se controló ph temperatura y humedad todo el cultivo, de principio a fin. Variedad de 10 para trabajar en indoor, ideal para SOG .

9/26 This fucking sucks. Site won't let me upload pictures. Flood warning in effect. I believe this is the fifth day of rain. Not trickles. Sheet rain and high winds. My dream catchers have been taking this like a champ. Ice cream cake was totally sideways for awhile despite vertical trellis. I came down this morning to branches bent at 90° angles. I could've taken them but if I make it through this rain today it's supposed to stop tonight. Then I'll have a week of good weather. Buds are exploding. Even the ice cream cake. That will need more time but I'm getting close with the others. They are never out of sight. I'm surprised they've held up so well so far. I made my decision it would be stupid to alter it now, seeing how the storm is ending. I was going to spray k bicarb but I'll wait until after this rain.UPDATE: Went back over and the garden was flooded. I needed to put one grow bag on top of another as one plant was in six inches of water. I drained it and added supports and pulled off any dead leaves. I tried taking a video but it was raining so hard it stopped after 7 secs. Luckily my dreamcatchers are strong AF. Took to little ones and put them under the barn under a light. It's FINALLY stopped raining. After I smoke I gotta go back over and shake buds again and check for rot. Luckily nothing was broken but it was hanging right down. Fucking sucks. Spent like two hours in sheet rain. UPDATE: Stopped raining. I went over and continued to defoliate and cut little bits of rot from the interior. Sprayed a gallon of potassium bicarbonate and dawn on ever spot of rot I could find. I've been to the patch multiple times today. Found a few earwigs. I think I've found my problem. Late stage leaf septoria with earwigs eating the rotting plant matter. Fucking sucks but at least I have an idea. Can't upload pics and phone wouldn't even work in the rain. One 7 second video. 9/27 The extra work I've been putting in has certainly helped. I got in touch with a company who will do any type of extraction I want for $200 a lb. Fucking awesome. My cousin got 250 grams love rosin last year with this same company. I am sore. I checked trichs but I'm not seeing much Amber yet. Buds are gaining density fast. At least now that I have an idea what my problem is I can address it. Plants showed signs of pm after drying out. I did a k bicarb spray and this morning there isn't a spot. I need to take care of what's hanging so that's the plan today. 9/28 I think I made the right decision.my plants are looking good. Not where I want them but it's getting close. I checked the trichs this morning. Under 24 hour surveillance till harvest. Well it has been but now I stay up every nigh watching the cctv. Went down in the middle of the night to check for nocturnal bugs. Didn't find any. I've been defoliating the yellow septoria leaves. I went through every plant and cut out any rot and removed andy sugar leaves that started to turn brown. This and the k bicarb seem to help. I think that Leaf septoria has dwarfed the growth of the smaller dream catcher. Buds don't seem to be growing much more. Even my ICC has buds almost the size of the little one. The other dreamcatcher will probably be an elbow plant. The ice cream cake has beefed up incredibly and is covered in trich's. I'm super excited but I'm cautious at the same time. I hate that fucking dog but it's an added layer of security. Soon I'll do the harvest report for DJ short blueberry. 9/29 Trich's are changing fast. Haven't been watering lately do to all the rain. Plants are real real close. Up all night watching. Dog flipped out at 4am but no one was there. I want to wait until I have a little more Amber but I'm super excited. I may end up taking some tops. May end up doing a k bicarb spray today. Haven't decided yet. I'll update as I go. I've been making head way trimming the blueberry. 9/30. Things are looking beautiful. The smell at the garden is amazing. Lots of hard work left. Plants do have septoria and slight pm so I may do a bud wash. I cut a branch from each plant. I think I'm at the point of diminishing returns. Every wet night mold and critters take more and the chances of some idiot coming to try and take my shit increases. I may end up harvesting a little earlier. I'd lie to wait but the trichs look pretty good to me. Still doing all the maintenance required. I am extremely proud of this grow. I fought everything this year. Started with mites and thrips. Powder mildew came with them too. Now I've faced every pest or disease this year. At least it seems that way. I've seen the horror stories on my local Facebook thread. Leave your comments and let me know what you think about trichome stages and whether it would be ok to harvest. 10/1 Rained last night. Defoliated and removed some rot. I'll update later in the day. 10/2 Rained last night and I have A LOT to update which I will later.

End week 15. Flowers don't seem to want to puff out that much which may have something to do with the mites eating my leaves. Neem oil to get painted on individual leaves soon. Don't wanna vape mites.

High on life

week 5 flowering - No herms, strong aroma, and THC production! 🌿🌸🌱🔥 Hello, fellow growers! It's time for another thrilling update on my flourishing journey. We've officially entered week 5 of the flowering phase, and things are looking absolutely fantastic. Here's what's been happening in my grow room: The most exciting news is that I haven't encountered any hermaphroditic plants thus far. It's a relief to see the ladies staying true to their gender and focusing solely on bud development. 🚫⚡️ The aroma emanating from the grow room is simply amazing! The fragrance has become more pronounced and enticing, filling the space with the delightful scent of resinous goodness. It's a testament to the terpene profiles of these strains. 🌿👃🌸 Additionally, the THC production is in full swing! The buds are swelling and becoming denser by the day. It's truly a sight to behold, and I can't wait to see how they'll develop further as we progress through the flowering stage. 🌿🌱🌸💪 While the plants are thriving, I've noticed a slight nutrient burn on the tips of some leaves. To address this, I've decided to dial back the nutrient concentration a bit for this week. It's important to maintain a careful balance and avoid overfeeding, especially during this critical phase. 💧💚 As for the nutrient solution, the pH has remained stable at 6.33, ensuring optimal nutrient uptake by the plants. The TDS (Total Dissolved Solids) level has been consistently maintained between 1150 and 1250, providing the plants with the necessary nutrient balance. ⚖️📈 With everything going so well, I'm filled with excitement for the upcoming week of flowering. Let's continue to nurture these beautiful plants and enjoy the bountiful rewards they will bring. Happy growing, lads! 🌿💚🌸😎

Plants with more direct UV showed much more purple across all 3 plants. The data shows that the number of terpenes in dried Cannabis flowers increases with a “No Red” light treatment for the final three days of production. Based upon these findings, we feel confident in recommending a spectrum control program that eliminates red light output from fixtures for the final 72 hours of the Cannabis flowering cycle. Terpenes are aromatic compounds that give cannabis some of its most distinct aromas from citrus and berry, to more earthy tones. Many species of plants produce and emit terpenes in a diurnal, or daily cycle that is regulated by a complex web of signaling. There are also many plants that emit terpenes at night to attract nocturnal pollinators (Marinho et al., 2014346). Regardless of when the terpenes are produced or emitted, these processes are often dependent upon cues derived from natural light/dark cycles via a native circadian clock (Dudareva et al., 2004). Several light-sensitive pigments are involved in these processes of production and emission, and the different photoreceptors are dependent upon different wavelengths of light to be activated or deactivated. Emission of terpenes is a process that is entirely dependent upon phytochromes and red/far-red light cues in most plant species (Flores and Doskey, 2015). For example, repeated light/dark phytochrome signaling is necessary for the emission of terpenes in tobacco plants (Roeder et al., 2007). Based on previous findings, we hypothesized that a lack of red light and phytochrome-mediated light/dark signaling on the part of the plant is responsible for an increase in terpene content in cannabis. The plant continues to synthesize terpenes, but a lack of red light to trigger the Pr-Pfr shift results in a lack of terpene emission by the plant, thus causing the terpenes to accumulate in the maturing flowers.

Plant Mol Biol 65: 107-12 Abstract Sound waves technology has been applied to different plants. It has been found that sound waves were at different frequencies, sound pressure levels (SPLs), exposure periods, and distances from the source of sound influence plant growth. Experiments have been conducted in the open field and under greenhouse growing conditions with different levels of audible sound frequencies and sound pressure levels. Sound waves at 1 kHz and 100 dB for 1 h within a distance of 0.20 m could significantly promote the division and cell wall fluidity of callus cells and also significantly enhance the activity of protective enzymes and endogenous hormones. Sound waves stimulation could increase the plant plasma-membrane H+-ATPase activity, the contents of soluble sugar, soluble protein, and amylase activity of callus. Moreover, sound waves could increase the content of RNA and the level of transcription. Stress-induced genes could switch on under sound stimulation. Sound waves at 0.1–1 kHz and SPL of (70±5) dB for 3 h from plant acoustic frequency technology (PAFT) generator within a distance ranged from 30 to 60 m every other day significantly increased the yield of sweet pepper, cucumber and tomato by 30.05, 37.1 and 13.2%, respectively. Furthermore, the yield of lettuce, spinach, cotton, rice, and wheat were increased by 19.6, 22.7, 11.4, 5.7, and 17.0%, respectively. Sound waves may also strengthen plant immune systems. It has been proved that spider mite, aphids, gray mold, late blight and virus disease of tomatoes in the greenhouses decreased by 6.0, 8.0, 9.0, 11.0, and 8.0%, respectively, and the sheath blight of rice was reduced by 50%. This paper provides an overview of literature for the effects of sound waves on various growth parameters of plant at different growth stages. https://doi.org/10.1016/S2095-3119(13)60492-X
