Remember that, however you are played, or by whom, your soul is in your keeping alone. Even though those who presume to play you be kings or men of power, when you stand before God, you cannot say, 'But I was told by others to do thus,' or that virtue was not convenient at the time. This will not suffice. Remember that. Day:18 84°F and 65% RH (VPD) for the vegetative stage. Approximately 1.15kPa(assuming leaf temperature is about 2°F cooler than the air), which falls right into the ideal vegetative sweet spot (0.8kPa to 1.2kPa). At 1.15kPa, plants can draw water and nutrients efficiently without risking stress or wilting. It keeps the leaf pores (stomata) open, allowing for ideal carbon dioxide intake and maximizing vegetative growth. VPD is determined by the leaf's temperature, not just the ambient air. Because leaves usually run 1° to 3°F cooler than room air under bright grow lights, my actual VPD will be slightly lower, closer to the 1.0kPa mark. As she transitions from vegetative growth to flowering, one can gradually lower the humidity (to around 45–60%) and drop temperatures slightly to prevent disease from settling inside dense buds when they appear. Night:6 At 70°F and 60% relative humidity, Vapor Pressure Deficit (VPD) is 0.86 kPa. This is right on the cusp of whats optimal for the vegetative stage. During the nighttime, plants generally close their stomata and undergo cellular respiration rather than photosynthesis. Transpiration slows to a near stop, making VPD less critical at night than during the day. However, maintaining a nighttime VPD between 0.8 and 1.0 kPa is highly beneficial in that it ensures the air is dry enough to prevent powdery mildew or bud rot, but moist enough to keep the plant from undergoing unnecessary stress. This range keeps the environment comfortable for cellular processes and prevents large atmospheric swings. Keeping it all flowing. (Not pushing them yet, these are photoperiods) The optimal soil (root zone) temperature for cellular root respiration and nutrient uptake in cannabis is between 68F & 72F This narrow range balances biological energy production (cellular respiration) with the dissolved oxygen levels in the soil, maximizing plant growth and health. Warmer soils hold significantly less dissolved oxygen. When soil temperature exceeds 74F oxygen depletion occurs, inhibiting cellular respiration almost entirely, At 68-72F root cells generate optimal adenosine triphosphate (ATP) via respiration to power root-tip elongation and the active transport of water and nutrients. Too Hot (Above 78F) Root respiration increases, demanding more oxygen, while the water's oxygen-carrying capacity drops. This creates a prime environment for anaerobic pathogens and Pythium (root rot). Too Cold (Below 60F) Root metabolism and cellular respiration slow to a crawl. This severely impairs nutrient and water absorption, leading to yellowing, wilting, and phosphorus deficiencies. A lot depends on whether it's automatic or photoperiod; with photoperiod, there is not as much of a need to push "hard" as the real countdown only begins once the flower is initiated. Automatics, on the other hand, the chronological "clock" begins ticking the moment the seed germinates. It is of critical importance that the seedling growth gets off to the races, understanding that early growth is like compound interest, which will pay off come harvest. This reality is why getting autoflowers "off to the races" early on yields such exponential benefits. The "compound interest" is directly related to the surface area of the leaves. Larger, faster-growing seedlings process more light and build bigger root networks early on, which translates into an explosion of vertical and lateral growth during their short vegetative window. The margins for error are so thin with autoflowers; this early-stage momentum depends on several critical practices. Seedlings exposed to increased atmospheric CO2 levels early in life will develop at an increased rate. To effectively "extend" or optimize the capacity of Photosystem II (PSII) for increased photosynthetic efficiency. In standard oxygenic photosynthesis, Photosystem II (PSII) is naturally limited to the red-light spectrum, peaking at 680nm. Extending its light-harvesting capacity past 700nm into the far-red region requires bypassing the natural limits of standard chlorophyll a. Adding 730 nm (far-red) LEDs alongside standard red/blue lights has been shown to increase canopy photosynthesis by 20–30% in several crops by acting synergistically with shorter wavelengths. However, the limitation is that excessive, pure IR/Far-red light (without accompanying red light) can trigger the "shade avoidance response," causing plants to grow tall, weak, and spindly rather than robust. Utilizing infrared light (specifically the 700-750 nm far-red range) is a viable method to boost photosynthetic efficiency. It acts as a bridge to allow PSII to utilize a broader spectrum of light, breaking the traditional 700 nm barrier. UVR8-mediated signaling (often in conjunction with CRY proteins) triggers protective mechanisms that maintain the stability of the photosynthetic apparatus (including LHCII and reaction center proteins), thus ensuring that the efficiency of Photosystem II remains higher in UV-B-exposed plants compared to plants lacking this receptor. ΦPSII indictates the rate of electron transfer from water to plastoquinone, which drives the production of ATP and NADPH. There is a close link between ΦPSII and the true rate of CO2 fixation (Φ*co2). ETR stands for Electron Transport Rate. It measures the speed at which electrons are moved through the thylakoid membranes in a plant's chloroplasts during the light-dependent reactions of photosynthesis. Infrared light (particularly Near-Infrared or NIR) improves cellular energy by interacting directly with the electron transport chain (ETC) in mitochondria. This process boosts adenosine triphosphate production, which acts as a metabolic coefficient multiplier by accelerating enzyme activity dramatically. Extend then multiply. Far-Red photons interact with plant photoreceptors to accelerate the plant’s biological "clock" or trigger a shade-avoidance response. Autoflowers don't use the plant's biological clock, although the IR will initiate a shade avoidance and make them stretchy. You can just add equal measures of 660nm-680nm to negate the shade avoidance effect. Replacing nights' "darkness" with a combination of IR+ and 660nm. Because autoflowers don't require a dark period to flower, many growers just blast them with light. 18/6 24/0. However, this ignores the plant's metabolic rhythms, where daytime photosynthesis (light reactions) must be perfectly balanced with nighttime carbon fixation and assimilation (Calvin cycle) to avoid bottlenecking plant development. Cellular respiration is a 24/7 process, but it can only function while the plant has the free oxidative capacity to do so. A 100% photosynthetically active leaf cannot perform cellular respiration. The viral trend of defoliation of every leaf that isn't "getting enough light" is of great detriment overall, putting 100% of the cellular respiratory "workload" and responsibility on the 0/4/6 hours of darkness in sub-optimal conditions for enzymatic activity. Photosynthesis captures nearly 100% of the initial energy as carbon, while cellular respiration is the process that unlocks 90% of that captured energy into usable ATP so the plant can use it. Respiration is considered only roughly 30% to 40% efficient. It captures enough of the potential energy in glucose to synthesize around 30 to 38 ATP molecules per glucose molecule. The remaining 60% to 70% of the energy in the sugar is not captured in ATP; instead, it naturally escapes into the environment as heat, which helps regulate plant temperature. In plants, the primary enzymes of the Electron Transport Chain (ETC) and the ATP synthase complexes are typically adapted to function optimally in warmer temperatures (roughly 77°F to 95°F, depending on the specific plant strain). As temperatures rise within this physiological range, molecular collisions increase, speeding up respiration and ATP production. The cannabis plant has a branched respiratory pathway. During heat or cold stress, plants activate Alternative Oxidase (AOX). AOX burns sugars to dissipate energy as heat rather than coupling it to ATP production. This pathway actually functions optimally at elevated temperatures to help protect the cell from the damaging build-up of Reactive Oxygen Species (ROS) during heat stress. Enzyme activity generally scales with heat; there is a strict biological limit. If canopy temperatures in a grow room exceed 104°F, the enzymes and their supporting lipid membranes lose stability. Not saying you need to go crazy, just optimize nights the same as we optimize days. Phosphorus is the driving force behind early seedling development. It acts as the "energy hub" of the plant, directly driving cell division, robust root growth, and the creation of DNA. Without an adequate, easily accessible supply early on, the plant's overall growth potential and final yield can suffer permanently.

Leaf tucking wasn't doing much, far too bushy so I started just to let it go. Cut some lowers after the pic was taken.

Grow diary / germination / The new adventure begins Hello, dear grower friends! 😊 I’m back with a new grow diary and a new adventure. This is my second grow and I’m excited to try new things and improve my skills. I’m thankful for all the support and feedback I’ve received from you . 🙏 In this week’s update, I want to talk about: My setup My seeds My germination My expectations My setup My setup is still an 80 by 80 by 180 cm tent, which is a bit small but nothing else fits in my room. I’m very satisfied with it for the beginning, but I will get a Homebox for the third run because I find the zippers better processed and the inlay reflects more light. My lamp is a LUmatek 200 watt pro edition, which I’m absolutely happy with. It has great handling and processing and it gives enough light for my plants. If I get a smaller tent for a mother plant, I will order from Lumatek again 110 percent. My exhaust is twice as strong as I need it so I can keep it at a quiet 50 percent. It keeps the air fresh and the temperature stable. The temperature is around 25°C and the humidity is around 60%. I water my plants manually according to the Biobizz fertilizer scheme. I use organic nutrients and adjust the pH of the water. The plants are in Lightmix now and will move to 20 l fabric pots in Allmix when transplanting. My seeds As seeds I have this time: 1 Orange Sherbert from Barneys Farm 1 Bruce Banner 1 Apple Fritter 2 Lemon Gelato from a collaboration of Zamnesia and Kannabia These are all very special strains that I’m curious to try. The Lemon Gelato seeds were limited to 500 and I hope they will be fantastic. Of course I have conserved some for later grows. My germination I germinated the seeds in a glass of water for 24 hours and then planted them in small pots with Lightmix. They sprouted after 2-3 days and are now showing their first true leaves. They look healthy and happy, except for one Lemon Gelato seed that didn’t make it, which was probably my fault. The other one is very lively. I have them under the lamp at 18/6 light cycle and at about 50 cm distance. I water them every two days with a spray bottle and a little bit of root juice. My expectations I’m looking forward to the new challenge, especially because it’s a mix of 4 strains this time and I hope we can build on past successes. I want to improve my scrog technique and top the plants at least 3 times. I also want to try mainlining on one of them. I thank you all for stopping by, as soon as it’s worth it there will be a timelapse. 🎥 That’s it for this week. Thanks for reading and stay tuned for more updates on my grow diary. Feel free to leave a comment or a question below. Happy growing! 🌱

27 Dec - 2 Jan 27 Dec Started flushing due to nutrient burn at 26 Dec 22:00 - Finished Flushing on 28 Dec 06:00 2ml/l Flawless Finish 1ml/l Sensizym 400PPM 28 Dec Lowered feed due to nutrient burn. Aiming at 900ppm 29 Dec I don't see any new damage, but I'm keeping an eye on them. 31 Dec I saw a few leaves with probable calcium def, so I added 0.8ml/l of Sensi bloom part A 0.8ml/l of Sensi bloom Part B

Boy oh boy look at these babies grow I'm studying them more and more to ensure they are happy. I've notice that gelato 41 is producing bud spots like thats what it was ment for. Tropi cherry is coming along but not as fast as G41, and runtz muffin im a little disappointed in but i believe that is my fault for im still new and have only grown 1 plant prior to these 3. It also doesnt help i had to cut the vegitation cycle by 2 weeks as well. and further more I was at least able to give 2 clones away, the rest were still good but couldn't find them homes so i had to throw them away. Next time I'll have all the room they need and can't wait to make mother plants of my favorites.

This week the weather has been nice and consistent. Today has been the hottest on record in the UK reaching 37 degrees. This girl has loved it. She has bounced back nicely from her topping making the way for more bud production. fingers crossed this weather continues. 🤞

End of week 2 flower. I moved her into the larger grow space & she is HAPPY!!! Stacking up nicely and taking over the new space. She smells wonderful.

Well am trying to veg as long as possible it it’s nearley time to flip to flower 🌺 dunno if am Goni manage tae get another run 🏃‍♀️ on the go am trying ma best to sort something ye can’t trust anyone these days but fuk it it’s middle of October so a will flip in next week or two then a can relax n let them do there thing looking forward to the stretch faze that’s ma s favourite 🤩 bit lol it yeah a really cannot Sao it goes this but I harvested to early a never dried properly n a rushed and made silly mistakes that impacted massively as much a was happy a shoukd hav waited longer anyway guys wish me luck also told ye feds on case chedderbob112 dizne tell lies real deal @chedderbob112

Start of week 10 and today I have noticed that she is looking a bit droopy so not sure what's happening ? I water her every other day woth roughly 1 to 1.5 litres and always check to make sure its dry before I go for the next round of watering, she has been lovely and healthy up to this point and 100% sure this is a photo not a auto so maybe thst might be the issue and she is crying out to be flipped on lights ?? Any suggestions welcome 😊

Hello folks Havest Day 64 of flowering ( Life cycle 99 days ) Drying with 62% RH--18/21°C since 10 Days Now everything is in jar and in a week or more, I would add my little boveda 62% for a good storage Overall everything went well ! I fell in love with this strain and she will come back quickly in my growroom 😍 The Remo Chemo 1 give me 96g of dry buds The Remo Chemo 2 give me 89g a very good weight knowing that they are described as a small producer Thanks to all who comment / like either to encourage or give advice GD community are The Best 🙏😻 see you soon guys 😘 Peace Love and Weed0

Starting to get pom poms nice and early and throwing out tons of frost..had to raise light and dim to 75% was hitting 1300ppfd without co2. No good. Adjusted to aprox. 900-950 ppfd. Stretch is over woo-hooooo🙌

on week 6-7 nute recipe since w5, 950w main and undercanopy lights + 192w of lil sidelights. smelling nice now

Athena for the win I know the Ogs goin on Plan with a defo on Day 21 from Switch but we reachin new ways and i switched from the normal schedule defo on Day 21 So what i did is short that period and instead of a Heavy defo and 🍭 on Day 21 i did the 🍭 on Day 14 and a slightly but good defo and on day 21 another not so Heavy defo so the shock for the Girls is not so Heavy like you make a Big defo and 🍭 on day 21!

Started flush today been a good few days for putting on weight

One week of 12/12 and there stretching out nice I've defoliated the central cola to allow the side branches to catch up. Will start to feed soon

Llevo poco tiempo pero la verdas que bastante bien, cada vez vamos aprendiendo mas

Die 5 Frosted Guavas stehen stabil in 18L Gold Label. Eine ist etwas kleiner, deshalb wird erst nach Ankunft der Mars Hydro E3000 getoppt, damit sie vorher aufholen kann. Zusätzlich stehen 2 White Raspberry Truffle als Backup im Zelt. Beleuchtung läuft mit ~195 W (2× Honguan auf 50 %, Hortione auf ~70%). Der Wuchs ist kompakt und gesund. Sobald die neue Lampe hängt, werden alle gleichzeitig getoppt für einen gleichmäßigen Canopy. Mehr Updates folgen ✌️🌱

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 🚀

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.

Las plantas van creciendo estupendamente, de momento no les he dado ningún tipo de fertilizante. He aplicado LST.
