Getting nice and tall this week

Gorilla cookies and cherry cola are both hitting flower hard! The smells are pungent,the buds are sticky and the stems are strong! We’re getting nice fat buds on cherry already and gorilla isn’t too far behind her. They’ve taken very well to the feedings they’ve been given and all training done to them. So far I’m loving both of these strains 🔥🔥

Views expressed are my own. All opinions are my own. The opinions expressed here belong solely to me and do not reflect the views of Growdiaries or Grandcru Genetics. The cannabis strain Grape Guava can be a purple strain, depending on its specific phenotype and genetic makeup. While not all phenotypes of Grape Guava are purple, some variations, such as the Zatix Grape Guava, are noted for their striking purple appearance due to the genetic expression of anthocyanin pigments. Grand Cru Genetics is a cannabis seed bank that emerged in 2018 from a group of breeders in Madrid to provide a satisfactory experience to all cannabis users. "If we do things, we do them well. Due to our experience in the sector and our taste for excellence, we know high quality and we seek it in everything we propose and do." "We have a “cultivate without giving up” philosophy that we apply to everything we do. We do not give up, we are friends of change, and we adapt as necessary in a still restricted sector." "We speak relaxed because we know how to relax. We are not intense or preachy; we accept everyone as they are, and we understand that farming is not for everyone. But for those who do, we are here to accompany you. We like to do it and tell it. We are experts in the field because we are the first to do it. We speak from experience and connect with others because we share the passion for cultivation." "Cannabis has the ability to show us a world of possibilities. When you cultivate and live its growth process, you enjoy a path full of emotions and not just the final destination. At Grand Cru we find beauty in small things. We are attentive, observant, detail-oriented and aware of everyday things, and we savor them without rushing." In a garden of green, Grape Guava gleams, With its fruity aroma, enchanting dreams. Clusters of grapes, guava's sweetness ignite, A strain so divine, in purple and white. Euphoria whispers, a lush fruity haze, Grape Guava's embrace, a tranquil daze. Off and away.@1400ppm. The increased CO2 allows plants to thrive at higher temperatures, which in turn necessitates higher humidity to maintain the ideal VPD for healthy growth and transpiration. 80F -5F = 75F LST with 70% RH = 0.72 kPa. Higher temperatures and humidity promote rapid growth, nutrient uptake, and photosynthesis while maintaining a lower stress level. Temperature influences the rate of enzymatic reactions involved in aerobic respiration. Enzymes, such as those involved in glycolysis, the Krebs cycle, and the electron transport chain, work most efficiently at an optimal temperature range. In low temperatures, enzymatic activity will slow down, thus reducing the rate of aerobic respiration. In high temperatures, enzymes can become denatured, thus impairing their function and stopping the process of aerobic respiration. Glucose is the primary fuel for aerobic respiration. The rate of aerobic respiration increases with the availability of glucose, as it is the starting point for glycolysis. If glucose levels are low, cells may rely on alternative energy sources such as fatty acids or amino acids , but these processes may yield less ATP or be less efficient. To determine this effect, carbon dioxide volume was measured (as carbon dioxide is an output of aerobic respiration) 18/6 with the 6 being IR. The near infrared (IR-a) borders around 700nm up to 1400nm @ photon par flux density of 1.8 instead of darkness, keeping temps overnight a neat 77F-80F. I think of my tent as a lung. What goes in must come out. When the rate of air going out exceeds the amount of air coming in, it creates a negative pressure. Tent concaves (bends in). If set up correctly, the RH will begin to drop slowly to the desired level I set, and the extraction turns off when it reaches the desired RH. The plant, as it performs cellular respiration, will always release more water into the air; therefore, the RH% of the tent overnight will increase, as long as oxidative phosphorylation is occurring. As soon as the RH% creeps back up to 55%, the extraction turns back on, over and over. This creates a strong pressure differential, which will work wonders with mass flow. Replicating high and low-pressure fronts in nature. Critical for oxygen diffusion at the critical time of peak cellular respiratory function.. Moisture will not transfer from a saturated atmosphere to another if that air is already at or above its saturation point, meaning the air can't hold any more water vapor. Once I understood that water is produced as a by product during cellular respiration, specifically at the very end of the electron transport chain (ETC) where electrons are finally transferred to molecular oxygen, the higher the RH of the air, the more resistance there is for more moisture to be added to that environment, and effects the ease with which it does so. But none of that water comes from the pot; it's pulled from the air. If you run high daytime RH, your medium/pot is 100% reliant on transpirational root pull to move water. ZERO evaporation happens across the atmosphere if the tent air has high RH%, the medium cannot release its water through evaporation. Once a canopy develops, light no longer slowly wicks and evaporates from the topsoil. The Soil-Plant-Atmosphere Continuum (SPAC) describes the continuous pathway and process of water movement, driven by a gradient in water potential, from the soil, through the plant's roots, stem, and leaves, and finally evaporating into the atmosphere through transpiration. There is evaporation, there is transpiration, and then there is evapotranspiration; Evapotranspiration (ET) is the combined total of two processes: evaporation (water lost directly from soil and surface water into the atmosphere) and transpiration (water released from plants to the atmosphere through their leaves). Evapotranspiration represents the total amount of water that moves from the medium into the air. There is no such thing as a medium with too much water, only a medium that retains too much for too long. The water must always flow efficiently from one atmosphere(Medium) to another(Air) in a timely manner. Moisture is a critical factor for bacterial growth and decay. Dictating how long it's allowed to sit in any one location for any given period is a key preferred control. To ensure a net reduction in a bacterial population, the rate of removal (ET) must exceed the rate of bacterial growth (decay rate), which is often modeled as a growth rate for the specific bacterium under the given conditions. By optimizing daytime VPD, we also optimize conditions for bacterial growth to explode exponentially above 77°F.. If water is allowed to sit in a medium without an escape within a timeframe, nothing good will happen. IF High RH is maintained overnight as well as during the day, placing 100% of water movement at the behest of daytime transpiration, roots can only pull where they can reach, and if soil is compressed above a certain point, moisture will become trapped in a medium with no way of moving day or night. This will begin the countdown for decay to take hold. When water stagnates in a medium, it loses oxygen, creating anaerobic conditions that foster the growth of harmful microorganisms like bacteria and fungi, which can produce toxins and disease vectors. Thigmomorphogenesis, the process by which plants respond to mechanical stimuli like touch by altering their growth and development, results in significant morphological changes to improve survival against mechanical perturbations. This complex response involves sensing touch and initiating physiological and genetic responses, leading to changes in form and structure over days or weeks. The process is triggered by physical forces such as wind, rain, or touch. Plants adapt to these stimuli by changing their shape and structure, which may include slower growth, thickened stems, or altered leaf development. Plants possess sophisticated mechanisms to detect even subtle mechanical stimuli and initiate responses. A variety of molecules, including calcium ions, jasmonates, ethylene, and nitric oxide, are involved in signaling these mechanical inputs. Touch can induce the expression of genes that encode proteins for calcium sensing, cell wall modification, and defense mechanisms. A plant exposed to constant wind may become shorter and sturdier. A plant that is touched frequently might grow more slowly to conserve energy and develop thicker cell walls. These changes increase a plant's resilience and ability to survive in harsh environments. Let's get Thiggy with it.

The girls are exploding with energy 💚 no stress, no drama just pure upward momentum 📈 🌡️ Air Temperature: 22.6 °C 💧 Humidity: 52.2 % 🌬️ VPD: 1.31 kPa We’re sitting right in the sweet spot 🎯 I slightly increased the VPD to lower mold risk and tighten moisture control. They adapted instantly, like they knew the mission 💪 💡 Light running at 85% power no burn, no stretching, just disciplined, powerful growth. 🌿 Sativa pushing almost 60 cm, reaching like it’s chasing the sky. 🌱 Indica holding strong at 40 cm, compact, dense, built like a warrior. And now the poetic truth of it all: They don’t rush. They don’t doubt. They simply respond to balance. Every leaf is a quiet signal. Every new node, a statement of intent. Roots anchoring deep in silence, while the canopy writes its story in light. This isn’t just growth it’s controlled chaos shaped into structure. Energy transformed into form. Patience turning into power. The room feels alive. Stable. Intentional. Like something bigger is slowly unfolding. This cycle… is going to be legendary. 🔥🌿

one of the plants could not stand the heat any longer. I cut almost all of its branches, I will cut it completely. Others struggle with the heat, but there's nothing I can do.

Ya se acerca el día de la cosecha aunque sigue produciendo flores nuevas, el olor es fuerte, penetrante y hasta cierto punto picante. Estoy regando solo con agua y así seguiré hasta que la corte.

Just finishing week 4. Damn fungus gnats got me down. Laying some mosquito dunk water on them and expect / hope to have that eradicated soon. Going to do my second leaf stripping in first day or two and a second top dressing, which I do every two weeks up to week 5 or 6.

Acabo de hacer el lavado de raíces. Ya queda poco, y estoy deseando ver el resultado. No tengo ninguna favorita, porque todas tienen una pinta tremenda!! La Oreoz es preciosa, la vanilla frosting tiene unos cogollos increíbles, la Og kush es mega resinosa ( eso si, una se ha quedado pequeña y con cogollos más flojos), la Blue sunset sherbert huele increíblemente afrutado, y la Rainbow mints es super productora y suculenta. Feliz semana amig@s!

420 Fastbuds Week 9 Cherry Cola Auto What up grow fam. Week 9 for these girls and from the looks they are getting really close to being ready to chop. The smell is absolutely heavenly sweet. When pulling dead leafs off your hands get sticky as can be so keep some alcohol close by. All in all Happy Growing

Week 5 already? Plant is struggling to catch up after such that two week lag period where it didn't do a thing. Still, things are starting to get encouraging so now watering every day at 2 hours after lights on. Added a webcam to the tent to watch what is happening. Noticed that at 12 hours after lights on, the leaves would start to wilt. Flooding at that time didn't have any noticeable effect before lights out, so I added a flood at 9 hours in (half the period). Pushed the wilting back to 14-15 hours after lights on, and just a little now, but still not completely solved. Grew from 2 inches to 7 inches this week!

7/9 final week before harvest starts today Last watering end of this week. They are right on time with exact 9 weeks flowering

All looking frosty around day 42 of flower! Just been on water for the whole of flower! Watered with aact as well every other week but real happy with this run!

Starting the second week of flowering, first day! And they are beautiful.

You should try this one. I will update when she dry.

Blueberry Lime Kush AD Fuck, it's a boy...
