Hi Gromie's, upped nutrients & turned light up to 75% (360w), wich has helped bring up temps to 22-24°c really good growth. DD#2 ,DD#3, DD#4 are 1 week younger than DD#1, had originally fimmed 2, 3,&4 but changed my mind & decided to top them & mainline them. I have topped DD#1 for a 2nd time & I am following nebula haze's (grow weed easy.com) method of mainlining keeping the first & 3rd node's to give me 4 cola's per side, 8 total. So till next time Gromie's, ☮️👍🤘

Starting to see signs of flowering started transitional bloom nutes.

5/14 - Day 54/Day 14 Flower Water uptake is increasing significantly. Been watering about a half gallon to a gallon every 3 days. Stretch has started to begin so I've been starting to get more aggressive with the LST. Darker green color has started to return to the leaves. No signs of deficiencies and my girl looks happy and healthy.

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.

Looking great going into day 8!!! No nutes just plain tap water!

just cut 1 of my 2 hindu kush auto will inform in the next days...

Brought to you by a pair of Mars Hydro SP3000s. Grow on Earth. Grow on Mars. 69 😉 days from seed soak. Veg is done. Sending off to Mars to flower cuz I installed 2 SP3000s in my 2x4 (60x120) tent. Introduced Nectar and have been feeding full strength now. Seems like I have to water every day...1 gallon each of full feed per plant, 18 hours later seems like they are thirsty again..leaves drooping down and perk up after water. I’ll start doing 1.5 gallons and up the nutes....maybe it’s the new lights. Photone says: ~90000 lux in middle, ~70000 on the edges/sides. I think I’m pushing it but it seems my plants are loving it. That’s it for now and thanks for stopping by. Happy growing 🌱🌱🌱

Just coming to the end of week 7 she’s had 8 days of flush an 24 hours of darkness an she’s been chopped just waiting on her to dry an cure abit before I smoke her an let everyone know how she smokes had fun growing this photo period as it’s my first also only 3rd ever plant I’ve grown taking that into account looking at the final result is uplifting to say at the least an has give me the motivation an carry on an push my new found passion further thanks everyone who helped me along answering questions love this friendly bud community!!!💚🍁

The Sweet Cheese have been building up frost already and we are only in the start of bloom. wicked citrus sour candy smell, i cant wait to taste it! Orange Apricot Glue also starting to become frosty, but is taking is time to go to full bloom, gonna be big, when she for real starts blooming. gave both plants a dose of Calmag, due to some rust spots appearingz

Gorilla cookies auto's are doing 3days of darkness b4 harvest now I can focus on the photo periods

Heatwave Tested, Veggie Blessed ☀️🌱 Rolling into Week 3 of veg, and this little mystery girl is looking absolutely beautiful. Compact, vibrant, and showing all the right signs of healthy growth. 💚🌿 This week brought the heat—literally. We hit over 40°C in direct sun, and although she definitely felt it, she powered through like a champ. No major signs of stress, just a little sun-kissed and stronger for it. 💪🔥 I gave her a solid dose of effective microorganisms a couple days before feeding with BioBizz Grow, and she’s been loving it. The green is deep and rich, and her structure is nice and tight. She’s holding up strong, bouncing back from the heat, and I’m super excited to see her take off in the coming week. Something tells me she’s got big plans… 🚀🌼

Started to dial down the nutrients, can already see a slight colour change in the leaves as they start to turn autumn colours with the reduced nitrogen Did a flush/refresh of the roots using florakleen 0.5ml/Litre and left it in the reservoir for 2 days before dumping and adding fresh nutrients. The roots look bright white afterwards where they were nutrient stained a reddish brown before. I swapped the side light from the left side to the right side to promote some more bud development on that side lower down Happy with how the plants are looking but I had hoped that the buds would be a little fatter by this stage. Clear winner so far is the bruce banner which has by far the biggest and most dense buds, then the gorilla glue next, then the blue dream although her buds are tall and skinny, then the gsc comes next with the critical last, most of the buds on the critical are still very small (it's the shortest plant and furthest away from the light)

These girls been growing up Amazingly. They are now in flush mold until harvest

The smell is ABSOLUTELY divine 🤩 The trim was super easy,the buds are super dense & sticky👌

D1: fresh 10L flowering mix Repositioning branches but no more HST

coming along nicely now that it is starting its 2nd week of flower this is actually the first week of flower to me because the first week is a transition period where balanced nutrients are required. This is an 8 week strain. Let's see how long it actually takes to mature.

Start of 3rd week of flowering looking good. Pollinated last week with some feminized Black Jack Auto pollen. Will make for a nice feminized hybrid. Great 3rd week of flowering.

I love growing its a big passion of mine , and the fact that GD exists makes everything so much better, one can interact with others and enjoy and learn from each others. Thank you all growers love and keep them green <3 <3 <3

This girl is about finished here sister came out to about a 1 1/2 ounce hopefully this big girl is more overall good experience I don't have to say I will be doing these again because I already have 2nd and 3rd generation clones who am I tho I. Just a newbie 😌 lol
