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.

3 autoflowers which is Outlaw Amnesia, Purple Punch, and Strawberry cough are well undergoing veg stage. Since these 3 plant genetics breeded are a mix of 2-3 different strains. The grow results from this seed breeders are amazing no complaints. I am really looking forward growing single strain very soon from international seedbanks asap once i finish experimenting all of my custom breeder strains. I am having a crazy overthinking with 2 of my AK47 since they are seeds generated from a hermie AK47 autoflower. The issue is more of a thought process whether the plant will flower since these 2 of them are under 1 tent with 3 Autoflowers😂, i hope they will follow the autoflower traits and not photoperiod. If they are not flowering, i was informed to flip the light to 12-12, If this situation happens, the only possible outcome i can think of is to defoliate/shwazz them and then flip them sf2000 to 12-12 right only i harvested 3 of the Autoflowers. Officially planted these babies on Nov 9, i will log into GD diaries every Sunday. Officially added 0.5ml of BigBud per litre, a very minute ammount just to top up some P and K since 3 plants are entering preflowering soon.

We are getting close to the finish 🙃 I’m really happy with how the flower went at the end, as the lady’s are really growing bricks Buds are really hard to the touch, one smells really earthy with a touch of diesel, one smells like bubblegum mixed with lemon and two smell like pure juicy lemon diesel. I really didn’t except this, but the smell is incredible and the bud structure too. I’ll start flushing as soon as most of them are milky, I also thought about giving them 3 days of pure darkness at the end, but not sure yet. Thanks for all your advice and feedback so far :)

week intel: we getting close to end of ripening , this week i raised drought , Nitrogen and E.C stress by feeding them 2 times per week and raised e.c to 3 to cause real stress that will help increase terpenes production stresses : Nitrogen deficiency Stress by removing the fertilizers that has N in them Drought stress via removing one meal in week high E.C stress around 1.7 and the other feeding day 3.0 , 2 times a week feeding: no more Nitrogen i feed them 2 times this week with this order : day 1 : i feed them high with Bio-Bizz Top-Max + Feeding Booster about 850 ppm - 1.7 e.c to cause a medium e.c stress. day 3 : no more feeding this day day 5 : i feed them very high dose of Bio-Bizz Top-Max + Feeding Booster around 1500 ppm - 3 e.c to cause high e.c stress guide of the week : be patient in the last weeks, never hurry for harvest because its the time of ripening in last 2 weeks you should let plants to do their work last weeks of ripening is the time to break the limits we should cause 3 stresses as i said above Nitrogen stress , Drought Stress , E.C Stress

So these were meant to be 70 day seeds! And we are on day 75!! They might of been if I did it in a tent with lights and fuck ton of nuts. As I have been doing it in a pop up green house in my garden and using organic nuts (watered-down coffee grounds at veg stage) and then (2-3 banana peels left in water in water for 2 days when flowing) I think they have turn out OK. Still got about 2-3 weeks left I think till harvest. Smell so strong but ever so sweet. Again can not thank you enough everyone that has helped with tips.

Keep watering with same nutrients mix, because I had add before to soil some extra worm castings, palm tree ash, bat guano and egg shells. Day 24. keep doing all the same feeding with 2.5L nutrients mix.

Es ist soweit! Am Freitag habe ich die fünf Easy Buds nach knapp 11 1/2 Wochen abgeschnitten und geerntet. Leider musste ich feststellen, dass eine Pflanze ziemlich stark befallen war. Ich vermute eine Milbenart oder möglicherweise Fliegeneier. Unterhalb der Blätter waren etliche dunkelgelbe und dunkelbraune Eier, die man auf den ersten Blick kaum erkennen konnte. Bei genauerem Hinsehen sieht man jedoch, dass sich der Befall auf die ganze Pflanze ausgeweitet hatte. Glücklicherweise blieben die vier anderen Pflanzen verschont. Aus diesem Grund trockne ich die Pflanzen auch getrennt voneinander. Die befallene Pflanze wollte ich nicht direkt wegwerfen, sondern erstmal trocknen lassen. Im Nachhinein werde ich schauen, wie ich mögliche Schadensbegrenzung betreiben kann. Die vier gesunden Pflanzen werden in einem geschlossenen Zelt in einem Trocknungsbeutel getrocknet. Die befallene Pflanze habe ich in dem Folienzelt aufgehängt und mit einer Plane abgedeckt. Nach wenigen Tagen der Trocknung sieht soweit eigentlich alles gut aus. Die Eier scheinen nicht mehr zu schlüpfen, sondern fallen von der Blüte ab oder verschrumpeln zu Kompost. Ich hoffe, dass es dabei bleibt. Der Geruch hat sich nach dem Abschneiden deutlich verändert. Schon nach der kurzen Trocknungszeit kann ich einen intensiveren Geruch feststellen, der sich noch nicht so richtig beschreiben lässt. Die Blüten waren stark mit den sogenannten "Sugar Leaves" verwachsen, weshalb ich sie grob getrimmt habe, um sie zum Trocknen aufzuhängen. Nachdem die Blüten vollständig getrocknet sind, werde ich die Buds noch einmal einzeln trimmen und durch meine Trimm-Maschine von Vevor jagen. Der Ernteprozess hat zu zweit circa eine Stunde gedauert. Die Pflanzen waren zum Zeitpunkt der Ernte noch sehr gesund und kräftig. Die Verwurzelung war trotz des geschlossenen Topfes sehr gut. Die schönste Bud hat definitiv die zentrale Pflanze, Greta, ergeben. Nass hätte ich den Bud auf mindestens 12 g geschätzt. Ein Gesamtgewicht des nassen Pflanzenmaterials habe ich nicht ermittelt. Sobald alles trocken und fertig beschnitten ist, werde ich das Tagebuch um den trockenen Betrag ergänzen. Stand jetzt würde ich schätzen, dass der Ertrag aller Pflanzen bei circa 40-50 g liegt, was mich für meinen ersten Grow ziemlich zufrieden stellt, besonders in Anbetracht dieser wirklich sehr simplen Strain. Mehr Infos und Fotos folgen in Kürze, wenn das Curing beginnt. Bis bald! :)

(Have been thinking about it, decided to just do both runts under one diary and just using the Green Sensation on them both. Had only used growdots on the other one, but will be bringing the other runtz into this diary aswell) Beginning to add the Green Sensation nutrients this week. Really curious to see how she looks in the next 2 weeks now that its being added!. But these Runtz are growing well, looks great to me so far nothing crazy , bit different pheno then my other grow but I'm happy with both .. Can't wait to see how they flower fully. Not much else was done, I do regret not training but wanted to let it do its thing , didn't have the space for anything big (I never go for massive, one of these days I'll veg longer tho just for the experience of it) Had cut off a handful of leaves that were laying on each other. Did alil form of lollipoping but not extreme. And only plan besides Green Bay is the Recharge will also be used 1x weekly. Lights are currently around 32 DLI roughly 700/750ppfd off the top of my head. I'm thinking around 40 I may push to peak but we will see, no added CO2 besides environmental atleast its above 500 pretty steady raises to 8/900 amd alil higher when I'm in talkin shit to them. The water input is picking up in frequency aswell. Watering every other day still due to how cold it is they are drinking slow but their just about 3/4s of a gallon currently.. Temps have been way lower this run then I really wanted just last heater I had decides to quit on me.. big area so tough to replace that thing and of course it was just out of warranty lol by 2 months. The one is getting some purples on it this one's pretty light green , ec is in range after a quick lil media test, had been curious if she was hungry so decide to check did alil runoff when watered prior to feeding the plagron. Ec was fine and PH was alil low so bringing that up as I feed. Besides that tho , their smelling really sweet.. literally like a pack of runtz already ...anxious to get to smoke some of my first try at a runtz plant! As always I appreciate everyone's time checking these things out.. thanks for your support and encouragement. And another big thank you to Zamnesia and Plagron for throwing this together!! Been a fun contest so far.. Beans: https://www.zamnesia.com/uk/ https://www.zamnesia.com/us/
