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.

Week 1 Day 1 - 8/12/2023 1st Water change Day! Such a special time it is when you remove the little bit of Nutes that you gave them as an appetizer and you give them their first real meal. Added 39 Gallons of Water to my system SILICA= .5mil/Gal = 19.5 = 20mil Root Drip = 1mil/Gal = 39mil Cal Mag= .25mil/Gal = 9.75 = 10mil FLoraMicro= 3.0mil/Gal = 114mil FloraGro = 2.0mil/Gal = 78mil FloraBloom = 2.0mil/Gal =78mil ORCA= .5mil/Gal = 19.5 = 20mil Week 1 Day 2 - 8/13/2023 Everything is looking good the roots are making thier way to the water and the new grow is looking nice and green. Week 1 Day 3- 8/14/2023 Everything is right on track, they are looking beautiful and in the praying postition all leaves happily lifting towards the light. Week 1 Day 4- 8/15/2023 Looking beautiful today and looked like she could use her first haircut.. gave her a TOP off. Roots are laying in the water everything is looking right on track.. Week 1 Day 5- 8/16/2023 walked in and the humidity was under 60.... ohh noooooo.. So I added 2 humidifiers to the tent and attached them to my InkBird controller which is set to 62. She had roots nicely in the water.. this grow is on!!! Week 1 Day 6- 8/17/2023 Humidity was a little low this morning, so I refilled the humidifiers. Other than that, the temp looks great, the PH looks great, the PPM looks good the plant is in the praying position and all damage from the little drowning seems to have been fixed. Happy Happy. Week 1 Day 7- 8/18/2023 Yay.. week 1 in the books, roots in the water growth has started first hair cut given and both side nodes are growing. Everything is looking good and on track.. A lot better than week one of the last grow when I had them drowning week 1. Really excited on how this grow is going to come out.

Light defoliation on both of them, They are both in full flower now, the autopot seems to go a bit quicker

08/11: La troisième semaine de floraison commence enfin on devrait les fleurs prendre forme. J'espère que le stretch est fini car elle est assez grande et doit laisser un peu de place au autres. 08/12: la troisième semaine débute sur une note un peu amer. Certaines feuilles se détériore à une vitesse folle, ainsi que des tâches brune. Premier réflexe GHE essential et cal-mag agent de Canna ce matin. Espérons que les prochains jours seront plus cool et que cela vas arranger mon problème. 08/13: après avoir fait plus de recherche je suis enfin tombé sur un article sur le blog de pevgrow et mon problème correspond en tout point à une carence en magnésium. Je devrais voir voir des améliorations dans les 4 à 7 jours. Et bien-sûr continuer à donner du calmag. Le problème viendrai du fait que je tourne en 24/7 avec les auto's enfin c'est ce que je pense après avoir croisé les conseils et avis des "growers" de GD et certains articles. 08/14: c'est dernier jours ont été intense pour moi, lors de mon premier diaries j'avais déjà eu le même problèmes avec une purplequeen auto à l'époque je n'avais pas de calmag... enfin tous ça pour dire merci à la communauté growdiaries.com qui m'a conseillé et supporter. Maintenant cela c'est stabilisé et n'atteint aucune autre feuilles, les nouvelles feuilles sont belles et viguoireuses. Me voilà rassurer et surtout j'ai encore appris de nouvelles chose sur la cannabiculture 😎😨🤓 08/15: elle a créée une belle masse de feuilles entre temps, je vais appliquer une grosse defoliation après le prochain engraissâge histoire d'être que les carences ne sont plus d'actualités. À part cela je me contente de couper deux feuilles par jours. #46 08/16: tout est rentré dans l'ordre ouF :D - la production de trichromes à bien commencé, une légère odeur typique à la weed qu'elle que soit la variété en début de flo. se dégage de la growbox. je suis enchanté! Maintenant j'epère que le switch d'engrais càd changer "BioBizz bloom/topmax" pour "Canna PK13-14/Boost Accelerator" vas lui plaire à la jolie dame #47 08/17: apres une de nuit de réflexion: arrosage/engraisser (canna calmag (.6ml/L)/BB blom-topMax (1.2ml/L chaqu'un)/ AN BigBud-BudCandy (1ml/L chaqu'un) ce matin. J'essayerai canna pk 13 14 et boost accelerator sur mon prochain plant. #48

Dear diary, Week 2 done and on the books! Everything went mostly fine up until the very end of the week were I noticed some strangeness with another one of the strains in the tent. More info on that will be in my other diary for Gorilla Cookies and will be covered more overall in next weeks update as I try to fix any potential issues. 🍀🍀🍀🍀🍀🍀🍀🍀🍀🍀 ⏰ Day 11: Calmag foliar applied 2 times during the day at 0.8ms and corrected ph to 6.3. They also got their regular feeding at 1.27ms 6.4ph with me increasing the light to 250ppfd. ⏰ Day 12: They were given a foliar and watering of calmag water at 1.13ms and 6.3ph early in the morning as issues had not cleared up. Later in the evening they got a regular feeding at 1.41ms, 5.9ph and lights were increased to 275ppfd. ⏰ Day 13: 2 calmag foliars, gave feeding at 1.54ms 5.8ph and increased lights to 285ppfd ⏰ Day 14: They have reached 3 nodes marking the end of seedling stage and beginning of veg! They were fed with 1.53ms 5.8ph and four 3 liter airpots was prepped with 75/25 coco/perlite and watered with the same feed until runoff before transplanting. As I can only grow four plants W.C #1 and #3 were selected as the final two. Temps are around 26 and RH 75% with lights on and 24C 80% off. Will be taking down the RH slightly over the coming few days to 65%. ⏰ Day 15: Gave the girls a feeding at 1.57ms 5.6ph. Also increased light to 305ppfd and they do look a bit droopy, but that’s not to surprising after the transplant. ⏰ Day 16: Daily feeding at 6ph 1.59ms and increased light to 320 ppfd. Aiming for 465 ppfd by the end of next week as that would move us up from 20 to 30 DLI. ⏰ Day 17: Sprayed a foliar coat of Leaf Coat from Biobizz as prevention for pest in the morning. For the evening they got their feeding at 1.58ms 6.2ph and foliar spray of calmag as a plant of the other strain in the tent is looking a bit odd.

the canopy is balanced (see vid), a rather intense green colour, no sign of deficiency (I moved my lamps up 10cm to prevent the tips from bleaching further), the stems look strong, and no more flies or spiders in my tent :) onwards to the flowering stage! 12h/12, still under my MarsHydro, 2 lamps, 210w. can't wait to see the pistils emerge!

Light defoliation this week very couple of day's. Humidity up too at weeks end due to rain not to worried . Get it 1 maybe 2 weeks and if not down below 60 will have to set up dehumidifier.

Tap root issues - too long in jiffy block Still working on dialling in VPD

Cherry cola in the back right is catching up from starting off a mutant! The 2 lsd-25s up front are growing fast and great no problems at all with them. The back left is the big bud tied town with major lst and is also showing no problems. All 3 are going into flower the cherry cola I would say is about 2 weeks behind even though it was started the same time. (36days ago) cronk nutrients seems to be working well with the Bonnie and Clyde auto line! And got a greenhand genetics started in a 5 gallon pot in the middle

White Truffle is a very promising new strain from Zamnesia, let's see how it goes. ** Remember that we are growing a plant worked with the techniques indicated and another left to grow without pruning to preserve its speed; in the previous/next diary you will find the other plant of the same variety. In this diary we find the plant worked with the Main Lining and here we immediately noticed that it is a plant with irregular internodes, that is, the mini branches are not parallel on the main branch and are in spurious numbers and strangely positioned, a big gamble to decide what to keep and what to leave. I hope I have not cleaned too much, because I have done it but it seems wise to me to try to leave everything that can see the light better. We are in a 100% organic configuration, the soil is recycled Promix + 1/3 fresh soil + 10% Perlite + RQS Mycorrhizae Mix (4 g in the mix, 1 g under the small fiber pot). We have switched to the early flowering program We feed with // 1 ml/l Power Roots - 1 ml/l Pure Zym - 1 ml/l Sugar Royal - 3 ml/l Alga Bloom - 1 ml/l Power Buds We spray 5 ml/l Vita Race Foliare once a week.

Welcome to the pink feno hunt. I have a good feeling about this pack of 3 from fast buds. Very exciting. This is an attempt to recreate that one strawberry smoke... We will be growing these in bottles first so i can have a humidity cap on them (my tent is busy). After about 2 weeks we will have more room. The bottles have air circulation holes and a drain on the bottom. Plan is to top these in their temporary homes and then transplant them in larger 20 L pots so they can be trained. No nutrients for the first week. I will just be spraying their pots with PH water when they need it for humidity. Look for weekly updates.

8/28: She's my last CC bean out of the original 7 that I received. (only ordered 5). I will not be ordering any more of them, but it is really good bud, so I figured why not.. I had 2 out of 3 seeds germinate last grow, and only 1 out of 4 this time....if they hadn't sent me the two freebies I might not have even been successful at all last time... I will FIM this one to try and increase the yield a little... She's in the 5gal tall black plastic pot with the white zip-tie loops on both sides.

Blue Mystic buds are starting to develop. Left lemonade nearing completion, right lemonade is several weeks behind left lemonade on bud development. Left lemonade has purple hues in the buds.

Olá growmies! Esta semana parei com o LST na esperança que ela ganhe mais altura nestas semanas. Até agora não tenho tido grandes problemas. Entre as regas tenho dado 0.5L de água com pH regulado quando as folhas começam a esmorecer. 20Nov - Alimentada com 2,25L de água. Runoff EC: 1.50 / runoff pH: 6.5 Se tiverem alguma dica para me dar, estejam à vontade!
