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.

CRAZY NIGHT (Continued) And not only is Frontdesk girl steaming mad that NX hit it and quit it (apparently she was looking to make him breakfast and then introduce himn to the family!!!), she brought along her rather large brother! Frontdeskgirl sees the Stephanies, they see her, large brother see NX's eyes and everyone puts 2 and 2 together. Stphanie 1 was the first to smack NX accross the face, followed by S2 with a kick to the shin, more from S1, S2 with the assist, NX starts hobbling away. But no! Now Frontdesk girl has made it to the group and shes swinging at EVERYONE!!!! Luckily myself and the others in our group were safely out of arms reach and were able to witness this spectacle alongside the curious morning Montreal onlookers. The stephas start fighting back with FDG, and the brother starts to chase my brother!!! Now in most situations, my brother would get backup, bit there was just too muych going on to watch, the big dude obviously had a bum knee, and my bro had a head start and an athletic build. So, there we were, bags dumped outside the hotel, a classy fight on the sidewalk in front of us, my brother running away into the sunrise, and a whole day of events planned. I picked up my shit, my bros shit, my buddies did the same, and we noped the fuck out of there., leaving the girls to figure that shit out themselves. Never saw the Stephanies again. To this day they could still be in Montreal, who knows. My bro is still alive, and I will never know what happened to Frontdeskgirl. DIARY STUFF CHOPPED IT!!! Its huge, it stinks, and I cant wait to show you the harvest and cure photos. Im a big fan of this strain, and I hope it makes it to the FB roster!!!! Thank you Heather and the Fastbuds team for allowing me to grow and profile this wonderful genetic

Week 0 (germination week) 4 seeds directly into Strain chosen for Yield, this run will be about increasing yield, LST, & Defoliation techniques. Any advice any of you may potentially have for Training auto-flowers would be greatly appreciated Here is to a great Cycle and bountiful harvest!

400 ml de sólo agua por planta. se quitan las botellas tipo invernadero.

D67 removed ScrOG and repeated LST on left plant so lower buds will get more light. There is not enough space in tent to do the same with the right plant.

Was on a 2 weeks vacation, just got back, found a lot of yellow leaves on the Runtz which is normal at this stage I think, te Sour Diesel is looking light green and the G13 is looking great and smelling marvelous. I will be adding some natural flowering mix

4/1/21 - Both plants were transplanted into 5 gallon fabric pots with Ocean Forest soil by Fox Farm Nutrients. I will be using plain water for the next two weeks to allow the plants to get acclimated. (See video) 4/2/21 - Watered both plants with water (ph 6) noticed the grow room is a little humid throughout parts of the day but I will be installing the fan today. Both plants seem to be adjusting well. 4/3/21 - Plants are doing good. Watered them with ph 6 water. Noticing some yellow on the bottom leaves. 4/4/21 - The ends of the leaves are turning a light yellow from nutrient burn as a result of the ocean forest soil. Started low stress training today, added two clips per plant (see photo) 4/5/21 - The soil is still moist from yesterday, I’m not going to water today. They are still in the low stress training clips. You can really see the nutrient burn today. (See video) 4/6/21 - I watered the plants today with water (ph 6). Not much change in appearance from yesterday. 4/7/21 - Plants are looking great, the nutrient burn is starting to fade a little. I will be starting a new week tomorrow. (Continuing with water, and low stress training)

11. Woche, Meth macht sich, die Main Buds werden ordentlich dick, unten die leider nich so ganz 😅, aber soweit sieht es wirklich gut aus, extrem frostig die gute und diese Zitrus Terps.... 🤤mmmh sehr lecker

Week 3 going well. Topped her and doing a bit of lst to her as well hope everything goes well. Week 4 fead her with 25ml off grow auto from living Soils.

19-11-2021: Still 4 weeks left... Buds are starting to swell, I think I have to harvest the Runtz a week earlier. Lowered CO2 to 800PPM. Lowered EC to 1.8. Will replace the water by end of the week. 21-11-2021: Some people suggesting I should use PK13/14... But they are not telling why.. Honestly... I have no clue what it could do for me. Already using Green Sensation from Plagron with clearly says..."When you use Green Sensation you don't need a PK fertilizer, enhancer, booster or enzymes!". So I am just continuing as I do. @Hazeydays... Was just rereading your comment but cannot find any grow diary from you :(. Why do you think I should add PK13/14?You said (3 weeks ago) your ladies are in week 7 and 3 times as big as mine. What do you mean by that? Because I think it is quite normal that plants in week 7 flower are bigger then plants I week 1 flower. Do you have a link to your diary? Thanks in advance 23-11-2021: As you can see some buds seem already to be ready for harvest. Very strange, only 56 days of 12/12 now. (I started counting flower on day 27 of 12/12 so only 29 days of real flower. I was told this might be due to adding Green Sensation too early but I would expect all the ladies would suffer from it then. It is just one. Even the lady which is in the same bin doesn't show any signs of amber trichomes. Very Very strange. 24-11-2021: Buds seem to swell very fast now overnight. Looking and smelling great. Today my fans will arrive so from tonight on they will have some windy conditions I hope.

Week 9, 3-9 October 2025 3-9 Oct - Observed and let the plant grow. Buds continue to develop and swell as it grows toward maturity. The smell continues to intensify as well. A lot of trichomes have developed and the hairs are just starting to turn brown. Because of the plants smaller size, I don’t have to do a weekly reservoir change, it’s more like every 10 days. She just doesn’t consume as much as a larger plant would. - 2 Oct changed nutrient solution - 2 Oct updated feeding schedule - Using reverse osmosis water with EC/TDS at 0 - Adjusting PH to 6.1 daily using GH up/down - Nutrient solution EC 2.1 at 72 degrees F - Light power at 75%, DLI 45 canopy coverage at 18hrs - Using PYPABL, Air Pump, 400GPH That is it for this week. Thanks for the look, read and stopping by.

Buds are still not growing the way I would like. But okay there are plenty of them. Hopefully they are potent.

Looks nice

Amazing told this run 110 grams of bud and 80 grams of shake. An amazing pungent fruity citrus cream cheese aroma eminates out of my cure vault. The high has been described by my friends as a creative uplifting high followed by intense couch lock. The grow itself was a breeze. The only real issues i had in the hydro grow was that i needed to to add cal mag because it was growing so fast and i was using distilled water. I basically did not train my plants other than defoliating to make space for air flow and light penetration. I would recommend this for any first time hydro grower that has a decent amount of space.

11/5 -- They now have 2 weeks of 12/12 under their belts and it's truly been a tale of 3 plants for the past week and a half. GZ2- This one has the opportunity to meet its full potential. It has stretched to give me this beautiful canopy and very few signs of over feed or stress in it. Hopefully she stays this way. Moby- look like it may have been developing some deficiencies. I fed it a few days ago and it seemed to respond well. Some leaves have gotten yellow but the plant is do thick and dense I'm not worried about a few falling off. All in all, it's been steady eddy for Moby Dick that I now believe is also a Barney's Farm Freebie(the seed is now listed where I buy mine from) I'm not going to change it but if you're keeping track, this is most likely a tent full of Barney's Farm. Gz1- and now the music gets a little more serious. I really started recognizing problems with her right at flip. She has lost a lot of fan leaves due to yellowing,, dark stems and I can tell her branching has suffered because of it. Growth at the bottom looks weak and even wrinkled in some spots. She has burn spots and signs of deficiency galore. But also VERY dark fan leaves. I've just come to the conclusion that flushing was probably my best move. She can still have a week of solid growing. If I can get it corrected now, this plant will still be respectable but the trend is disturbing and alarming to someone who knows how fast they can decline. So in conclusion, things are getting a little hairy. Flowering always brings on a new set of challenges and I'm still learning every single time. Wish me luck this week, I'll need it. 11/6 Updated pic on old friend banana daddy that they shared the veg tent with.

罐子里是之前最顶端的芽，被我烤焦了……

Growing fast

Week 7 of Veg for these beautiful Apple Betty ladies! It was a stressful week for the girls but they made it❤️ Day 44 - I decided the girls had outgrown their 2 gallon nursery pots and were ready to move on. After a quick cleanup of the stems close to the base, they were ready to go. I like to keep my soil in a Rubbermaid bin, either with a fan lightly blowing, or the exhaust line from my tent blowing at it. Since I started doing this, I have not had any gnats or pests in my grows, of course with regular cleanings and IPM…my mix is Promix HP with about 20% worm castings added to it. This time around, I decided to use some Dynomyco to increase the mycorrhiza count of my Promix HP. This will increase root development by adding all kinds of interconnected webbing and allow for better uptake of nutrients overall. Within an hour or so all of the ladies were transplanted ❤️ x2 in 7 gallon fabric pots, and 1 in a 5 gallon fabric pot ( the 5 gallon will finish in my 2x4 tent) Once the girls bounce back and take hold of their new forever pot, I will be setting up my custom “floating” SCROG net and allowing them some time to get bent and tucked all nice snug before I flip to a flower schedule. Happy Gardening ❤️🇨🇦🌱😎

Eccoci qui... Tutto va per il meglio, questa settimana si inizia a vedere la resina e ora si inizieranno a formare le cime, per questo aggiungo Sugar Shot di @xpertnutrients vedremo l'evoluzione settimana prossima. Odore intenso e molto profondo, colore verde scuro non presenta carenze tutto al top. Si va diretti nell'ultima fase della coltivazione. Grazie a tutti per il supporto🔥🌲❤️
