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 girl looks really good, strong thick branches, which I wanted to bend a little more, but I don't have the space for that :D :D The girl hasn't started to show her flowers yet, but I think that in a few days, it should appear :) good luck to everyone.

Day 66 ... the weather get´s more worst too cloudy and cold at night 😱😫😵... so i decide to harvest today 😃👍 Now "Hilde 2.0" is hanging in the dark in the basement and can dry... I'm curious to see how the harvest turns out 😃🙌🙏

Mit den Criticals bin ich voll und ganz zufrieden bis jetzt aber die Northern lights lassen ein wenig auf sich warten 👀

Hoping they finish their flower stretch this week, snoopy and hazel are pretty tall already and my tent won't support much higher. Branches are getting tougher to lst as they grow. Other than that, looking great. My goal for this grow is 150 grams, so on average about 38 per plant. As long as I hit 100 grams I'll be happy though (Day 39) glad I did more lst because Snoopy and Hazel are growing 5cm a day. Thea (bottom left) has stayed pretty small compared to her sisters, as a result she has only been able to claim a small corner in the tent, she's furthest in flower regardless though. (Day 41) starting to look like Hazel might actually become the biggest plant, her stem is way thicker than any of the others. She's also the least far in flower and working on her sidebranching

😫Been a tuff week as my ph pen failed so had signs of defiantly But that’s now corrected so hope it didn’t set them all back too much

This week wss giid. She grow good and she shares a pot with my wedding cake. I let she grow a week or two and send her to flower. Have a nice week everyone and thanks for visiting my diary🙏✌️✌️

A mini plant pink rose, brazil haze regular. Bad pictures, but in 12 weeks is quite full develop, and window opens till 22 weeks, the plant seems non stop flowering. Slow blomming. Can have many branches. In my experience wit thag landrace if you cut apical gem, will grow a lot ramifications but for being a organic its hard recover and slow so will prolong flowering and give more disperse buds. For me the main lining its good and buds can get more dense. Great flexibility. Organic flower manure, worm cast, sea shells, ashes of soil. Magnesium mineral added in some veg times after one month.

Still doing foliar: Cal-Mag Terra Aquatica, Pro Bloom, and silicate from T.A. some plants are removed because of root root. naw left with 19/24 plants. I also use a mobile app to set the light intensity, and I burned the leaves later. Which gave me the knowledge that the application is not very accurate.

I switched over to 12 and 12 four days ago.i went out and bought the net so I'm about to get my Scrog on.i really don't have a lot to say.everything has ran smoothly.my ppm is kind of high but nectar of the gods is pretty gentle as long as you go by the feeding schedule. i have been feeding with my line up every other other feeding.then it's fish shit and herculean harvest and ph ro water to 6.4.

Die Blueberry wurde getoppt hat ihr gut getan der Training

She's really starting to fill out nicely now. She's now in flower beast mode. Her trichome production has definitely been stepped up also. She also started to get her cheese funk.

Day 5 of Starting my biggest grow yet. All seed are from fast buds and are prizes from nov 22 newbie of the month. Iam starting this grow now as I have worked my way to getting a setup I am happy with. Will try to keep a detailed run at this dairy. Iam Biobizz light mix substrate in 12L root nurse fabric pots under two mars hydro ts1000s running at 25%. Average temp 20c and humidity 80% this week. Got three healthy seedling my Cherry cola don’t look to good I will germinate a seed along side her this week and see how we go. Let’s get this work 💪🏽💪🏽💪🏽

DIA84 Buenos buds, uno de los mejores aunque piden siempre alguno que otro nute. Rastafarah.

🌱 Germination Journey with Terpyz Mutant Mentha de Croco 🌱 Hey Grow Fam! Today kicks off an exciting adventure with Terpyz Mutant Mentha de Croco genetics. I’ve got 10 regular seeds ready to sprout, and I’m looking forward to discovering some beautiful female phenotypes—and maybe even a standout male for potential future breeding. It’s been a while since I’ve worked with regular seeds, so I’m thrilled to dive in! Germination Process Overview: Here’s a step-by-step rundown of the germination setup and process, with a special focus on the equipment and nutrients that are helping these seeds thrive right from the start. Step 1: TheCannaKan Germination Pod 🌱 For germination, I rely on TheCannaKan—a device I’ve come to love and trust. It’s designed to create the perfect microclimate for seed germination, and within just 24 hours, the seeds started showing signs of life. By the 32-hour mark, they were all ready to be transferred to the next stage! I can’t recommend this gadget enough for anyone serious about getting strong, early growth from their seeds. • Why TheCannaKan? • Humidity Control: Ensures seeds stay hydrated without oversaturation. • Stable Temperature: Maintains an even temperature around the seeds, so there’s no shock or stalling. • Enhanced Oxygenation: Keeps fresh air circulating, helping prevent mold and ensuring seeds don’t suffocate. Step 2: Transfer to Root Riots & Aptus Holland Supplements 💧 Once the seeds were sprouted, I transferred them into Root Riots, known for their excellent water retention and structure that encourages strong root growth. Root Riots also have a pH-balanced, spongy texture that makes it easy for roots to penetrate, promoting sturdy, healthy root systems. At this stage, I started using Aptus Holland’s Regulator and Startbooster at 1ml/L each. Here’s why I chose these products for early growth: • Aptus Regulator (1ml/L): Helps strengthen the plants against environmental stresses by supporting cell wall structure. It’s a fantastic choice for giving young seedlings an early boost in resilience. • Aptus Startbooster (1ml/L): This product provides essential microbes and nutrients that stimulate root growth and early plant vigor. Especially for regular seeds, the early root development makes a noticeable difference in later growth stages. Step 3: Lighting with Future of Grow (FOG) LED at 200 PPFD 💡 For lighting, I’m using a Future of Grow (FOG) 600W LED. For the germination stage, I’ve dimmed it to around 200 PPFD (photosynthetic photon flux density), which provides just enough light for healthy, strong seedling growth without overwhelming them. • Why Low Intensity? • 200 PPFD ensures that young plants aren’t exposed to too much light, which could cause stress or stunting. This level of intensity is perfect for encouraging healthy development without risking “stretching.” • The FOG LED provides a balanced spectrum tailored to plant growth, setting up these young sprouts for success as they grow. Step 4: Environmental Control with TrolMaster Tent X Controller 📲 For monitoring and control, I’m using the TrolMaster Tent X Controller, which lets me dial in every aspect of the environment to make sure these little ones have the perfect conditions for germination and early growth. • TrolMaster Benefits: • Precision Control: Adjust temperature, humidity, and lighting all in one place. • Notifications: Sends updates in real-time to my device, so I can make adjustments as needed without being physically present. • Consistency: Maintains stable conditions around the clock, reducing stress on seedlings and ensuring they’re thriving. Grow Tips & Reflections: Germination is one of the most crucial stages in a plant’s lifecycle. Starting with strong genetics like Terpyz Mutant Mentha de Croco, combined with a solid germination setup and the right nutrients, creates the foundation for a successful grow. 💡 Quick Tips for Fellow Growers: • Hydration Balance: Don’t oversaturate! Moisture levels should be high enough for the seeds to sprout but not so wet that they drown. • Light Management: A low PPFD for young seedlings prevents stretch and keeps nodes tight, preparing them for a healthy vegetative phase. • Environment Consistency: Use a reliable controller like the TrolMaster Tent X to manage your settings, and consider monitoring tools for real-time adjustments. Shout Outs to the Community: Big thanks to Terpyz Genetics for these incredible seeds, Aptus Holland for their top-notch nutrients, Future of Grow for the stellar LED lights, and TrolMaster for the amazing controller. Also, shout out to all of you in the growing community—you make this journey exciting and filled with endless learning. Let’s keep growing and sharing together! That’s it for the germination update! Next up, I’ll be monitoring growth closely to identify strong females (and maybe a standout male for breeding).

Diese Woche kam endlich mein Luftbefeuchter von AC Infintiy an, habe die Luftfeuchtigkeit gleich mal auf 75% hochgeschraubt, ich denke in der aktuellen Phase habe ich noch kein hohes Risiko mit Schimmer. Ich werde die gleiche Luftfeuchtigkeit noch in der vierten Woche halten und danach suggestiv um 5% pro Woche runter gehen. Außerdem habe ich diese Woche eine halbe BTI Tablette auf 10l Wasser eingesetzt um die Trauermücken ein bisschen unter Kontrolle zu bekommen. Außerdem habe ich Reismilch angesetzt, selbige werde ich morgen mit Milch mischen, dann einige Tage warten und dann die daraus resultierende Milchsäure als Zusatz für das Gießwasser zu geben.

June 13th - Day 22; fed 1L yesterday 16th - fed a full meal; 1L - extended another section of LST. It can now grow as it wants 17th - taking some urgent action because of an ailment that had fallen on Californian Snow, that now seems to be affecting Zamaldelica. After being fed yesterday, Cali Snow had all of her Fan Leaves wilt and dissolve sort of, within 4 hours. She was flushed and it seems a Low pH was the final element to clear from the run-off. This morning Zamaldelica fan leaves are sporting Orange Spots. I’m throwing 6 gallons of pH’d water (6.5) through the substrate right now thanks… ! - looking to put some of the blame on me, for allowing these plastic pots, with limited holes, to be the final resting place for these gems… should have AT LEAST been into Fabric or Smart Pots DoH. When I picked them up yesterday, that container was physically Hot. Not dry, but man the soil portion was warm. - glad I flushed, did not see this one coming. Sure, it was a Heat Warning, weather system, but things did not dry-out. - also moving Zamaldelica into a 5 gal fabric pot. Last soil in the house, kinda worked perfectly. Sorry Californian Snow, maybe too far gone. Something became acidic in the substrate after the volume of that meal, reached the lower levels, and an accumulation of Nutes/additives. It reacted - I knocked off any loose soil from the original Pot/rootball and put 60% of the plants core into a DynoMyco laced 6gal bag. - caption for the video; been one of those days…

Hey guys! I chopped all the top half of the plant on 6/4 21:30 and the bottom half on 7/4 23:00. It’s now the 9/4 at 11:30 all of it sits in jars. Dried quicker than I wanted it to but all the buds were very dry too touch so I jarred them. I figured it was easier to remove moisture from the jars than it is to put moisture back into them so hopefully this plan works out🤞 she has a hay smell to her and I’m hoping this goes while curing her. All the nugs look great and some are mega dense and others are very airy. The more airy ones being from lower down I just didn’t have time to keep her going. She weighed in at 110+ grams wet, But I didn’t weigh any of the lower nugs. Dry weight all combined is 35.8 grams. 9.2g from the bottom half and 26.6g from the top half. I’ll re weigh it once I’m done curing. Very happy with this first grow I wasn’t expecting to have this good of a finish even if it isn’t the best💪 both jars are around 21c, the jar with smaller nugs has been sat at 55%-65% and the bigger nugs are getting up to %70 so I’ve been opening the big ones letting the humidity go back down again. I don’t expect to get the drying and curing done %100 but that’s what the first grow is all about. Roll on to my next 3 plants harvest day😎 I smoked all the material that went through the sieve while trimming and damnnn.. tasted like something out of Amsterdam. If the flowers end up like that I’ll be very happy😁 I’ll be adding a smoke report once she’s ready, really looking forward to it🤣 Id like to give a huge thanks to everyone who has helped and advised me on this journey! I’m taking all the info onto my next grow a lot more confident. My next 3 plants are doing brilliantly so far I’d appreciate it if you’d check them out! Onwards and upwards, stay safe and happy growing everyone! With thanks Ema26😎🍁🌱
