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.

Finaler Grow-Report – Lemon Cherry Gelato Mein erster legaler Grow mit Lemon Cherry Gelato von Barney’s Farm ist fast abgeschlossen – das Curing läuft noch, aber es ist Zeit für ein Fazit zum Anbau! Setup & Bedingungen: Ich habe in einer Spider Farmer 90x90x180 cm Growbox unter der Spider Farmer SF-G3000 (300W LED) angebaut. Als Medium kam BioBizz Light-Mix zum Einsatz, gedüngt wurde mineralisch mit Advanced Nutrients (Grow, Bloom, Micro). Um das volle Potenzial der Pflanzen auszuschöpfen, setzte ich auf Low-Stress-Training (LST) und ein ScrOG-Netz zur optimalen Lichtverteilung. Keimung & Wachstum: Die Keimung verlief problemlos – 4 von 5 Samen sind innerhalb von zwei Tagen aufgegangen. Während der Vegetationsphase entwickelten sich die Pflanzen kräftig und reagierten gut auf das Training. Die ScrOG-Methode half, ein gleichmäßiges Wachstum und eine bessere Lichtnutzung zu erzielen. Blüte & Ernte: Nach etwa 6 Wochen Vegetation leitete ich die Blütephase ein. Die Pflanzen zeigten eine starke Harzproduktion und eine beeindruckende Farbgebung mit einer Mischung aus dunklen Grüntönen, lila Highlights und frostigen Trichomen. Das Aroma war von Anfang an fruchtig und zitronig, mit phänotypischen Unterschieden in der Intensität. Die Ernte fiel mit 300-350 g trockenen Blüten sehr zufriedenstellend aus – für meinen ersten legalen Grow ein starkes Ergebnis. Curing (still in run ): Aktuell lagern die Blüten in 24 Mason Jars (16oz) und einem 2L-CVault, um das Aroma weiter zu entwickeln. Derzeit dominiert eine zitronige Note, während die erhofften Kirsch-Terpene langsam stärker hervortreten. Mein Ziel ist es, die Haze-Noten möglichst gering zu halten und das volle fruchtige Profil herauszuarbeiten – der Prozess ist also noch nicht abgeschlossen. Fazit: Ich bin sehr zufrieden mit dem Grow – die Kombination aus hochwertiger Genetik, gutem Training und präziser Nährstoffversorgung hat sich definitiv ausgezahlt. Die Buds sind harzig, aromatisch und vielversprechend, und ich bin gespannt, wie sich das Curing weiterentwickelt. Der nächste Schritt ist, das perfekte Terpenprofil zu treffen – und das Curing geduldig zu optimieren.

Holky dozrávají ??💣💣 Co k tomu řict přátelé a se daří ať to roste všem 🌱🍀?😎💚

Took some clones from the bottom last week, they're blowing up on top.

Harvest done, plant is drying. 116 days from seed: 51 days veg + 65 days flora

Good week

here we are Guys, 11th week, 6th into flower, the girl is recovering nicely. she started to put some size buds and pistils are started back to grow white. the Led is working perfectly and the buds are really frosty as fuck. I hope she will still give me some nice weight even with the past big mistake. UPDATE: she's definitely recovering fast. at day 82 the buds are swelling, I apologise for all the colors shades but i changed lights in order to get the best shots.

Steady progress this week. Her trichomes have put in an appearance this week! 😎 Still got a way to go yet.

Stretch iz Active

I changed position of the lights and the plants to give more space for my cantaloupes and water melons. The cannabis plants are doing great. The VPD has not been spot on and there have been a great heat wave so I ran into a few deficiencies. Nothing i cant handle. All in all very great progress

Hi everyone :-) This week a lot of nice things happened in the flower tent :-) Everyone looks super nice, and is growing stronger and more beautiful week by week 😍👌. The blue cheese smells like a dream ;-) As usual from this variety 👍. The kosher tangie is also very, very tasty 👏🏻. Both got Pk 13/14 this week for the last time :-) Everyone else is developing very well 👍, That will be the last diary with several strains together :-) In future everyone will come individually 👌. I wish you a lot of fun with the videos, have a nice weekend, stay healthy 🙏🏻 and let it grow 😎👌

Gorilla Glue Auto Day 89 This week I continue watering with 1.5 litres of water and nutrients every other day. I continue to remove leaves that are obstructing the flowers. The flowers continue to swell. When I look through the magnifying glass the trichomes are some 50% clear, 50% cloudy, 0% amber. Next week I will change the watering schedule and reduce the nutrients!? Gorilla Glue #4 Week 10

This week was a little rocky. Two girls on the outer edges are good, but the middle one is drooping and foxtailing already. It's weird because my middle plant was larfy last run as well. I might push her to the corner and let her do her thing with less attention... because I just got a photoperiod runtz clone that's gonna need some space and perhaps its own light. LST seems to be going well for the other two though. Sometimes with autos, it's just a genetic thing. They can be temperamental girls sometimes.

I am now putting my weekly comments in the videos. Watch the videos for updates.

It's Day 54 Week 08 0f Flower For My 02 Kombucha Cream by atlasseed . And For My Snow White and SpliffStrawberry by Spliff Seeds Amsterdam . So Today I Started My Day By Checking My Tricomes On My 2 Kombucha Cream. The 02 Where Looking Fully Milky So My 02 Kombucha Cream Got Flushed TODAY with Some Flawless Finish by Advanced Nutrients . The 2 Received 80ml of Flawless Finish mix with 1OGallons Of Water Ph at 6.0. Tomorrow they will get Rinse off with ph balance water. Yesterday I watered my Snow White and SpliffStrawberry Ppm where down to 100ppm. All 4 Plants will get a nice ice bath in a few days. My plan is to check the Tricomes on the SpliffStrawberry In a few more days she was still Milky when I check her yesterday. I will chop her down next weekend. And the rest will get the chop at 30%Amber Tricomes. Happy Growing Growmies 🤘🏻

fail blooming

Week 5 starts with recover from the previous FIMing. I'm surprised 😍 ------ Day 30: Found a better way to LST, the branches are growing much faster now :D Day 34: Sex clearly visible 😁 (female)

Looking forward to Super Lemon Haze finishing.

Humidity too low, I need to get a misting fan.

I veg them for 10 weeks. The two on each end are Blue Dream, the back left is Purple Urkle, the back right is Grandaddy Purple, and the one up from in the middle is Wifi OG.
