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.

Aufgrund der Höhe, habe ich zu Beginn der Woche an der einen Pflanze HST angewendet und den headbud an einer bestimmten Höhe "umgeknickt". Das hat hervorragend gut funktioniert. Allerdings habe ich den abgeknickten Haupttrieb mit einem seil fixiert. Als ich heute nachmittag in das Zelt sah, lag der Trieb neben Topf und war eins a sauber abgetrennt. Das Seil war nicht unter Spannung gezogen, lediglich als Haltepunkt wenn der Trieb sich wieder aufstellt. Nunja er ist jetzt ab. Ausserdem ist eine weitere Pflanze Männlich. So bleiben 4 von 7 die definitiv weiblich sind. Zum Wochenende gibt es ein paar neue Fotos von den verbleibenden Damen. Bis dahin, grow on.

Well, week 11 has started today 8/15. So blessed to have gotten this far! I'll be flipping the lights tomorrow to begin to start flowering. I have both my tents linked up so I don't have to run two separate exhausts! Now that the stress part is over time to sit, enjoy some puffs and continue focusing my energy! Happy growing everyone ✌️🍀✌️ UPDATE: 8/17 Day one of 12/12 in the books! I gotta say, I always chill with my plants before I turn down for the night and it was strange not doing it last night, lol. So I'm gonna get some green lights! I have an awesome app on my phone called Hydroponics Green Screen Light, it's in the app store for free. Developer in Timothy Johns. It works great but not enough for me. But it is great if you need to go in during the dark cycle for whatever reason. Or you can get yourself a lamp and a green grow room bulb! Happy growing everyone ✌️🍀✌️ UPDATE: 8/19 Everything is looking very good. Got some very noticeable growth! That's about it really. Happy growing everyone ✌️🍀✌️ UPDATE: 8/21...just uploading a few pics to end the week with. Well 12 and the start of 2nd week of flower begins tomorrow! Everything still looking good 😁 Happy growing everyone ✌️🍀✌️

Aquí seguimos, separamos ya los machos y nos quedamos con 5 hembras de las 9 que seleccionamos. Más del 50% muy contento. Durante estas 2 semanas hemos estado luchando contra una pedazo de plaga de mosquitos que hemos sufrido. La cosa parece que mejora pero habrá que estar muy atentos. La floracion va en camino podría ser mucho mejor pero la plaga ha hecho sufrir a las plantas. Iremos actualizando. Buenos humos.

Well all these ladies had a major growth spurt. My lights are at the max height now so I hope they are done. Good news though the Gorilla zkittles and Red diesel are showing bud forming, so hopefully I can count on them to be done stretching now. Started them I defoliated pretty good on day 7 I started them on the rhino skin once I got something to keep it turning in my reservoir. I also top dressed 1/2 cup of compost mix and hit them with a light top feed of recharge. Looking forward to seeing these ladies pack on weight in the new few weeks.

The flowering is start😁😁😁 G14 is much higher than amnesia xxl, but both have flowers. I change the light period on 18/6😃

Gradually, Gorilla Cookies begins to extract the nutrients from the leaves. it is impressive how much resin it produces. Hopefully she will do well in the last few weeks.

Beautiful canopy going outta these ladies. Colas and tops galore. Just vibrant ,healthy and full of spunk. Booming through bloom and got there bud structuring well underway. They got treated with Dr zhymes as a preventative. That will basically wrap up their treatments ...possibly once more with lost coast. Upped the pk intake as they are blooming strong now. Gotta keep those engines well fuelled. Response was stellar. Happy happy happy ladies. Until next update. Happy growing and stay lit fam.

Sorry for the late update. A lot has been going on lately. This girl needs a defoliation once they get home from work which will be probably tomorrow evening so I won't get to that until the following day at the earliest... i hope everyone is doing well, thank you so much to Kannabia Seeds

well, it's exactly 12 weeks :) and my house is full of lemon aroma :) the girl endured really difficult growth, but she coped with everything perfectly :) who followed the growth, you saw that she grew on the balcony for 10 weeks, and she spent the last 2 in the grow tent :) 500 gr wet weight !!!!:) , before putting it in the ground I expected less than 10 g dry yield :D then this growth turned out super well, if it wasn't for my vacation I would have let it grow for about 2 weeks I think. but everything is still very good, I'll go home, fix it and do a smoke review :).

July 20th. 36 days post flip Clones: These things will not stop growing. I should have known with them being landraces but I am super cropping multiple tops every single day to keep the buds off the lights. Interestingly the plants no longer seem to be burning even when they are directly touching these lights. I’ve never grown a plant this resilient in my entire life but shows what nature is capable of. Some clones have a more modern bud structure but one of them has this crazy almost spear like structure going on. Super excited to see how they smoke in a few months. No longer seeing any deficiency’s on any new leaves due to the nutrients last week. Will likely avoid adding anything else except some build a flower here in a week or so. Smell is finally starting to take off. So far very peppery but also a slight off smell as well. Can’t quite put my nose on it but hopefully in a week or so will start to get even more smell. Parents: Parents got topped aggressively a week ago on July 12th in order to keep them small. All 4 are already showing new nodes and recovery. So far they have been in these small fabric pots for 20 weeks with no signs of deficiency. I think the secret to that success has been low power lights limiting growth, no night cycle so the plants cannot develop the roots needed, and the fabric pots air pruning the roots so they don’t ball up. At this point simply going to continue topping every month or so and once they start showing deficiency will move them into slightly larger pots God bless!

I’m really not seeing huge differences,what do u guys think?🤔

This is the whole flowering cyclus posted in one week.

I am busy all weekend, so I wanted to make sure I got something out of the grow (just in case). I might use a good portion of this harvest for rosin and for when friends ask :) That is if the second plant lasts until next week. I cant ask my wife to keep an eye on water, roots, or bud.

Asal got a trim to open up the air flow and a LST to spread the canopy a little more. Thinking I am done with the lateral spread at this point. Benesh got the same treatment. Asman has been taking the hits when I have overdone the LSTing. Thank goodness for masking tape and time to repair!

Sugar cane was very easy to grow with no issues whatsoever. I'm new to growing so they were easy by my standards. It was everything I had hoped it would be, as far as growing and appearance. I hope it will smoke as good as it looks! The aroma is a very mild, sweet smell, but man the frost on these! the Super sticky icky! 🤪 I would have preferred letting these go another week, but had to chop now because of upcoming circumstances. Didn't see the option to put the dried weight in but out of 3 Sugar cane, I got 9.1oz. Taking a hit of just dried Sugar Cane nug, I was surprised how smooth it was even before cure. Pine/gassy taste. A couple of hits and it was a very uplifting creative high. Then a creeper wave came on shortly after..... almost like that feeling when an edible kicks in and you forgot you ate one! Lol. I couldn't believe I was that high from a couple of hits! Two hit wonder stuff right here! This should last me quite a while!

Today is Day 11 in flower since the flipped. They starting to drink more water and I pay attention now to the EC to make sure they have their proper feeding . I got my ppfd set to 60-70% it was sitting at 40 % on the disable.. when I switch to 70% it get hot up in 4 by 4 so I brought it back down to 60 left it there cause room temperature steady at 74-76. I do need to add more fan though. I am working on it plus the reup on nutrition. My grow store finally got Athena I was like oh sh!t lol. Like a candy store to a grown man I’m 28 … growing my addition seeing the plants prosper and end goals beauty . Gotta love it 💯

Things are really starting to smell strong and getting fun. Seeing some frosty Trichomes. Excited!

12cm vertical growth but look how bushy she is! Not quite entered flowering yet, but that's good... More veg time = bigger plant 😍
