Moved the rest of my autoflowers to my 4x4 tent on 3/21/23 they will be under a 12/12 light schedule until my last photo period plant finishes up

A couple of days ago I got home and a sublime smell of coffee pervaded the area. Smell it smells you I came to understand what was good when I started the flush of our wonderful Auto test #1. The colors have come out forcefully both in the hair and the leaves have taken on a fantastic color, the maturation at the top is practically finished at the bottom something is missing, the plant still drinks a lot and we are flushing as if there were no tomorrow. We don't know what this beauty is GHSC mouths are rightly kitchens because it will be out very soon we are sure of one thing, a smell of coffee that makes me tear my underwear, wonderful. Auto test #2 is a week late but because I planted her quite later, she has now started to apply color but she has been throwing resin everywhere for a while, she too will be scary. There is a lot of good seed bank but only one is of the King. https://greenhouseseeds.nl/ Love this Farm! https://www.mars-hydro.com/

One of them is falling behind but thats prob because of the fact that she got a few less liters of space in her pot Date: 22.07.2024

I really enjoyed growing this single plant in a small space like a first indoor experience. The end result is not exceptional but it is fully acceptable for the setup and the period in which the plant has grown. I very soon hope to bring more serious diaries to really start having fun.

Hola a todos!! Esta semana prácticamente no he fertilizado, ya que luego de un breve lavado note que los valores de ppm aun seguía siendo alto..(1700...1800), entonces segui regando solo con agua, con bajas ppm 500 ppm aprox. Recien ayer logre bajar las ppm , no asi el ph, del drenaje, me viene dando 7.2, pero a pesar de todos estos inconvenientes, a la planta se la ve engordando los cogollos.En esta semana se estiro 4 cms solamente, pero los cogollos están creciendo de buena manera. El lavado lo hice el día 44 con 7 litros de agua con ph 6 y ppm 500, luego de un buen rato de drenaje medi y en ese entonces parecían haberse corregidos, pero al siguiente riego dia 46( lo hice con 2lts de agua) me volvió a dar valores altos. Para no generar un mal ambiente para la planta, la deja descansar 2 días, y ayer (dia48) volvi a regar y al fin las ppm han bajado a 900, el ph aun sigue dando alto, pero como mencione antes la planta demuestra que cualquier inexperto la puede cultivar, porque se aguanta todo ese stress😅😅 . He notado que esta cepa, tiene notas como cítricas, es un olor rico🤩🤩🤩🤩.

Six weeks ago I flipped the light to 12/12 and I got to say it’s pretty fast growing. Trichomes looking good. Harvest get closer and closer. 4 of 5 plants are colouring pretty hard. Nice bud to leaf ratio and overall nice appearance. This week I started to lower the temps for terpene preservation. Smell is quite skunky and a little bit fruity.

This week marks the final phase of flowering for both strains, and it’s been an incredible run. The colas are fully swollen, trichomes are mostly cloudy with around 10–15% amber, and the terpene intensity is off the charts. Every movement near the canopy releases that unmistakable scent — fruity, spicy, and heavy with resin. 24K Gold is showing her signature golden hues now. The buds are compact, sticky, and sparkling with trichomes. Pistils have mostly turned orange and curled in tightly, showing clear maturity. Gelato 33 looks equally stunning — thick, frost-covered buds with a creamy-sweet scent and purple undertones emerging under the lights. Her structure remained open enough to prevent mold despite the high density. Both plants handled the last nutrient increase (8 ml/L Canna Coco A+B) perfectly — no signs of stress or nutrient burn. From here, they’re transitioning into the flushing phase, allowing the remaining nutrients to fade out for a cleaner, smoother finish. Environmental conditions: • 🌡️ Temperature: 25.0–25.3 °C • 💧 Humidity: 52–53 % • 🌫️ VPD: 1.3–1.34 kPa • 💨 Airflow: Steady and dry for the final days This week’s update also includes defoliation and trimming before drying — the canopy has opened up nicely, and the buds are ready for harvest. The next entry will focus on flushing, fade, and drying results.

1 week left until i flip, the blue dream and white runtz are lagging behind but the pineapple express, and ghost train are begging for flower! day 54, and what a beautiful first grow it has been so far, these girls have responded well to all the punishment i could dish out in training and have responded with a beautiful even canopy. cannot wait to see them flower day 55, midday, lights are off for the next 36 hours to expedite the flowering process.

I am going to start my new week 24-11-2019 because the soil is telling that it needs water and it's technically the beginning if the new week so why not. If you look at the still Pic the leaves look like a deficiency or maybe light burn I did not notice that earlier today. I have si ce raised the light and I will check tomorrow to see if the color of the leaves have turned green all through the veins where there is some signs of yellowing. If I see change the maybe both concerns have been addressed because I also increased the ppm's in feeding.

Week 8 Pure water feeding

Views expressed are my own. All opinions are my own. The opinions expressed here belong solely to me and do not reflect the views of Growdiaries or Grandcru Genetics. 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.

After 48 hours, these things are beast. I thought they needed more time, I couldn’t judge how long they were. I had to dig them out of the paper towel, learned that I need to use cheaper paper towels. 6 out of 6 germinated on my first grow. Let’s keep the same growth going. ******************************* 14 Hours After Potting ************** TEMPS The most recent video showing the domes is 14 hours after potting them. The temps have been very stable at 83F and 70% humidity. My ambient temp outside of the tent is 70F. AIR FLOW I’m currently only running a 6 inch fan above the light for circulation. I have not used the exhaust, I think the idea at this stage is to keep humidity high, any thoughts would be great. LIGHTNING I do have my TSW on max and lowered the height to 36 inches it was almost twice the height yesterday. I didn’t want to make the change so drastic and waited a bit before lowering the height. WATERING The top soil did feel a bit dry and a little moist under. Under the dome it still looks very moist. I sprayed the plastic domes, I’m using distilled ph’d water. I did some light watering on the soil but I’m not sure how much water I should be using . Now that I lowered the height soil should dry out quicker, any thoughts?

Just flip the light schedule to 12/12. Reverse osmosis watering ph 6.2

Hello and welcome growmies & friends👋....Another slow week for me and the girls most of the workload i fought with the moisture in my basement where my grow room resides and the size is 140x142 centimeters 16.08. I add Jungle Indabox: A: 25ml. B: 75ml. M: 50ml. x: 25ml. Hesi Power Zyme: 115ml. Canna Cal Mag: 50ml. Canna PK12/13: 80ml. AtaBloombastic: 25ml. Ata Clean: 3ml PH: 6,18 EC: 2,8 18.08. Killer Kush #4 shows probable signs of Cal Mag deficiency but in case i drop in some more nutes, she looks like she needs it...the girl # 4 is about a week late in flower compared to the rest. I add Jungle Indabox: A: 20ml. B: 70ml. M: 50ml. X: 20ml. Canna Cal Mag: 70ml. Atami Bloom: 20ml.. PH: 6,25 EC: 3.2 20.08. Girl #4 still shows something like i think Cal Mag deficiency but all the other Killer Kush plants already have dark green leaves so i add only: Canna Cal Mag: 45ml. Canna PK12/13: 80ml. As of today all the plants look healthy, I'm dropping my first video in the next weeks there will be more to watch, at least i hope so. In the video i made a mistake at the begining describing the right side the left one....sorry for that, will try to do a better job in the future. That's it for this week I hope everyone had as good a week as i did, hopefully see you next week ...all the best to you my friends and keep it growing.💪

Nice buds growing :D I’m quite impatient ! I will put PK at the 30th 35th day I wait the buds bigger ! I do defoliation a lot and every day it’s insane how it grows every day ! I pinched the apex of the plants which I didn’t cut the apex.

The S.O.1 gets still only Water and calmag. I love how she turns purple now…I dont know is it about the Pheno Or that I did something right or wrong but i love it. The s.0.2 get now biobizz like plan. She is the biggest one with the Most Buds but also the smallest at all. S.0.3 is about Day 65 and i think my Favorit with S.0.1 I think the 1 one only Need one more week but the other two about two or three. I’m more than happy about my first grow ever and will run this strain again as my second run to get better Can’t wait to harvest woohoo

Gorilla Cookies Auto - Fastbuds And 2 random Cookies and Cream seeds Very excited for this new grow SF1000 ~40% ; 30 cm Germination GC on 09.01.2023

Wow look at her grow we are in the second week of her flowering stretch and she looks amazing. Smells good already omg super excited about this one ☝️🏽
