Today, on day 57, the plants have gained height and transitioned to the active flowering phase, with their height now around 100–130 cm. Nutrient concentration is 850 ppm, room temperature daytime up to 26°C, nighttime up to 22°C, CO2 concentration up to about 850 ppm, and humidity at 50%. The light schedule is 18 hours of light and 6 hours of darkness. PPFD — 700. Nothing was changed in the parameters. The plants continue to gain mass. They've grown even more. Growth is good, height already exceeds 125 cm. Visually, there are no deficiencies or burns; the bushes are developing very vigorously and absorbing their 850 ppm well without salt buildup. We did defoliation, removed a decent amount of leaves, probably 20 kg wet. We'll send them for extraction. The plants have spread out a lot in width, branches are already closing the passages between tables, jungle 😁. Big rastafari to everyone, Raizap brothers! 😝

this grow stretched a t least an extra week my last 2 grows were ripe in 8 weeks .There re no hermi flowers and its going to be at minimum 9 weeks mabe 10 to get ripe .dont know why it stretched into week 6 of flower when its normally 4 weeks stretching the buds are now getting filled in and solid just have to wait i guess

Hi growers sorry I haven't updated my diary been away on holiday I'm back now and ready to go again. This is day 31 all 3 are growing good they've all started to flower the only problem I have notice since I've been away some of the leafs have started to yellow I've gave them 3 litres of water with 1 ml of big bud , bud candy , rhino skin and 2ml of cal/mag I'm hoping there's enough nitrogen in the cal/mag to turn the leafs back to green I'll update in the next few days I've also cut off a few leafs from the bottoms of the plants. Day 32 quick update all 3 have started to get burn on the tips of the leafs I really didn't want this problem so early on in flower. They have perked up abit but the top leafs are still abit yellow next feed I'm going to add some micro grow and bloom with some cal/mag. Day 34 I gave them 2 litres of water with 2ml of micro grow and bloom the leafs are still abit yellow and I haven't noticed much growth in the last few days I'm hoping there ok I think my pH may be to low with the small branches going purple and the burnt tips I'll update next feed or any problems.

The tallest pheno is ready and being flushed for a couple of days now, rhe others are close but still consuming nutrients at a strong rate , I think they will take at least 1 more week. They smell very much like gelato as a group but are all very different from one another .

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.

Looks like a lot of top sights. Afraid stretching too much. Hopefully it fills in.

Mar 31st Week 16 Changed nutrients to straight Dense Bud Compactor 1 gram/ litres @ 900-1000 ppm for 2 days CR # 1 showing signs of root wrought I removed the slimy parts of the roots and will watch closely On April 2nd I will add the rest of the nutrients to the existing solution April 2nd Fresh nutrients today, all nutrients added 8 litres of fresh water + 6 litres of the existing Dense Bud solution @ 1100 ppm CR # 1 is dying due to root wrought I removed most of the roots today. I changed all the water today with this one. I’m hoping to get it to harvest, but things don’t look good. I will probably flush this soon to harvest what I have. CR # 2 is doing fine as far as roots. Buds are smaller on this one but may fill out more with the Dense Bud Compactor. April 6th Switched CR # 1 to flush solution Root wrought was sever and unfortunately 90% of the root mass had to be removed Time to save what I have

Flowering nicely now. Not drinking a ton of water but I attribute that to lower temps lately.

I'm 2 days early but here's a tent tour, still not sure about the rusty spots but I don't think it's that big a deal. I'm pretty sure lightly feeding with just the bloom booster was a good call. I'll keep doing that untill she matures out. I have spider mites ;-; good thing she is about to mature. I'm going to call 3 more weeks, might chop slightly early if I can't deal with the mites anymore, visibly affected leaves have been removed due to possible eggs

Yo Farmers, in the plant's 11th week, I had to take some drastic measures to keep her healthy and thriving. First off, I did some major defoliation by plucking a ton of her fan leaves from the lower and middle sections. That way, she could get better airflow and light penetration. It's still not perfect, but we tried. Then, I had to apply some high stress training since the plant was stretching like crazy. It was like she was trying to reach the moon or something. Anyway, during my inspection, I noticed some damage on the leaves close to the light. It could have been from light burn, Calmag issues, or a phosphorus deficiency. To fix it, I adjusted the distance of the light and fed her a high PK nutrient solution to boost her phosphorus levels and nutrient uptake. Gotta keep the girl fed, right? All in all, it was a lot of work, but it was worth it. The plant's still growing strong and looking better than ever.

Week 15 (5/30/22 - 6/5/22) - FLOWER Week 1 Left camping for a week and came home to these lil ladies shooting past the trellis. I pulled them down under the trellis and tried to evenly shape the canopy then defoliated and "shaved the legs" Then flipped to flower on 6/1/22

Added nutrients to top off reservoirs everything looks good …I am content so far with testing will be dropping light schedule to 11 on 13 off to accelerate bud development hopefully shortening flowering time

Week 1 (23-29/01) During this week I will feed the plants with tap water and only 2 ml of Bio-Grow. I will also dimmer the light down to 30% because, being it at 20cm from the plants, I want to avoid burning them. The fan will be on 4 hours/day. By means of the inkbird thermostat I will control the heating/cooling system. Inkbird parameters will be: 23.5°C with -3°C for heating and +2°C for cooling. 23/01 D1: preparing the pots. A layer of gravel surronded by light-mix by BioBizz. Planted the three sprouts. 24/01 D2: added a support to each plant to avoid the fall due to the weight. Provided a glass of fresh water (25cl) to each of them. 25/01 D3: - 26/01 D4: watering day. Added 2ml of Bio-grow to 1.2l of tap water (approximately 40cl of water each plant). 27/01D5: - 28/01D6: watering day. Approximately 50cl of tap water to each plant. Powered on the fan. 29/01D7: -

July 30, - Last week of Veg from the look of the plant, its heading into flower - plant has had its 1st meal w/ Veg nutes reduced, 2nd meal w/ Bloom nutes introduced. - Next meal posted above. 31st, - branch-bending and some fresh compost on the plant base. (= tv dinner for a couple weeks) Aug 1 - started the day with some LST and the top of this plant is now pretty darn wide and level. Yesterdays bending was well timed. After only 2 LST sessions on the Canopy, its a different more receptive plant heading into Flower - last transition meal fed; 3 gallons. Next meal, its bloom nutes from here on out Aug 2nd - when gentle-bending becomes kinky… the plant looked great after the LST. This morning I saw a great opportunity and it involved More aggressive tactics and saw some more aggressive kinking & super-cropping. - plant had a nice “South-facing” slope. Aug 3 - woke up to a beautiful plant, with a legitimate level canopy. Bring on the Blossoms, Jack is down to 38” again Got rid of the last Sucker in the grow. No touch now lol, what you see is what you get Aug 4 - next meal posted above… - clipped the lower suckers on ea Cola branch to help keep the business on the end

Hey Cannafam, My gals had another wet week, each day has had showers although its not been solid and she has had time to dry out in between assisted by me going out to shake off water after each rainfall. However at the beginning of the week i found what suspect to be start of rot in one of her lower braches as a sugar leaf had died for no reason amoungst a bunch of healthy ones, so that bits had the chop. I also found a cocoon of some sort glueing to leaves together at the top of the plant and had to cut that out, the consistancy was of latex and i think it was a moths or buterfly. Needless to say ive been inspecting her dayly closley for any more issues. On the positive side of things shes holding up quite well currently, all bud sites are building even the bottom branches which were exposed last week are starting to fill out. Smell has increased again and this gal is absolutely honkin now. In terms of feeding shes just had one dose this week, there is a tiny bit of burn on some of her leaf tips and shes a light feeder. The weathers looking drier for next week so she should be catchin more rays and lovin life again. Thats all from me, thanx for stoppin by 😊💜💜💜

She was very easy to grow, structure of the plant is small and bushy which makes it real good for tent grows. Recommend this strain to anyone growing, buds are dank and real strong
