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.

At the end of last week, finally flower indicators started to show and these week it went more. Day 32: I sprayed them with Rhizotonic this week. This will be the last week for sprays. I don't like to spray my plants while having buds on it even thought it is organic. Always make sure you spray from below the leafs. They will uptake it better and also spray some above. With the lights off. Did some defoliation again and removed some lower internodes which will be crappy buds anyways. Made a video of my feeding bucket as well, in case some of you wonder how I feed all those plants manually. It is a pump with an gardenhose attached. Thats it for this week, Until next week!

Finally got some videos up (I think)! One shows the canopy, the other gives an idea of the training under the screen. Shes finally showing signs of female and pistils are popping out like crazy. Decided to not tuck the final days of the stretch so the buds won’t start in the screen and start right above it, seems like I’d be easier come harvest time

CRAZY NIGHT (continued) So apparently frontdeskgirl is pissed that NX left and is saying shes coming back to the hotel (she knows which rooms he has booked) Im just trying to eat breakfast and watch naked waitresses serve the bacon, and now we gotta race back to the hotel whilst calming down frontdeskgirl. We settle up, leave generous tips, and cab back to home base. We arrive to find Jon and Stephanie 2 missing, Stephanie 1 still passed out. The other 2 werent missing long, we found them fucking in the nearby stairwell. Under a security camera, so that was nice. They didnt have a key to get back in the room once they had left to smoke a joint, so they just fucked in the hallway. Got em in the room, and it wasnt 5 minutes before a knock at the door : "security!" Never good at 6am in a hotel room DIARY STUFF Coming in strong this week, these fast finishing photos are on the final stretch. Various percentages of amber coning out daily, waiting till about 30% Nutes are eliminated, running straight ph'd water and the fall colors are coming about. Looking forward to a chop very soon, and the harvest reports to follow.

Chopped down 4 plants that was ready have to chop the rest Tuesday most will be ready like 3 4 will be premature but nothing I can do have to move house Tuesday is latestest can leave em hope they blow up by then lol update got 14 and a half oz from first 4 plants it’s nothing like any stardog I’ve ever seen it’s more like a diesel a fruity diesel it’s very nice to smoke all ready couldn’t resist lol not to impressed with the bud structure bit airy so should hit the numbers I wanted but not to sure yet about the quality right now I’d give it a 7 at best

This week #2 has fattened up a fair bit. Earlier in the week I tried a technique called backbuilding which I never heard of before which involves snipping of the very top of bud growth late in flower to encourage fat buds rather than stretchy ones. Left a couple as they were to compare. I am giving this one plain water from now till the end. #1 is progressing. The bottom of the plant has totally disappeared haha, hopefully the GHE nutes will save the top. Due to lacking nitrogen during its extended veg period which I wasn't planning for; thought it would start flowering anytime! Looks a lot more frosty than #2 did at this point. Should be a good harvest none the less considering how it has had the top cut off and the deficiencies.

Outside all the time 🌞 Day 86: looking good and watered again, it's still really warm right now 🌞. Watered with rain water and 1ml/l Powerzyme, 1 ml/l Hesi Boost, 1 ml/l Cal Mag, 1 ml/l Alg a mic and 1 ml/l Green Sensation. EC at 1.6 and a pH of 6.4 . Looks Like the Last week for her Day 88: developing nicely👌🏻 Not long anymore Day 90: watered with rain water and that's IT🌞 Day 91: looking really nice 🤗 did nothing today 👌🏻

Some of the leaves are yellow/ brown. Did a bit of research, looks like soil might be dry (especially due to high temps during this time of year) and possibly leaves being burnt by sun. Watering with a little bit more volumes of water, based on extra heat. Will track and see how week goes. The 2 bad fan leaves which looked really bad, I cut them off. Increase in volume of water for plants really helped due to really hot temperatures. Week 10 no nutrients (only used on 1st day and 2nd day of week 10) , just straight water.

I love the strain the smell it’s so good and the flower is beautifully

Day 53 and the second candy kush is done

This one was super big and made me super happy. Green crack probably is one of the best strains from classic old school Perfect morning strain Brilliant vibes and emotions all the time Best antistress

Well i ran into some problems, water temps too high over the weekend (i wasn't there) but roots and plant still looked healthy despise 24,5°C water temp over 2 days. I added 2,5ml each Hydro A & B on day 15. EC rised to 0,89 / PPM 445 and two days later ppm still the same i guess because the only part of the root touching the water couldn't uptake any nutes because of the high water temp? (everything above the water looks healthy af tho) Since my apartment is usually really hot in the summer i bought a TEC peltier water cooler + pump and a thermo regulator to ensure the water temps will stay between 20 and 21°C. i just need to wire that up and diy saved me me a lot of money. i payed about 100€ and have automatic temperature control and a cooler from amazon about 200+ € so i think its fine. I'll show you the set up once it's completed and works. Its the best budget cooling i could get my hands on imo. Today is Day 19 my parts came and i really managed it to half ass wire shit and not burning down something. wish me luck. I payed a total of 93,22€ and now got a really quiet, 150w DIY Peltier/TEC) cooler that automatically turns on once the water temp hits 21°C (69,8F) and stops when hitting 20°C. So far its working REALLY well. like im amazed and so proud i managed to do that and it was pretty easy. i had big problems with temps in my attic flat and water temps quickly rising to 24° and more which means root rot. Since i use the cooler all new roots just looking healthy as fuck. the plant is growing well and i see every day progress. So i saved a shit ton of money. the cheapest water cooler i could find on amazon was around 350+€. Sure it bet it works better, is safer to touch, not very likely to cause burning down my house because i had to twist copper wires together and let 230V run trough it BUT no way i have that much money for things like that. The cooler cools water temps from 21,5° to 20° in about 15minutes. the longer it runs the better it cools. i bought a temperature controller outlet ( 25€) which let me set 2 temps and it turning the cooler on and off. I had to cool it down manually every 2 hours before with frozen water bottles💀 So here are the stats for day 19: Water Temps: 20-21°C / pH: 5.42 / PPM: 485 / EC: 0.96 / height: 2,5cm (lol) (i added some more Hydro A and B because i thought i maybe see some nitrogen deficiency) i bet i will see some RAPID growth now since everything is dialed in, hopefully lol 150g im coming!

Well this girl has the making of being a great provider she is strong and resilient being left in a little container for to long .. she was transplanted today on day 23 of her life and she is loving it all ready there will be some good growth now . The light cycle is down to 20 hours and the nutrients are 1/2 strength but not frequent enough . Looking forward to next week's growth and some LST training cheers canna family

The Gorillaz zkittlez (on the left) start to be really sticky. And smell like zkittlez... One of them has some really Orange pistils. The blue sherbet x purple punch (on the right) is a little bit slower. Less trichromes, less smell. Bud the bUds start to be nice as well. As the brand suggests at the 4 week of flowering I add 5grs/L of guano for flowering stage on the top of the soil. No pk booster this time for watering. Maybe I will put the minimum amount of power feeding booster the next watering.

Fruity aroma all over. This run came out better than i expected even though she took some abuse. Drying with herbnow dryer.

Overall everything is doing great. The Cream & Cheese CBD+ has medium trichome coverage and medium density. But she is the bushiest with the most amount of sugar leaves down the stalks with the buds. I think I'm about a month away from harvest. I'm not going to rush it, but that's what my guess is for now. Fed MegaCrop and CalMag this week as well as just straight water.

RQS propagator doing its job. Golden GOAT was the first strain to show her stem. Was recommended by a friend who smoked it before and loved the taste!

Beginning of week 4 in flowering and everything is coming along quite nicely. plants are loving there Remo nutes! just switched this tent over to a self watering drip system cause it was getting to be a real pain watering these girls by hand. Their siting in 7 gallon fabric pots and boy do they drink a mad amount of water/nutes! the pots are just packed with roots! really loving the Remo lineup of nutes so far! go Remo! Go Sports! Buds are starting to form nicely! Started to open up the bud sites a bit by tucking what i could but had to snip a few leaves up top to open a few lower sites up trying to get through.

Weekly update on these three. They'll be getting the chop this week as they're super close to being finished. I'm looking for mostly cloudy trichs on them. Over all Happy
