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.

It’s going okay been battling spider mites tho but I’m praying that I kept them from getting in my flower tent 🤞🏼👏🏼 But other then that everything else is going okay

This week have been all about making sure the bud sights get enough light and enough water. They drink rapidly now compared to the first 10 week of its stage. Very happy with the result i didnt expect to do so well with that many bud. So i am happy with this still and still as excited as i were in the start of the grow. I learned to be more patients with plants. I am planning on harvesting in week 17-18. This will be bombass weed i can see and smell it. Smells like a candy shop every time i open the tent :D

Day 44. Some girls have a bit too much N, leaves show very light curl and some girls are still in veg/preflower mode, so for two waterings it will be phed water with light CalMag added. But anyway, all took that heavy training easy and are blooming. Now i understand in what an absurd grow i created myself, but ... a journey is a journey and i like it ! ;))) Day 45. All good in the Neibourhood ;))) Day 47. Girls got a winner pedestal ;))) had to lift some, had to leave some on the ground, had to supercrop one skyscraper , she was going to the sealings ;)) Still light N overdose curl, but only on one most running to sun strain, so it will be a challenge to feed those 5 pots with other 10 girls in them ... Oh well, hope SOMEBODY will learn ;))

Good week goign from strength to strength. Introduced pk 13-14 at half dosage to start.

Welcome to the Zamnesia Spring Cup 🏆. Hey everything together 🤗. This week has continued to develop super 👍. It was topped for the first time 3 days ago. I think I will not use LST this time because of the short time that remains 😅. Maybe I will do it a few more times top 😁. The Monster Bud Mix also seems to be working, they're pretty dark. They are a little too dark for me , but I will see that in the coming days. Otherwise there is nothing great to report for this week. I wish everyone a nice week, stay healthy 🙏🏻 and let it grow 🌱.

Week 5 - This's first week for flowering. I choose the nutrient for flowering It's 🌎Earth Juice - SeaBlast Bloom.🌿This week the plants are growing very fast.

The ladies are still doing great and stacking very nicely! The trichomes on both pheno’s are insane, super dense buds too. The leaves do look very very dark green with slight tip burns, so I dosed down the nutrients slightly from 1100+ to 950 ppm. The grow light makes the leaves look more light green than they actually are (check the night shots). Both plant smell super super sweet, not really blueberry (yet) though.

This thing just doesn't stop growing so, I'm experimenting, fired in a scrog net and I'm gonna veg it out to fill a 1.5x1.5 net, 1 plant... Should be fun if it actually is a female lol... . . More pics will be uploaded shortly as I'm just back from a holiday. The journey continues..... Plants starting to fill the scrog in nicely, I'm hoping and praying that this remains a female and doesn't hermie as it was originally purchased an auto how ever, I sexed some cutting which sprouted white hairs rather than mini sacks or nanas so, I'm remaining positive as the smell from this plant is insane, the resins coming through the stocks are sticky and have a lovely aroma also. . . Approaching the end of the week and the Gorilla is filling the net nicely 👌.. Fingers crossed now that it turns out a Fem! Pray for me lol...

Mango Kush – Week 4 Flower (Week 8 from Seed) The bulking begins: pistils, stacking, and balanced nutrition Grower: Dog Doctor Strain: Mango Kush (Pheno #1 & Pheno #2) Environment: 8×8 Grow Room Control System: TrolMaster Tent-X brain + WCS substrate sensors (The ThinkRoulette ecosystem) Lighting: • ThinkGrow Model One • ThinkGrow ICL-300 (x2 inner canopy lights) • Future of Grow Black Series 600W • Lumatek Zeus 465W Compact Pro ⸻ 🌸 Week 4 Flower – Bulking Mode Activated Week 4 is an important checkpoint in any bloom cycle. The Mango Kush sisters are no longer just “in flower”, they are now building flowers. Pistils are everywhere, thick and vibrant, forming the foundation for what will become dense, resin-packed buds. Both phenos are looking strong: • Pheno #1 – More advanced, pistil clusters stacking into early budlets, filling her frame with confidence. • Pheno #2 – A little behind, but catching up fast. She may have taken longer to flip (since she germinated later), but she’s now pushing out strong, healthy white hairs that signal the start of her bulking stage. This week’s studio and improvised studio photos capture this perfectly—the transition from “flower set” to flower building. ⸻ 💧 Feeding Update – Simplifying for Strength This week, we made an important nutritional adjustment: • Removed: Aptus All-in-One Liquid & Aptus Top Booster • Kept: • Aptus Regulator – 0.15 ml/L • Aptus CalMag Boost – 0.25 ml/L • Plagron Power Buds – 1 ml/L • Plagron Sugar Royal – 1 ml/L • Plagron Green Sensation – 1 ml/L Why this change? At this stage, the super soil’s NPK balance (nitrogen, phosphorus, potassium) is already strong enough to sustain healthy growth and flower formation. Adding the All-in-One Liquid or Top Booster would risk redundancy, too much nutrient overlap can actually slow the plant down, cause salt build-up, or push her into unnecessary stress. By keeping only the boosters and biostimulants, we are: • Supporting flower stacking and density (Power Buds). • Enhancing terpene and resin production (Sugar Royal). • Adding a multi-function bloom enhancer (Green Sensation, famous for its late-flower results). • Maintaining structure, transport, and stress resistance (Regulator). • Keeping calcium and magnesium in check (CalMag Boost). 🌱 Educational takeaway: Week 4 is about controlled nutrition, not force-feeding. Too much input can overwhelm plants; the art is in balancing what the soil already provides with just enough supplements to guide the plant’s energy toward flowers. ⸻ 🌡️ Environment – Stability Matters The Mango Kush girls continue to thrive under the TrolMaster Tent-X + WCS ecosystem, giving live readings of: • Soil moisture (watering when ~19–20%) • EC levels (tracking buildup) • Temperature & RH (still peaking high at times, but stable airflow keeps the canopy safe) The ThinkRoulette ecosystem (TrolMaster + lighting synergy) has been running flawlessly, creating a stable and responsive environment. This consistency is what allows the girls to focus their energy on bulking rather than on fighting stress. ⸻ 💡 Lighting – Canopy in Harmony The four-light setup continues to shine as a perfectly balanced orchestra: • ThinkGrow Model One – Deep canopy penetration. • ThinkGrow ICL-300s – Mid-canopy energy, no sites left behind. • Future of Grow Black Series 600W – Spectrum balance. • Lumatek Zeus 465W Compact Pro – Evening out the footprint. Result: The canopy is even, pistils are popping from top to bottom, and no part of the plant is left in the dark. ⸻ 🌱 Genetics Check-In – Mango Kush in Mid-Flower Mango Kush (Mango × Hindu Kush) is famous for her fruity-sweet aroma with earthy Kush undertones. Week 4 is where the genetic potential starts to show: • Bud structure is beginning to define itself—rounded calyx clusters forming the early shape. • Aroma is still light, but brushing against the plants gives faint hints of fruit and spice. • Phenotypic difference: Pheno #1 is flowering earlier and faster, while Pheno #2 lags a week behind. This may result in staggered harvest windows, giving two slightly different expressions of the same strain. ⸻ 🔮 What to Expect & What Not to Expect ✅ What to Expect in Week 4–5: • Noticeable bud bulking. • Rapid calyx development, pistil clusters getting denser. • First trichomes appearing under macro view. • Water demand increasing steadily. • Early terpene hints becoming stronger week by week. ❌ What Not to Expect Yet: • Full aroma profile (that comes around Week 5–6). • Major resin frosting (Week 5 onward). • Final bud density or color changes (those happen in later bloom). Educational takeaway: Patience is key. Week 4 is about building structure. The “icing” (frost, density, aroma explosion) comes later. ⸻ 🔄 Recap So Far – The Journey • Weeks 0–2: Seedlings established with Aptus Start Booster. • Weeks 3–4 (Veg): Pheno #1 stretched tall, Pheno #2 filled out compact. • Week 5: Flip to 12/12 → stretch begins. • Week 6 (Flower Week 2): Bloom boosters introduced, lights upgraded. • Week 7 (Flower Week 3): Clear flower set, pistils everywhere, irrigation system added. • Week 8 (Now, Flower Week 4): Bulking stage, pistils thick and abundant, nutrition simplified, environment stable. ⸻ 🙏 Gratitude To the community—thank you for following along, for sharing knowledge, and for keeping the love of cultivation alive. These reports are more than just grow logs, they are learning tools, and together we’re documenting the journey of two Mango Kush sisters from seed to flower. And to the gear, the TrolMaster, the ThinkRoulette ecosystem, and the full lighting orchestra, you make this possible. Technology doesn’t grow the plant, but it empowers the grower to let the plant reach her full potential. ⸻ 📸 This week’s highlight: Studio and improvised studio shots capturing the moment where flower set becomes flower build. ✨ In short: Week 4 Flower is the week of foundations. The pistils are thick, the flowers are forming, and the stage is set for resin and density in the weeks to come. 📲 Don’t forget to Subscribe and follow me on Instagram and YouTube @DogDoctorOfficial for exclusive content, real-time updates, and behind-the-scenes magic.

With true love comes happiness. Always believe in yourself, and always do things expecting nothing and with an open heart. Be a giver, and the universe will give back in ways you could never imagine. 💚 Growers love to all 💚 P.S. – Pheno #1 vs. Pheno #2 A quick note on the sisters’ timelines: • Pheno #1 remains ahead—already deep in flower, stacking pistils fast and showing more advanced bud formation. • Pheno #2, while it started later, is catching up beautifully. Her pistils are now bursting and forming thick clusters, but she still sits a bit behind her sister. This difference is natural: Pheno #2 germinated later and is effectively running on a slightly younger internal clock. The 11/13 light schedule (11 hours on, 13 hours off) means she is easing into flower at her own rhythm. 👉 What this means: Both plants are thriving, but don’t expect them to bulk or finish at the same exact time. This staggered development could actually be a gift—two harvest windows, two terpene expressions, one journey. Educational takeaway: Even seeds from the same strain can flower on different schedules. Rather than forcing uniformity, let each phenotype tell its story. Patience reveals the full genetic spectrum. 🌿 Grower’s Note “This week felt like the real beginning of bloom. The room is alive—white hairs, bulking pistils, and that early whisper of aroma that promises so much more to come. Pheno #1 leads the charge, Pheno #2 follows on her own time, and together they remind me that growing is not about control, but about partnership. The plants teach us patience, and in return, we give them care.”

LSD journey September 15, 2021 day 3 first day of vegetation temperature 27c light schedule is 18 hours of light. I moved my grow light up 16 inches from the pot. September 17, 2021 Day 3 of vegetation Temperature 28.5 I took the plant pot out of the clay pebbles and put it on the top so that it can still get water but I’m not over watering it. 🙏

Got fertilizer burn, had to flush them. Things are looking better but I think they are stunted a bit for sure. 😣

Hey, diese Woche ist jetzt der 2. Monat für die Großen Pflanzen und ihnen geht es gut. Hat sich nicht viel verändert außer das die Buds langsam großer werden. Sie haben schon ca. vor einer Woche mit dem strecken aufgehört. Ich geben ihnen momentan ca. 2l Wasser aller 3-4 Tage. Ich habe auch ein paar mehr Bilder gemacht zum besser betrachten 🔍. Ich denke die beiden Purple Punch werden ca. in 2-3 Wochen fertig sein aber das schaue ich mit dem Mikroskop wie die Trichome aussehen 🤔, die anderen brauchen sicherlich noch 4-6 Wochen wenn nicht sogar noch länger aber das ist kein Problem sie können sich ruhig Zeit lassen 🧑🏽‍🌾. Die 4 neuen Pflanzen 🌱 wachsen sehr gut und schnell, sind jetzt knapp 2 Wochen alt. Ihnen gebe ich nur 1l normales Wasser (pH:6,7), ich denke in ca 1-2 Wochen kann ich das erste Training beginnen. Das war’s für die Woche von mir, over and out

Wow does she smell like exotic island fruit! She exudes ripe mango with dank earthy undertones. I feel like Im on a luxury island resort. Just straight paradise. I could stick my nose in her jar for days. I would rank this close to fastbuds blackberry kush in irresistible smell but she is still untouchable. She smokes just like she smells in the vape. Strong exotic juicy fruit with flowery undertones. The smoke doesnt even smell like weed out of a bong/bowl. I walked back into my room after a smoke sesh and it smelled of silky flowery perfume still hazed in the air. The bowl/bong really exemplify her flowery taste qualities too. Strong energetic high but at the same time I wouldnt mind lying down and hugging a pillow in pure comfort. Thankfully I bought 3 of these seeds.

The funky one has the biggest new growths coming out of the nodes this is week 6 some ph damage from acccaidental un Ph neem mix that I use I forgot to ph but that was about right after the begging of week 5 doing good now looking less ph burned and the new growths are getting big .
