You don't become confident by shouting affirmations in the mirror, but by having a stack of undeniable proof that you are who you say you are, outwork your self-doubt. Nitrogen fixation is a chemical process by which molecular nitrogen (N2), which has a strong triple covalent bond, is converted into ammonia (NH3) or related nitrogenous compounds, typically in soil or aquatic systems but also in industry. The nitrogen in air is molecular dinitrogen, a relatively nonreactive molecule that is metabolically useless to all but a few microorganisms. Biological nitrogen fixation or diazotrophy is an important microbe-mediated process that converts dinitrogen (N2) gas to ammonia (NH3) using the nitrogenase protein complex (Nif).[2][3] Nitrogen fixation is essential to life because fixed inorganic nitrogen compounds are required for the biosynthesis of all nitrogen-containing organic compounds, such as amino acids and proteins, nucleoside triphosphates and nucleic acids. As part of the nitrogen cycle, it is essential for agriculture and the manufacture of fertilizer. It is also, indirectly, relevant to the manufacture of all nitrogen chemical compounds, which include some explosives, pharmaceuticals, and dyes. Nitrogen fixation is carried out naturally in soil by microorganisms termed diazotrophs that include bacteria, such as Azotobacter, and archaea. Some nitrogen-fixing bacteria have symbiotic relationships with plant groups, especially legumes.[4] Looser non-symbiotic relationships between diazotrophs and plants are often referred to as associative, as seen in nitrogen fixation on rice roots. Nitrogen fixation occurs between some termites and fungi.[5] It occurs naturally in the air by means of NOx production by lightning.[6][7] All biological reactions involving the process of nitrogen fixation are catalyzed by enzymes called nitrogenases.[8] These enzymes contain iron, often with a second metal, usually molybdenum but sometimes vanadium.

(Terpenes) Chamomile.(Oil production) Borage.(Pest attraction taste) Lavender.(Pest attraction smell) Marigold(Pest attraction visual) Mycorrhizae are beneficial associations between mycorrhizal fungi and a plant’s root system. Mycorrhizal fungi spores germinate in the soil, creating filaments (hyphae) that penetrate the root cells, thus establishing a symbiotic relationship. This collaboration leads to the development of both intra-radical and extra-radical networks of filaments, enabling efficient exploration of the soil for enhanced access to nutrients and water. Consequently, these vital resources are transferred to the plant, resulting in numerous benefits for crop cultivation. Various mycorrhizal products are available in diverse formulations (powder, granular, and liquid), concentrations, and qualities. Ongoing advancements in products, technologies, and research are reshaping our understanding of mycorrhizae. Despite these positive developments, certain misconceptions persist. In the following discussion, we aim to clarify the truths and dispel the myths surrounding mycorrhizae products. MYTH #1 A HIGHER NUMBER OF MYCORRHIZAE SPECIES MEANS BETTER RESULTS. Contrary to common belief, having a higher number of mycorrhizae species in a product does not translate to better results; in fact, it often yields the opposite outcome. A plant can sustain only one association with a particular mycorrhizal fungi species. Introducing multiple species creates competition among them, which is not advantageous for the plant. The initial colonizer does not ensure the highest success; instead, it gains precedence. It is recommended to select a product with a concentrated presence of a single mycorrhizae species known for its effective performance, rather than opting for a product with multiple species at lower concentrations. MYTH #2 ECTOMYCORRHIZAE ARE EFFECTIVE FOR CANNABIS PLANTS. Although ectomycorrhizae can colonize five to ten percent of plant species, cannabis is not among them. Ectomycorrhizae do not penetrate the root cells; instead, they develop around the roots and on the exterior. For cannabis plants, it is essential to seek out endomycorrhizae. Endomycorrhizae are capable of colonizing 70% to 90% of plant species, including cannabis. Unlike ectomycorrhizae, endomycorrhizae penetrate the root cells, forming structures like arbuscules for the exchange of nutrients and water with the plant. MYTH #3 WHOLE INOCULANT (PROPAGULES) PERFORM BETTER THAN ONLY VIABLE SPORES. The propagule count specified on most mycorrhizae products indicates the presence of spores (viable and unviable), hyphae, and root fragments. However, it is crucial to note that only viable spores, those with the capacity to germinate, can successfully colonize a plant’s root system. Spores are to mycorrhizal fungi what seeds are to cannabis plants—a fundamental component enabling fungi reproduction. Consequently, even if a mycorrhizal product boasts millions of propagules, its effectiveness hinges on the presence of viable spores. Without viable spores, the product will not contribute to plant development. Therefore, the genuine value of a mycorrhizal inoculant lies in the quantity of viable spores it contains, as only viable spores can efficiently initiate symbiosis. MYTH #4 ALL METHODS OF APPLICATION YIELD IDENTICAL RESULTS. To establish the symbiosis, mycorrhizal fungi spores must be close to the plant roots. The optimal recommendation is to directly apply mycorrhizal inoculant to the roots, either in powder, granular or slurry form. This method ensures maximum proximity between the spores and the roots, facilitating a rapid establishment of symbiosis. Particularly with crops like cannabis, which have a short growing cycle, employing this technique is the most effective way to obtain optimal benefits. Alternatively, techniques such as blending the inoculant with the soil are effective, but there may be a delay in the establishment of symbiosis. This is because the roots need to grow and come into contact with the dispersed spores throughout the growing media. MYTH #5 MYCORRHIZAE CAN ONLY BE GROWN ON LIVING PLANTS. While the predominant method for commercially producing mycorrhizae involves growing them on the root systems of living plants (in vivo production), it is not the exclusive nor the optimal technique. In fact, this production approach has notable drawbacks that the “root organ culture” method just does not have (in vitro production). In vitro production occurs in meticulously controlled, aseptic laboratory conditions, allowing for the consistent generation of products that are viable, highly concentrated, species-specific, and free from pathogens. Achieving such precision and quality is impossible when relying on the cultivation of mycorrhizal fungi on plants exposed to external conditions. In conclusion, it is crucial to take all these factors into consideration when choosing the appropriate product for your crop to fully harness the wide array of benefits provided by a high-quality mycorrhizal product. STRONGER PLANT – Stress resistance. FASTER GROWTH – Improve plant structure and shorter veg time. INCREASE YIELD – Overall more biomass. IMPROVED QUALITY – Increase cannabinoids and terpenes content.

Plants with more direct UV showed much more purple across all 3 plants. The data shows that the number of terpenes in dried Cannabis flowers increases with a “No Red” light treatment for the final three days of production. Based upon these findings, we feel confident in recommending a spectrum control program that eliminates red light output from fixtures for the final 72 hours of the Cannabis flowering cycle. Terpenes are aromatic compounds that give cannabis some of its most distinct aromas from citrus and berry, to more earthy tones. Many species of plants produce and emit terpenes in a diurnal, or daily cycle that is regulated by a complex web of signaling. There are also many plants that emit terpenes at night to attract nocturnal pollinators (Marinho et al., 2014346). Regardless of when the terpenes are produced or emitted, these processes are often dependent upon cues derived from natural light/dark cycles via a native circadian clock (Dudareva et al., 2004). Several light-sensitive pigments are involved in these processes of production and emission, and the different photoreceptors are dependent upon different wavelengths of light to be activated or deactivated. Emission of terpenes is a process that is entirely dependent upon phytochromes and red/far-red light cues in most plant species (Flores and Doskey, 2015). For example, repeated light/dark phytochrome signaling is necessary for the emission of terpenes in tobacco plants (Roeder et al., 2007). Based on previous findings, we hypothesized that a lack of red light and phytochrome-mediated light/dark signaling on the part of the plant is responsible for an increase in terpene content in cannabis. The plant continues to synthesize terpenes, but a lack of red light to trigger the Pr-Pfr shift results in a lack of terpene emission by the plant, thus causing the terpenes to accumulate in the maturing flowers.

Plant Mol Biol 65: 107-12 Abstract Sound waves technology has been applied to different plants. It has been found that sound waves were at different frequencies, sound pressure levels (SPLs), exposure periods, and distances from the source of sound influence plant growth. Experiments have been conducted in the open field and under greenhouse growing conditions with different levels of audible sound frequencies and sound pressure levels. Sound waves at 1 kHz and 100 dB for 1 h within a distance of 0.20 m could significantly promote the division and cell wall fluidity of callus cells and also significantly enhance the activity of protective enzymes and endogenous hormones. Sound waves stimulation could increase the plant plasma-membrane H+-ATPase activity, the contents of soluble sugar, soluble protein, and amylase activity of callus. Moreover, sound waves could increase the content of RNA and the level of transcription. Stress-induced genes could switch on under sound stimulation. Sound waves at 0.1–1 kHz and SPL of (70±5) dB for 3 h from plant acoustic frequency technology (PAFT) generator within a distance ranged from 30 to 60 m every other day significantly increased the yield of sweet pepper, cucumber and tomato by 30.05, 37.1 and 13.2%, respectively. Furthermore, the yield of lettuce, spinach, cotton, rice, and wheat were increased by 19.6, 22.7, 11.4, 5.7, and 17.0%, respectively. Sound waves may also strengthen plant immune systems. It has been proved that spider mite, aphids, gray mold, late blight and virus disease of tomatoes in the greenhouses decreased by 6.0, 8.0, 9.0, 11.0, and 8.0%, respectively, and the sheath blight of rice was reduced by 50%. This paper provides an overview of literature for the effects of sound waves on various growth parameters of plant at different growth stages. https://doi.org/10.1016/S2095-3119(13)60492-X

Hello everyone :-) A lot has happened this week 🤗. It has developed very nicely and its roots have exploded properly 😍. It is also slowly becoming lighter, since it has obviously been slowly consuming its nutrients from the soil :-) That is why it was repotted today, mixing 2 g per liter. soil Green House Powder Feeding Bio Grow between the soil. Then everything was mixed and distributed well, and the plant used. I hope that's the little shortcoming is quickly picked up :-) When watering, 1.5 g of enhancer per liter was added :-) Unfortunately I noticed too late that I didn't take any pictures of the root ball while repotting 🤦‍♂️🏻. I look forward to seeing how it evolves this week. Above all, I am excited to see how she is doing with the Green House Powder Feeding BioGrow , as I have been used to mixing everything for each wash separately 😊. During the course of this week I will also spontaneously decide whether I will give her an LST, topping fimming, etc., since I have to see how I am in the vegi phase, because the Cup has a limited time 😁. I wish you all a lot of fun watching, have a nice week, stay healthy 🙏🏻 and let it grow ☘️👍 .

Folder 10 – Frosted Guava Auto B Week 4 | Vegetation – The Quiet Climber Welcome back to The 8×8 Adventure, a project where twelve unique cultivars are being grown side by side inside the same environment, allowing every genetic to express its own personality under identical conditions. Each plant is documented individually because no two phenotypes tell the same story. Even when they share the same genetics, subtle differences in structure, vigor and flowering behaviour make every diary unique. Frosted Guava Auto B is proving exactly that. Although she shares the tent with her sister, she has developed her own character. Slightly taller, equally healthy, and every bit as determined, she’s entering the next chapter of her life with confidence. Our 12/12-from-seed journey continues, and this week marks another exciting milestone as the first signs of flowering begin to appear. ⸻ 🌱 Week 4 – A Compact Plant With Her Own Personality While Plant B has stretched just a little more than her sister, she remains a very compact autoflower compared to many of the other cultivars sharing this 8×8 room. Instead of investing her energy into vertical growth, she has focused on producing tight internodal spacing, sturdy branches and a surprisingly balanced structure. Looking around the room, it’s already clear that Frosted Guava is unlikely to become one of the tallest ladies of the garden—but height has never been the goal. Sometimes the smallest plants surprise us with the biggest harvests. Her canopy is filling beautifully, each node producing healthy new growth that will soon become flowering sites. Every day she looks more organized, more symmetrical and more prepared for what comes next. ⸻ 🌿 Gentle Training, Natural Development Just like her sister, Plant B has only received gentle Low Stress Training throughout her early life. Rather than forcing the plant into shape, I’ve focused on carefully bending large fan leaves, tucking foliage away from developing shoots and allowing natural light penetration into the centre of the canopy. This subtle approach has encouraged multiple branches to grow evenly without creating unnecessary stress. The result is a plant that still looks completely natural while developing a much more open canopy. Sometimes patience is the best training technique. ⸻ 🌸 Pre-Flower Has Officially Begun This week brings one of my favourite moments of every grow. Tiny white pistils have started appearing throughout the upper nodes, confirming that Frosted Guava Auto B has officially entered the pre-flowering stage. One of the most fascinating aspects of this 12/12-from-seed experiment is watching these autoflowers transition into bloom without hesitation. Rather than waiting for a long vegetative period, they simply follow their own internal clock. Despite her compact size, she’s wasting no time. The foundation has been built, and now the real show is about to begin. Over the coming weeks, I’ll be watching closely to see whether she delivers a modest stretch or stays true to her compact structure while focusing her energy on dense flower production. Either way, she’s looking incredibly promising. ⸻ 🌡️ Environmental Conditions The room continues to provide a stable environment for all twelve cultivars despite the warmer summer temperatures. Environment • 🌡️ Day Temperature: 33°C • 🌙 Night Temperature: 25°C • 💧 Relative Humidity: 63% • ? Substrate Temperature: 21°C • 💦 Nutrient Solution Temperature: 26°C • ⚗️ pH: 6.1 • ⚡ EC: 1.35 mS/cm • ☁️ CO₂: 639 ppm • 💧 Water Consumption: 1.1 litres per plant per day Even with daytime temperatures reaching 33°C, Plant B continues showing excellent colour, strong leaf posture and vigorous growth, demonstrating how well she’s adapting to the environment. ⸻ Feeding Schedule This week’s feeding remained simple and consistent, allowing the plant to continue building healthy vegetative growth before fully committing to flowering. Per litre • Terra Grow — 1.8 ml • Power Roots — 1 ml • Pure Zym — 1 ml • Sugar Royal — 1 ml Adjusted using: • pH Plus — 0.03 ml • Lemon Kick — 0.03 ml The Plagron feeding programme continues delivering exactly what these plants need at this stage—healthy roots, lush green foliage and vigorous, stress-free development. ⸻ 💡 Lighting The entire 8×8 garden continues to thrive beneath the outstanding Future of Grow LED fixtures. Uniform light distribution across the canopy has helped every cultivar develop evenly, while allowing each phenotype to express its own natural growth pattern. It’s fascinating walking through the room and seeing twelve completely different personalities growing under exactly the same environmental conditions. Frosted Guava Auto B is a perfect example of how genetics shape the plant just as much as the environment. ⸻ 🌱 Looking Ahead Week four closes with Plant B looking healthy, balanced and full of potential. She’s entering flower with strong branching, vibrant foliage and a structure that promises excellent light penetration throughout the canopy. While some cultivars in the room are already showing more vertical ambition, Frosted Guava B seems determined to stay compact and focus her energy where it matters most. The coming weeks will reveal whether this translates into dense, resin-packed flowers—but for now, she’s ticking every box. The journey is only getting started. ⸻ 🙏 Thank You As always, thank you to everyone following The 8×8 Adventure. Sharing this project with growers from around the world is one of the most rewarding parts of the journey, and I truly appreciate every comment, question and piece of advice along the way. A special thank you to Zamnesia for providing these exciting Frosted Guava Auto genetics, to Plagron for the trusted substrates and nutrient line that continue supporting healthy, vigorous growth, and to Future of Grow LED for delivering exceptional lighting that allows every phenotype in this room to perform at its very best. Finally, thank you to GrowDiaries for giving this amazing community a place to learn, share experiences and celebrate our passion for growing together. See you all next week, when Frosted Guava Auto B takes another step into flowering. Until then… Growers Love and happy growing! 🌱💚

Hallo und herzlich willkommen zu meinem Growbericht Outdoor 2025 mit den Sorten Power Flower Feminized, Royal Medic Feminized und Special Kush #1 Feminized, alle 3 von Royal Queen Seeds. Es ist das erste Mal, das ich Töpfe für den Outdoor grow verwende, bisher waren alle Gorilla grows und direkt in die Erde gepflanzt. Die URL der Power Flower Feminized: https://www.royalqueenseeds.de/feminisierte-hanfsamen/120-power-flower.html Die URL der Royal Medic Feminized: https://www.royalqueenseeds.de/cbd-samen/148-royal-medic.html Die URL der Special Kush #1 Feminized: https://www.royalqueenseeds.de/feminisierte-hanfsamen/138-special-kush-1.html Die Planung für den Grow ist, die Samen in easyplug Anzuchtwürfeln keimen zu lassen und danach in 0,6L und 2,2L Plastiktöpfen, dann letztlich in die neuen komplett doppellagigen ROOTIES 15 Liter Wide Version Stofftöpfe umzutopfen. Sobald die Witterung es zuläßt, sollen die Pflanzen an die frische Luft. Es ist schon eine Weile her, das der Grow losging, die Bilder sind jetzt aktuell. Tag 211: Für heute waren 20°C vorhergesagt, tatsächlich steckt die Sonne hinter dickem Hochnebel und es sind gerade mal 14°C. Heute Nacht geht's mit 2 °C Richtung Gefrierpunkt. Alle drei Ladies purpeln im Laub. Sie bekommen nur noch pures Brunnenwasser. Der abgebrochene Ast der Special Kush ist wieder komplett angewachsen. Wenn's dir gefallen hat, schau wieder vorbei ✌️😎

📆 Semana 7 La Papayton de 42 Fast Buds sigue su evolución espectacular. Los cogollos se vuelven más densos y pesados, cubiertos de una resina brillante que resalta cada detalle. Los tonos grisáceos se mezclan con matices rojizos, creando un contraste único que anuncia la madurez avanzada y un carácter muy definido. Las ramas laterales siguen sosteniendo con fuerza el peso floral, mientras la reducción de hojas permite que cada cogollo luzca en todo su esplendor. El aroma tropical se intensifica, dulce y afrutado, impregnando el espacio con notas exóticas y envolventes. La formación de tricomas se acelera, presagio de una floración potente y llena de brillo. 🌸 La planta sigue demostrando equilibrio y vigor, acercándose a su punto álgido con una energía contagiosa. ¡Seguimos creciendo fuerte 💪!

Hello. This is the end of week 9 and I'll be harvesting in a few days. I figured out why plant #2 has so many yellow and dead leaves.... 50% of it trichomes are amber It's done. The plant could have been cut down at 8 weeks, but who knew? This is the test to find out. 😉 The other 2 plants aren't quite as far along as plant #2... So it will work out. So I'll change my plans and cut them down in a few days, after a couple of days of dark These plants have great smells. It sweet and sorta desert type of smell with some musk and citrus hints thrown in. Back in a few weeks with the harvest report. OK. Keep growing Straight. Chuck.
