Woop happy with how the grow is coming along had fun trimming the girls down shitting myself at the same time though😝 still on an 18/6 schedule as I didn’t want to over stress the plants following defoliation and scrog . Scrog setting up wasn’t too bad hope I done it right 😅 the screen is slowly becoming very green haha .. I’ll keep looking around on the web to widen my knowledge but for now it seems all is good my plan is to switch to 12/12 starting week 6 and around this time I should look into adding bloom to feed the autos as I’m sure they’re in pre flower stage right now but if ever in doubt I shall ask Some cool photos to look at as well Happy growing ☠️

Yellow butterfly came to see me the other day; that was nice. Starting to show signs of stress on the odd leaf, localized isolated blips, blemishes, who said growing up was going to be easy! Smaller leaves have less surface area for stomata to occupy, so the stomata are packed more densely to maintain adequate gas exchange. Smaller leaves might have higher stomatal density to compensate for their smaller size, potentially maximizing carbon uptake and minimizing water loss. Environmental conditions like light intensity and water availability can influence stomatal density, and these factors can affect leaf size as well. Leaf development involves cell division and expansion, and stomatal differentiation is sensitive to these processes. In essence, the smaller leaf size can lead to a higher stomatal density due to the constraints of available space and the need to optimize gas exchange for photosynthesis and transpiration. In the long term, UV-B radiation can lead to more complex changes in stomatal morphology, including effects on both stomatal density and size, potentially impacting carbon sequestration and water use. In essence, UV-B can be a double-edged sword for stomata: It can induce stomatal closure and potentially reduce stomatal size, but it may also trigger an increase in stomatal density as a compensatory mechanism. It is generally more efficient for gas exchange to have smaller leaves with a higher stomatal density, rather than large leaves with lower stomatal density. This is because smaller stomata can facilitate faster gas exchange due to shorter diffusion pathways, even though they may have the same total pore area as fewer, larger stomata. Leaf size tends to decrease in colder climates to reduce heat loss, while larger leaves are more common in warmer, humid environments. Plants in arid regions often develop smaller leaves with a thicker cuticle and/or hairs to minimize water loss through transpiration. Conversely, plants in wet environments may have larger leaves and drip tips to facilitate water runoff. Leaf size and shape can vary based on light availability. For example, leaves in shaded areas may be larger and thinner to maximize light absorption. Leaf mass per area (LMA) can be higher in stressful environments with limited nutrients, indicating a greater investment in structural components for protection and critical resource conservation. Wind speed, humidity, and soil conditions can also influence leaf morphology, leading to variations in leaf shape, size, and surface characteristics. Small leaves: Reduce water loss in arid or cold climates. Environmental conditions significantly affect gene expression in plants. Plants are sessile organisms, meaning they cannot move to escape unfavorable conditions, so they rely on gene expression to adapt to their surroundings. Environmental factors like light, temperature, water, and nutrient availability can trigger changes in gene expression, allowing plants to respond to and survive in diverse environments. Depending on the environment a young seedling encounters, the developmental program following seed germination could be skotomorphogenesis in the dark or photomorphogenesis in the light. Light signals are interpreted by a repertoire of photoreceptors followed by sophisticated gene expression networks, eventually resulting in developmental changes. The expression and functions of photoreceptors and key signaling molecules are highly coordinated and regulated at multiple levels of the central dogma in molecular biology. Light activates gene expression through the actions of positive transcriptional regulators and the relaxation of chromatin by histone acetylation. Small regulatory RNAs help attenuate the expression of light-responsive genes. Alternative splicing, protein phosphorylation/dephosphorylation, the formation of diverse transcriptional complexes, and selective protein degradation all contribute to proteome diversity and change the functions of individual proteins. Photomorphogenesis, the light-driven developmental changes in plants, significantly impacts gene expression. It involves a cascade of events where light signals, perceived by photoreceptors, trigger changes in gene expression patterns, ultimately leading to the development of a plant in response to its light environment. Genes are expressed, not dictated! While having the potential to encode proteins, genes are not automatically and constantly active. Instead, their expression (the process of turning them into proteins) is carefully regulated by the cell, responding to internal and external signals. This means that genes can be "turned on" or "turned off," and the level of expression can be adjusted, depending on the cell's needs and the surrounding environment. In plants, genes are not simply "on" or "off" but rather their expression is carefully regulated based on various factors, including the cell type, developmental stage, and environmental conditions. This means that while all cells in a plant contain the same genetic information (the same genes), different cells will express different subsets of those genes at different times. This regulation is crucial for the proper functioning and development of the plant. When a green plant is exposed to red light, much of the red light is absorbed, but some is also reflected back. The reflected red light, along with any blue light reflected from other parts of the plant, can be perceived by our eyes as purple. Carotenoids absorb light in blue-green region of the visible spectrum, complementing chlorophyll's absorption in the red region. They safeguard the photosynthetic machinery from excessive light by activating singlet oxygen, an oxidant formed during photosynthesis. Carotenoids also quench triplet chlorophyll, which can negatively affect photosynthesis, and scavenge reactive oxygen species (ROS) that can damage cellular proteins. Additionally, carotenoid derivatives signal plant development and responses to environmental cues. They serve as precursors for the biosynthesis of phytohormones such as abscisic acid () and strigolactones (SLs). These pigments are responsible for the orange, red, and yellow hues of fruits and vegetables, while acting as free scavengers to protect plants during photosynthesis. Singlet oxygen (¹O₂) is an electronically excited state of molecular oxygen (O₂). Singlet oxygen is produced as a byproduct during photosynthesis, primarily within the photosystem II (PSII) reaction center and light-harvesting antenna complex. This occurs when excess energy from excited chlorophyll molecules is transferred to molecular oxygen. While singlet oxygen can cause oxidative damage, plants have mechanisms to manage its production and mitigate its harmful effects. Singlet oxygen (¹O₂) is considered a reactive oxygen species (ROS). It's a form of oxygen with higher energy and reactivity compared to the more common triplet oxygen found in its ground state. Singlet oxygen is generated both in biological systems, such as during photosynthesis in plants, and in cellular processes, and through chemical and photochemical reactions. While singlet oxygen is a ROS, it's important to note that it differs from other ROS like superoxide (O₂⁻), hydrogen peroxide (H₂O₂), and hydroxyl radicals (OH) in its formation, reactivity, and specific biological roles. Non-photochemical quenching (NPQ) protects plants from damage caused by reactive oxygen species (ROS) by dissipating excess light energy as heat. This process reduces the overexcitation of photosynthetic pigments, which can lead to the production of ROS, thus mitigating the potential for photodamage. Zeaxanthin, a carotenoid pigment, plays a crucial role in photoprotection in plants by both enhancing non-photochemical quenching (NPQ) and scavenging reactive oxygen species (ROS). In high-light conditions, zeaxanthin is synthesized from violaxanthin through the xanthophyll cycle, and this zeaxanthin then facilitates heat dissipation of excess light energy (NPQ) and quenches harmful ROS. The Issue of Singlet Oxygen!! ROS Formation: Blue light, with its higher energy photons, can promote the formation of reactive oxygen species (ROS), including singlet oxygen, within the plant. Potential Damage: High levels of ROS can damage cellular components, including proteins, lipids, and DNA, potentially impacting plant health and productivity. Balancing Act: A balanced spectrum of light, including both blue and red light, is crucial for mitigating the harmful effects of excessive blue light and promoting optimal plant growth and stress tolerance. The Importance of Red Light: Red light (especially far-red) can help to mitigate the negative effects of excessive blue light by: Balancing the Photoreceptor Response: Red light can influence the activity of photoreceptors like phytochrome, which are involved in regulating plant responses to different light wavelengths. Enhancing Antioxidant Production: Red and blue light can stimulate the production of antioxidants, which help to neutralize ROS and protect the plant from oxidative damage. Optimizing Photosynthesis: Red light is efficiently used in photosynthesis, and its combination with blue light can lead to increased photosynthetic efficiency and biomass production. In controlled environments like greenhouses and vertical farms, optimizing the ratio of blue and red light is a key strategy for promoting healthy plant growth and yield. Understanding the interplay between blue light signaling, ROS production, and antioxidant defense mechanisms can inform breeding programs and biotechnological interventions aimed at improving plant stress resistance. In summary, while blue light is essential for plant development and photosynthesis, it's crucial to balance it with other light wavelengths, particularly red light, to prevent excessive ROS formation and promote overall plant health. Oxidative damage in plants occurs when there's an imbalance between the production of reactive oxygen species (ROS) and the plant's ability to neutralize them, leading to cellular damage. This imbalance, known as oxidative stress, can result from various environmental stressors, affecting plant growth, development, and overall productivity. Causes of Oxidative Damage: Abiotic stresses: These include extreme temperatures (heat and cold), drought, salinity, heavy metal toxicity, and excessive light. Biotic stresses: Pathogen attacks and insect infestations can also trigger oxidative stress. Metabolic processes: Normal cellular activities, particularly in chloroplasts, mitochondria, and peroxisomes, can generate ROS as byproducts. Certain chlorophyll biosynthesis intermediates can produce singlet oxygen (1O2), a potent ROS, leading to oxidative damage. ROS can damage lipids (lipid peroxidation), proteins, carbohydrates, and nucleic acids (DNA). Oxidative stress can compromise the integrity of cell membranes, affecting their function and permeability. Oxidative damage can interfere with essential cellular functions, including photosynthesis, respiration, and signal transduction. In severe cases, oxidative stress can trigger programmed cell death (apoptosis). Oxidative damage can lead to stunted growth, reduced biomass, and lower crop yields. Plants have evolved intricate antioxidant defense systems to counteract oxidative stress. These include: Enzymes like superoxide dismutase (SOD), catalase (CAT), and various peroxidases scavenge ROS and neutralize their damaging effects. Antioxidant molecules like glutathione, ascorbic acid (vitamin C), C60 fullerene, and carotenoids directly neutralize ROS. Developing plant varieties with gene expression focused on enhanced antioxidant capacity and stress tolerance is crucial. Optimizing irrigation, fertilization, and other management practices can help minimize stress and oxidative damage. Applying antioxidant compounds or elicitors can help plants cope with oxidative stress. Introducing genes for enhanced antioxidant enzymes or stress-related proteins over generations. Phytohormones, also known as plant hormones, are a group of naturally occurring organic compounds that regulate plant growth, development, and various physiological processes. The five major classes of phytohormones are: auxins, gibberellins, cytokinins, ethylene, and abscisic acid. In addition to these, other phytohormones like brassinosteroids, jasmonates, and salicylates also play significant roles. Here's a breakdown of the key phytohormones: Auxins: Primarily involved in cell elongation, root initiation, and apical dominance. Gibberellins: Promote stem elongation, seed germination, and flowering. Cytokinins: Stimulate cell division and differentiation, and delay leaf senescence. Ethylene: Regulates fruit ripening, leaf abscission, and senescence. Abscisic acid (ABA): Plays a role in seed dormancy, stomatal closure, and stress responses. Brassinosteroids: Involved in cell elongation, division, and stress responses. Jasmonates: Regulate plant defense against pathogens and herbivores, as well as other processes. Salicylic acid: Plays a role in plant defense against pathogens. 1. Red and Far-Red Light (Phytochromes): Red light: Primarily activates the phytochrome system, converting it to its active form (Pfr), which promotes processes like stem elongation and flowering. Far-red light: Inhibits the phytochrome system by converting the active Pfr form back to the inactive Pr form. This can trigger shade avoidance responses and inhibit germination. Phytohormones: Red and far-red light regulate phytohormones like auxin and gibberellins, which are involved in stem elongation and other growth processes. 2. Blue Light (Cryptochromes and Phototropins): Blue light: Activates cryptochromes and phototropins, which are involved in various processes like stomatal opening, seedling de-etiolation, and phototropism (growth towards light). Phytohormones: Blue light affects auxin levels, influencing stem growth, and also impacts other phytohormones involved in these processes. Example: Blue light can promote vegetative growth and can interact with red light to promote flowering. 3. UV-B Light (UV-B Receptors): UV-B light: Perceived by UVR8 receptors, it can affect plant growth and development and has roles in stress responses, like UV protection. Phytohormones: UV-B light can influence phytohormones involved in stress responses, potentially affecting growth and development. 4. Other Colors: Green light: Plants are generally less sensitive to green light, as chlorophyll reflects it. Other wavelengths: While less studied, other wavelengths can also influence plant growth and development through interactions with different photoreceptors and phytohormones. Key Points: Cross-Signaling: Plants often experience a mix of light wavelengths, leading to complex interactions between different photoreceptors and phytohormones. Species Variability: The precise effects of light color on phytohormones can vary between different plant species. Hormonal Interactions: Phytohormones don't act in isolation; their interactions and interplay with other phytohormones and environmental signals are critical for plant responses. The spectral ratio of light (the composition of different colors of light) significantly influences a plant's hormonal balance. Different wavelengths of light are perceived by specific photoreceptors in plants, which in turn regulate the production and activity of various plant hormones (phytohormones). These hormones then control a wide range of developmental processes.

Hopefully she will produce some tight buds. 5-11-2019 Pump Quit- Not much I can do at this point other than go it as Deep Water Culture. Root mass is to well established to attempt a removal.

Benvenuti amici alla sesta settimana di fioritura della ormai grande BISCOTTI 🍪 di ZAMNESIA 🗿💙 i fiori stanno letteralmente esplodendo 😱💐😍

Hello everyone. We started growing. ROYAL QUEEN SEEDS-Blue Gelato has been delighting us since the first days.

Kinda a rough week, everyone. I’ve been battling the flu all week and my energy is zapped. So firstly I had been growing increasingly annoyed of leaf clawing. I addressed overwatering and started only watering every 4-5 days and the girls responded well. I researched defoliation as much as I could and gave it a go because the plants weren’t getting optimal light. Might’ve overdone it, I’m not sure. Then came lowering the screens to begin scrogging. I’ve read probably every forum and article and looked at dozens of diaries; but it feels like when I’m tying branches to the screen it’s just stacking them on other leaves and blocking more light. I hate my LED, it’s probably only good for one plant. But today one of the bulbs went out, brand new light. I decided to buy a 315w CMH Light should be here next week. Live and learn. Should have done a single plant grow. It’s a new week though it will all work out. 🍁

Day 85 / Flip 46 / 24.3 Flushed them again with EC 0,0 water. EC Drain is now on 0,0. The next step is to let them dry out. Nutrients will get soaked out of the leafs now, which will make them turn yellow. Letting the plant die now with full light power. I'm planning to harvest in 1 week. Grow is running nice,. Plants look super frosty and will even get more in the drying stage now.. yayyy.....:) Day 91 / Day 52 / 30.03 Additional stress with a 48 hours no light stage. harvest will be at 1.

Ich habe rausgefunden was der Fehler in der Woche 1 war. Anfänger Fehler, zu nass…. Einfach zu viel gegossen, Töpfe zu schwer! Seitdem nur 1 mal gegossen mit 50% der angegeben Düngemenge von Advanced Nutrients Woche 2. gewechselt auf MH Lampe 250 Watt, Abstand der Lampe verringert auf ca. 40 cm. Ich habe noch keine aktive Zuluft aktiviert. Die Pflanzen haben sich gut erholt, ich würde sagen das die Entwicklung jetzt normal läuft. Die Klima Bedingungen wie RLF und Temperatur sind optimal. Seit Woche 2 minimale Zugabe an Cal Mag. Da dies der letzte grow mit diesem Setup ist hoffe ich auf eine gute Ernte….. Peace

Hallo zusammen 🤙. Das war es jetzt für sie wir sehen uns in 3 Wochen für den Erntebericht 🤙

Week 17 Last week before harvest. Just let the plants ending the maturation process. Good synchronization between the different strains, selected with an approximate identical flowering period. I want harvesting all the plants at the same time. Flowers are dense, hard and thick, pretty resinous. 4 strains = 4 different smells, 4 different colors….🤩 I flushed consciously and stopped watering 4 days before the harvest day. I turned off the light during 48h, with ventilation on. All is ready for the cut. Date is programmed to the full moon period….why not…🤔 I will trim a little bit the plants before cutting and hanging them in the tent with the same ventilation cycle, no light of course…

This girl started showing her pistils 3 days ago. I amped up her feeding with some extra Budswell Guano. The growth has been exploding pre-flowering.

We think one of these lady’s are being thrown in to flower by me stressing it. I topped it and I think I shouldnt have , They originally got stunted due to environment technicality difficulties / grower error. Humdifier died , power outages the works , all sorts of obstacles have taken place . But we will see this through to the end for, learning and journal purposes. Happy grows

Oh Ya looking good smelling stinky Got some lowers for Fresh Frozen Nug Rince
