Leider musste ich mich von einer Lemon O.G. verabschieden. Hermi von unten bis oben in so gut wie jeder Bud. shit happens. 🤷‍♂️

Since I am in DWC and the fertilizers are organic, I take care to add them slowly.. Como estoy en DWC y los fertilizantes son orgánicos, me ocupo de añadirlos lentamente... Por el momento no controlo la atmósfera, sólo tengo un extractor ajustado a 400m3/h para los 2 lumatek al 75%. Planeo controlar la atmósfera a partir de la inyección de CO2 en la semana 2 o 3 para ver más. Mientras tanto tengo algunos picos de temperatura por encima de los 28 pero son realmente específicos. Estoy tratando de mantener la humedad lo suficientemente alta para tener un buen VPD. For the moment I don't control the atmosphere, I just have an extractor set at 400m3/h for the 2 lumatek at 75%. I plan to control the atmosphere from the CO2 injection in week 2 or 3 to be seen again. In the meantime I have a few temperature peaks over 28 but they are really specific. I am trying to keep the humidity high enough to have a good VPD. Subí un poco la ec este fin de semana 4 de 0.9 a 1 I turned up the ec a bit this weekend 4 from 0.9 to 1

09/22/2022 had to harvest early because of but rot, powdery mildew, bud smells incredible, but I had root issues it had very weak root system, probably my fault for starting her so late in season. I will definitely try again in spring, I might get a couple joints off her but not much more. Again I will take the blame for I did not give her a fair chance.

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.

Harvest is imminent! I'm basically just waiting for her to drink her last watering. So 1-3 days I guess - my last few "finished" plants basically stopped drinking much at the end, and she seems to be the same. But my last post was about a week ago so one more flowering week report! A few days ago I took off some of the brittle taco-ified fan leafs. My guess is they don't do much for photosynthesis anymore and just prevent lower growth from getting light. Upper leafs by now have turned a pretty violet/plum color! I put a leaf from another plant in the picture for comparison.😊 Structurally there is little change since last week. Smell is still incredible too! She is significantly heavier than three weeks ago so the stems are losing the battle against gravity.. but as she's coming down in a few I'm not gonna go wild with jojos or garden wire. 🤷

Day 51 - Deficiencies have gotten a bit out of hand the previous few days. Looking at the leaves I was thinking maybe calcium and magnesium deficiency, but it doesn't really make sense to me because I had: 1. Given a decent feeding with the Aptus cal-mag solution. 2. Calcium was already in the soil (pre-fertilized) 3. There is more often too much calcium in soil than too little. 4. There is a not insignificant amount of calcium in the water I use (causes limescale in a lot of things) So my guess is instead of calcium deficiency, I'm seeing next to some magnesium deficiency, a deficiency of phosphorus. So a couple of days ago I gave the plant FloraBloom which has both phosphorus and magnesium but no nitrogen or calcium. Today (two days later), the leaves are now feeling a lot less dry / crunchy, which was a supposed symptom of phosphorus deficiency. I expect to need to wait about two more weeks before harvesting. Maybe around 10 days. The trichomes are still fairly glassy although there's some cloudiness. Pistils are still mainly white though, so I'm expecting some fattening to happen. I don't really like feeding the plants at this point (short before harvest), but the deficiencies were severe enough to me that I'll keep giving FloraBloom this week. Next week I might stop depending on where the trichomes are at. Smell is excellent, I definitely now understand where the 'mandarin' name comes from. Very similar to a mandarin smell now. Other than the phosphorus / magnesium issue, the plants seems to be doing well.

She's becoming a very big lady and the smell it's amazing. A couple more weeks and then it's harvest time . Hope i can provide her a little bit more shelter for if the rain is there. ,,,🍀🙏🌞🤞

07.09.2024 Erntezeit! Ich werde weiter berichten. 31.10 letztes Update mit den Videos.

Grow geht langsam richtung Ende. Leider zu kleine Töpfe benutzt aber was soll man sagen ist mein erster Grow

Una semana mas de vegetación para dar el inicio de la floración, realizamos ciertas podas en las ramas bajas. Se ve un bonito color, además de que se ven plantas sanas y enérgicas!

Empezamos (Día 8) nuestra segunda semana de vegetación de nuestras Sweet Seeds Tropicanna Poison XL. Tienen 13 días de vida desde la germinación y se están regando con un pulverizador con agua de osmosis con CALMAG. Las plantas están creciendo sanas y fuertes y están empezando a desarrollar sus primeras hojas de verdad. Estamos emocionados de ver cómo se desarrollan en las próximas semanas. 👽

My girls are growing wonderfully. Pineapple and Cheese are getting bigger and bigger, and you can start to smell them. Bubblegum has taken its time, but it too is full of resin and will probably be the last of the harvest. I decided to start giving Overdrive to the Skunk to try to add consistency to the flowers, which are still very sparse, and it already seems to be working. This is my first run with Advanced Nutrients and I'm pleasantly surprised!

FBT1 did not like being transplanted at all ! i guess being overwatered stressed her out some, good thing it's early in a way, hopefully she wont be permanently slower 🙏 lol , anyway she's basically healthy now, although last time i watered her it was tuesday last week and now it's friday, medium is still wet though, so no water for her until she dries out some more. Realised i hadnt been spraying my kelp carefully enough the week before so i'm spraying the soil with amino to try to keep pH basically fine until i can water with cal mag and hopefully some co2 enriched water. I pHed down the spray with 0.1g of GHE dry pH down powder to 6.0... rain water is pH 5.5 so i'm okay i think. anyway fbt1 in mrB's so easy i didnt even have to water this week lol. check out the videos, let me know ! 🚀
