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.

Permant marker the one seedling I could not be more happy with. It has a distinct different look to it than any other plant in the tent with strong growth going on. I'm sad about the other seedling thou the 1st set of leaves were kinda deformed and it has like a spiral thing going on where new growth comes from. Hopefully it comes back around, I always like seeing atleast 2 phenos of a strain I feel it gives you a better idea of what a strain is. It's looking like a good start to a week the plants are strong they are getting to the point I can let the dried dry out completely. I'm thinking by the end of this week the plants will be starting to be sold. Last week I put all the plants into my bigger 2x4 tent with my medicgrow mini sun 2 the 500w version. Only a few of the plants were ready for that light. Seems like the only plants that really have good resistance and have a strong start are the weedseedsexpress.com seeds. Shout out to weedseedsexpress.com for the strong plants. I ended up putting all the plants back into my 2x2 tent with the 55w amazon light it has alot more blue light in its spectrum. It's kinda weird b4 I switched the plants to the 2x4 tent they were getting 220umol under my amazon 55w led then when I put them under the 500w light 25% strength about 50in from plants and they were getting only about 195umol in that tent but it was stressing most the plants. I assume a larger light has more side lighting hitting the plants. I think when useing larger lights it's good to measure umols from the top but also coming from the sides. I think durring seedling stage they only need about 50% the umols coming from the side the plants as the top is receiving. When I put the plants back in the small tent about the same umols as they were getting b4 the switch and they were still a little stressed. So for a few days I put the small light at the top the tent giving them 100umols for a few hrs then 130umols the rest the day.

Sono nate tutte e già sono pronte per crescere in maniera abbondante. Dopo una settimana già sono dieci centimetri alte e tranquillamente si stanno adattando al caldo estivo italiano. È stata una germinazione perfetta e sono felice di avere scelto queste magnifiche banche dei semi mondiali. I cloni invece hanno preso bene e sono già posizionati a terra all'aperto e posizionati in penombra. Alcuni cloni non c'è l'hanno fatta ma più di nove cloni sono in perfetta salute e hanno iniziato a radicare. La pianta madre dei cloni è una Orange Bud raccolta indoor in gennaio e poi trasferita in outdoor per farla rigenerare e ad inizio aprile ha iniziato una seconda fase vegetativa abbastanza mostruosa perché sta formando centinaia di diramazioni biforcute e sta prendendo la classifica forma di cespuglio grezzo. Ne vedremo delle belle con queste varietà coltivate biologicamente. Un abbraccio a tutti.

……during the last 3 growths, I worked to mix the best foundation. I think I succeeded 😊 …..it is a mix of coconut, light mix of biobizz and organic nutrients that I tried to harmonize into the best that I can provide to the plants in my modest conditions. How? simply by observing all the growths and looking for the right setting, creating nature in the growing room.

Week 4 | Glookies Auto Decision made. After three weeks of side-by-side comparison, one plant clearly outperformed her two siblings in vigour, structure and overall development. The other two have been discarded, and the winner has now moved outside — straight into a 12L airpot, bottomless, set in the garden next to the 46 Kush. **RootX** was applied again at this transplant, delivering mycorrhiza (*Glomus intraradices*), *Trichoderma harzianum*, 13 strains of *Bacillus spp.*, humic acids, amino acids and vitamins straight into the new root zone — giving her the same strong start outdoors that got her through the indoor selection phase. Last recorded indoors before the move: Week 4, height 18cm, light schedule at 17 hours, EC 1.5 mS/cm, pH 6.2. Now she's outside and adjusting to natural light and the elements. She's settling in well, leaves looking healthy and well-watered. Updates every Sunday. Stay tuned.

On the grow itself, I just got twice as much yield with 1/3 fewer plants by switching to coco and CocoTek, I would count that a win. Zero stress so I was right, grow them without stress and you will be rewarded. Just the easiest best smelling little plant to grow. Always germs well and produces long as you treat her right. It loved the CocoTek and Soul Peak finisher FIVE STARS ON BOTH add them to the list GD! If anyone needs help growing in coco coir get this book! Coco for Cannabis - MJ Coco https://www.amazon.com/Coco-Cannabis-Growers-Dr-M-J-ebook/dp/B07G9LR4W2/ref=sr_1_1?crid=LYSB5G978Y1I&keywords=coco+for+cannabis&qid=1579029394&sprefix=coco+for%2Caps%2C267&sr=8-1 1/20 Absolutely the best grow yet for potency, dont want to guess but it's at the strains upper limits I am thinking from the effect.

Hi Growmies, She has been taking very well to the plant success Orca that I have been feeding her for the last 7 days. Root development just exploded. Since these results are quite impressive I will definitely include such a product in my feeding plans. She doesn’t really want to stretch properly, even with an elevated and dimmed light. So I decided to flip her yesterday and am expecting at least 15-20 cm stretch. The Rezin I started feeding has already shown it’s effect as well, with small trichomes starting to appear on the fan leaves already, long before pre-flower has even started. Thanks for stepping by and until next week. Thanks for stepping

no signs of pests during the grow. only one time i had ants trying to infest one plant but easily got rid of them by using cinnamon around the stem. she grows easy and is fun to train, you don't have to be an expert. in the late flowering i got some budrot in both plants and stalled the harvest by inspecting and cutting it away daily, haven't lost a lot due to it. i would recommend this strain as she is a high trichome producer, big yielder and easy to grow plant that gives nice buds with a good smell and greath high. she is a strain that makes you talkative, giggly and euphoric and is surely gonna give you a good sleep. be sure to go easy on her as she is a strong breed. an amazing strain to grow. she creates colourfull purple buds filled with trichomes that is really good for the chilling occasions, be sure not to have to go somewhere as she will last long and prepare for a joyfull evening with lots of laughing and good talks. i'll post more pictures after the drying process!
