March 13, 2023, at 1:30 PM -I hit the plants with their first treated water on the 11th and lowered the light to 18 inches above the canopy. Today’s the 13th and it’s obvious that the plants are responding. The forum Stomper has really taken off and the blood orange haze number one appears to be lagging. Week one ends on 16 March. Later today I’ll water them with some treated water, hopefully. I’ll take a short video and a couple pictures. Reasons for the Forum Stomper’s vigor. ~ it’s in a different pot ~ it has less soil ~ it may be possible that my dogs pissed on the other three plants. 😡 March 14, 2023 at 3:30 PM -So far every day I’ve noticed the difference in the plants. They are definitely growing and developing quickly. The forum Stomper is still outgrowing the other plants. The blood orange haze number one is growing but slower than the rest. I’ll post some more pictures and a video from yesterday and today. March 15, 2023 at 1:33 PM ~ someone left the heater, near the plants, and expose them to 90° temperatures for about 12 hours. Thank goodness the plants aren’t that big because they seem to have actually liked it. I’ll throw up a couple pictures tomorrow. The plants technically are 14 days old on the 16th. March 16, 2023 at 3:27 PM ~Today’s the last day of week one. Watering them with treated water later today.

Dia 76 desde la germinación y 48 dias después del trasplante se empieza a notar la robustez de las plantas ya miden bastante alto casi 2 M , y estan bastante ensanchadas, lo único que se puede notar la 1051 , sus ramas crecen muy rectas hacia arriba ,la white noise crece con las hojas un poco onduladas aunque no afecta a la planta. Pronto las amarraremos y ataremos con una estructura para que esten más cogidas y distribuidas las ramas y mas seguras contra viento y lluvias que empiezarán en septiembre

## Week 4 Update: Thriving Growth and New Techniques! ### 🌱 Vigorous Growth with Greenhouse Super Lemon Haze, Humboldt Seed Bubba Kush, and Blueberry Muffin 🌱 Welcome back to another exciting update on my grow journey with Greenhouse Super Lemon Haze, Humboldt Seed Bubba Kush, and Blueberry Muffin. The plants are thriving under optimal conditions, and I’ve started experimenting with new techniques to maximize their potential. --- ### Diary Snippet: Advanced Techniques and Optimal Conditions In Week 4, the plants are growing like weeds thanks to maintaining high PPFD (Photosynthetic Photon Flux Density) and optimal temperatures in the grow tent. These conditions are essential for maximizing photosynthesis and ensuring vigorous growth. --- ### Techniques Applied: LST and Defoliation #### Low-Stress Training (LST) This week, I applied Low-Stress Training (LST) for the first time. By gently bending and tying down the branches, I've created a more even canopy. This technique helps to: - **Increase Light Exposure:** Ensures all parts of the plant receive sufficient light. - **Improve Air Circulation:** Reduces the risk of mold and pests by allowing better airflow between the branches. - **Boost Yield:** Promotes the development of multiple colas, potentially increasing the overall yield. #### Defoliation In addition to LST, I also began defoliation, selectively removing some fan leaves to: - **Enhance Light Penetration:** Allows more light to reach the lower parts of the plant. - **Stimulate Growth:** Encourages the plant to focus its energy on bud development rather than foliage. --- ### Nutrient Management: Increasing Plagron Dosage As the plants grow, their nutritional needs increase. I've started to gradually increase the dosage of Plagron nutrients, following a careful schedule to prevent nutrient burn. Key benefits of Plagron nutrients include: - **Balanced Nutrient Profile:** Provides essential macro and micronutrients for robust plant growth. - **Improved Soil Structure:** Enhances the soil's ability to retain water and nutrients. - **Enhanced Flavor and Aroma:** Contributes to the development of rich, flavorful buds. --- ### Technology in Action: TM+ Pro App and TrollMaster To maintain and monitor the optimal growing conditions, I'm utilizing the TM+ Pro App and TrollMaster system: #### TM+ Pro App The TM+ Pro App has been invaluable for tracking and adjusting the environmental conditions in real-time. Key features include: - **Remote Monitoring:** Allows me to keep an eye on temperature, humidity, and light levels from anywhere. - **Data Logging:** Records environmental data for analysis, helping to fine-tune the growing conditions. - **Alerts:** Sends notifications if conditions deviate from the optimal range, enabling quick corrective actions. #### TrollMaster The TrollMaster system is integrated with the grow tent to automate and control various aspects of the environment: - **Climate Control:** Manages temperature and humidity levels to ensure a stable environment. - **Lighting Automation:** Adjusts the light intensity and schedule to mimic natural sunlight patterns. - **Nutrient Delivery:** Automates the feeding schedule, ensuring the plants receive nutrients at the right time and in the right amounts. --- ### Spotlight on Blueberry Muffin 🌿 🥦🥦🥦🥦🥦 **Cannabis Strain Benefits** 🧐 🤓 Blueberry Muffin has been a delightful addition to the grow tent. This strain is known for its sweet, berry-like aroma and potent relaxing effects. It's been growing robustly alongside the other strains and is responding well to the advanced techniques applied. - **Parentals:** Blueberry x Purple Panty Dropper - **Type:** Indica-dominant Hybrid - **Flowering Time:** 8-9 Weeks - **Flavor / Taste / Smell:** Berry, Sweet, Earthy - **Effect:** Relaxing, Euphoric, Happy - **THC Content:** 18-22% - **Characteristics:** Dense Buds, High Resin Production The Blueberry Muffin plants are showing strong growth and developing beautiful, dense buds with a rich aroma. They are a bit more sensitive to defoliation, so I've been careful to remove only the necessary leaves to ensure optimal growth without stressing the plants too much. --- ### Looking Ahead With the application of LST, defoliation, and precise nutrient management, the plants are set for an impressive growth phase. The TM+ Pro App and TrollMaster system will continue to play a crucial role in maintaining optimal conditions. Stay tuned for next week's update as the plants progress and more advanced techniques are applied! Happy growing! 🌿💚

3/03/2021 - Seeds arrived - I let one seed soak in distilled water for 12 hours. Room temperature. The other seed will go straight into a moist paper towel tomorrow. 3/04/2021 - After 12 hours of soaking I moved the seed to a moist paper towel and put in a ziploc bag. I also started another Seedsman Blueberry seed (didn’t soak it as an experiment). I put the ziploc bags in a warm dark spot. I will check it in 24 hours. 3/5/2021 - The seed I let soak for 12 hours has started to root. I’m going to let the tap root get a little bigger before I transfer it to a rock wool cube. I will check the seeds in 6 hours. Well 6 hours later the non soaked seed broke open and exposed a small tap root. Tomorrow they should be ready for rock wool cubes. 3/6/2021 - Moved the seeds to rock wool cubes. We observed that the seed that did not soak, rather just placed into moist paper towels, had the first sprout. We made sure to put root down first with spout over the top of the rock wool. 3/7/2021 - Both seeds have sprouted and are in the humidity dome. They will continue to grow until I see roots. 3/8/2021 - The sprouts look great! We will let them grow until roots appear from the bottom of the cubes. The 3rd cube in the dome is another Seedsman Blueberry we will be growing as a mother plant for clones. 3/9/2021 - Not really much to report. They seem to have stopped stretching and are taking shape nicely. I will continue to keep them in the humidity dome until they root out of the bottom. 3/10/2021 - Today all 3 seedlings had roots showing in the rock wool. I transplanted each one into solo cups filled with Fox Farm Happy Frog. I noticed the cubes were soaked and over watered. The soil will dry it out and I will start feeding them Fox Farm Big Bloom.

Still no major problems so im very happy. Theyre all continuing to fatten up and i took the first microscope shots this week and they look amazing. much more dense than any of my previous. Gorilla is behind still, guess i got a slow phenotype but its still moving along at its own pace. Starting to see amber on the others so i reckon its right at the start of the possible harvest window. I have taken off a couple of small low down popcorn buds to see how they are. I am just very impatient haha. Hopefully it continues well for the next 2 weeks!

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.
