This cycle was all along a great pleasure. The plants developed MUCH BETTER THAN EXPECTED, the result under the Q6W-Gen. 2 LED lamps from SANlight is FANTASTIC. I have NEVER harvested more from plants of the same strain under HPS and the quality of the bud (trichomes, taste aroma) is MUCH BETTER when grown under LED, my decision is definitely made, I will continue to solemnly grow with LED-lights in the future. I harvested 2250 gram of Shiva Skunk and 3009 gram of Serious Kush, that a total amount of 5259 gram. In relation to the 3000 Watts (incl. dimmed part!) power of the LED-lights thats an AMAZING 1,753 gram per Watt.

week intel: we reached the peak of flowering stage and need to cause a little more e.c stress from this week so e.c stress is twice a week i reduced the amount of Nitrogen and calcium and stopped feeding silicate in other hand i raised the amount of base nutrient and booster short story version: more K & P - less N stresses : a little E.C stress around 1.6 and 1.7 twice a week from this week feeding: i feed them 3 times this week with this order : day 1 : i feed them high with base nutrients(calcium & micros (half dose) + Bloom) about 822 ppm - 1.6 e.c to cause a little stress. day 3 : i feed them low dose of Top-Max + B-52 around 525 ppm - 1 e.c to let them recover a little but not fully recover still a little stress will caused. day 5 : i feed them high dose of Feeding Booster around 850 ppm - 1.7 e.c to cause e.c stress again guide of the week : from this week we can cause more E.C stresses. e.c stress if done correctly is one of the very few ways to increase quality in all aspects ( color , aroma , taste , bud structure , resin contents ) but if you over do it , listen carefully brother : it can reduce quality in every aspect so always look for signs and never reach the red line.

🔥🔥🔥🔥

I’ve stopped tucking over the past week to avoid snapping shoots during stretch. At this point I’m letting the plants do what they do best and focusing on environment and nutrition rather than manipulation. Once the second trellis net goes in, I’ll start assigning individual squares, spreading the canopy a bit more, and following up with a defoliation to improve airflow and light penetration. We’re currently 9 days into flower and the plants are healthy, vigorous, and drinking well. I couldn’t ask for a better run so far. I expect to see bud sites forming across all tops by the next update as stretch begins to slow and flower development kicks in.

Packing up a bit now. Colours are amazing, really deep purple nearly both black leaves and bright red calyx's. Absolutely stinks too, like a really pungent nose burning smell haha almost unpleasant, fruitiness is there and it's like a berry and liquorice maybe, it's really strange . A few Amber trichomes are forming but very few. Going to check back next week and see how far off before I start flushing.

Week 3 still maintaining

------------------------ HARVEST 1: ------------------------ Harvested this girl because she stopped eating and was drinking less water, and the weird flowers, so she was finishing, and im looking for something psycoactive, so the trichs are cloudy too... I expected less flowers, but there are some material behind leaves. The smoke is really nice flavored, and it hits you with psychoactivity. Despite the production and weird buds it is really tasty and gets you in a really nice sativa mood. The flavor would be like: An apple with Gasoline touches (i suppose its because of the Sour Diesel heritage) 15 gr. ------------------------ HARVEST 2: ------------------------ This plant was harvested in the optimal point to me, with cloudy trichs and a nice production. She really added weigth in the last weeks. The smell is really like the original Lemon, has deep citrous notes. Taste is very good, more powerful than the smell(Will complete this in a couple months when properly cured in jars). I like the psychoactivity, its a nice day smoke, and a tasty one. Overall a very good plant, i love the therpene profile (citrous/fruity), it is so refreshing when you smell the citrous flavour. 90 gr.

9/29/21 - We are marking today the first day of veg. That Mars Hydro TSW 2000 is doing a great job at 50% power. The plants all look great today! 9/30/21 - They look good. We are giving them water with no nutrients for this week so they will transplant nicely. 10/1/21 - They look great! I’ve been misting them in the morning. Soil is still wet from the transplant watering. We are waiting on fans and a scrog net. 10/2/21 - They are looking very good today. We mist them daily, sometimes twice a day. 10/3/21 - All plants look great! We stopped misting them for now. They look over watered a tad. We know it’s early but we started LST on a couple of the taller ones. 10/4/21 - Looking good! Just cruising along at 50% power, watering when dry. I know they won’t be low maintenance in a couple weeks when they are bushes. 10/5/21 - They look great! The ladies in the back are doing some LST still since they are much taller. It’s safe to say the roots are expanding and the plants overall are 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.

Welcome to week 3F of growfessor theatre, 4x4 edition. The ladies are looking happy and healthy. Do-si-dos received a heavy defoliation, there were a ton of small inner branches starved for light, so they got cut. LSD, Green Crack and Mandarin dreams all received a light defo, yellowing leaves were removed. Lighting provided by Mars-Hydro TSW2000. Thanks for stopping by, tune in next week growfessors for the next episode 👽🌳💚

First week from clone. Started at day 5. Good week. Worked on the discoloration and growth this week

Gorilla Zkittlez grows a little weak

May 9th - began today replacing the CMH lite that kicked-off during the night (new bulb is done!) MARS HYDRO to the rescue with a TS-1000 hanging above the kids now. Fine-tuning as we speak - began mixing a Tea for tonight/tomorrow’s dinner - LST to begin with a few of the plants this evening - Defoliated some of the large fan-leaf pairs and now the plant structures can be fortified and shaped - grabbed 6 clones from the Panama Reds and 2 each from Fighting Buddha and Pine Tar Kush !!! Into the LED Dome (And i’m out of cubes… profanity) - some branches get tied down tonight; let the games begin 10th, - Nutrients fed for breakfast - how to say this: things are so steady with daily progression - raised lights again to maintain 2c difference between Room temp / Top-Leaf temp. My Phlizon 4500 is almost topped out in the room, and its running at 50% power. This last blast of growth and transition within the plants, tells me this set-up is going to last Just long enough !!! Just big enough - 2 more weeks come on! - a few more clones taken last-nite; cloudwalker / black tuna / lsd / alaskan purple etc etc PurpsBerry will be last clone taken - no foliar misting on Food mornings like today; every other day is still the target here in mid-Veg 11th, - while rummaging through the crop early today, I found what is certainly a Male Panama Red plant. Action taken and trying to secure that new home. Picture 11, 12, 13 - Panama Red #2 removed - Foliar Misted the Tent at lites-out - clones treated to a Foliar Misting. Feeding them through their already developed Stomata on the leaves; when they have no roots to uptake nutrients yet. “Thanks Andrew at LegacyMarketFarm for that detail” May 14 - the one plant i took real pride in FIMming successfully, has also raised the Kilt and declared his Gonads; dammit. So, he’s gone lol. 2 males out of 38 plants… (txerri bilbo haze, the very first of many seeds produced alongside killer bud to show Male) - 2 LSD clones appear to be doing well May 15th - Foliar Misted after Lites-out

high temps in central europe!!! help! I guess I cant throw the girls into the swimming pool .. or can I? cca 1 or max 2 weeks till the harvest 🤩

Put the seeds into the soil about 1cm deep, mist sprayed. I've put them on a window sill as it's predicted frost tomorrow and the day after 😳 in the middle of May! Transferred outside to the pollytunnel after 48hrs on a windowsill. Watered with rainwater.

I figured I would not bore everyone with veg photos. EMERALD TRIANGLE SEEDS —-Sherbet Dip—- Sherbert x Amnesia Growing in a 2 gallon pot In Detroit Nutrient Company LIVING SOIL! Was Fed WATER ONLY in veg. She was flipped to flower 5 days ago. She was lolipopped Looking really nice! Going to start the bloom nutrients this next week! ✌️🏻💚🌿💨

Week one of flower 325 ppm 6.0 pH 65 F water temp. 71 F tent temp. 41 % RH Things are looking good. The girls are looking nice and healthy. The small one isn’t gonna catch up though lol. Oh well we will see what happens now.
