24/01/2024 Spread her out! Time for the show. Welcome to my "Barrel Of Laughs" look what shes grown in lol 25/01/2024 Lights on and moved the pot to the left side of the tent, then sorted out the canopy with the scrog! Fed her with extra seaweed to the mix. Unfortunately, she got burnt. I made the mistake of moving the light too close, overfeeding, and overusing 12% food-grade hydrogen peroxide. Conclusion: Well, onwards and upwards! I need to sort this out. Since I used hydrogen peroxide, flushing is a bad idea. I don't want to reactivate what's settled in the leaves and soil until it's no longer active. I removed all the badly damaged leaves, likening it to a necessary amputation, but luckily I'm at the early stages of flower. I'll keep a close eye on her. 25/01/2024 Mid-day Not looking good; the new growth is the same after the flush. 25/01/2024 Lights out! Can't believe I spoiled the grow, but she'll hopefully recover. The lights, particularly the sk600 and Cropmaster, are too intense and powerful. I'm wiring up a dimmer switch to reduce it to 420 watts. The Cropmaster will be removed until maturity as having over 1000 watts of LED in a small tent is too much. 26/01/2024 Mid-day Check Time! She's looking a lot better. Taking photos is a good calf workout and lower back exercise when shooting at 0.6x at 12m. There are positives to all the negative occurrences during the growing, raising, and breeding of these plants. Weed can inspire creativity, debate, contemplation, and intelligence. It's important to focus on the positive aspects these plants can bring. 26/01/2024 Temps are more normal now since removing the Cropmaster, which was very powerful. Sleepy time: 24-25°C; Daytime: 27-28°C. 27/01/2024 In recovery and doing well. Bright moon tonight. Mid-Day: She's now ready for the full tilt. I've slowly guided the colas out and all the branches looked similar in size, which is why she's ready to grow straight up. There will be a beautiful green screen underneath! I'll coin this technique 'The SpaceProvider' as it maximizes the canopy and undergrowth space. It took me two hours to sort this tonight, and she will straighten up properly in three days. The dimmer didn't work due to incorrect volts, but I managed to reduce the light to 10% today by tapping its relay wires. Mid-day: Looking a bit better. I sorted a few branches out to rearrange and ensure they will grow straight. There are definitely no free radicals left in this plant, and the fresh new growth is a positive sign. 24/01/2024 Preparing for upcoming growth spurt during flowering phase. 25/01/2024 Adjusted the scrog to accommodate the impending growth spurt. Allowing the plant to stretch freely. Will need to reposition a few colas as needed but expecting smooth sailing from here onward. Late-day temperature check: 27-28°C. 26/01/2024 Daytime temperature inside the tent remains in the 27-28°C range, similar to pre-Cropmaster lighting. Planning to implement the Cropmaster light closer to the bloom phase as we have a way to go. Committed to only guiding the upward growth and not interfering with the flowers. Each bud requires a leaf for optimal growth. Embracing a playful wordplay: "I will need to leave the flowers alone, just a little friendly play of words." I'm looking through the window, the window to your heart! https://www.youtube.com/watch?v=1nw_ob4IeOo 27/01/2024 That was a lot of supercropping today, my goodness! Even my thumb and index fingers are aching now, but hey, thumbs up for a job well done; I'll store that in my mental index book to reminisce about later when it's all over to click through! Peaceful mind 🧠, at least the canopy will be flat, unlike my occasionally bouncy head - Slowly walks quietly away to Mediate. It looks like it'll add an extra week to the harvest date. Instead of the 8th of February, we're looking at the 15th to 17th of February for when she'll be ready, but you just can't predict with Hazes; they seem to need like 13 weeks at times. I mean, March for harvest 😆. I'm no comedian, but everyone seems to be laughing at me now. Sometimes, we have to poke fun at ourselves; it's good for the spirit 👏 🙌 ✨" "I've got two extractor fans set up, one bringing in clean air and the other pushing it out. Yesterday I noticed that the extractor out fan was off before bed, due to the weight of the cables pulling it loose. The kettle lead must have come loose, but it's all sorted now." "I know what you might be thinking; he's going to get popcorn nugs by fussing and stressing the plant in the early stages of flowering. I did mention in the article that there might be a little risk, with a pun about nuggets. Honestly, I believe I'll still yield 1lb just because of the light and growing technique used, and the extended time in long veg." I accomplished what i stated using this DIY Budmaster GoD 9 250w for the vegetative stage and 450w for flowering, drawing only 320w wall power, achieving a yield of 11 ounces. Conversely, the SK600 draws 610 watts from the wall. If I can avoid further mistakes and ensure proper feeding during maturity, I anticipate a minimum of 18 ounces. With over 80 colas, the close proximity to the light, and abundant breathing space, I've developed a unique growing technique which I've dubbed "The Space Provider," due to its ability to ensure every corner of the tent is utilized for cola growth. As a shorter version, I've considered naming it "SpaceyPro." 🤔 Bring in the reflective mylar mat for under her! *_______________*_____________*_______________* #A Brief Article Summary of This Week's Discussions & Disasters! ______________________________________________ Title: From Defoliation Disaster to Cannabis Cultivation Wisdom: A Cannabis Grower's Saga So, there I was, thinking of performing a routine defoliation on my prized Forgotten Haze Cakes, a 100% sativa strain with a long flowering period from Terpzy Mutant genetics and feminized seeds. Little did I know that this seemingly simple task would unleash a comedy of errors, leading me to discover the vital importance of precision in organic cannabis cultivation. As I lovingly tended to my plants, I reached for some hydrogen peroxide - 12% food-grade, of course - to keep everything clean and healthy. After all, research has taught me that using hydrogen peroxide can be beneficial in preventing root diseases and promoting healthy root growth. However, in a classic case of good intentions gone haywire, my well-meaning application ended up in a rather unexpected chemical reaction. Who knew that bacteria from my hands and a bit too much light would turn my peaceful grow operation into a psychedelic mishap? As I gazed in bewilderment at the unexpected brown shading on the leaves, I couldn't help but laugh at the absurdity of the situation. It was as if my plants had suddenly developed a rebellious streak and decided to rebel against my well-intentioned care. I mean, really, who needs a science experiment when you have cannabis plants with their own flair for drama? Unraveling the aftermath of this defoliation debacle, I realized that beneath the chaos lay a valuable lesson in the art of cannabis cultivation. Precision, my friends, is the secret ingredient. It's all about applying the proper measurements and foreseeing the potential consequences before diving headfirst into the world of organic plant growing. Now, about using hydrogen peroxide on cannabis plants, it's crucial to dilute it properly. A popular recommendation is to prepare a solution of 3% hydrogen peroxide mixed with water in a 1:5 ratio for watering your plants. This provides the benefits of oxygenation at the root zone without harming the plants. Timing is also essential; it's typically recommended to administer the hydrogen peroxide solution during the watering schedule, ensuring that the roots receive adequate oxygenation for healthy growth. Following this incident, I delved deeper into my research, seeking advice from seasoned growers and multiple reputable sources. The experience instilled in me the importance of thorough investigation and informed decision-making when it comes to plant care. I learned that even the most well-intentioned actions can have surprising outcomes, but with extensive research and knowledge, one can minimize the chances of such mishaps. To complement the hydrogen peroxide, I also learned the benefits of diatomaceous earth, natural and effective pest control and soil amendment. After researching extensively, I discovered that applying a thin layer of diatomaceous earth to the soil surface helps deter pests like aphids, mites, and other unwanted visitors while promoting healthy root development. To apply diatomaceous earth, lightly dust it around the base of the plants and on the soil surface, taking care to avoid excessive buildup. As I embraced the twists and turns of this growing process, I couldn't help but ponder the amusing parallels between cannabis cultivation and life itself. We all aim and miss at times, but it's all part of the growth process - mind the pun. Just as in cultivating cannabis, it's essential to adapt, learn from our experiences, and continually strive for improvement. In the midst of all the chaos, amidst the pre-flowering stage of my beloved Forgotten Haze Cakes, I found myself inadvertently learning the intricate needs of my plants. And what a wild journey it has been! I can't help but see the humor in it all. After all, every mishap has its own little nugget of wisdom, right? Now, armed with this newfound insight, I plan to pass on this treasure trove of knowledge to fellow growers and those venturing into the enchanting world of cannabis cultivation. Precision, chemical reaction unpredictability, and the foresight to foresee potential consequences - these are the valuable gems I've gathered from this unpredictable turn of events. So, to all the aspiring cannabis cultivators out there, remember - every mishap holds a lesson. Embrace the unexpected, learn from your plants, and be ready for a surprise twist in your grow. Who knows, it might just turn your next gaffe into a hilarious story to share with your fellow cannabis enthusiasts! In the end, what started as a defoliation disaster has blossomed into a valuable experience, reminding me that even in the wildest of mishaps, there's a silver lining or, should I say, a luscious green lining? In the aftermath of the hydrogen peroxide mishap, a deeper understanding of the science behind its effects on the plants unfolded. Hydrogen peroxide, often used as a root boost and cleaner during or after feeds, should be approached cautiously in organic cultivation. When used inappropriately, it can have unintended and adverse effects on the delicate ecosystem of the cannabis garden. The chemical composition of hydrogen peroxide causes it to act as an oxidizer, releasing oxygen upon degradation. This reaction can be beneficial in certain contexts, such as in soil aeriation, but if incorrectly applied, it can result in detrimental outcomes. During the mishap, the hydrogen peroxide inadvertently reacted with micro metals in the diatomaceous earth, which was being used as animal food grade. This led to an unexpected chain reaction, causing the release of free radicals and a bleaching effect on the plants' leaves. Additionally, the application of hydrogen peroxide resulted in the burning of bacteria present on and within the leaf veins. This process, similar to the effect of light burn, contributed to the browning and twisting of the leaves. When leaves are exposed to excessive light or heat, they can become brown and subsequently twist up, exhibiting signs of distress. These combined effects not only altered the aesthetic appearance of the plants but also had a profound impact on their nutrient uptake, as I had elaborated upon earlier in the article. The intricate interplay of chemical reactions and biological processes within the cannabis garden underscores the necessity for precision and comprehensive knowledge in organic cultivation practices. It is a compelling reminder that every action, every component introduced to the garden, must be carefully considered for its potential consequences. The delicate balance of life within the ecosystem demands an astute understanding of the science behind each element employed in cultivation practices. This incident, though initially wrought with challenges, has ultimately deepened my comprehension of the nuanced relationship between the cannabis plants and their environment. It underscores the profound interconnectedness of the elements at play within the garden and serves as a testament to the resilience and adaptability of the cannabis plants.

I herd these sheep like ''Houghton heard a WHOOoo?'' . 30/01/2024 Sorted out the colas and arranged them freely as they grow naturally. One or two haven't fully healed from supercroping the other day, tied them up for support. Took off the main ties holding the stems back. Will keep a close eye on her pull on the Scrog during week 11. She's in her finally state now, ready to grow and bloom. Few of the flowers are showing signs of fresh new pistils. ''Crash & Sonic: Did a Dashing, Smashing Job Cleaning up'' Applied a fresh layer of top soil and 4 Litres of Distilled Water with Hydrogen Peroxide 1:5. Did a Spray Feed with Aloe Pro Natural Nutes 1;5. 30/01/2024 Mid-day: Spread her out more and re arranged again. I need to leave this plant alone. I will prefect this growing technique, I see a few mistakes I made on guiding her, rushed it a little. Can't wait to see the back-end of this plant though, lol. All the mistakes are my fault, not the plant's obviously, but you know how it goes in the garden. Little voice: "I'm taking stock of all the errors and looking to learn from them. I know I've made some missteps with my organic soil and feeding schedule, and it's time to address these issues before my next attempt" I think the timing of my feeding schedule and letting the soil dry out has been off, which may have led to the proliferation of bad bacteria in the soil. Additionally, I suspect that the wire I've been using may be causing the plant to react negatively, resulting in what looks like a poison-induced response on her stalks and stems. I've also noticed some open wounds from overdone supercropping on my part. Researching on Cannabis Organic Soil Making: After some research, I've found that making quality organic soil for cannabis cultivation requires a deep understanding of soil composition, nutrient cycles, and microbial activity. Using organic compost is essential to provide the right blend of nutrients and beneficial microorganisms to support the plant's growth. By making my own organic compost, I can ensure that it's free from any harmful contaminants and tailored to the specific needs of cannabis plants. Furthermore, I've learned that the soil needs to be well-aerated to ensure proper drainage and air circulation for the roots. This is important for maintaining a healthy microbial population in the soil, which facilitates nutrient uptake and overall plant health. It seems that my soil may have become compacted and lacking proper aeration, which could be contributing to the issues I've been experiencing. According to my research, the feeding schedule for cannabis plants is crucial, especially when working with organic soil. I've realized that I need to be more attentive to the timing and frequency of feeding to prevent the soil from drying out excessively, as this can disrupt the balance of beneficial microorganisms. From what I've read, trying to maintain a consistent moisture level in the soil is key to ensuring the well-being of these microorganisms, which in turn supports the health of the plants. Concerning the use of wire, I've come to understand that certain materials can have negative effects on plants. In my case, it seems that the wire I've been using may be leaching harmful substances into the soil, resulting in the plant's adverse reaction. I'll need to look for alternative methods for supporting the plants to avoid any further issues. Dealing with a Sensitive Haze Strain: I've also discovered that the Haze strain I've chosen to grow can be quite sensitive to its environment and feeding regimen. This can make it more prone to reacting negatively to any irregularities or contaminants in the soil. I've definitely underestimated the level of care and attention this strain requires, especially when it comes to feeding. This is a valuable lesson to keep in mind for my future growing endeavors. Moving Forward: Taking this step back and doing the research has shed a lot of light on the mistakes I may have made. Going forward, I plan to make necessary adjustments to my approach. Firstly, I'm going to focus on creating a high-quality organic compost to ensure that the soil is rich in beneficial microbes and free from any harmful substances. I'll pay close attention to the moisture levels and aeration of the soil, as well as refining my feeding schedule to better suit the needs of the sensitive Haze strain. In addition, I'll seek out alternatives to the wire support I've been using, to eliminate any potential sources of contamination for the plant. In conclusion, I'm encouraged by the opportunity to learn from these challenges and improve my growing techniques. As frustrating as it can be to face setbacks, I believe that overcoming them will ultimately make me a better grower. I'm looking forward to applying these insights and making the necessary changes in my approach to achieve better results in the futurE. 31/01/2024 Midnight for the plant time: I've lowered temps: 21c at night, 24C Daytime: should help will healing and recovery. I'll be checking in again next week – hopefully! See you all then! Let's go!" ___________________________________ 1. Why did the Forgotten Haze Cake weed stalk get arrested?

F15 Code Red has exploded in growth, aiming to get to 70 cm while the crescendo will do 55 or so. Either way both look super healthy and on track to a great flowering. I’m a little worried that the weeks 4-6 will be hard on the mute schedule, time will tell if they need the pk boost hard. Easiest grow of my life with best results, auto pots are going to be staying on every subsequent grow.

Nice steady rate of growth now. Went from 24/0 to 20/4 light schedule to encourage some stretch. Performed some light defoliation of bottom leaves and leaves growing to center of plant which were blocking bud sites. If I had not defoliators the plant would have been even bushier. At the start of this grow I wanted to encourage more bushy growth as opposed to height, but this plant has gotten almost too bushy. Increased water reservoir nutrients up to 380 ppm. Add trellising netting to further low stress train as plant grows. I’m excited for next week as preflowers have began to form, will probably be in full flowering mode next week. This thing is really starting to suck the water level down on a daily basis. If any of you guys have any tips, questions, or comments please leave them!

Sorry having issues uploading these pic went to week 4 somehow? But is actually week4 flowering, also brewing tea give my plants a little love. 05/09/2018 The boy's have been shaken twice a day last two days,dispersing copious amounts of pollen i mean clouds! It's forming layers in my tent, wish I could capture on video but its not picking it up😕 hoping it relates to strong offspring. 05/12/2018 Fourth week of flowering males are in overdrive! Making clouds of pollen I am gonna harvest some for later use (it can last 6months or more of stored correctly. I try and get video. Wish me luck👍🙏 05/14/2018 Harvesting pollen from the the boys. Video not greatest but you get the idea., Picture of #1 pollen and flower,will keep harvesting for a couple days, then cut off flowers and back to veg tent for more test. 06/18/2018 Coming up on sixth weeks after pollination, found two seeds popping out of the buds LAST week and I r germinated today!

This plant is thriving in its 3rd week of vegetation—it’s growing very healthy and strong!🌱 I’ve applied some Light Stress Training (LST) to ensure all parts of the plant are receiving equal light exposure, and it’s responding beautifully. Midway through the week, I noticed the first signs of flowering! This plant is transitioning into bloom faster than expected, which is really exciting. It seems eager to show what it’s capable of. Now, I’m looking forward to seeing how it handles the stretch phase—I can’t wait to watch it shoot up and develop further.😊

Day 40 of flower and I'm pretty impressed. Once again I wish I had trimmed the undergrowth more. I can see light through the canopy so it's far better than last run, but there's going to be a good amount of LARF down there. When I'm done working in the tent the trichromes are visible on my gloves like sand so I'm getting really hopeful it'll be a good washer. Enjoy the video this week and ignore my attempt at taking LIT style blueish Grey pictures haha

Chemical reactions in which, a single substance splits up into two or more simpler substances are called decomposition reactions. These reactions are carried out by energy, supplied by different sources. The required energy can be supplied by heat (thermolysis), electricity (electrolysis), or light (photolysis). Let’s talk about photolysis reactions (not photosynthesis): Photolysis (also called photodissociation and photodecomposition) is a chemical reaction, in which a chemical (an inorganic or an organic) is broken down by photons and is the interaction of one or more photons with one target molecule. The photolysis reaction is not limited to the effects of visible light, but any photon with sufficient energy (higher than the dissociation energy of the targeted bond) can cause the chemical transformation of the said (inorganic or organic) bond(s) of a chemical. Since the energy of a photon is inversely proportional to the wavelength, electromagnetic waves with the energy of visible light or higher, such as ultraviolet light, X-rays, and γ -rays, can also initiate photolysis reactions. Like all other peroxides, hydrogen peroxide (H2O2) also consists of a relatively weaker O−O bond, which is susceptible to light or heat. The net equation for the reaction is: 2H2O2⟶2H2O+O2 The step-wise reaction mechanism is suggested as follows (Ref.1): H2O2+hν⟶2HO∙ HO∙+H2O2⟶HO−O∙+H2O HO−O∙+H2O2⟶2HO∙+H2O+O2 Using isotope studies it was confirmed that the O2 formed is cleanly derived from H2O2 (Ref.2). Notes: The rate increases rapidly in the presence of catalysts such as MnO2 and KI (Ref.2). The rate of decomposition is slow at room temperature, but it increases with temperature. It is believed to be due to thermal decomposition of H2O2, which seemingly accelerates the photolysis (Ref.3). References: 1.J. P. Hunt, H. Taube, “The Photochemical Decomposition of Hydrogen Peroxide. Quantum Yields, Tracer and Fractionation Effects,” J. Am. Chem. Soc. 1952, 74(23), 5999–6002 (https://doi.org/10.1021/ja01143a052). 2.A. E. Cahill, H. Taube, “The Use of Heavy Oxygen in the Study of Reactions of Hydrogen Peroxide,” J. Am. Chem. Soc. 1952, 74(9), 2312–2318 (https://doi.org/10.1021/ja01129a042). 3.F. O. Rice, M. L. Kilpatrick, “The Photochemical Decomposition of Hydrogen Peroxide Solutions,” J. Phys. Chem. 1927, 31(10), 1507–1510 (https://doi.org/10.1021/j150280a004). Interestingly, as early as 1934 Haber and Weiss (Ref. 1) proposed that HO2∙ is formed in the decomposition of hydrogen peroxide. The subsequent reaction of the transient superoxide radical anion with hydrogen peroxide has been determined to also form the hydroxyl radical (Ref. 2). The higher pH version of the last reaction is, therefore, best represented as: O2∙−+H2O2⟶2HO∙+OH−+O2 And as H++OH−=H2O, the net product formation is not altered. However, alkaline H2O2 is well known to be less stable than acidic hydrogen peroxide (Ref.3) even in absence of light exposure, which accelerates its decomposition (which can involve radical pathways) liberating oxygen!

Considering topping one. One is significantly larger, plus I kinda just want to see how it goes. I know it will stunt the plant, but it might be useful to even them out so my lighting setup works more efficiently for both plants. Added Grow Big by FF this week, I'll add a half tsp every few days or so. Avoiding cal mag in combination since they have plenty of overlap.
