Week 4 flower went fine with all three humming along nicely in living soil. Watered to saturation after applying a 1" top dressing of worm castings, compost, and Langbeinite from Down to Earth. No need for further plant training, defoliation, or pruning. Now, just sit back and let these girls finish their run.

Black Muffin Harvest Report The Black Muffin Monster really impressed me. She grew into a beautiful and strong plant with dense, resinous buds and an amazing aroma. Unfortunately, I suspect she developed a fungal infection, probably Fusarium, which forced me to remove about four side branches. Still, the rest of the plant stayed healthy and finished strong. Overall, I’m very happy with the results and excited to see how she turns out after drying and curing. It was a great experience despite the challenges.

A light spectrum in the scope of 400 to 700nm induces growth and development, and UV (100–400nm) and infrared (700–800nm) light play a role in plant morphogenesis—which is essentially the process of plants developing their physical form and external structure. Optimizing Your Knowledge in the Grow Room To maximize your yield, always aim for 40 moles, or 40,000,000 μmol, per day. Here is how much PPFD is needed per second for each phase of cannabis growth to achieve the DLI of 40 moles of light per day. Seedling phase (18hr cycle): 200–300 μmol m-2 s-1 Vegetative phase (18hr cycle): 617 μmol m-2 s-1 Flowering phase (12hr cycle): 925 μmol m-2 s-1, (1500 μmol m-2 s-1 @2000ppm co2) (ballpark) When choosing grow lights for cannabis, it is essential to check the technical specifications to determine if they are strong enough to get the job done. Of course, this doesn't mean that you have to buy the most expensive lights there are. Still, it does mean that you should research each of these specifications in relation to your cannabis plants to find a grow light that will fully serve your needs. This is especially true with PPFD, as this is arguably the most insightful value for growers—it tells you exactly how much useful light your plants are absorbing at a certain distance from the grow light. With my fixed light source, as the plant develop height through stages, it will naturaslly grow into higher μmol ranges naturally dictated by its height. Look forward to filling the tent for the next grow. Last week will see increased blues. ELONGATED HYPOCOTYL5 (HY5), a bZIP-type transcription factor, acts as a master regulator that regulates various physiological and biological processes in plants such as photomorphogenesis, root growth, flavonoid biosynthesis and accumulation, nutrient acquisition, and response to abiotic stresses. HY5 is evolutionally conserved in function among various plant species. HY5 acts as a master regulator of a light-mediated transcriptional regulatory hub that directly or indirectly controls the transcription of approximately one-third of genes at the whole genome level. The transcription, protein abundance, and activity of HY5 are tightly modulated by a variety of factors through distinct regulatory mechanisms. This review primarily summarizes recent advances in HY5-mediated molecular and physiological processes and regulatory mechanisms on HY5 in the model plant Arabidopsis as well as in crops. Plants utilize light as the predominant energy source for photosynthesis. Besides, light signal acts as an essential external factor that mediates a variety of physiological and developmental processes in plants. Plants are continuously exposed to dynamically changing light signals due to the daily and seasonal alternation in natural conditions. The various light signals are perceived by at least five classes of wavelength-specific photoreceptors including phytochromes (phyA-phyE), cryptochromes (CRY1 and CRY2), phototropin (PHOT1 and PHOT2), F-box containing flavin binding proteins (ZTL, FKF1, and (LKP2), and UV-B RESISTANCE LOCUS 8 (UVR8). These photoreceptors are biologically activated by various light signals, subsequently initiating a large scale of transcriptional reprogramming at the whole genome level. Extensive genetic and biochemical studies have established that the ELONGATED HYPOCOTYL5 (HY5), a bZIP-type transcription factor, tightly controls the light-regulated transcriptional alternation. Loss of HY5 function mutant seedlings display drastically elongated hypocotyls in various light conditions, suggesting that HY5 acts downstream of multiple photoreceptors in promoting photomorphogenesis in plants. In addition to inhibiting hypocotyl growth, HY5 regulates other various physiological and developmental processes including root growth, pigment biosynthesis and accumulation, responses to various hormonal signals, and low and high temperatures. This review summarizes the recent advances and progress in HY5-regulated cellular, physiological, and developmental processes in various plant species. We also highlighted emerging insights regarding the HY5-mediated integration of multiple developmental, external, and internal signaling inputs in the regulation of plant growth. Among the genes regulated by the circadian clock, we found that the excision repair protein XPA is controlled by the biological clock, and we, therefore, asked whether the entire nucleotide excision repair oscillates with daily periodicity. XPA transcription and protein levels are at a maximum at around 5 pm and at a minimum at around 5 am. Importantly, the entire excision repair activity shows the same pattern. This led to the prediction that mice would be more sensitive to UV light when exposed at 5 am (when repair is low), compared to 5 pm (when repair is high). We proceeded to test this prediction. We irradiated two groups of mice with UV at 5 am and 5 pm, respectively, and found that the group irradiated at 5 am exhibited a 4–5 fold higher incidence of invasive skin carcinoma than the group irradiated at 5 pm. Currently, we are investigating whether this rhythmicity of excision repair exists in humans. Molecular mechanism of the mammalian circadian clock. CLOCK and BMAL1 are transcriptional activators, which form a CLOCK-BMAL1 heterodimer that binds to the E-box sequence (CACGTG) in the promoters of Cry and Per genes to activate their transcription. CRY and PER are transcriptional repressors, and after an appropriate time delay following protein synthesis and nuclear entry, they inhibit their own transcription, thus causing the rise and fall of CRY and PER levels with circa 24-hour periodicity (core clock). The core clock proteins also act on other genes that have E-boxes in their regulatory regions. As a consequence, about 30% of all genes are clock-controlled genes (CCG) in a given tissue and hence exhibit daily rhythmicity. Among these genes, the Xpa gene, which is essential for nucleotide excision repair, is also controlled by the clock. Circadian control of excision repair and photocarcinogenesis in mice. The core circadian clock machinery controls the rhythmic expression of XPA, such that XPA RNA and protein levels are at a minimum at 5 am and at a maximum at 5 pm. The entire excision repair system, therefore, exhibits the same type of daily periodicity. As a consequence, when mice are irradiated with UVB at 5 am they develop invasive skin carcinoma at about 5-fold higher frequency compared to mice irradiated at 5 pm when repair is at its maximum. The mouse in the picture belongs to the 5 am group with multiple invasive skin carcinomas at the conclusion of the experiment.

420Fastbuds FBT2309/Week 3 What up grow fam. Weekly update for these stunning girls. Up to this point they've been growing picture perfect . Not really doing anything special besides still feeding nutes every other watering 500ml. I'll double the feed this week taking it to 1000ml/1 liter per every other day. Not seeing any burn signs from introducing nutes so will keep that the same strength. All in all Happy Growing

Hello Growmies, Week 3 for our Watermelon Candy by Zamnesia is unfolding with promise as we observe their transition through pre-flower. Opting for low-stress training over topping, we're guiding their growth gently to maximize their potential. The plants have gracefully reached our SCROG, and with two already skillfully trained, they are demonstrating adaptability and robustness. Through the canopy, we see an even spread of foliage, indicating that our LST approach is on point. The structure of the plants is sturdy, showing that the careful maneuvering through the SCROG mesh has been well received. The greenery is lush, leaves are perked up, reaching for the light—signs that our Watermelon Candy plants are in their element and thriving. Our environmental management has mirrored the successful strategies implemented with our Epic Buzz and Red Banana Pudding strains. Daytime conditions are meticulously controlled, with the Tent-X system maintaining VPD within the ideal range for healthy plant activity. However, as we've noted with our other strains, our nighttime VPD control presents a challenge. The data indicate a discrepancy in maintaining optimal humidity levels when the lights are off, suggesting that our current setup is not fully regulating the environment during these crucial hours. The intention to integrate the Smart Mars Hydro fan into the Tent-X system is a move towards rectifying this issue, with the aim to achieve a seamless 24-hour environmental control. The transition to this enhanced system will ensure that our Watermelon Candy plants receive the same level of consistent care throughout their entire growth cycle. Their current robust state and the proactive steps we are taking to fine-tune their environment have set a strong foundation for the weeks to come. We will continue to monitor their progress closely, making adjustments where necessary, and anticipating a bountiful flowering stage ahead. Stay lifted, salokin

OCTOBER 18th to OCTOBER 24TH Sunrise: 08:31 | Sunset: 18:50 | Total Daylight: 10:19 Weather over the past week saw several consecutive days of full cloud cover and rainy periods. Greenhouse has held temperatures during the day, and only dropped below 10C once (Day 168). Good periods of sun on Day 167 and 168, with the forecast looking sunny for the next few days. I suspect that will help along the ripening process as the plants process nutrients from the fan leaves during the fade. There hasn't really been any issues with humidity levels, as it has hovered in and around 40% to 45% RH Both Lemon Orange specimens are near ripe, with many trichome heads cloudy, some clear, and few amber. Suspect it is a matter of days before they are ready to be harvested. DAY 162 2L of plain rainwater (cold) applied to all but Lemon Orange #2 (1L for this specimen). DAY 163 n/a DAY 164 15C in greenhouse in the morning; Cloudy and cool day overall, but greenhouse holding temperatures above 19C and plants are clearly going through senescence. DAY 165 Steady rain overnight, with armer temperatures; Greenhouse held overnight at 17.5C and 50% RH. Cool, cloudy and rainy day (high of 9C, 97% RH, but greenhouse and the associated equipment performing as designed and holding temperatures at 19.5C with humidity ranging from 40% to 45%. DAY 166 Cool and rainy overnight (6C intermittent light rain). Greenhouse held to 16.5C and 41% RH. Noticed some droop so provided 1L of plain rainwater (cold) via drip in the afternoon to each specimen and everyone perked up thereafter. Temperatures reached 19C for much of the day, with 43% humidity. Temperatures outdoors were a high of 7C, with 80% humidity (or more) during the day. Remained overcast for much of the day, but there was a couple of periods of increased brightness. Plants are doing well, all fading; Lemon Orange #1 is nearing full ripeness, and has displayed blue-ish purple tints in upper sugar leaves. and smells of sweet citrus. A few lower leaves are yellowing, but it hasn't progressed to fan leaves near the top of the plant. Pistils are all wilted and receded into calyxes (and have been for several days). Upon inspection, clear trichome heads outnumber cloudy ones, and there are very few if any amber ones. Lemon Orange #2 is furtherest along in senscence and is soon to drop lower leaves. Upper fan leaves are slowly fading from green to yellow. Flowers are large and comparable to Lemon Orange #1 and #2 of the Summer of 2024, have very good trichome production and smell strongly of lemon with an earthy background. Pistils have largely wilted, however those at the apex of flowers are still white. Calyxes have plumped, but they're not quite ripe yet. Upon inspection, clear trichome heads outnumber cloudy ones on calyxes, while at edge of sugar leaves there are quite a few amber heads. DAY 167 Overnight low of 2C, greenhouse held at 12.5C and 41% RH. After a cloudy cool morning, the sun broke through and warmed up the greenhouse shortly after the noon hour. Exhaust fan even came on intermittently to reduce temps below 24C. Humidity was ideal all day, in and around 40%. After noting some droop, applied 1L of plain rainwater (cold) via drip to both Lemon Orange specimens. This may be the last watering of the season. I think it will be possible to decommission the irrigation system for the winter over the coming weekend. I can pull 20L of water for use either for this crop and/or the mother tent. Lemon Orange #1 will be ready any day, but clear trichome heads still outnumber cloudy ones. Purpling of upper parts of flowers in sugar leaves and calyxes is progressing, with some yellowing of fan leaves starting to move up the plant. Flowers appear ripe with pretty much all pistils wilted and receded into their calyxes, but trichomes do not. DAY 168 Greenhouse 9.5C (-2C outside) in the morning with 40% RH. Sunny morning, with greenhouse warming to over 10C by 9:30AM; Exhaust fan kicked in to hold temperatures at 24C just before the noon hour. Both Lemon Orange specimens are showing cloudy trichomes outnumbering clear ones, and outside of the margins of sugar leaves, there are few amber trichomes present. Both plants are a mere few days away from harvest.

The double kush cake has done well in the last two weeks with almost no feeding as I realised that I overfeed her. She will continue to dry out until enough oxygen is in the substrate before I feed her again. She has ceased growing with roughly 2cm growth in the last two weeks. She is now on full bloom with little stunt on the pistols. She is filling the gaps a bit more than I anticipated and her leaves seem to be stabling out fine. She now stands approximately 58cm from the soil.

Snapped the main branch a little but its been healing ok. Besides that shes been getting bigger filling out her new pot. Also took the smaller lowest branch for my first clone attempt. Probably gonna experiment with a couple more cuttings maybe even an auto clone for laughs. Been raising the light an inch at a time as i noticed signs of light stress. All in all good week happy growing friends
