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.

Como se puede ver ya han empezado la fase de floración 2 de ellas.. auto moon rock y auto fractal 2.. La Auto Fractal 1 todavía no a empezado la floración. La semana pasada la auto moon rock era la mas alta, pero esta semana ya esta la auto fractal 2 del mismo tamaño. Para estar en exterior con las pocas horas solares, tienen de 4 a 6 horas de sol al día, este mes esta siendo lluvioso y aun tienen menos horas.. Ya no las guardo, lo que llueva que lo aprovechen que el agua de lluvia tiene algo especial que a las plantas les encanta. Actualizacion semana 6 dia 49

Week 7 for Peyote Zkittlez by seedsman Her structure just gets better & better each week. She got another round of topping were up to 32 tops now😍. She also got a nice bit of defoliation done to her bottoms that weren't getting any lights at all. Canopy is as flat as it could be to distribute those growth hormones as even as possible. The bottom branch as caught up to the rest of the canopy as well which last week was struggling to do so. Shes getting fed 3L of water every 4 days or so until pot feels light in weigh. Have a new LED light coming in this week to handle the temps of the summer better. No more yellowish looking photos 😂

Que pasa familia, ya estamos de vuelta y empezamos la primera semana de floración, ya cambiamos el ciclo a 12/12 , y ya marco su sexo, es hembra. Pues seguimos controlando ph, lo bajamos un poco a 6,2 a ver si chupan mejor los nutrientes, temperatura y humedad controlados, siempre dentro de los parámetros correctos, hemos bajado un poco la distancia del foco, ahora en floración lo agradecerán. Así que esto es todo, ya veis que va bien tiene buen color y no hay problema ninguno, nos vemos la semana que viene fumetillas.

Bueno después de una semana solucionamos los problemas que tenía una de las últimas plantas aplicamos qué es lo que aplicamos microorganismos en grandes cantidades como para ayudar a la planta a asimilar el nuevo sustrato que pueda adaptarse de una mejor manera y pueda observar mejor los nutrientes y de ahí se solucionaron los problemas nutricionales que estaba presentando hicimos defoliación y poda de bajos y pasamos a flora este mismo día que estoy subiendo el video la planta se recuperó fenomenalmente estiró sacó nuevos brotes lo mismo hicieron las demás plantas comenzamos a regar de manera más frecuente la cantela y una vez por semana la maceta sin fondo y eso dio muchos mejores resultados los paneles subimos la intensidad de un 40% a un 65% y lo sucesión vamos a ir aumentando su intensidad hasta llegar al 100%.

Week 4 – Flowering (Day 22–28) 🌸🌱 At the end of Week 3 (Day 21) we carried out a deeper round of defoliation and some lollipopping. By now the stretch is coming to an end, with the plants settling close to their final height. We’ve also stopped foliar feeding, since every single plant is now covered in developing buds. To keep everything protected, we refreshed the beneficial insects, better be safe than sorry, how we say in German, sicher ist sicher. Already in this early stage of flowering, we can clearly spot differences in structure, bud formation and even the first aromas. Some phenos are showing exceptional promise — those will be the ones we’ll highlight more in the coming updates. 🔎 Pheno notes so far: ZR 43 – very nice structure, already showing early bud size. ZR 68 – robust side branching, healthy development. ZR 70 – compact flowers, stacking well. ZR 82 – tall, vigorous growth, strong flower initiation. ZR 30 - Fasciation, looks very interesting, I'm quite interested on how it ends up looking, having mutations like these in the grow room are not necessarily what one is looking for commercially speaking but for me is quite special, like a Zoap Rosé special edition! 😝 Zoap Rose phenos bring floral aromas with acrid undertones, giving them a distinctive edge already at this stage.

been such a great week, temps perfect, humidity is low enough (could be lower) but is what it is! i am going to start flush next week for my girls that are ready! I've introduced calmag at this stage too as they all needed it! maybe 1 week left on this girl, will use my mag lense to specify when ill chop her

hi, one more week, except for the lack of control in height due to the sativa phenotypes and a couple of plants that show some virosis. Everything is going well, good smell and plenty of resin. we're about halfway through the flowering cycle now! greetings.

Sin mucho olor gracias al filtro de carbono

I've cut down on grow at this point as the soil seems to have a lot. I'll feed for another week then think about Flushing. The kalimist will keep getting fed bloom and grow as its only been flowering for about 3 weeks due to taking longer to force flower.

Flushing as we speak! Chopping this plant in 2 days to get a harvest done before the competition ends! This is an amazingly fast plant! Resin production- ✅ Terps - ✅ Fast - ✅ Easy to grow - ✅ I cannot say enough about this lady! Just fed an average amount of nutrients. Vegged a little longer because of flower tent overflow, but once she flipped, she was fast and quality all the way! More details to come! ✌️🏻💚

Week 1 Day 1 - 8/12/2023 1st Water change Day! Such a special time it is when you remove the little bit of Nutes that you gave them as an appetizer and you give them their first real meal. Added 39 Gallons of Water to my system SILICA= .5mil/Gal = 19.5 = 20mil Root Drip = 1mil/Gal = 39mil Cal Mag= .25mil/Gal = 9.75 = 10mil FLoraMicro= 3.0mil/Gal = 114mil FloraGro = 2.0mil/Gal = 78mil FloraBloom = 2.0mil/Gal =78mil ORCA= .5mil/Gal = 19.5 = 20mil Week 1 Day 2 - 8/13/2023 Everything is looking good the roots are making thier way to the water and the new grow is looking nice and green. Week 1 Day 3- 8/14/2023 Everything is right on track, they are looking beautiful and in the praying postition all leaves happily lifting towards the light. Week 1 Day 4- 8/15/2023 Looking beautiful today and looked like she could use her first haircut.. gave her a TOP off. Roots are laying in the water everything is looking right on track.. Week 1 Day 5- 8/16/2023 walked in and the humidity was under 60.... ohh noooooo.. So I added 2 humidifiers to the tent and attached them to my InkBird controller which is set to 62. She had roots nicely in the water.. this grow is on!!! Week 1 Day 6- 8/17/2023 Humidity was a little low this morning, so I refilled the humidifiers. Other than that, the temp looks great, the PH looks great, the PPM looks good the plant is in the praying position and all damage from the little drowning seems to have been fixed. Happy Happy. Week 1 Day 7- 8/18/2023 Yay.. week 1 in the books, roots in the water growth has started first hair cut given and both side nodes are growing. Everything is looking good and on track.. A lot better than week one of the last grow when I had them drowning week 1. Really excited on how this grow is going to come out.

🎩🌈🍬 NO TINY PURPLE PISTILS STICKING OUT LIK MY LAST RUN OF RUNTZ I DID BUT WE GONE SEE HOW THEY TURN OUT 👀 #BUDSHOOT

Continua la seconda settimana di fioritura per questa tenda Fast Buds e direi che tutto va alla grande! Sto dando circa 600 ml di acqua ogni 3 giorni al momento, quando le foglie più basse sono cadenti e il vaso super leggero, quello è il loro momento, chissà perché si è sempre più tentati a dare più acqua del dovuto? Sempre quella paura che muoiano di sete, no! Loro muoiono affogate di solito che è peggio 😈 sempre asciugare bene il vaso prima di ogni innaffiatura! Non smetterò mai di ripeterlo, perché sono il primo che ancora rischia di sbagliare eheheh

CHERRY 🍒 COLA by FASTBUDS Week #11 Overall Week #6 Flower She's getting close to being done maybe 2 weeks max before harvest she's really been a starting plant throughout her grow!! Stay Growing!! FASTBUDS CHERRY 🍒 COLA

Happy plant, soon ready 😁 Today she took a shower 10 liters Now i will give only water, don't forget to measure the ph 6,3 i can't wait 😋😋😋
