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.

hi guys the little ones are progressing well a little tropical mirage has turned around and is taking a little longer all in all a natural selection proceeds automatically revealing to us which plants will then be taken for large pots and any seeds.

So I started LST and the girls seem to be responding well to the method. It has now been 4 weeks since the sprout and am I very excited. Might continue veg until it's eighth week and then switch to flowering.

As expected the look of the bud from Exotic Genetix never disappointed us but as always it come with low yield and small bud. Even though the bud tastes amazing and it give a pretty heavy indica effect

10/24/2022: plants are all healthy. Strawberry Gushers is definitely starting to flower and the Newberry is showing signs of preflower. My little guy Orange Bubblegum is still growing slowly and no signs of flower yet. The Orange Bubblegum still looks healthy, she just grows really slow. Not showing signs of any deficiencies, or over or under watering, so I think it may just be the plant. Since the other two plants are starting to flower, I top dressed with 1/3 cup Gnarly barley, 1/3 cup Craft Blend from BuildASoil, along with about 2 cups(didn't really measure, just scooped a few handfulls) of BuildAFlower. Also added a handful of bokashi on top of that. I then lightly watered the two top dressed plants, since they both received a full watering yesterday. Still doing some light LST and minor defoliation. 10/26/2022: made avtea today using TeaCo Super tea blend. Gave about 1.75 liters to the Strawberry Gushers and Newberry, since they are both starting their stretch. Gave about 1 liter to the Orange Bubblegum, since it is still the smallest. It seems to be about a week behind the other 2 plants even though they were all germinated and planted on the same days. Also raised the lite slightly, since the bigger plants were getting a little more ppfd than I wanted, but i also inceased the intensity of the light to about 80%. Been increasing by a few percent a day and plan to max it at 100% once the final plant starts to flower. The average ppfd is about 600, which is a DLI of about 40. 10/28/2022: watered about 1.5 liters per plant. This time I added Rootwise Bio-Phos, now that 2 out of the 3 plants are in flower. Also, top dressed the Orange Bubblegum. I snapped a branch on the Newberry when trying to super crop a few of the taller branches. Also noticed the Newberry was looking a little droopy today. Not sure if it was a water issue or if I turned up the light too much. I'll monitor to see how it looks later, now that I watered and raised the light a few more inches. Wanted to have a scrog net in by now, but I'm waiting for some 4 way PVC connectors so I can finish building a frame. Always just tied to the tent poles previous grows, but I wanted to try something new. 10/30/2022: watered 2 liters for the Strawberry Gushers and Newberry and 1.5 liters for the Orange Bubblegum. Added BuildASoil Coconut Powder, along with the Rootwise Bio-Phos and ThermX-70. Installed the scrog net as well. It's a little high right now, but I'm hoping the plants will grow into it. I can cut the PVC pipes shorter if I need to. Avg. VPD:1.1 PPFD: 600 DLI: 40

2 feet high by 20" wide. Watering daily, little less than a liter. PH still coming in close to 7, (+/- 0.3) Never over-water, have kept soil moist since seedling, letting it dry overnight. Always mix 0,50 ml / 1 L

Unos esquejes brutales pero las condiciones del cultivo no fueron óptimas tuvimos retrasos al principio con el crecimiento problemas de nitrogeno, algo de humedad alta al principio de la floración y aun así salió el producto muy bueno, tanto de sabor como de cómo con. Sencillez es fácil de cultivar es rápida de cojones y además es resistente.

Day 77 - June 18 June 18 - 06.00AM One Amber trichome found. Will water with 5L of water at 6.3PH this morning. Wilted leaves are still springy. I'd like to defoliate but will wait until they're completely wilted. June 18 - 06.45AM Soil is still cold, a little moist. I'll water at approximately 9AM June 18 - 10.45AM Removed dead leaves to avoid pests (as sharing tent with outdoor plants at night). June 18 - 10.45AM Watered 4.5L to runoff at 6.3PH. Time taken approximately 1 hour to saturate soil. June 19 - 09.00AM Trichomes are starting to morph from clear to cloudy. Each clear head is now about 50% cloudy. There are slightly more light amber trichomes appearing. I suspect just under a week remaining. June 20 - 07.00PM Found another amber trichome on a more developed cola. With more half-clear trichomes becoming cloudy. I suspect I'll chop in 5 days or so. Leaf necrosis is developing further with some fan leaves (with trichomes) are decaying. I'd really like to see more purple by this stage, but I'll settle for a pineapple fade. June 22 - 08.20AM Temperature ate 78F at ground level. TOO HIGH! Had to turn the AC off due to partner being cold overnight. Possibly lost terpines+potency - frustrated. Trichomes still seem too clear for my liking. June 22 - 10.40AM Watered 4-5L to runoff at 6.3PH. Should have watered yesterday, though pot was still relatively heavy. Removed one dead leaf resting on budsite. June 23 - 06.00AM Removed a few dead leaves. Trichomes are still cloudy. Some milky, it's close - though little to no ambers. June 24 - 07.00PM Removed more dead leaves + 1 healthy accidentally. Trichomes are about the same. Removed all LST ties.

98 dias de vida, vamos aumentando la cantidad de terravigor y terrateina, y el producto estrella de terranabis el Terpesyn que hace que los cogollos brillen de la resina que sacan.

Some dank top to bottom super dense tricombs and the smell is so strong

week 4 began 30th January 2022 04/02/22: the plants have really sprung up and have taken well to the bud ignitor and bloom. There are various "light sites" - the widows at the front are the smallest. Trimmed some of the lower branches on all of the plants today as well - many a dead leaf. Due to the amount of plants in the space its important that all the bud sites get adequate light. Lights at 80% and around 16 inches from the plants. Humidity is a little hight but will reduce this when I install the carbon filter and out take fan as well as an intake fan next week. over all positibe
