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.

increasing nutrient doses, monitoring EC and pH doesn't bear fruit, I think. Training also takes its toll and the girls flourish. We will continue to feed and observe... Second half of week brings quite intensive growth. Continue with LST, because need light penetration and some leaves out with same purpose. What does next days bring? I am exciting...

These 3 are fattening up beautifully, the bud structures are perfect and they dont appear to be slowing down anytime soon. #3 atleast has a vanilla cream aroma to it that really gets my nipples hard, I havbt really smelled the other ones but they all look pretty similar. Only change this week is humidity os dropping as it gets colder here.

the 2nd week of veg. one of my plant growing weird I need to top it! and it's working very well with new 2 benches for sure. Actually I'm not a fan of topping auto flower ( cause I'm not a professional grower yet ) but it's fine to try it once, Peace! thank you

Day 72: 600W LED, 18 hours on 6 hours off the same with ventilation. Ferilization is the same. Water intake also remains the same 200ml per day. Humidity approx 35 percent. Day 74: I just checked the trichomes OMG this is quick one it is done getting amber I need to harvest after tomorrow. So she wont get water today tomorrow and Friday is harvest.

Day 43 All four ladies are now in flower mode. They are still looking healthy but the fight against aphis continues. I've tried garlic a few times but they keep coming, so now I am going to make a tomato leaf mixture. I've read garlic chases everything, but tomato leaves chase only the bad bugs. Tonight I will water with plain water with a ph of about 6.5, then give them a stronger dose of nutes for its current stage of growth this Saturday. Day 45 Did a bit more LST on Sour Diesel, Diesel and Royal Kush. They all got the full treatment today, I watered them with nutes and after a bit I sprayed neem oil to deal with the aphids. Day 48 Everything is still looking really nice. I sprayed some Bioneem Oil a little while ago and left it from there. I've been going every night picking off the bugs, but with the neem I've left it to see if they still try. Each day I do a little training to make sure the growth is guided. Day 50 We are on the last day of this week and I'm just amazed at the growth. My previous auto grows were just sad and nowhere near as good a looking as these. The neem seems to be working ok I guess, but I have only sprayed once. I want to get a solid schedule going with watering, nutrients and pest control. I was going to water twice but the grow medium holds water really well. Saturday = Nutrients Monday = Pest control Wednesday = Water

struggled a lil bit with humidity and temps but things were still okay

Great bud growth with white powdery resin showing. Starting to drink more water consistently every 2 to 3 days.

16th June More info on that day in week 8. 18th June 👉[550W @ 28C @ 58%]👈 550W seems pretty good. Safer option then 600W. I don't see the shroomy to grow bigger so I'm watching closely. When the veil gonna start to break, Im gonna cut the shroomy, leave the mycelium and repeat if needed. The plant where the shroomy is, lookin crazy good. SHOUT OUT TO T-KIEF FOR SHOUT OUTING ME AT STREAM! 3NT PRODUCTION OFFICIAL (follow them on YT motherTrufkcers!) Some pics for those who likes 19th June [HOT @ HOT AF] Fuck those who discriminate.

Dear diary, Week 4 almost done, but posting a day in advance as I will need help from the community! Something terrible has happened, and I am not sure what, so let’s jump into it. 🍀🍀🍀🍀🍀🍀🍀🍀🍀🍀 ⏰ Day 25: Away from home so the flatmate is feeding them from the premixed bucket. ⏰ Day 26: Back home! As they have doubled in size I am transplanting up from 3liter to 20liter airpots. The 75/25 coco to perlite mix was first run with 1.23ms 5.8ph calmag water followed by 1.33ms 5.8ph nutes before transplanting over. Light was about 305 so also upped it to 320-330ppfd. G.C #2 still is showing the weird marks and deformation, but she is growing quickly so having real issues figuring out if its something else than some genetic oddity. ⏰ Day 27: Feed the girls at 1.36ms and 6.0ph. Today was also the day where the mainlining begins! This was done by topping above the 3rd node, removing any growth below the 3rd and tying them down to start the manfold. Aiming for 8 or 16 tops for each plant depending on how the grow. ⏰ Day 28: Feeding at 1.36ms 5.8ph and adjusted ties. ⏰ Day 29: Checked in on them in the morning before lights off, and something is very wrong. All the older leaves show all kinds of issues like curling, brown and yellow spots, drooping etc. Might just be from the chock of mainlining and the lights being to strong so lowered them to 230ppfd. Later when lights turned on again, their state has not deteriorated during light off, so I’m fairly sure it is light related. But to be sure I also gave the girls 2 liter each of feed to make sure there are no dryspots, 1.36ms 6.0ph. ⏰ Day 30: I was away all day so they were watered by flatmate with 1.35ms 6ph. When I came home later in the night the spots and yellowing is still happening on the older leaves but much slower than before. I also checked runoff and it’s fine at 1.46ms and 6.0ph. ⏰ Day 30: Gave a feeding of 1.46ms 6.3ph in were I increased A and B nutes to 2.5ml/l from 2.0 and calmag to 1.5ml/l from 1.3. Someone suggested that it might be magnesium deficiency so that is why I changed the ratios and increased the EC a bit. Lastly I also gave a foliar spray of calmag water at like 12ml/l at 6.3ph to see if that helps so we can head into a smoother week 5!

text coming soon...

Still in the process of drying and curing I wait for the snap Branch drying and they're not there yet but I two of the branches were ready and I cut them and taste them even though not cure was smooth and delicious. I did not collect popcorns I kept everything in small pieces and put it in a pot for edibles. One of them main colas waiting 23.75 grams. After curing this it is a very enjoyable and smooth blueberry smoke with a very strong THC content plus the very big yield and a very good recovery from abuse make this plant a real champ

It’s day 33’from seed. All of the plants are really healthy. The plants have a really great root system at this point… I am currently slowly moving the light intensity up to the veg area. Now that are in a groove they are about to explode… I’m hoping I can flip the plants to flower in 1 weeks but I’m thinking I will wait to weeks and let them get a little larger. The plants are just now starting to look visually different next weeks update I will be ababoe to go into the visual differences, they are just not that extreme yet to really talk to much about.

1 glue gelato 120 cm начал цвести в 34- 35 дней 2 runtz 90 cm еще не начал цвести. вот вот расцветет 3 weedding cake 120 cm начал цвести 40-41 день 4 do si dos 130 cm начал цвести 40-41 день 5 Gorilla glue 120 cm начал цвести 40-41 день сегодня я промыл 2 мл/1 л floraClean, Gorilla glue , wedding, do si dos поели по 3 литра, glue gelato 2.5 литра, runtz меньше 2 литров, runtz мало ест и пока тормозит)))), в основном все нормально,я максимально не трогаю растения хочу посмотреть полный потенциал,я срезал лишь пару листьев и все,думаю это не проблема,

Great week. I went back to 24hrs of light to keep the environment steady, because I put a few babies in there. She stretched about 10 inches and has a lot of bud sites. Pretty satisfied with the new nutes all my ladies seem to be soaking it up.

Transplanted on day 6 from the jiffys into redcups with some biobizz Lightmix and COCO. Mixed a 1/4 teaspoon grennhouse bio grow in the down Part of the cup A Bit dynomyco With direct contact to the roots for the lil extra boost. Zake isnt the biggest drinker but everything Looking good so far.

17/MAY/21 D:10: Didn't have any time over the weekend to visit the tent so I was excited/nervous about what state my girls would be in... And wow, she has definitely sprouted up and gained some decent growth. Very happy with how she is growing in my new setup! A very faint odour of the generic weed smell as I opened up the tent door, she is already leaving a weedy smell on fingers after gently inspecting the leaves. Gave her some water and a very light feeding of Advanced Nutrients pH Perfect Sensi Grow Part A & B 18/MAY/21 D:11: All is well, I keep forgetting to take a dustpan and brush so I can clean the floor 😱 Will make a reminder for next visit. Other than that, she's looking great, Out of seedling phase, and she is slowly starting to veg nicely now 😁 20/MAY/21 D:13: She has packed on a nice amount of foliage, certainly looking so far like a typical Kush bush 😄 I am thinking about planting that Strawberry banana seed daily! 21/MAY/21 D:14: Decided to top her, I am going to leave the fan leaves over the weekend just to help with recovery & growth. I have removed all new growth that would grow into anything other than a fan leaf. I am following "Nugbuckets" mainlining technique, I have found a very useful step by step adaptation of this technique by "Nebula" ( https://www.growweedeasy.com/mainlining-nugbuckets ) A really interesting read, if you haven't I'd suggest checking it out! This is a tried and proved method, managed by many growers. So if it goes wrong, all responsibility is on myself. Thanks for stopping by! Peace
