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.

Into week 7 and all is good. All are in flower and swelling out very nicely. Ethos OG Kush is frosty and smells like a citrus grove. Barney's Purple is an absolute beast. Her stretch was impressive for an autoflower and she is almost 48in high. Her flowers are swelling nice and she has become much more fragrant in the last week. Fastbuds Zkittlez is frosty and swelling nice. She is also very fragrant, smelling like sweet candy. Seedsman Pink Kush CBD is doing well, beautiful dark purple flowers and leaves. Lights are still 18/6. No nutes. Monitoring trichomes daily looking for changes in color and clarity in preparation for harvest.

Did another topping today. Hope there will be 8 strong main branches. Also raised temperature and humidity a little and plant looks much better now. Roots still healthy and white. UPDATE: Did defoliation for big fan leaves and LST for all 8 branches.

Week 4 Still no good weather. Rain and some sun +-15 Celsius . In the end of week 5 25 Celsius good weather

Vrchni 3/4 květů jsou sklizeny. Zbytek sklidím asi za 2 týdny

Things have been great this week for this girl. She's my pride this run as far as overall looks and bud structure. Falling over at this point from the weight. Fans leaves curling up and trichomes almost there. Will be looking to wrap this one up by the end of the week.

Day 71-1/10/22 gonna flush these babies one more time!!!!

Its clear at this point that Big Lemon is root bound bc i did not transfer her into 7gal w/One Shot. So, this week she is recovering from a calcium deficiency because my (now former) hydro store completely lagged on my 5 gal of Herc. Damn you , ZenHydro!!!! Hence, lots of sacrificed and cooked leaves, but of course the buds are fine 😎.

Photos from day 78. I am having bad humidity issues in the tent. One of my plants started to get mold. I immediately harvested the plant as it was close to being done and I wanted to try to save the my gorilla cookies and my other top gun. Still can’t get under 60% humidity. A lot of white pistils everywhere still, probably another couple weeks if I don’t get any more mold.

After turbulence the plants were placed in a tent for now i only use water

Starting eighth week of flowering.

🔥 Finish

Had a pretty good weer. I have the new carbon fil by Spider farmer. Love it has a temp and hum control built in so i can really leave it undisturbed now. Had a problem with my leaves turning brown and curling. Take a look at the picture and let me know what you think or better still watch my VIDEO. This is Ghost signing out.x ✌️🏻✌️🏻

My gorilla cookies plant from fastbuds is a really sturdy plant and it grew so much so fast it’s only my 3rd auto so I’m still getting down nutrients for autos they seem to use more than photos. The plant smells really strong like skunk. The buds are starting to fatten up and get tricombs. This plant has tons of potential for someone that knows what’s their doing with autos. You could really get it to stack a bunch if you did it right

Day 14, Two of the Orange Sherbets are a little behind & the one I’m trying to pull back from nutrient burn.. So far the White Widow Autos by Seedsman have been doing the best! Day 17 two of the Orange sherbet are a little behind the rest of the plants but overall I would say everything is going good! Seems like the orange sherbet that had the nutrient burn is starting to bounce back! Day 19 They are all really starting to take off! Probably gonna do some LST tonight or tomorrow!

Hello, folks. The week went well. We are feeding at 1200 ppm and have activated CO2 supplementation 1500ppm. Day 25 - we pruned the leaves, topped the plants, tied and stretched the branches. Next week, we'll take clones and switch to 12/12. Thanks for leaving comments and likes. Special thanks to Zamnesia Seeds and Plagron.

So, this is my first grow, just starting out. After NJ passed recreational weed, I was like you know what... Went on an amazon spending spree and got some seeds from cropkingseeds and this is it! I let the seeds soak for 18hr in deer park spring water w/ 1 drop of Organic Liquid Seaweed and Kelp Fertilizer Supplement by Bloom City. At the end of soakage, it didn't look like any had cracked maybe one did not so sure. So I did up the papertowels according to the video and have to say I feel a little nervous/anxious that there is too much water/weight on the seeds and feer drownage. I'm going to keep it on there though. I check the towels a few times throughout the day and am surprised they're very moist throughout the day and next morning still somewhat damp. 24 hours in the towels I check my babies and one had cracked but the rest were still sealed up tight, unwilling to share the goodness that we all so desire, cmon babies crack that shell for papa! 11/12 looked like 1 seed popped, yay! I remoistened towels a bit but didn't wanna soak them. I also put some rapid rooters in water to soak overnight gunna throw the seeds in them in AM... I was going to do it tonight but figured I should wait see if some pop out more. 11/13 OMG upon checking seeds at 07:10 I found the papertowels like bone dry OMG WTF!!! Panic sets in but I just set up the little terrarium with 6 plugs and put the seeds in and tore some plugs off bottom of a plug to cover seedhole with. 11/14 Got a sprout! YES!! The plugs look nice and moist just going to let it go! 11/15 Woke up this mornin, saw a new sprout peeking thru and then another about to! I got ansy and took off the little top plugs and found all the sprouts were coming up! Leaving the top plug off, hopefully thats not a bad idea.
