She grew 32cm this week! But look how bushier she is!! 😍

the last week before harvesting 😬😁 when trying to move the plants the branches were split due to the weight of the flowers 😱😆😋👏🏻 solved with bamboo sticks and insulating tape💪😋 irrigation with water alone until harvest💦💦💦 temperature 24 C ☀️ humidity 45% 💧 binaural sounds 🎼😎

Green light is radiation with wavelengths between 520 and 560 nm and it affects photosynthesis, plant height, and flowering. Plants reflect green light and this is why they appear green to our eyes. As a result, some growers think that plants don’t use green wavelengths, but they actually do! In fact, only around 5 – 10% of green light is reflected from leaves and the rest (90 – 95 %) is absorbed or transmitted to lower leaves [1]. Green wavelengths get used in photosynthesis. Chlorophyll pigments absorb small amounts of green wavelengths. Light that doesn’t get absorbed is transmitted to leaves that are shaded out from direct light. This means that leaves at the bottom of the canopy get more green light than leaves at the top. A high proportion of green wavelengths compared to other colors tells lower leaves that they are being shaded out, so they are able to react accordingly. Lower leaves may react by opening or closing their stomata or growing longer stems that help the leaves reach brighter light [1, 2, 3]. When it comes to growing cannabis, many cultivators are interested in the quality of light used for the flowering stage. In many plants, flowering is regulated by two main photoreceptors: cryptochrome and phytochrome. Both photoreceptors primarily respond to blue light but can also respond to green, although to a lesser extent. Green can accelerate the start of flowering in several species (although cannabis has yet to be tested) [1, 4, 5]. However, once flowering has begun, it’s important to provide plants with a “full spectrum” light that has high amounts of blue and red light, and moderate amounts of green, in order for photosynthesis to be optimized. Green light mediates seed germination in some species. Seeds use green wavelengths to decide whether the environment is good for germination. Shade environments are enriched in green relative to red and blue light, so a plant can tell if it is shady or sunny. A seed that senses a shaded environment may stay dormant to avoid poor growing conditions [1]. Some examples of plant species where researchers have documented this response are: ryegrass (a grass that grows in tufts) and Chondrilla (a plant related to dandelion) [1, 6]. Although green wavelengths generally tell plants NOT to germinate, there are some exceptions! Surprisingly, green wavelengths can stimulate seed germination in some species like Aeschynomene, Tephrosia, Solidago, Cyrtopodium, and Atriplex [1, 6, 7]. Of course, light is not the only factor affecting seed germination – it’s a combination of many factors, such as soil moisture, soil type, temperature, photoperiod, and light quality. When combined with red and blue light, green can really enhance plant growth [1, 8]. However, too much green light (more than 50% of the total light) can actually reduce plant growth [8]. Based on the most current research, the ideal ratio of green, red, and blue light is thought to be around 1:2:1 for green:blue:red [9]. When choosing a horticultural light, choose one that has high amounts of blue and red light and moderate amounts of green and other colors of light. Not many studies can be found about the effect of green light on cannabis growth or metabolism. However, if one reads carefully, there are clues and data available even from the very early papers. Mahlberg and Hemphill (1983) used colored filters in their study to alter the sunlight spectrum and study green light among others. They concluded that the green filter, which makes the environment green by cutting other wavelengths out, reduced the THC concentration significantly compared to the daylight control treatment. It has been demonstrated that green color can reduce secondary metabolite activity with other species as well. For example, the addition of green to a light spectrum decreases anthocyanin concentration in lettuce (Zhang and Folta 2012). If green light only reverses the biosynthesis of some secondary metabolites, then why put green light into a growth spectrum at all? Well, there are a couple of good reasons. One is that green penetrates leaf layers effectively. Conversely red and blue light is almost completely absorbed by the first leaf layer. Green travels through the first, second, and even third layers effectively (Figure 2). Lower leaf layers can utilize green light in photosynthesis and therefore produce yields as well. Even though a green light-specific photoreceptor has not yet been found, it is known that green light has effects independent from the cryptochrome but then again, also cryptochrome-dependent ones, just like blue light. It is known that green light in low light intensity conditions can enhance far red stimulating secondary metabolite production in microgreens and then again, counteracts the production of these compounds in high-intensity light conditions (Kim et al. 2004). In many cases, green light promoted physiological changes in plants that are opposite to the actions of blue light. In the study by Kim et al. blue light-induced anthocyanin accumulation was inhibited by green light. In another study it has been found that blue light promotes stomatal opening whereas green light promotes stomatal closure (Frechilla et al. 2000). Blue light inhibits the early stem elongation in the seedling stage whereas green light promotes it (Folta 2004). Also, blue light results in flowering induction, and green light inhibits it (Banerjee et al., 2007). As you can see, green light works very closely with blue light, and therefore not only the amount of these two wavelengths separately is important but also the ratio (Blue: Green) between these two in the designed spectrum. Furthermore, green light has been found to affect the elongation of petioles and upward leaf reorientation with the model plant Arabidopsis thaliana both of which are a sign of shade avoidance symptoms (Zhang et al. 2011) and also gene expression in the same plant (Dhingra et al. 2006). As mentioned before, green light produces shade avoidance symptoms which are quite intuitive if you consider the natural conditions where the plants grow. Not all the green light is reflected from the highest canopy leaves in nature but a lot of it (50-90%) has been estimated to penetrate the upper leaves at the plant level ((Terashima et al., 2009; Nishio, 2000). For the plant growing in the understory of the forest green light is a signal for the plant of being in the shade of a bigger plant. Then again, the plants growing under unobstructed sunlight can take advantage of the green photons that can more easily penetrate the upper leaves than the red and blue photons. From the photosynthetic pigments in higher plants, chlorophyll is crucial for plant growth. Dissolved chlorophyll and absorb maximally in the red (λ600–700 nm) and blue (λ400–500 nm) regions of the spectrum and not as easily in the green (λ500–600 nm) regions. Up to 80% of all green light is thought to be transmitted through the chloroplast (Terashima et al., 2009) and this allows more green photons to pass deeper into the leaf mesophyll layer than red and blue photons. When the green light is scattered in the vertical leaf profile its journey is lengthened and therefore photons have a higher chance of hitting and being absorbed by chloroplasts on their passage through the leaf to the lower leaves of the plant. Photons of PPFD (photosynthetic photon flux density) are captured by chlorophyll causing an excitation of an electron to enter a higher energy state in which the energy is immediately passed on to the neighboring chlorophyll molecule by resonance transfer or released to the electron transport chain (PSII and PSI). Despite the low extinction coefficient of chlorophyll in the green 500–600 nm region it needs to be noted that the absorbance can be significant if the pigment (chlorophyll) concentration in the leaf is high enough. The research available clearly shows that plants use green wavelengths to promote higher biomass and yield (photosynthetic activity), and that it is a crucial signal for long-term developmental and short-term dynamic acclimation (Blue:Green ratio) to the environment. It should not be dismissed but studied more because it brings more opportunities to control plant gene expression and physiology in plant production. REFERENCES Banerjee R., Schleicher E., Meier S.

noice.

Very happy with this week girls are drinking over a litre every 2 /3 days New led lights Very happy so far with performances

Hi everyone, farmers friends! We have come to the end of another arduous company ERI of all this fantastic plant

Well week 15 and 5th week of flower started yesterday, 9/12. I did a little more defoliation over the weekend, maybe cut 20 leaves altogether. Everything is still looking good. Temps are good, rh is good, airflow is definitely good. And judging by the frosty trichs that are showing I'd say everything is right on schedule. Starting to get more smell. That's about it for now. Happy growing everyone ✌️🍀✌️

taking it easy on the nutes.... once the roots Hit the water ....she's going to take off. I got a little too ambitious with the nutes.... and got some nute Burn... but she'll be okay... I flushed her ......very very light on the nutes now.... the new growth is green so she'll be alright.... (((patience young grasshopper))))

I touched one of the leafs with trichomes on it. Smells VERY citrusy/lemony/fruity. Very excited for this strain! Buds are very solid. It's a hybrid with Durban Poison X Rainmaker (Citral Skunk x Mandarin) x Gorilla Glue #4.

Week 4 for Space panda by atlasseed, End of week 4 for this cultivar, really wishing i had spare soil to put these these in 5L pots but i have to order some soon. At this point id of topped them both by now but they are getting any side branch growth. Im not in a rush with these girls because they will end up getting longer than 3months veg.

This week shows a lot of stem growth as well as the presence of some clones! Too excited about how big the girls are getting have a feeling they are going to be getting bigger at a fast rate at this point. I am still keeping them on the same nutrient and light schedule at the moment. I have a lot more pictures and videos this week because lets be honest I am still getting the hang of this thang!

COLOMBIAN JACK by KANNABIA Week #7 Overall Week #6 Veg This week she was growing great so I topped her again on her 2 side branches and took off the bottom branches to focus her energy on her main branches and tops. Stay Growing!! Kannabia.com COLOMBIAN JACK

Questa settimana ho deciso di montare una lampada di supporto a LED per poter far arrivare a tutte le piante abbastanza luce, le piante continuano a crescere e i fiori sembra che stiano maturando per bene spero di raccogliere almeno 4/5 piante entro 2/3 settimane,perché alcune sono molto indietro rispetto ad altre.

Week 5 for Peyote Zkittlez by seedsman, She's really starting to push in size, just from last weeks update she's been topped twice more at the top. I also transplanted her from 5L to 25L yesterday as she was drinking water everyday in the 5L pot so clearly time for a new home. 😎 Probably going to be keeping her indoor until some of my autos outdoors finish up in a month or so. Just going to giver her a few more days to adjust to the new pot then ill be pulling her as wide as i can side ways.

Hello. It 35 c. in the greenhouse today with 5 fans running. Stinkin hot in there. I hope the heat doesn't melt my THC crystals. It's suppose to be as warm tomorrow too. > I have not seen any powdery mildew on either Amnesia Lemon this year. >I have started my 2nd flush today. I' try for 4. But might have to cut a little earlier because>>> > AAHHH, I found a small patch of spider mites on the Amnesia Lemon. I only have a week to go so I decided to turn up the fans instead of spray. Yes they will progress, but slowly and they cant spin their webs in the wind, so it slows them down. And I don't mind smokin dried spider mites (isn't it extra protein). I'm blaming the house behind me, I looked through the fence and they have about 12 large pots growing cannabis, imagine that. >Starting to get some color on the Burmberry and the Sister Amnesia Lemon looks ready to be cut down. > I'll take some more pictures just before harvest and during and after. It took me 2 days to cut it down last year. I wet trim. I grew Dr. Green Thumb seeds Big Laughing last year. They made decent buds but they were not very strong, disappointed. Thought I'd try some stuff that did well inside and see what they did in the greenhouse. These plants were taken as clones, near the start of the year 2020. I moved them in the greenhouse when it was warm enough and did some training then. I started to flower them at the end of May. The tent worked great at forcing flowering at the brightest time of the year. Less chance of problems then trying to flush on a cold October day. I hope I helped makes it clearer in what I'm doing. Chuck.

420Fastbuds FBT2312/Week1 Week 1 update on these new sprouts. Been a week since they sprouted and so far seems good. I did switch from misting the top soil with my sprayer to feeding 500ml of water and 1/4tsp/gal strength General Hydroponics Calimagic about every other day. Started seeing some rust spots so I'll keep a close eye and make sure it doesn't get any worse. Over all Happy Growing

Everithing Grow fast, all is green, leaf are healthy Actually No problem 💪🏻 🤓 staY tuned for the new week upgrade 🤪

The girls are fill out beautifully green and healthy. Maintaining a clean and controlled environment is key for a healthy grow so I clean my grow area once a week with peroxide. Also doing some extra preventative maintenance for pest twice a week. Stay tuned and thanks for following
