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.

Been a struggle keeping temperatures down and had a driver failure on my lights so was only running at 50% for a day. Running under a 600W Lush Pro COB LED with a heavy blurple spectrum. All in all the week progressed well; buds have started to fatten up nicely with frosting throughout. Cut nutrient strength in half but kept cycos recommended ratios. My EC meter malfunctioned so im kinda flying blind in that regard.

they seem great getting super frosty and the aroma is strong. the flowers are getting super dense seems like it's all going too work out. I love this cherry cola. I just stared the last bean of it and purple lemanade and BlackBerry I can't wait too see what they do outside

Going very well divine seeds

The week has been better than expected,,in the way of The Pinapple Express Auto bean from 420 Fastbuds popping and dropping her helmet in just 3 days,which was a great way to start,,! At the same time,,I’ve managed to hit the temperature and humidity levels that i like to grow in,,🌱🙏

Day 22 22/07/24 Monday Nothing new to report. Starting to see them beautiful fans appear that's all 😁✌️ Day 23 23/07/24 Tuesday Feed today, giving them straight all nutes Inc flowering nutes. I will update the dose as they grow and develop a bigger hunger. (Not sure what's wrong with Overdose #2, bit mutated, we'll see how she gets on 😅) Video updates 👌💚 Day 26 26/07/24 Friday De-chlorinated watering pH 6 with 5ml calmag to 5L water. Watered each with 250ml and had small run off. I will continue to feed/water with small run offs to help prevent salt build ups. Video update.

RLF ist immer noch hoch. Lüftung läuft auf 100% und 1 Luftentfeuchter Stein liegt drin. Tipps wie man es senken kann?

She is loving the 1000watt light. She is starting to stretch a little. There is 12 tops total. I put the tomatoe cage around her and her sister to help with support and training. Large internodal distances. Couple of calixs have popped up besides the pre flowers. No deficancys or issues, so far east strain to work with.

Gonna harvest one of the devils.. she is amazing looking... I love the fade on her and now she's in the dark. 2nd one is still stacking and looking FAT all over..gonna wait on her another week maybe. The smell, OUTTA THIS WORLD!!!

Week 9 Here we go with the updates We've been adding nutes twice a week @1800ppm every 4/5 days Day 70 She's been doing good Growing like a monster! Day 71 Very well Day 72 More LST Day 73 Schedule for 20/24hrs Day 74 Time to feed them again Floranova bloom plus water I have been watering her lil every day early morning and before bed just sprinkle some for extra humidity but not much just to recreate some good environmental flow. Day 75 SUPER growing and added more soil Day 76 End of week 9 Doing very well growing fast and good

Out of water for 3 days and when I arrive she looks with all her leads facing down. As soon I put her water she refused but after few hours she becomes very healthy. I had to cut few yellow leeds

Will start defoliation in 2 weeks. Want to try not to do that to soon. Started give some food to the ladies. Some like it, soms its just a bit to much. 💚Please Like This Diary and Leave a Comment!💚 Plants are growing nicely! Just some water @ pH 6.5 Red Wine was created by crossing Rozay F2 with Jet A. They are 2 very powerful aromatic Cali hybrids. This exclusive new Cali strain is a very strong and fast flowering indica-dominant strain. It has an aromatic, intoxicating and relaxing effect. That is comparable to enjoying a good glass of wine. Red Wine has an average flowering time of about 7-8 weeks when grown indoors. Outdoors it is ready fairly early, usually around the end of September. The yield is very good. Indoors she has an average yield of 450-650 gr/m². When growing outdoors, 600-800 grams can easily be achieved per plant. Red Wine has an aromatic scent that can be compared to a full red wine. Her full, purple-green buds are very compact with few leaves. This is very convenient when cutting the plants and saves a lot of time. Smoking this weed gives you a nice high with relaxing properties. The taste of Red Wine is very fruity sweet with an aroma of red grapes. Flowering time: 7 – 8 weeks Genetics: Rozay F2 x Jet A 30% Sativa, 70% Indica Plant height outside: 100 – 180 cm Outdoor harvest month: from June to October Yield indoors: 450 – 650 gr/m² Yield outdoors: 200 – 800 gr / plant THC: 25% 💸💸💸Wanna Try Red Wine from Seeds Genetics?💸💸💸 https://seedsgenetics.nl/product/red-wine-gefeminiseerd/

Our Zamnesia photoperiod plants have also started their journey into the magical flowering period, this is the first week. ---- The general environmental conditions are good, the heat has increased a bit again but for the first weeks of flowering it is not a big problem, let's remember to never exceed 27 degrees centigrade in the last 4 weeks to avoid jeopardizing the quality of the flowers. If necessary, open the growbox but never let it exceed 27-30 degrees where 30 is already a lot. The good thing is that as soon as the lights are turned off the change is already visible a bit and as autumn progresses we will also improve. The humidity is fluctuating but we try to control it with two dehumidifiers when necessary, pushing both possibly not into the growbox but directly into the room. (I dehumidify the room and the air in the growbox should also be dehumidified) - Our two Karen Kush plants had a bit of a hard time during the vegetative stage and I applied my emergency rule when a plant isn't doing very well. The plant that was having the most trouble was topped and is now about to send out 8 central tops and two lateral tops that were LSTed and have been branched out, really beautiful, great work, I told the guys at Zamensia that I was trying to come up with something and fingers crossed it seems I succeeded. A result that is obviously pleasing to the eye as well. Beautiful. This one is still in the vegetative stage in a separate small growbox. The second plant was also having a hard time, it seemed to be going into deficiency, it showed signs of over when I tried to recover so I gave it a good clean to give the plant less stuff to manage and now it seems we're going straight up well. She's flowering with the others. --- Technique chosen as I mentioned one of the two plants was left to vegetate, topping on the main central line up to 8 buds now growing. However, unlike the main lining, I left two side branches which also have some nice branching and I applied a symmetrical and pleasant LST. --- Feeding Program - The fertilizers are always Plagron and I am following the table that I generated on the site depending on the substrate chosen. Create your card and follow it, never be presumptuous my friend as I have been in the past, follow the card and look at the plants, not all need the same amount of fertilizer. We have arrived at the moment to give a good dose of ferrò in the first weeks of flowering, already of race life not sprayed but mixed with fertilizers. ---- https://plagron.com/en - Power Roots - 1ml/l - Alga Grow - 4 ml/l (Plant 1 in veg) - Alga Bloom - 4 ml/l (Plant in bloom) - Pure Zym - 1 ml/l - Sugar Royal - 1ml/l - Vita Race - 5 ml/l --- The 100% Organic pack by Plagron can be found on Zamnesia at the link: https://www.zamnesia.io /it/11457-pla gron-easy-pack-natural.html --- Dehumidifier is now running between 50% - 55 % / / Site Strain Description // Formidable genetics: These seeds contain the genes of Monster Bud Kush and White Widow.

All looks healthy and i can´t wait to see the next weeks pass 😁 . After my vent made me mad and started to hang i found a nice vid on YT about the "Fan Wars" and cause i disliked waiting, now he is in: Spider Farmer Vent , i love him ! , next one will be AC Infinity from the US , but this one is already pro quality 😎.

18 weeks from seed to harvest. Love 34 street seeds, quality genetics for a fair price. These garlic cookies showed no disease or pest issues, no mold or powdery mildew. Easy enough to grow, no surprises, no super stretch in flower, but I would recommend training or SCROG to control them. Pungent Pine is what I am callling this smell, over 800 grams wet weight. They are hanging to dry in my tent as I write this, 60 %RH and about 71 degrees of freedom units! Can’t wait to try it out 🇨🇦❤️🌱😎💨

Chemical reactions in which, a single substance splits up into two or more simpler substances are called decomposition reactions. These reactions are carried out by energy, supplied by different sources. The required energy can be supplied by heat (thermolysis), electricity (electrolysis), or light (photolysis). Let’s talk about photolysis reactions (not photosynthesis): Photolysis (also called photodissociation and photodecomposition) is a chemical reaction, in which a chemical (an inorganic or an organic) is broken down by photons and is the interaction of one or more photons with one target molecule. The photolysis reaction is not limited to the effects of visible light, but any photon with sufficient energy (higher than the dissociation energy of the targeted bond) can cause the chemical transformation of the said (inorganic or organic) bond(s) of a chemical. Since the energy of a photon is inversely proportional to the wavelength, electromagnetic waves with the energy of visible light or higher, such as ultraviolet light, X-rays, and γ -rays, can also initiate photolysis reactions. Like all other peroxides, hydrogen peroxide (H2O2) also consists of a relatively weaker O−O bond, which is susceptible to light or heat. The net equation for the reaction is: 2H2O2⟶2H2O+O2 The step-wise reaction mechanism is suggested as follows (Ref.1): H2O2+hν⟶2HO∙ HO∙+H2O2⟶HO−O∙+H2O HO−O∙+H2O2⟶2HO∙+H2O+O2 Using isotope studies it was confirmed that the O2 formed is cleanly derived from H2O2 (Ref.2). Notes: The rate increases rapidly in the presence of catalysts such as MnO2 and KI (Ref.2). The rate of decomposition is slow at room temperature, but it increases with temperature. It is believed to be due to thermal decomposition of H2O2, which seemingly accelerates the photolysis (Ref.3). References: 1.J. P. Hunt, H. Taube, “The Photochemical Decomposition of Hydrogen Peroxide. Quantum Yields, Tracer and Fractionation Effects,” J. Am. Chem. Soc. 1952, 74(23), 5999–6002 (https://doi.org/10.1021/ja01143a052). 2.A.

Interestingly, as early as 1934 Haber and Weiss (Ref. 1) proposed that HO2∙ is formed in the decomposition of hydrogen peroxide. The subsequent reaction of the transient superoxide radical anion with hydrogen peroxide has been determined to also form the hydroxyl radical (Ref. 2). The higher pH version of the last reaction is, therefore, best represented as: O2∙−+H2O2⟶2HO∙+OH−+O2 And as H++OH−=H2O, the net product formation is not altered. However, alkaline H2O2 is well known to be less stable than acidic hydrogen peroxide (Ref.3) even in absence of light exposure, which accelerates its decomposition (which can involve radical pathways) liberating oxygen!
