Worst start to week dwc had ran out of water not long hourn or two but no water and decent heat they dried out and flopped at top managed to save but taking while to get back to good health Plant too close to light some stems tanned red slight increase in distance moved fan from plant getting wind burns on low leaves overall seems ok need to flatten stems

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.

Hi@ALL, today marks the end of the first flowering week. Since the two main stems grew too tall, I had to tie them down to achieve a more even surface. The stems in the middle might still manage to reach the top. I removed all leaves that were casting shadows. The lower branches of the plant naturally receive much less light than the upper ones. I tried to tie them down as much as possible so that they stretch outwards. I hope it wasn’t wrong not to cut them. All in all, it seems to be going well for her. I’ve switched my fertilization schedule to flowering. And I’ve gradually increased the light intensity from the first flower-day until today. I started at around 800 PPFD and now I’m up to approximately 1100 PPFD. Greetings 😎👌

Re-potted into ceramic pots today and, indeed, the bottom 3/4 of the soil was quite damp. The root system was larger than I expected but quite grey in color, not vibrant white. I'm going away for 10 days so I'll just leave these babies alone and hopefully they lively up themselves.

Plants took a tumble while I was at work and came home to everything laying on the ground like a robbery. I also learned that my plants wasn't burning but in fact when the tree hit the deck the 33C heat and the roof torched the leaves. The vertical growth is slowing as it only grew 4" in the week so far, next summer hopefully I will use 20 gallons and not 12. Just solid knowledge for next year as I wanted all 3 tree to hit around 6ft after the stretch and all the training. Lost a few main branches on this plant so idk how realistic 1.5lbs is at this point

BIGGER:STRONGER:FASTER #NITROHAZE #OUTDOORGANG D115 Han engordado más los cogollos, se ven resinosos-atricomados-nevados y eso que aún no entra mucho en floración. Veo que aún crece y se sigue estirando haciendo caso omiso a entrar en floración y queriendo directamente crecer aún más y estirar sus brazos(todos). Se ve que es muy buena compañera. En las noches la estoy entrado a un cuarto oscuro para que pueda cumplir sus 12 horas de oscuridad. D120 (26julio)Avanzando en su floración, intento no regar mucho porque la humedad de noche es mucha y cuesta que baje lo húmedo del sustrato. Ah entregado muchos tricomas, ah comenzado a nevar. Lento pero Seguro. D121 Me encantan esas fotos nocturnas donde se ve la nieve ❄️🌨️

9/21 No video upload so no update 9/22 Week 10 update... finally Looks good but going to add more Phos due to some red stems showing upping to 3ml/g 9/23 Reducing Bloom nuets @10% a day for a couple, down to the 80% mark now Add Soul Peak PK to mix as well as Koolbloom need to use up the Peak and we want to see if it brings anything special. Be in flush within 7-10 days on all but the sativa FF2 Vids up 9/25 Adjusted nuets slightly 9/26 Like where the plants are so leaving nuets as is 9/27 And the tricones have over ruled me they are getting ready, 80-90% white 10-20% clear so taking the nuets to our ripening doses. Up PK down Bloom nuets

2/15: Bud sites are really starting to thicken up. I think she's going to have to fat buds on her in the future. Gave a pH balanced flush today and rotated her in the tent. 2/19: Unsure if I have a light burn situation or a nutrient situation. Opted for another pH balanced rinse in lieu of nutes. Unfortunately I can't raise my light any higher. Will monitor..

Removed a few leaves from 1st and 2nd lady which where covering some branches. 36: Some brown things in the flower. Is that normal? 1st lady is just growing in the lachuza pon granulate. it has ph 7.1 and i just watering her with pur water. maybe it will work but her developing seems to be behind 2nd lady. 37: Feeded 2nd lady with 1.5l water PH 5.8 and 2ml/l BioGrow and 2ml/l BioBloom, That cocktail had ec of 414ppm. the water had around ec of 180 ppm. I will try to optimize the mix of purified water and tap water. What should the proportion be between cal/mag? The tap water has a proportion of 7:1. 40: Feeded 2nd lady with 1.0l water PH 5.9 and 2ml/l BioGrow, 1 ml TopMax and 3ml/l BioBloom, That cocktail had ec of 580ppm. the water had around ec of 200 ppm. A few lower leaves look a very little bit turning into light green. At all she looks very healthy in my opinion. And they are really stinky 😂 The side branches grow fine. I counted 10 of them 😍 They reach nearly 30 cm. Main branch is over 40 cm I think. Need to buy a measurement think 😇 I think LST is good for dwarfs but I have to work on the technique a little bit in the future. 41: I can measure height now. 1st lady is only 28cm. 2nd lady is 38cm and side branches 28cm. 42: Same cocktail as week 40. 1.25 l

420Fastbuds FBT2303/Week11 Weekly update on these chunky girls. Did a defoliation this week on them taking off some of the bigger fan leafs. The flowers have swollen noticeable this week which is crazy as they were huge before. Over all seeing fading in the leafs as they get close to finishing up. Starting to see some amber in the trichs which is an exciting time. All in all Happy Growing
