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.

I put the autopot system on and put op a trellis net . Unfortunately I did not have a scrog net with small compartments , but I will put a second trellis in week 2 of flower with the smaller ones

Shes starting to pack on bud now very nicely with lots of frost on all buds

She has started to move again with no further deficiency so I will continue her draught and see if she improves more!

The stretch period is considered to be over. I did the last leaf cleaning. I won't touch it anymore. I did super croping because the branches got too long.

Tag 29: Die Watermelon Candy F1 Automatic von Zamnesia Seeds bleibt kompakt und kräftig. Durch den starken Blattwuchs werden die noch kleinen Ästchen beschattet. Diese in die richtige Position zu bringen ist ziemlich filigran. Tag 31: Die SF-Nematoden Kapseln für 6 Wochen Langzeitschutz sind gekommen. Beim Einarbeiten in den Boden muss es passiert sein, die Spitze ist gebrochen. Die Bruchstelle hat schon braune Ränder, kann also auch sein, dass ich das Biegen vor 2 Tagen übertrieben habe. Tag 33: Einer der oberen Seitentriebe hat die Aufgabe der Spitze übernommen und rennt los.

Right now I am just playing the waiting game with White Widow and Industrial Plant. Both have shown signs of maturation with their trichomes but neither one has a majority of milky trichomes yet. In hindsight, I should have waited until Industrial Plant was more mature before I started flushing her -- I've lost a few weeks that I could have been continuing to fatten her up. I added more bamboo rods and tied branches to them with some plant tape on both plants. White Widow's buds are rock hard and keep bending its branches so hopefully the extra support will help. I cut off the main cola and a side cola of Industrial Plant CBD due to bud rot that I failed to notice for roughly a week. After cutting out all of the bud rot I could find on Industrial Plant I checked over her and White Widow meticulously to make sure everything was kosher. I added a spare oscillating fan in the tent to try and improve air circulation in the room. I have had trouble with humidity and temperature shifts throughout this grow -- something I'll have to dial in as I progress. I imagine the climate shifts combined with how thick the main cola was probably contributed to the bud rot. Seedsman White Widow Auto is ready to be harvested as of Day 100. Over 2 days her trichomes really started to turn amber. I have started flushing her as of today and plan to harvest a day or two into the start of Week 15. As for Dinafem Industrial Plant Autoflowering CBD? I am thinking of just cutting my losses if her trichomes haven't gotten to at least majority-milky by the time White Widow gets chopped. She just looks mostly-dead and only wants a drink once every 7-10 days now. That and I have some new gear I really want to test out, as well as some different ideas for my second run that I've been itching to get started on.

Any advice will be greatly appreciated

She's well structured so far & I'm okay with that. We're in no rush, this isn't a rat race. I'm just letting her do her.

Ok this week is going well. Some of them are stretching more then the others and that's ok. Of the little bit of smells I got from them just buy rubbing a frosty sugar leaf the 1st "blue" plant has hints of mint, the 2nd "red" smells like generic weed and the 3rd "yellow" is kinda a mix of the both. I was thinking they wold have stretched more but guess not. Still have another week or two before the stretch is done and its starts to thicken up. Plants are showing some signs of something, have not looked into to much but the blushing of the leaves on plant #1 "blue" could be from my heavy hand at water or cooler nighttime temps that have been hitting it. This is the one that is having the most issues. Because of this I did a soil slurry test of all three pots and they all had aorund the same EC but the PH was different in each by a significant amount. it went up from plants 123 it is to high in plant 3 and kinda high in all the others as well yet looks fine, and the one with the highest PH its the biggest of them all. go figure. Could have been a bad sample. I did not want to disturb the roots to much but wanted to get a full spectrum of soil from top to bottom of pot. I brushed off the top dressing to not artificially mess up the EC results and took it from about a inch in from the edge of the pot in one location only vs multiple. #1 "Blue"........EC=0.25||PH=7.20 #2 "Red".........EC=0.32||PH=7.36 #3 "Yellow"....EC=0.27||PH=7.95 With this in mind I will contemplate the idea of lowering the PH levels of the water I give them to help offset this. from 6.5 down to aorund 6-6.2 Have not checked in on clone is a while, they have been outside hardening off for the most part. I only have clones of plant #2 "red" and #3 "yellow" the #1 "blue" clones died and IDK what one is what in the 2nd round of clones I just tossed a bunch of cutting from all of them into a jar. so their is some #1 blue in there maybe, I know its mostly one of the plants just can't recall what one. Applied some BTi to the soil in the last water to kill the gnats, thought I had some nematodes leftover but I did not so went out and got some BTi at the grow shop. Should do the trick. Big shoutout to Medic Grow for sponsoring the lighting in my tent, They have provided me with 2x Mini Sun 2's in the 240w configuration, They use the v1 growing spectrum that is a all purpose seed to harvest spectrum so their is no hassle of switching it mid grow.

6/23 Due To The Two 8 Day weeks this week will only consist of five days to get me back on track. SEE LAST WEEK FOR DETAILS. I DID ANOTHER EIGHT DAY WEEK. I'LL DO THIS WEEK AS SIX DAYS. THAT WAY IM BACK ON SCHEDULE. WATERED 6/22. WENT BACK AT NIGHTCAND WATERED ANOTHER GALLON WITH 1/3 TSP Armor Si. I mixed the solution with kelp you kelp me but I dumped it out. I've mixed silica with other nutes before but I had read something earlier about bioavailability issues and I didn't want to risk it. My plants are the healthiest I've ever grown. I'm considering transplanting the large 10th planet that I'm light depping. I also need to develop my ipm and my nute schedule. Still gonna have to keep an eye onvthe water situation. Luckily I have a buddy in my corner that's co tinualkt Bern a great help. WENT BACK OVER AROUND NOON. BEAUTIFUL OUTSIDE AND THE PLANTS WERE LOVING THIS SUN. I DEFOLIATED SOME BURNED LEAVES AND MIXED A SOLUTION IF KELP ME KELP YOU THAT I PLAN TO FEED TO THE GARDEN TODAY. IM HAPPY WITH HOW THINGS ARE GOING. WE HAVE SOME RAIN AND THINDERSTORMS COMING. I NEED TO GET MY IPM UP AND RUNNING AND THE NUTES ONLINE. I ALSO NEED TO DECIDE IF IM GOING TO TRANSPLANT THE LIGHT DEP 10th PLANET. Went back over to put the girls to bed at six and if was still 90 degrees. The water from yesterday had dissipated. The tops were dust dry. I mixed two gallons of kelp you kelp me and fed it to the garden. Afterwards I pointed qbd found a couple plants that were more open to the wind were a little lighter. I know tomorrow will be very hot. Maybe quarter inch of rain. However after that it will rain (showers) off and on for days. I wanted to make sure the girls had what the needed to make it through tjis heat wave until they get that rain. I had another gallon mixed up and I'm thinking I should've given it to them. Oh well. I'd rather underwater than overwater any day. I did notice a burnt top on the plant furthest from the tarp that the sun JUST BARELY TOUCHES when the rest are in shade. I'll just raise the tarp a little. These are tiny problems. Can't upload video until tomorrow. 6/24 Good thing u gave the plants that water. I know it wasn't much but we didn't get any rain. Suppised to get a qtr in today and another qtr in tomorrow. Then rain a couple more days. It's working our really good for my watering schedule lol. Yesterday the girls got there first dose of a bottled nute. They got two gallons of kelp me kelp you (1/3 tsp per gallon) and another gallon of just phed water. I was going to do another gallon but held off due to the threat of syring rain. Didn't get it bur it looks like the plants loved the kelp. It had reached 90 yesterday. They look better today. It's 70 at 9 today. I LST the 10th planet in the 3 gallon. It's getting huge. I should start a separate diary for those three light dep plants. Its cool as hell watching this. One of the purple punches is flowering pretty good. I probably should start another diary for them. I'll be starting to feed my plants soon. Wondering if I should pinch plants again. TUCKED THE LITTLE GIRLS IN AT SIX AND SHOT A VIDEO AND TOOK SOME PUCTURES. PLANTS LOOKED PHENOMINAL! GOT HOME AND AROUND SEVEN IT JUST STARTED RORREBTIAL DOWNPOURS! THE TYPE OF RAIN THAT BREAKS STEMS. I SHOULDVE PUT MY OTHET TARP UP BUT I DIDNT. I WISH I HAD. IM A LITTLE NERVOUS. I KNOW THESE GIRLS ARE STRONG THOUGH! TOMORROW. ILL ROLL THE RARP UP AND SECURE THE BOTTOM FOR FAST ACCESS. IM ALSO GOING TO KOOK INTO FINDING A TOP FOR MY CAGE I CAN USE IN INCLIMENT WEATHER. 6/25 That little qtr in of rain we were supposed to get turned into torrential downpours and high winds. Luckily no REAL damage. If you watch the video you'll see what I mean. I'm going to havecto be cognizant moving forward. Noticed a few chunks from leaves butvplants are still healthy. I'm surprised how well these girls withstood this storm. They are certainly resilient. The 2 purple punch 1 10th planet that I'm light depping are flowering nicely now. They missed all the commotion from the storm as they were inside. It's smelling good. I'm happy. 6/26 It's what a friend would say is "maineing") out. That mistcthe plants love. I'm surprised the plants are doing as good as they have been considering the wind. Will be adding nutes soon. Need to add extra supports too. Light dep 6/27 Brief periods or torrential downpours. Light depped 3 gallon 0lants are under an overhanfcwhete the hatsxrain can't hurt them but they still get sun. They are really starting to flower now! I'm going to begin feeding with a base nute and a flower nute I think. I'm thinking about giving the light dep some open sesame or something similar. I need to set up a nute program soon but the plants ALL look so healthy! And it's been raining! I've only watered like once or twice since they've been in the big pots. I've seen zero pests aside from a chunk missing from a grasshopper. Usually by now I'd have battled half a dozen things and be battling another half dozen. However I was posing from clones. These are seeds and boy don't I see the difference!

This is a regular photo seed, I'm hoping it'll be a female. If not I have some solid male genetics to cross with. 💚💜 my Blueberry strains. I have both a Blueberry & Blueberry OG in, I'm excited for both.
