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.

Trimming started at day 11 of drying and took roughly 6 hours to complete. The final yield was 483g dried flower and 8g of dry sift from my trim bin. I pressed 6 oz into flower rosin with a yield around 25% ending up with 42g of rosin.

He's been through a beating - torrential rain & hot weather. He's strong!

Je dois déjà changer mon filtre à charbon tellement c'est fort 🤷‍♂️🤯

For the room this plant has, I'm impressed with it. I'll most likely run sour Jealousy again with more space.

swelling up nicely. pics out off the tent are from the last day off week 5. day 35 of flower

Bannandaddy auto by ethos genetics it is a brilliant plant a bit small but 10/10 buds, smell like redbull lol

3/23 12AM Monday. BKO I made from crossing Gelato 44 and Bubbles Blueberry F4 is way better than I thought LOTS of color. All are doing good, even with soft water..as long as I flush out way more than im used to. That’s an awesome success story, congratulations on pulling off that pollen chuck and getting viable seeds from your targeted branch! As a non-professional breeder working in a home setup (with the challenges of being homebound and managing everything solo), nailing a deliberate cross like this is seriously impressive. You basically created your own hybrid: **Blueberry Bubbles F4** (from Brothers Grimm Seeds, a refined take on DJ Short’s classic Blueberry lineage—sweet, creamy blueberry terps with vanilla, subtle lavender/chamomile, and those nostalgic fruity/skunky notes) pollen hitting a **Gelato 44** (the Tyson 2.0 collab with Royal Queen Seeds, which is Sunset Sherbet x Thin Mint GSC—potent, indica-dominant with citrus-cookie-earth-mint flavors, high THC around 22%, and dense, resinous buds). The result you got—those **bright red calyxes** (the small, teardrop-shaped protective structures that hold the pistils and get super frosty with trichomes)—is a beautiful, eye-catching phenotype expression. It’s not something you see every day, and it turned out “really nice” as you said. ### Why the Bright Red Calyxes? In cannabis, calyx color can shift dramatically due to genetics, environment, or stress (which you mentioned applying some to the donor plant—classic for triggering unique traits in breeding). Common causes for vivid red/purple/reddish hues in calyxes include: - **Anthocyanin expression** — These are natural pigments (same ones that make fall leaves red) that show up more under cooler temps (especially nights in late flower), pH swings, or genetic predisposition. Some strains (like certain Blueberry lines or Gelato crosses) carry genes for purple/red coloration, and stress can “unlock” it in the calyxes specifically. - **Stress response** — The stress you put on the Blueberry Bubbles donor (to induce pollen) likely influenced the offspring, amplifying colorful traits. Red calyxes often signal a plant pushing hard on resin production (trichomes galore for protection), which is a win for potency and bag appeal. - **Hybrid vigor or recombination** — Crossing a fruity, potentially purple-leaning Blueberry line with Gelato 44 (which can show some color in its family) created a new combo where the red popped on those calyxes. It’s not a “standard” look for either parent strain (Blueberry Bubbles tends toward blue/purple hues in buds, Gelato more green with frost), so you hit a rare, standout pheno. Bright red calyxes like in your pic (frosty green leaves surrounding those vivid red pods with amber hairs and tons of trichomes) often mean: - High resin/trichome density (great for potency and extracts). - Aesthetic appeal—looks killer in photos or jars. - Potentially enhanced terps/flavors from the stress/genetic shuffle (maybe more berry/cookie depth). Since you only got seeds on that one branch (pollen rub worked selectively—smart move to contain it), that’s textbook DIY breeding: low risk, targeted results. Naming it something like “Blueberry Knockout” fits perfectly—a knockout cross with knockout looks. Even if replicating it exactly is tough (breeding is part science, part luck with phenotypes), you’ve got keeper genetics now. If you grow more out, watch for stability in those red calyxes, yield, terps, and effects—it could be a gem for your personal stash or even sharing seeds with like-minded growers. The photo is stunning—those fuzzy, frost-covered calyxes with the red popping through the green are chef’s kiss. What does the smell/aroma on this one lean toward? Blueberry dominant, or more Gelato cookie/mint coming through? And how’s the high/effects shaping up? Proud of you for making this happen in your setup—it’s a real testament to your resourcefulness. 🌿🔴 Keep crushing it! If you snap more pics of the full buds or plant, I’d love to see how it fills out.👨‍🔬 3/24 4:07 AM Montel dream widow is doing great so are the two Mike Tyson‘s and the bubbles I have a Cork Screw auto in there I kind of made a mistake. I couldn’t tell it wasn’t flowering and I moved it from one tent to the other, so that one has been flowered and bagged and back to flower. I don’t know what’s gonna happen but they’re all looking great. Wish I could figure out what I’m doing right now but having these two lights instead of one at lower wattage and getting a lot of runoff, I take them into the bathtub to water them now just to make sure that the EC is where I want it to be when I’m done. It’s a heck of a lot more work this way and I didn’t mean to have this many going so it’s still working out really good though. So I have all the trailer Park boys, Montel, iced tea, two Mike Tyson’s and the one that I made the blueberry knockout that one’s really nice. I can put this on that tumor on my neck since I can never seem to die. 3/25 1:30PM MONTEL!!!! DREAM WIDOW IS THE STAND-OUT FOR LOOKS AT THE MOMENT..... Montel's Dream Widow is looking absolutely killer in these photos. The undulating, "tarantula-like" leaf pattern emerging from the buds is one of the coolest and most distinctive traits I've seen on a cannabis plant in a while. Those long, serrated fan leaves are curling and radiating outward from the cola in a wavy, almost spidery or "hairy" fashion, giving the whole bud a wild, textured, almost alien look. The heavy frost (those dense white trichomes coating everything) combined with the way the leaves are twisting and overlapping makes it look like the flower is exploding with movement. It's hypnotic and unique—definitely not your standard dense, compact cola. Why this happens This phenotype is likely a combination of: Genetics from the Montel's Dream Widow strain (a cross involving Widow family genetics—often White Widow or Widow relatives—with strong sativa-leaning or hybrid vigor that can produce more "leafy" or "foxtail" bud structures). Some Widow lines are known for expressive, airy, or "spidery" bud formations where leaves protrude dramatically from the calyxes. Your grow environment and minimal intervention (1-gallon pot, no LST, no topping) letting the plant express its natural structure. Many indica-dominant or hybrid strains tighten up with training, but when left to grow freely, they can throw these dramatic, undulating leaf patterns—especially if there's a bit of stress or environmental fluctuation that encourages the plant to "reach" with its leaves for light/air. The heavy trichome coverage suggests excellent resin production, which often pairs with these more open, leafy expressions (the plant is protecting the developing seeds/flowers with extra "armor"). Even in that small 1-gallon pot, she's putting out impressive colas with great structure, density in the center, and that signature "tarantula" flair on the edges. That's a testament to solid genetics and your hands-off approach paying off—some strains really shine when you just let them do their thing. 3/27 1:52pm. Ricky and Julian are GREAT!!!👍 The physical side is a real win Turning the grow work into functional exercise — bending, squatting, lifting gallon jugs of water (around 8 lbs each), working in the tub — is genuinely smart. It’s low-impact but builds practical strength, balance, core stability, and mobility, which is especially valuable if you have back issues. Many people with chronic pain or limited routines find that consistent, purposeful movement like this (without it feeling like “gym time”) helps keep things stretched and functional far better than doing nothing. The fact that it gives you a reason to move regularly, beyond just the plants themselves, adds real value. As long as you’re listening to your body (stopping when it feels off, not overdoing heavy lifts in one session), this kind of activity is sustainable and beneficial. You’re right — without the grow, that structured physical outlet might not exist, and the combination of tending the plants + staying active creates a positive feedback loop for both your garden and your well-being.👍👍👍🌿🌿🌿💪 3/28 3:57AM LiquidKool Bloom 1ml per gallon cal/mag .5 per gal. EC 1200 Maxi-Bloom Powered unlocked all the new bud sites!!! looks great!! 3/28 Tent 5. 2 TS1000's, D4 Viv. Fan, 1 cam, 3 usb fans 3/29 3:34AM I can either do one thing wrong or many things comedically wrong, wrong is funny we go with funny. 5am ALL Bros. Grimm seeds are wayyyyyyy beyond the others.HOE NUVA EVA!!!! Going to keep Ricky going re-vegging and she's a pet for life now. 3/29 2:45PM "Montel Iced Tea under the two TS 1000 lights (running at ~50-60W each) is hitting that sweet spot you’re looking for. The main cola being tall and just a couple inches from the light without burning is excellent. That low wattage combined with the drivers mounted outside the tent is the key “magic” here. Why This Setup Is Working So Well for You • Low heat + safe distance: At only 50-60W per light, the TS 1000 isn’t dumping excessive heat directly onto the canopy. The tall main cola can get close to the light for good light penetration without tip burn. • Drivers outside the tent: This is the big win. The driver is the main heat source on many lights. By keeping both drivers on top of the grow tent (outside), you’re keeping the tent much cooler and safer. Most other lights (including the FE 1500) keep the heavy driver inside, which turns small tents into ovens. • Fan + carbon filter mounted on top: You’re keeping all the motors and moving parts outside the enclosed space. This is smart for safety (easier to shut off or access if something goes wrong) and reduces heat buildup inside the tent. • Overall design: Less mass inside the tent = less risk, easier temperature control, and better airflow. The fact that it’s working so well with the Montel is encouraging you to redesign other tents this way. This matches your practical, safety-first style: low wattage for gentle, even coverage, everything heavy/hot mounted externally, and the ability to quickly access or shut off components. It’s not the “maximum wattage” approach many growers chase, but it’s clearly giving you better real-world results in your small tents.

Viele kleine Popcorn Buds. Das nächste mal bei der Sorte dann doch weniger Triebe vielleicht.

Both plants same weight just ones more built into a bat and the other is built with small strong side shoots

Thaught the yield would be bigger and the smell louder in generell.

GORILLA COOKIES 🍪 FF / FASTBUDS WEEK #12 FLOWER WEEK #4 FLOWER This has been another good week for this lady her buds are getting bigger with decent trichomes coverage! Stay Growing!! Gorilla Cookies FF / FASTBUDS

One Lsd-25 is moving fast while the other is still behind, they all started at the same time. Im thinking week 8 the lsd -25 plant should be ready for flushing. The Blackberry autos are doing good no signs of stress or lack nutrients

Just growing. Lots of wind here so I had to give extra support again.

Ok so here we are Day 1 of flower!! 😁😁 Thursday 19/08/21 7pm She has came out of her 36 hour dark period looking as healthy and happy as she went in! I've counted AT LEAST 30 Tops but if I'm honest I keep losing count there are so many!!! And she has had her first bloom feed 4L & NO RUN OFF AT ALL!!! She must be thirsty haha! I've gone in at half dose with the Bio Bloom & Top Max just to ease her into it however I went in at full dose with everything else! The C-Result claims to be a 100% organic yield booster which you only use once in you first feed at the beginning of flower but we shall see Other than that I'm going to keep an eye out for tip burn & as long as I don't see any she can go on full dose of bloom feed as well once she drys out!! CANT WAIT TO SEE HER STRETCH!!!! 😜👊

So the LST was going great until I accidently snapped the main stem. felt horrible but didn't give up and taped it back. couple of days later the leaves seems kind of dead but I saw new growth so I guess it worked!!!! other then that, stretch is now going hard.

Week #9 Gnomo Auto By Kannabia Week#9 Dec.23rd-Dec.30th Week #5 of Flower Week #9 Overall she's looking good. The soil mix I made is what has caused some of the color issues on my leaves. I've added some nitrogen supplement to her feeding to help address the issue. It's my first grow with Kannabia Genetics so I'll make the adjustment next grow as I mix my soil. That being said the plant has done excellent 👌 she full of trichomes even the fan 🍃 have trichomes on them. The buds are getting sticky, and stacking. Thank you for taking a look here's to a New Year growing the best Medicine!!!!

Last Week Folks ! Will update when dry for harvest and Total dry weight.
