gonna run these runt bottoms for another week. Turned on the heat mat and growth has exploded. So gonna leave it and see what happens as I have not pending rush for the room to be cleared.

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.

Very good smell mix of gaz and exotic fruits,the buds are Soo compact!hope the weather will not be too humid 🙏

Plant 1: 2.40 Oz dry (chopped day 84) Plant 2: 4.85 Oz dry (chopped day 88) Happy with them so far. Will update post cure and smoke report.

Eine kurze Wochenbeschreibung findest du unter den Fotos. Die 16 Liter Töpfe sind bereits gut durchwurzelt. Was denkst du, sollte ich die beiden Shamaninnen noch einmal Umtopfen? Ich bin mir nicht sicher, ob das eine gute Idee ist zu Beginn der Vorblüte, habe aber Sorge, dass ich in ein paar Wochen Probleme bekomme mit der Wasserversorgung und dem Stickstoff. Sollte ich in einen größeren Topf umsetzen? Wenn ja wie groß? Schwarzkohlekompost habe ich noch genügend. Freue mich über Feedback und Tipps. Happy Growing!

🍊Salut les amis,🍊 En ce 11/11 nous voici au 48ème jour de floraison . Les couleurs des feuilles changent vraiment vite à ce stade 😲 Il me semble que c'est due au changement de valeur nutritive dans le sol. Après des semaines d'arrosages les nutriments que j'ai ajouté dans mon sol au début ce sont dissous petit à petit.☄️ Récolte prévue pour la semaine prochaine ! 🙌 🤲Avec les feuilles et les plus petites fleurs je prévois de faire du Ice hash avec des bubbles bags et une mini machine à laver. 🎥 Je vous partagerais ça prochainement✌️ 🍊🍊🍊🍊🍊🍊🍊🍊🍊🍊🍊🍊 🍊Intensité de la FC3000: 90% 🍊Ventilation : Extracteur mars hydro 6 pouces avec filtre à charbon puissance : 4/10 (24h/24h) + 2 ventilateurs à l'intérieur ( ON 10/24h). ils s'activent à un horaire différent. 🍊Arrosage : J'ai arrosé une dernière fois avec 1.5L d'eau et je vais laisser sécher au moins 5 jours avant la récolte. 🍊Température & humidité : NUIT : 15°C & 60% / JOUR : 23°C & 45% 🍊Mon instagram 🌱🧡 https://www.instagram.com/hou_stone420/ 🍊🍊🍊🍊🍊🍊🍊🍊🍊🍊🍊🍊

Brutal nuggets, you can see those diamonds shining, very compact, sticky, full of trichomes and a beautiful fragrance, I've enjoyed this strain so much guys, very special, I can recommend this strain if you want top quality fast!

9/22 topped them at 4th node. some of them are looking better for mainlining that others. some of them i may not mainline and others i left an extra node in case i want to keep clones around. #1 is looking happy with the topping and looks really good. #2 is the only one thats been praying and is the tallest and strongest looking all around. #5 short and such tight internodal spacing that it makes it hard to see whats all there. just looks like a bunch of small leaves until they grow out. i may not mainline this one either be cause of it being so tightly packed it may make it 9/27/24 day 20 theyre growing quite well. #1 i ended up taking the bottom nodes. i was originally goi g to use them as clones later on but decided to just let her go with her 4 nodes. #5 is so tightly packed, she has like 8 mains all in such a small space, its hard to even make sense of it all.

day 68, i know im a week ahead but whatever. She's chugging along nicely, kind of. To be honest she's looking a bit overcooked in my opinion lol, i thought the light may be too close but nope, light meters reading between 50,000-70,000 which is normal, plus the 70k is at the tip of those big colours. Super frosty, smells delicious, its mostly the 2 big colas at the back that need to hurry up, i've included photos. She's had 2 flushes now, last one was a few days ago. So hopefully she'll finish up nicely. No more nutrients, definitely looks like the leaves are starting to deplete themselves of food and may start dying soon. I'm guessing she may be done at day 75? hopefully. gotta remember shes about a week behind because of the time she was stunted. Just a quick update and a bunch of photos :) oh! and a video.

Effettuato topping, lst con clip e defogliazione degli strati più vicini all internodo (questo la settimana scorsa), e si può vedere un importante espansione delle foglie e irrobustimento degli steli. Tagli e tecniche necessarie per questo tipo di genetica e setup

Welcome to my Tropical Tangie From Dutch-Passion. This update is all pics I had for flowering phase. Sadly a lot of time was missed, (pics/videos) and such, as family stuff hit this crop, I just finished off the last of the puff this week. So, I have her taste and qualities fresh in my mind. So, stay tuned as full harvest & smoke review coming in the next day or two. Took a little over 8 weeks to flower. 60 days. Pre Flower she didn't really stretch so she'd be a ringer for a good SOG. The plant started to develop a lovely tangie smell early. I hit her with a the SE5000 and was at the edge. Picking up a lovely shape. The buds started to develop really nicely. Swollen calyexs, with fuzzy tops, dripping in shiny glistening trichomes. Was HST'ed early into the flowering phase. Knowing that HST works best after PRE flower has ended im sure id of gotten bigger buds. But what I did get was 21 grams of premium A grade HomeGrown. (More 2 come on that topic) Really happy with this girl and her strenghts. As a lot of my crop suffered from light exhaustion. Co2 was kept steady and the process of ppfd intake was really high and not enough co2 which led to the plant eating the very thing needed to push your plants, sugars, co2, light. And the ppfd was been kept up but sadly the co2 was not. But, she pushed through it the best out of the bunch. Hitting highs of 35c. Brought it down to 28 the last 10 days or so and cut the ppfd in half and dropped and extra co2. She ate all the Fungi in the pot, and was a happy lady. As you might be able to tell. I'm talking about this girl in the past tents, and that is because this girl and her whole 21grams got 1.5 months cure. I was smoking it upon curing also. Defo one of the best tangie puffs I've had in a long time. Brief flowering phase(s) reviews: Total time 90 days. 9 clones taken, but sadly I had to ditch that plan. I HST'ed this girl just as she was moving into pre flower. And was a very hardy girl. Drenched in sticky trichones she glistened under the light during late flowering period. Will defo be doing a SOG as she hardly stretched at all during pre flower probably 8cm, and there was a big swing in lights on/off 35c / 23c. Very easy girl to maintain and very hardy to harsh conditions. Thanks to Spider-Farmer for providing the light and to dutch for allowing me to try this baby. As I said. Harvest and puff review coming soon. She isn't a house stinker. So, some light air cleaning with an air filter and you'll be golden. But, don't be but off by this. As she'll be a stinker upon finishing or at least doing 4 weeks of curing. (More in the harvest update coming soon). 90 days + 48hr dark rest and 10 days drying at 19c and 70% rh. (Gen not my ideal conditions for drying but done 3 of my girls this way, and they're probably my best dried plants ever. No bush whack smell (hay smell).. some very nice bud that grinds a treat. Takes a little longer to dry but no dropping the RH, it must of been the steady conditions that made them some good owl phenos.. Thanks for your views and so on. Glad to be back after my few months absence.

This week I found fungus gnats I added sticky boards and mosquito bits. A small amount of fading on oldest leaves. I did a small defoliation of the yellow fan leaves. I added bone meal to the top layer of soil and worked it in. Water at 6.5.

3rd week of Veg Day 18 26/02 I'm very happy how they are growing so far they look healthy so lets keep it this way 😁 Today I gave them nutrients, I mixed the nutes in 8ltr bucket of water, had to be a dose of 16ml of each nutrient and gave 2 cups to each plant. Excited to see how they will go this week, all good so far. Day 21 01/03 Its been 3 days after their feeding, they are growing day by day strong and healthy :) I used LST on some of the auto's, some of them are still not ready for LST, by the end of this week they should be. For the Mimosa Evo I used Topping technique on their 3rd node. Also gave them water with PH 6.5 about 3 to 4 cups each Day 24 04/03 Another 3 days past and they are rapidly growing. Mimosa Evo has been 3 days since there topping and they are already showing signs of recovery. Today I used LST on all of the auto's. The critical kush auto that I used LST on them 3 days ago are doing very good, I also cut the fan leaf that blocks the light from the bottom stems and now they are stretching for the light 😌 I gave them their nutrients today same dose as before I haven't raised it yet, probably next feeding I will.

4/22/2024 Day 29 showing plenty pistils, still in the transition to flower stage. Training may help the plant grow bigger/ longer stems. They can be semi bushy when spread out. Switched nutes to flower bloom from Gaia green 4/26 day 33? Last half of week 5 there has been more of a stretch than there was previous to this. These plants have been mad with a bit of over water and chlorine issues and maybe cal mag 4/27 day 34 end of week 5 The plants both stretched. The one I didn’t train,I can see a visible growth of about double the height, just over this last week. For it being just a pre flower stretch/transition phase for the auto flowers, I am surprised at how many pistils are on the flower sights. The end of last week, I didn’t feel like there were enough pistils to consider it the beginning of flower, and now at the end of this week, it looks like this should be the end of week 1 flower, but they were still stretching.

1st March Mon - So it’s been 3 weeks since I planted her and coming into the 2nd week of veg. I’m happy to say she’s doing well we have now got 2 more leaves so she’s growing well. 2nd March Tue - Updated grow diaries today put out a question on her leaves so will update what I find out. Think I will start giving nutes in a few days but not too sure how to go about that? Will record what I find out, any comments appreciated!!! 3rd March Wed - Nothing new to update today just letting soul dry a little before I add nutes tomorrow. 4th March Thur - First day on nutrients!! Got some fresh ph balanced water at 6.5. Added 4 drops each of Dutch pro soil A+B and 3-4 drops of cal mag. This was added to 2 pints of water gave enough to the plant for it to be damp. Very excited to be moving on with the grow!! 5th March Fri (day 14 since sprout) Very excited to see the plant is responding well to nutrients the leaves are getting much bigger looking forward to see what she has to offer in the 3rd weed of veg. ....disaster struck when I was lowering the light it completely broke off and squashed the plant for no longer than 2 seconds. Only break I can see is on one of the lower leaves but hopefully it’ll bounce back! 6th March Sat - Very very disheartened today! :( but I can only try and see what happens! So I had to take a few hours away after the incident happened because I was ready to go hulksmash on the whole grow tent 😂 but with some advice from a lot of growers on here I’ve got a little motivation to continue! So I’ve tied the plant up with a stick and some thread I’ve very loosely tied it to the stalk so she straightens out. Gave her a little more water with some nutes so hopefully aid her. Will keep everything updated on how she grows with the incident in mind. Any advice at all would be very much appreciated! 7th March Sun - So we’re at the end of “week 2” after the incident I think my girls doing well. I’ve put soil upto her bottom leaves to give her more support as advised!! Gave her some water with nutes hope she picks back up this week. Excited to see how she transforms and grows!! Happy weekend guys!

Edit: I decided to harvest her tomorrow, i dont want any bud rot. Shes doing well, the buds are not fattening as much as i hoped for so i think she needs 2 more weeks here is the crux, next week itll rain nonstop, no sun and high humidity in this stage its safe to assume shell get bud rot. So i took a look through the microscope today cause im thinking about an early harvest. Its better than expected, 75% white 20% clear and 5% amber, almost all pistils are brown. If you have suggestions, leaving her to grow in real bad weather or an emergency harvest, what do you think would be better?

On to the dry

✌️🎃 Thank you for checking my cultivation. ☹️ The 1th seed didn’t germinate. 😃 But 2th seed looks all right.
