La settimana passata non sono riuscito a trovare tempo per le foto. Oramai è la terza settimana di crescita . Tutte le piante crescono rigogliose e felici. Tranne una che si era spezzata mentre avevo travasato il piantino, però piano piano sta recuperando. Tenendo l umidità molto alta intorno al 70 per cento fin ora le ho annaffiate solo una volta per settimana. Praticato fimming nel 25 giorno dal seme in terra

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.

Shoguns buds are DANK & developing nicely ✌️

Replaced the dead plants...the male pollens would be collected for future breeding.

It's all about the bacteria! Took the EM1, fish shit, kefir, worm castings, soil activator, ground malted barley, fine ground egg shells (uncooked), fine ground shrimp shells (uncooked) and molasses and brewed it out as a tea for 36 hours until it was bubbling. This one I'm calling the Ultimate microbe bomb. I applied this to the ladies after I moved them to the flowering tent and boy have they exploded in Growth of just over 2" in one Gas Lantern Day. Will flop them to flower at some point in the coming days. after I get them to grow a bit taller.

4/5 First day of 12/12 light cycle. Updated solution and looking forward to the stretch. Smell is noticable and branches are getting thicker. 4/7 Had to trim some of the bigger leaves which were blocking lower branches. Switched the Bloom spectrum LEDs on and will keep the White LEDs from veg on for now. 4/9 Heat inside chamber has risen 5 degrees since I turned the bloom LEDs on.

Topped at beginning of week 3 and added co2 this week. Plants loved the co2 and top of plants are now coming back to life after a couple days. Hope they turn out nice. Hoping for a good yield but most of all quality smoke in the end

Die letzte Woche hat angefangen. In 5 Tagen werde ich sie 2 Tage Komplett im Dunkeln lassen. Ich freue mich schon auf das Ergebnis 🤤

01/26/22 PH 6.02 TDS 540 Decided to put into bud cycle. Gave 2 quarts recharge. Changed 2/3 nutrient water. Will start on foliar feeding with TPS Canopy Boost at lights out. Will foliar feed approximately every 3-4 days for the next 3 weeks. Will check PH and TDS daily. 01/27/22 PH 6.13 TDS 570 plant grew about 2 inches over night. 01/28/22 PH 6.15 TDS 630 light at 70% power 01/29/22 PH 6.1 TDS 700 tied some branches down. Gave 2 quarts recharge. Will give foliar feeding tonight at lights out. 01/30/22 PH 6.03 TDS 650 added 4 gallons water to reserve tank. Added bloom nutrients. 01/31/22 PH 6.03 TDS 705 02/01/22 PH 6.1 TDS 697

Very pleased with the SCHWAZZE 💚 Showing new growth and looking very happy! 💚💚💚💚

Day 29 - Things going along nicely .... i trimmed down some of the bigger bottom leaves, i didn't have enough soil to fill the pots, and the plants are short, bushy, weird little things, that filled out the inside of the pots..... they are only 15cm tall, but the leaves are 10+ cm .... really weird little plants.... haha.... i decided to trim the fk out of one of the ones in the double pot, and practiced topping on her.... i'll cut her down maybe trimmer her of the pot, and focus on just the 2........ they seem to be still growing upwards, so i'm not in a hurry to put em into flower mode......... on the main one i noticed some neut deficiencies ... so i upped the neuts.... should be ok, i put a good heavy neut and it stopped the spots etc..... i think some bug or something got in the double pot and is livin in there, but he doesn't eat much, haha....... the main stalks are as big as my thumb and under each canopy is all the branches..... it's really strange, to go in under all the growth and see it all .... they look kinda small, but the entire under canopy of leaves is all full .... i'm moving the huge sized leaves out and pulling each branch up over them as they grow..... this is 21 THC and 19 CBD, so it's all the good stuff for medicine ... the smell is getting abit noticable and i'm hoping the exhaust fan arrives from china soon.... just got positive ventilation into a carbon fil. ... and daily air out........ i think i had the led lights too low..... so i'll raise em abit more and see if i can get em to stretch .... Day 30 -- added some video's...... daylight vids... worth watchin for a laugh ...... first grow, so idk what i'm doin, ... any help/comments appreciated Day 32 -- added some pics of the late night trim and LST,... idk looks ok.... Day 34 -- added a video...

RSV11 is growing good. She had the light times switched 4 days ago to flower. She also had a solution change 2 days ago. She was defoliated some and is ready to start stretching.

Day 36 of flower

Moin moin an alle, immer noch nicht viel los gibt immer noch nur Wasser (ohne Ph Regelung) Pflanzen sehen ganz gut aus finde ich. Anfang der Woche hab ich gleich mal das netzt drauf geschmissen und über die Woche angefangen ein zu weben dabei ist mir am 14.02 leider einer der spitzen der Seiten äste abgerissen naja halb so wild wächst ja weiter..... Hab mich am 14.02 auch dazu entschieden ein wenig zu entblättern unterm netzt für etwas mehr Licht habe allen 4 Ladys exakt 6 Fächer Blätter entfernt also insgesamt sind 24 Blätter raus geflogen aus dem Zelt (ich Weiss, ich muss nicht mit zählen) habe die größten Blätter mal fotografiert und auch mit hoch geladen aus Langeweile. Hoffe euch geht es allen gut bis nächste Woche........ Cu ihr growmies

10 weeks from seed to harvest. The nutrient line I was using didn’t give me optimal growth, for this strain and my level of experience. Had some great growth and veg time, about 4 weeks, but when flower kicked in they got beastly. I would say I had two different phenos of this strain, and the one pheno that is unique, had slightly looser buds than the other two. This could be because of the LST/super cropping of the main cola. The other two had nice rock hard frosty buds and have similar smells and profile. The other one has more citrus, and was a bit lanky, more sativa in looks. Overall, easy enough to grow, no major surprises, and decent enough yield for 10 weeks. This is a strain that could have been better had I not had some issues with either lockout/deficiencies.

She's done! She took longer to ripen than her tent mates but she was an easy grow and her buds are dense, dank and stank! Flushed her for the last couple weeks then threw her in the dark for a couple days. I don't know if it made a difference, but I didn't want to waste the power. 14.3 wet ounces once she was chopped down. Stay tuned for the smoke report!

It’s been over a month of cure and I’ve been dipping into the stash frequently. Love this strain as a mid day smoker or even morning times. It produces a strong but not overpowering cerebral high allowing you to go about your day as planned, just in a better perspective. Very creative enabling and hyperfocus inducing Smells very sweet and berry like, seems strain review for a few more details
