Tag 65: Heute habe ich die Pflanze dann seit langen mal wieder aus der Box geholt, die ist komplett abgeknickt 😱 ich habe sie mit Mühe und Not wieder in die Box buxiert. Vielleicht muss ich noch nachhelfen, aber sie ist nirgends gebrochen.😇

We arrived in the third week the plants show good vigor and growth. Some cold days 17 Cº may have prevented further growth but we do not have to complain the plants demonstrate to be enjoying food and light. On the 15th the plants presented slightly wilted leaves as day 16 was the day of watering I imagined it was thirsty. But day 16 a few hours after watering the plant still had the same symptoms so I realized that the LED screen was 53 cm from the plant. I increased the distance to 65cm and the plant returned to normal both in force and I managed to correct the diagnosis. I am managing to apprehend some things finally putting into practice.

As my previous experience, I decided to use 10L pots, which is the best ratio I had last year regarding quantity/soil. First week only with plain water, no Ph regulation

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.

👇 This week: --- Watering 1l every day. Some phenos need more PPFD at canopy height approximately 800-850 (Increase slowly), VPD ~1.2 Big defoliation, stretch coming to the end Orange Creampop #2 HLVd test came negative Next week: Lollipopping, compost tea, defoliation --- Happy growing and thanks for checking out my report! I really appreciate you! 😁💪🙏

Hard buds with a lot of resin, very intense smell, sweet, fruity, as promised the plant produces a lot of resin, a lot, even in some fan leaves, I will dry them and put the result soon.

My Purple Star Killer girl looks great. I am doing a lot of LST to try to keep her spread out and not get too tall. She's drinking 5 gallons a day now and I think I'll have move that up to 10 gallons soon.

😎 The plant continues to give birth to new leaves and the trichomes grow in number and size 😏 With the window open there is no smell in the house, if I leave the windows closed a few hours you can smell the typical smell of marijuana only in the room where there is the plant.. 👋 I water the plant once every 3 days with 1 liter of water with the fertilizers described above.

Beginning of third week, changed up my set up! Ready to see how these girls react to the Nutes also I have two slow growing plants(purple lemonade autoflower) & (seedsman autoflower lemon)

At the beginning of the week🌱 Pound Cake - 25 cm🥇 LSD 25 - 15 cm (the plant is one week shorter than the others)🥈 Banana Purple Punch - 14cm🥉 ----------------------------------------------------------- NUTS: 1 day : +/- 0.2 - Mammoth p +/- 0.2 - Mico Chum 2 day : 0.2 - [email protected] Grow Soldier 0.2 - [email protected] Green Mystic 3 day - Just Water Repeat ♻️ ----------------------------------------------------------- With the room already painted, it's time for them to grow up free from additional stress! 🌱😃 This week I should start with low stress training👨🏻‍🌾

On day 1 I adjusted the reservoirs PH from 6.4 to 6.0. The tallest cola is 5.5" from the light. Lower colas are mostly 9"-10" from the light. On day 2 the reservoirs PH is 6.1. The tallest cola is 5" from the light. Lower colas are mostly 9"-10" from the light. On day 3 I adjusted the PH of the reservoir from 6.0 to 6.3. The tallest cola is 4.5" from the light. Lower colas are mostly 8"-10" from the light. I did my last major defoliation in order to bring more light and air flow deeper into the canopy. The plants are progressing as expected. No smell yet and the pistils are showing more each day. On day 4 I adjusted the PH of the reservoir from 6.4 to 6.1. My mini dehumidifier was emptied after being 3/4 full after 5 days running. My tallest cola is 4" from the light. Lower colas are mostly 8"-10" from the light. On day 5 I adjusted the PH of the reservoir from 6.0 to 6.3. My tallest cola is 3.5" from the light. Lower colas are mostly 8"to 10" from the light. The plants buds are growing in size with more pistils showing every day :) On day 6 the PH of the reservoir is 6.2. My tallest cola is 3.5" from the light. Lower colas are mostly 7"-9" from the light. It looks like the stretch has finally stopped. I experienced a Runaway with my blumat on my right side plant. I reduced the flow of that blumat by 1 carrot and will monitor the situation going forward. After adding my carbon filter to my exhaust I realized it was drawing the heat from my box causing in proper heating. I will try to reduce the air flow of the carbon filter to make it easier to keep the heat in the grow box. On day 7 the PH of the reservoir is 6.2. My tallest cola is 3.25" from the light. Lower colas are mostly 7"-9" from the light. I did one last major defoliation on day 21 of flower to improve airflow and light penetration keeping only the top leaves of each cola.

Wegetation 25 weeks

2018-04-03 Week 14 Day 1 Not much to say, there isn't much drama going on in growroom 2, the only things I do is giving them water and nutes 2 - 3 times/week and making sure that the lamp don't burn the girls. I gave them 4 liters today, and since they live in smartpots I can see when the pot gets wet when watering the girls, but you could hardly notice that. They are getting thirsty 😛 The flowers are developing very good, they look really healthy and their colors are fine. Power Plant XL nr 1 is 67 cm Power Plant XL nr 2 is 66 cm 2018-04-04 Raised the lamp to it’s highest level and turned all girls 1/4 turn, it’s really hard to get in to the ladies in the back, I need to push the girls up against the walls on each side and crawl on the floor to be able to turn them and give them water/nutes. Damn these plants, why do they have to grow and become so BIG?! 😆💪 Added a new video, enjoy my SoG 😄 ------------------------------------------------------------------------------------------------------------------------------------ Strain information Genetics for the famous Power Plant were captured by a group of Dutch growers on a trip to South Africa, back in the 90’s. They managed to breed a strain that was soon a popular choice in coffee shops of the Netherlands, most likely due to the soaring and intense Sativa high. Zambeza Seeds thought that the productiveness of Power Plant should never be forgotten and created an updated version, to bring the legend back to live. Power Plant XL yields up to 600-750g/m² in a flowering period of approximately 55 days! The efficiency and productiveness of Power Plant XL fears no comparison with many recently bred cannabis strains. Indoor heights of 80-110cm make this sativa-dominant variety relatively easy to grow, but outdoor growers need to be aware of the power that is being released under the sun. Outdoor plants can easily reach heights of 150-200cm, and yields of 500-600g per plant. The taste of Power Plant XL can be described as a delightful blend of sweet and sour flavours, with subtle hints of pine tree in the background. Smokers who appreciate a very strong and uplifting Sativa high will be more than satisfied with the effects. One will experience feelings of euphoria that are definitely intense and uplifting, typical for a South African Sativa like this. The up-high can also evolve into being more relaxed, especially when larger quantities are being consumed. Some people suspect Power Plant to be grown in large commercial operations around the world. It doesn’t really matter if these assumptions are the truth or myths, but Zambeza’s breeders are very proud to bring this highly productive legend back to live. The updated version of it, Power Plant XL, is the most efficient Dutch "bud factory" money can buy. ---------------------------------------------------------------------------------------------
