Buenas noticias para esta semana. 1. La semana pasada comentรฉ que tenรญa una planta desordenada, pues no me habรญa percatado que la karpa tenรญa un orificio abierto en el techo y estaba entrando contaminaciรณn lumรญnica cuando dormรญa y por eso estaba dรฉbil. 2. Un loco que sabe mรกs que yo, me dijo que las puntas amarillas es algo bueno en mis plantas y no algo malo, por lo que estรกn saludables. 3. Las flores tuvieron un gran avance y ya se notan de mejor tamaรฑo y un excelente aroma. 4. El calor y la humedad hacen que cada planta consuma 2 lts de lรญquido al dรญa. 5. Voy a iniciar Pk1314 esta semana que sigue. Malas noticias 1. Ya no tengo mota seca jajaj Buenos humos

Hello everyone, Been busy but I shoot a little video for yall to see, also if growing is something you guys intended to do, I suggest you guys get yourselves a Digital Microscope or a jewlers loop. I just got myself a Digital Microscope for under $20.00 on Walmart.com, I got me a cheap one to start with so I can learn how to use it properly. But for under $20.00 this one brings 8 led lights, a adjustable mount, comes with 3 different connection choices build in, magnifies from 50-1000x, can take pictures and also videos and my favorite part, it connects right to my mobile device, you download and install a Google app and your ready to go, ill work with it and add pictures next week... See you guys soon ๐Ÿ‘Š๐Ÿ‘Š๐Ÿ‘Š

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 donโ€™t use green wavelengths, but they actually do! In fact, only around 5 โ€“ 10% of green light is reflected from leaves and the rest (90 โ€“ 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 doesnโ€™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, itโ€™s important to provide plants with a โ€œfull spectrumโ€ 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 โ€“ itโ€™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 (ฮป600โ€“700 nm) and blue (ฮป400โ€“500 nm) regions of the spectrum and not as easily in the green (ฮป500โ€“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 500โ€“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.

Hey guys :-) Unfortunately I had so much to do with the flowers that I hardly had time for the veggie update last week :-) I trained the ladies with LST and topping. I will do that for a while because you still have time until there is space in the bloom tent ๐Ÿ˜…. They were watered twice a week with 1-1.2 l each time (see table above for nutrients). Tomorrow they will be treated again with nematodes against tripse because I saw some in the vegi room ๐Ÿ˜ก. Otherwise everything was cleaned and checked.

Day 129 Flower 67 Remaining 10?!? WOW! lol they keep plumping up. most have slowed down but some of the colas are still noticeably growing. The plant on the right is quite a bit different then the other two. much shorter and has different looking colas. much more rounded. Also this plant has lots of white hairs on the main colas. Is this a sign they are still growing? how come the other 2 only have a few white hairs and this one is loaded. another distinction is that this plant hasn't really started fading yet. it has a few purple leaves but doesnt have the fade like the other 2? weird? why this plant so different. I'm quite nervous still but its all good, its just because its foreign to me. most the trichs are clear but theres a growing number of milky ones and the odd amber one. this is for the top colas i've been watching. I'm stoked to see the harvest. theres 24 yo yos in there holding up these massive colas! The flush should be any day now. I'm still confused as to know when i'm a week out and to start the flush?!? I understand harvest is when mostly milky with a few clear and amber. I cant believe the crystals on these ladies. its absolutely insane! also sticky as all hell, amazing! I'm very excited, the big day is coming up very quick Thanks again for following along and helping to make this grow what it is, let finish strong! ๐Ÿ‘Œ๐Ÿ‘Š๐Ÿ‘Š

Took a while for these plants to get to size .. I had like 20 plants in a 4x4 closet so I had to keep all these in a shot glass for literally 3 weeks they were dying for a bigger pot!

Moved the grow to the basement which caused my plants to have to readjust to the new environmental norm. It's quite a bit colder down there so I used a flood light to bring up the heat outside of the tent and had a few days of 24 hour light cycle to warm up the tent's interior environment. Once the air and reservoir warmed up enough, the plants started happily eating and showing me how much they love their new home. โœŒ๏ธโค๏ธ๐Ÿก

Merry Christmas growers!!! Been a very good week, had plenty of time with the ladies. Nothing major to report other than these two LED's aren't enough for this size tent I don't think. Will definitely be upgrading for the next grow! Thursday - fed roughly 1.5L with nutrients. Friday - did nothing. Saturday - fed roughly 1.5L with nutrients. Sunday - did nothing. Monday - fed roughly 1.5L with nutrients. Tuesday - did nothing.

Into week 4 now and I'm starting to pour the coal to these girls. I did a nutrient change and increased the solution PPM to 950. At the same time I replaced the air pump for a more powerful one as the other one I had was fairly weak. Still seem healthy and they are getting very bushy. I did a little LST mid last week and they seem to be responding well to that. This is my first grow and I'm not sure if I should defoliate a little so I can expose more tops to light or if I should just let them do their thing. I will see how they go this week.

18.04. F8 Flower Day 8 โ€“ Defoliation & Lollipopping Today a full cleanup and structural adjustment was carried out. Plants were defoliated and lollipopped to remove lower growth and improve airflow and light penetration. At the same time, branches were trained further to achieve a flat and even canopy. The full 1.2 ร— 1.2 area is now nearly filled, which should allow for optimal light usage going forward. Timing feels right, as the stretch is still ongoing but structure is now set for the flowering phase. From here on, the focus will be on maintaining the canopy and monitoring development as bud formation progresses.

Ph was way too low the last 2 weeks but ignored it, since super soil. A few plants are very not happy about it So I drained the reservoire and cleaned everything out amd PhD the water to 6.8 with some sodium bicarbonate ๐Ÿคž
