All plants are now dried over the space of 10 days at roughly 65f and 55% humidity in the dark. It’s been 2 weeks into the cure and the smells are popping and the sample buds taste great and get me lit af. Didn’t really expect 5 vastly different phenotypes from 5 seeds, is this the norm?

Trying flawless finish for the first time, hoping it will help with this rushed flowering stage. Really unfortunate to have to cut this one short, but some things in life are out of our control... Anyway, harvest is currently curing. Check out the results and leave a like/comment cos I'm always looking for constructive criticism! Lets gooo

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.

So much stretching going on this week. I think we are just about done though. Which is good because I do not want to have to move the exhaust and all. Really upped the nutrients this week. Burned em just a tad but I think I found her sweet spot. 1300-1500 ppm. Seems strong but if I even go down to 1000ppm #3 starts getting yellow. Finally some nice flowers forming. Aromas are starting to fill the room when I open the tent each morning. I thought this was supposed to be an 8 weeks strain but I'm 17 days in and it's feeling more like a 10-11 week strain.

Всем тем, кто следит за мной здоровья и удачи. Наступило время вновь обновить «LSD» от «Barney's Farm». Уже четвёртая неделя от прорастания семечек. Прогресс очевиден. Я планирую выращивать клонов с нижних веток, именно поэтому я сделал дефолиацию на ранней стадии и не стал формировать крону, так как нижние ветки растения будут клонированы. Дефолиация полезна не только тем, что открывает свет боковым веткам, но также огромные листьев не забирают важные гормоны роста. В этот раз не стал добавлять какие-либо удобрения, а пролил обычной водой с пониженным PH. Так же я подключил дополнительное освещенье полный спектр LED по 27W. Теперь я оставлю растение в покое и буду ждать, когда отрастут ветки на клонирование. ---------------------------------------------------------------------------------------------------------------------------------------------- All those who follow me health and good luck. It's time to update the" LSD "from" Barney's Farm " again. It is already the fourth week from the germination of seeds. Progress is obvious. The average height of plants is 13-15 centimeters, which is much lower than the other two strains, but their leaves and internodes are shorter. I plan to grow clones from the lower branches, which is why I did defoliation at an early stage and did not form a crown, since the lower branches of the plant will be cloned. Defoliation is useful not only because it opens the light to the side branches, but also because the leaves do not take away important growth hormones. This time I did not add any fertilizers, but spilled it with ordinary water with a low PH. I also connected additional lighting with a full range of 27W LED. Now I will leave the plant alone and wait for the branches to grow for cloning.

Was a difficult week, because the plant was at the very back. I got some small % of bud rot. Very small. Buds are very dense. Dripping in trichomes. Colorful, and very stinky. What a beauty.

Well I’m pretty excited about this being my first auto grow. These things are really doing awesome I’m pretty impressed I don’t have any experience with them but I feel like they’re all pretty big for their size all of them are really starting to stack up bud. One of the jacks seems to be a few days behind the others in the flowering process. The jacks are both a lot Bashir and flatter the bubblegum and OG a really stretching out nice I love that shape of plant. Soil pH and everything keeps testing good no big issue so far I think one of the plants may have had some small nutrient lockout last week but I flushed it out good. I’ll update this week again soon or maybe not I don’t know thanks for stopping bye be safe ✌️.

Bueno familia ya finalizamos, estas red hot cookies son una cepa bestial. La verdad que el secado muy bien 7 días en Malla y a los botes, 45% humedad y 23 grados es la temperatura ambiental que han tenido en el secado. 4 plantas que se cultivaron en un armario de 1.20 pero estos ejemplares solo ocuparon 80x80. Así que ya está cultivada esta gran variedad que es novedad este 2020, americana de la familia Cookies, la Tropicanna Cookies (Girl Scout Cookies x Tangie) con un porcentaje de thc entre los 17/25%, una bomba. Que decir de Agrobeta, lo peta 💪 en cuanto a nutrientes. Un saludo y buenos humos.

Day 33 from seed : It is evident that this strain is a smaller phenon than the others in the grow room this round. 2 of the. are a decent size but dont show the growth rate of the others at all. #1 is the biggest of these wimmin , She was happy to be spread out more and will benefit from the amount of light getting in to her original squat structure.. Her paling is getting way better now and the Mc is not being fed to her now. #2 is the little lady of this group and will be left to grow up with only a little help along the way. #3 is a similar size to #1 but very very pale still. she has been getting calmag and mc so has improved more and doesnt seem to have been stunted by it.

I dryed them slow. I deleted the original report si i had to make a new one without all the data about watering and so.
