Que pasa familia, vamos con la septima semana de floración de estas Black muffin F1 de Sweetseeds. Vamos al lío, me quede con 3 por espacio, siempre pongo alguna semilla de más por si no abriese alguna por no perder ese hueco del indoor. También se trasplantaron a su maceta definitiva, en este caso de 7 litros y el trasplante se realizó correctamente. El ph se controla en 6.2 , la temperatura la tenemos entre 20/22 grados y la humedad ronda el 50%. Las jodidas han estirado bastante, ya veremos que ocurre como va todo. Hasta aquí todo, Buenos humos 💨💨💨

Week 18 Middle August : weather is changing. Return of heat and humidity: 28 degrees, a little bit rain. A heat wave is coming but near the ocean the maximum will be around 32 degrees. It’s good to grow in greenhouse during this period : -ventilation control: I adapted the rythme: for now it’s around 18h/24h intermittently -pests and diseases control: insect’s traps natural and artificial, less heat -humidity control: no rain problem Daylight 14h: 7h/21h Flowering time 😁. Healthy plant, beautiful green color, just a few yellow leaves on the base. More watering: 1,5L every 60 hours Same cocktail: Calmag (0,5ml/L)+ FloraGro (2ml/L), FloraMicro (2ml/L), FloraBloom (1ml/L) + Root booster + Cannazym Feeding soil with guano bat (NPK 3/6/10) for a slow dispersion + dried horn and blood (NOK 13/0/0) for nitrogen add. Protecting plant: sprayed Neem Oil, added diatomaceous earth on soil. I will make a defoliation soon.

Start of week 7 for the OG Kush and blueberry. Second repeat of week 5 feeding for the super lemon haze as she's on a 10 week schedule. OG's are super sticky, smelly and packing on thick dense buds, blueberry is bulking up, but not nearly as much as the oG. The SLH is also pumping out nice buds, that are very sticky. Very happy with this grow so far.

Flushed them as I think they are only a week or two away from harvest. They are getting really heavy and as I had to move them to the shower to flush them properly I tried to be careful not to break any branches. The PH is about 8.0 of the tap water, so after flushing I gave them enough PH 6.3 water. One or two plants seem to be finished, they already have some dark trichomes - but I can't harvest them as I only have this tent. As always - if you have any advice for me or criticism, please let me know! Thank you! EDIT: Humidity is currently a huge issue, there has been rain 24/7 since yesterday, so keeping humidity at oround 30-40% is impossible. Currently at about 55% - I know, it is too much but there is nothing I can do.

Introduction - Week 09 Summary - Ensign's log, stardate 100906.68, Overall a pretty good grow week! Started the week off by increasing the light's intensity. Also raised it up a bit. Most of the week was basic growth checkups and humidifier refilling. Mid week, increased the light's intensity a bit more. Also did a top soil drench of organic fertilizer along with a simple defoliation. Towards the end of the week, decided to give both girls a large bottom watering. Also did a mini defoliation again. Now that both reservoirs are full with about 2 gallons, shouldn't need to water for a while. Next week will be the big 12/12 flip! Steady as she grows Ensign.

[END OF WEEK 09]

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.

Trichomes and strong smell. That's what we like 😋😍 👆 Largest plants = Triple G = 125cm 👇 Smallest plants = Wedding Gelato = 85cm

Great nose and terps. Cookies beats out Humboldt in quality. Yield was very low but that could have been growers error

Week 8. They got their First flush. Look at those beauties. Better pictures by the end of the week.

Another week of sunny weather. The training went well considering the outdoors. At the end of the week the stamens showed.

This week was hottt. I have been out sic l8ly sorry 4 no updates. The girls r still growing strong. With very little maintenance. I gave them each 5 gallons of water with nutrients on Sat, (early morning since it was a heat wave) I defoliated (the lower branches became shaded out) and now the little bushes are taking upon a more tree like appearance. They are all just under the 7 ft roof, with training. They were hitting the roof and getting wet (morning dew), so i put more fans inside, (also the 90+ outside temps). No problems with heat. I will start making preparations 2 switch them 2 flower at the end of this month :)

A couple of weeks until we are done 😁🔥

half way through the first week of flower and the stretch is in full effect. canopy is going to be completely full in a few days, scared for my dwarf white runtz in the middle of the group, itll get swallowed

I love the sativa shaped nug-towers! When my plants grow big, I like to grow them until the very end of their cycle! That's why the extended flower period. Video of Measurement of yield: T=Tops(92grams), M=Mids(59.1 grams), L=Lowers(58.6grams) Total: 209.7 grams (1-2 grams worth, was taste-tested prior to scaling.)

Heute ist Tag 28 und den Pflanzen geht es prima. Die MAC#1 hat zur Mimosa etwas aufgeholt und die Tropicana Cookies geht voll aus dem Rohr. Sie scheint schon deutlich weiter in der Entwicklung zu sein und ich bin gespannt, ob sie groß oder schnell fertig wird. Vielleicht ja sogar beides 😅 -------------- An Tag 32 musste ich entlauben, da ich die Triebe nicht einmal mehr von Hand an den Blättern vorbei bekommen habe, ohne etwas zu beschädigen. Dieses mal habe ich mich dazu entschieden, einmal recht radikal zu entlauben, anstatt wie bisher jeden Tag ein bisschen. Ich möchte mir dadurch Zeit und Arbeit sparen und hoffe, dass sie das gut verkraften. Bei der Mimosa bin ich mir da nicht so sicher, da die unter ihrem Blätterpanzer ziemlich klein geblieben ist. Die Äste sind aber sehr dick, also wird sie vermutlich jetzt 2 Tage schmollen und dann nochmal loslegen, hoffe ich jedenfalls 😅
