Great easy grow, took well to led grow and nutrients never needed to step back. Needed support fairly early on in grow. Heavy flowers not massive but I guess loaded with oils and good stuff. No apple smell or taste with these two phenos at all. Both super heavy chem affairs. One however tastes a lot like gorilla glue, it is one of the parents. This cultivar has shot straight to the top of my lists of grow again. It’s pure fire.

what a great strain! great yield and incredible scent! it grew very large buds, due to bad weather and high RH i sadly lost a few of the biggest buds, but still got an awesome yield

Aug 17: she is looking happy at the start of the fifth week since I started force flowering. Buds are forming and everything is on track. Very nice plant. Aug 18: nice enough day after a small bit of rain early. Tops are progressing nicely. Aug 20: hot and sunny so extra water again despite some rain last night. Aug 23: added another Scrog layer. This seems like a really good way to stabilize the plant while holding things in place for maximum sunlight exposure.

This was a great grow and only my second one so far. I am starting to figure out more about my setup and just keep learning things. My final harvest weights were more than I expected and I couldn't be happier!

Week 4 – Flowering (Day 22–28) 🌸🌱 At the end of Week 3 (Day 21) we carried out a deeper round of defoliation and some lollipopping. By now the stretch is coming to an end, with the plants settling close to their final height. We’ve also stopped foliar feeding, since every single plant is now covered in developing buds. To keep everything protected, we refreshed the beneficial insects, better be safe than sorry, how we say in German, sicher ist sicher. Already in this early stage of flowering, we can clearly spot differences in structure, bud formation and even the first aromas. Some phenos are showing exceptional promise — those will be the ones we’ll highlight more in the coming updates. 🔎 Pheno notes so far: AF Biostimulant 2 – strong side branching, open structure, already pushing citric aromas. AF 38 – well-built top colas, vigorous growth. AF 64, 92, 93 – impressive vigor, strong stacking, healthy canopy. Apple Fritter is already filling the room with fresh citrus tones and showing early winners.

This week is going really good, started seeing white hairs appear for it’s safe to say that it is beginning to flower, no scent as yet but will update as time goes on. Was eyeballing the height before but now I actually did it and it’s close or even passed 3ft now....this plant is growing amazingly.

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.

Unfortunately, one of the two seedlings succumbed to the intense sunlight exposure of a single day and exhibited classic signs of stress and stem damage, succumbing within the first week. With only one seedling remaining, I decided to proceed by faithfully following the established nutrient schedule. Here are the nutrients administered: May 8th: 250ml of water 0.5ml of RootJuice 0.5ml of BioHeaven 0.5ml of Activera EC: 450 nS pH: 6.5 May 10th: 350ml of water 1ml of RootJuice 1ml of FishMix 1ml of BioHeaven 1ml of Activera EC: 850 nS pH: 6.5

Day 37 12/12 everything was fine managed to kill of all the thrips no.sign of them now but another problem occured yesterday after lights off. Today i find a few leafs that are starting to yellow so i decided to up the feed ppm also the buds are still looking kind of small to me... are they going to fatten up yet or am.i being impatient or is there something wrong dont know wheather i should worry or not lol

Another Week Down – Things Are Moving Fast! Wow, another week flew by and we barely noticed! The plants are growing beautifully and developing nicely. One surprise this week: one of the Monkey Grease plants is definitely not a monkey... it’s a Gorilla Grease! 😄 This one is thriving — strong, fast-growing, and clearly the most vigorous of the whole bunch. It really stands out compared to the others, and we’re excited to see how it continues to develop! This week we also started light feeding: One watering with Fish Mix at 1ml/L (around 280 ppm) Followed by a watering with Alg-A-Mic at the same ratio (around 150 ppm) Both feedings were well-received, and the girls are loving it so far! 🌱💪
