eek 1 Flower – Light Shift, Energy Shift: The Sundae Driver Flip Begins The light has changed. The rhythm has changed. And so begins the next phase of our journey with these two beautiful Sundae Driver phenos—F2 and F3, strong, structured, and ready for the path ahead. Light Flip: 11/13 Schedule This week marks the official light flip, we’ve moved from 18/6 to 11 hours ON, 13 hours OFF. This is more than a timer tweak, it’s an intentional signal to the plants. It tells them: “It’s time to shift your energy. It’s time to bloom.” Why 11/13 and not the classic 12/12? From past experience, this slightly reduced light period tends to: • Encourage faster onset of flowering • Mimic natural seasonal changes more closely • Push plants gently but clearly into the bloom phase • Slightly reduce internodal stretching, depending on strain It’s a subtle technique for growers who want to bring their genetics into flower with intention, not just automation. ⸻ Current Plant Stats Both Sundae Driver phenos are looking phenomenal: • F2 (Pheno #2): 7 to 8 solid nodes, well-structured branching • F3 (Pheno #3): 6 to 7 nodes, evenly spaced, healthy top growth • Height: ~40 cm each • Structure: Symmetrical, thriving, ready to stretch They’re not showing pistils yet—no visible pre-flowers, no white hairs, but that’s expected. It’s Week 1 Flower by light schedule, not by physiology. The hormonal shift has just begun. ⸻ Nutrient Shift – From Start to Top This week also marks a change in the feed program. We’re saying goodbye to Aptus Start Booster and welcoming Top Booster into the rotation. • Why the switch? Because the plants are transitioning from root-zone stimulation to pre-flower induction. • Top Booster is designed to: • Initiate floral development • Begin the phosphorus-potassium push • Provide trace elements aligned with bloom-stage signaling We’re using the same measurements as Start Booster, no shock, no surge. Just a clean hand-off, keeping the biological engine running smooth. Current Feed Includes: • Aptus Regulator • Aptus CalMag Boost • Aptus All-in-One Liquid • Aptus Top Booster (new this week) ⸻ Environmental Stats – Pushing the Edge, Managing the Heat • PPFD: 760 µmol/m²/s – Measured on the TrolMaster MBS-PAR sensor, dialed in • Temp: 31°C – Yes, a bit high, but the girls aren’t complaining • Humidity: 50% • VPD: 2.23 – High, but within tolerance while waiting for AC upgrade We’re riding the edge this week. It’s warm, it’s dry, but the plants are thriving, showing no signs of stress. Their resilience is a testament to your setup, your genetics, and your love. ⸻ Looking Ahead – What to Expect We’re now in the hormonal build-up phase. The girls are about to stretch, about to signal floral commitment. Here’s what we might see by next week: • First white pistils • Stretch kicking in • Top growth pushing harder than lower nodes • Nutrient demands subtly shifting—watch potassium and magnesium uptake What not to expect yet: • Buds • Resin • Drastic shape changes That comes soon—but not quite yet. ⸻ Closing Thoughts – A Sunday Drive Into Bloom This isn’t just a new phase, it’s a new pace. The grow has shifted gears, and you can feel it in the rhythm of the room. Light is shorter. Energy is tighter. But the intention is louder than ever. The Sundae Driver girls are leading us gently into bloom, graceful, balanced, and full of promise. Thank you for following along.

As I was planning to harvest this week, I started flushing Mishka with PH 7.5 water and no nutrients as per guidelines.

Ehiiiii ragazzii come va?? La settimana per queste due ragazze hibride F1 è davvero andata bene!! Merito soprattutto penso della intensità e qualità della nuova luce Mars hydro che posseggo e ringrazio vivamente di avermi dato questa possibilità di poter collaborare con loro e creare delle bellezze del genere che x me sono come pezzi di arte in evoluzione!? Non so se mi spiego! Per me sono la cosa più importante di tutta la mia intera vita! Chiaramente dopo la mia donna ,mia nonna e i miei gatti🐱🐱 apparte questo la genetica mostra una crescita uniforme dei due fenotipi Apollo nonostante la differenza di nutrienti... Vedremo nelle prossime settimane lo sviluppo delle cime come sarà , mi aspetto delle gran belle cime a giudicare dal verde bello intenso che hanno queste piante si vede che sono in ottima salute , e x ora x me preparare prima il terriccio e fare un soil living tra micorriza e nematodi mi pare l opzione migliore, a meno che nn compro tutta la linea Advanced Nutrients e allora nn avrò carenze nutritive! Se volete spedirmela boss di Advanced sono qua x testare se i vostri prodotti siano migliori delle tecniche che utilizzo io , preparando un terriccio organico, piuttosto che aggiungere troppi fertilizzanti minerali dopo.. a meno che ho tutta l ampia scelta di utilizzare tutti i prodotti specifici.. apparte questo ringrazio come al solito Mars Hydro e Royalqueenseeds che mi hanno dato fiducia x costruire tutte questo ! Buon 420 a tutti?! 😼💪🧙‍♂️🌱🌿🌲💨❤️❤️

Looks alright.😎

This was an easy and productive run. The 2 plants grew up in an overcrowded environment, and as a result, they did stretch a lot. Nodes were spaced but this wasn't a real issue since they both produced a decent weight. Fun/Strange fact: the TOPped one produced 77 grams and the FIMmed one produced 84 grams, very close results with two different methods. I took a clone of the FIMmed one, and it's already 50cm tall, almost ready to flower. The buds are compact and solid as a rock, the earthy taste is hard to describe but 100% unique and yummy. I'm totally in love with this strain!

She seems to thrive in the new soil, I'm checking her regularly because of the darker ridged leaves, could I have overdone the bloodmeal content? It should not have overfeeding effects with organic super soil. But we'll see. The FIM seems to have taken hold with her and today I started training, although it is more main-lining. For this, I just used some microwaved bamboo from the garden. Now we go towards flowering and I'm getting more excited after the first few weeks were a bit sad. Some of you might have seen my super soil recipe in my other grow, the Orange Hill Special, if you didn't, check it out here in the images! I designed it out of frustration that products like Fox Farms etc are not readily available in Europe. Those who saw my Gelato Monstercop grow, know that soil was pretty good, that soil became the base for this recipe, amended with some organic precursors to make it less dependent on feeding and after amending. I would recommend amending some before flowering starts without the bloodmeal. Hope you can use it!! Thank you very much for checking me out again this week! Hapy growing and big hug BioBuds and Sunshine

Prima settimana 👌

Week 8 Day 58, started flushing with plain tap water, no nutrients. pH 7.1. Experience a heat wave in the week (D58 to 61) which drove temperatures up, extended nyt time to 19 5, but even late evening it rose to 31c ( for upto 2 hrs before dropping to a steady 26c. Heat stress to some of the top fan leaves(curling). Orange hairs slowly! appearing. Very sticky, vanilla cream scent, it's coming upto week 9 D64, not sure if they'll be ready or will need another week longer? However, Not all cream caramels 'look' the same. Smells strong, sweet, vanilla cream

27.2.25: Watermelon 🍉 and Purple Lemonade 💜🍋 are both far below the scrog net, they've definitely stopped stretching now. My LST on these was much worse than even just using the net. 😅 That was certainly a valuable takeaway. I'm sure Purple Lemonade 💜🍋 will be good. Watermelon 🍉 was so stunted. It's not a tall strain, usually either, but nevertheless, the buds there are looking very frosty and are very, very sticky! 😅 Should be a good smoke, eventually, 🤗 just won't be much to bag unfortunately.

Wanted to show you guys a little bit of my first set up and the nutrients I’m using and I even put music behind it for all my stoners out there❤️ So about 2-3 days ago we transplanted and it was a fu***** mess . It was my first time so the coco wasn’t compacted enough and was falling apart but after the first plant I started to get the hang of it. Since transplanting I haven’t seen any huge growth like I did before transplanting and I’m a bit worried about some of my leaves are starting to get darker around the edges but still look healthy? And I don’t know what’s going on with these bright red/pink stems on top.. anyone able to help?

The fade is nice for the flowers colors they all have hues of purple but the b

Le 2 Fast Flowerg stanno crescendo bene e in salute, questa settimana ho dato solo acqua e zeolite per via fogliare, stanno rispondendo molto bene al super soil e alla luce, con internodi bassi e un ottima struttura..questi giorni vedrò se fare qualche potatura e settimana prossima qualche clone!

--------------- Start week 3 -------------- We started week 3 as we ended week 2, which is great. She continues strongly at the beginning of this week and seems almost unstoppable. She clearly enjoys her surroundings and looks very healthy. She has started preflowering and seems to be gearing up for another explosion in growth. She is very good at leaftucking and has already developed a good number of shoots. On to more! A new update at the end of this week. ----------------- Update Week 3: ----------------- End of another fantastic week for MBAP. This week was all about pre-flowering and you can see that she is preparing for an explosive bloom. She has benefited enormously from the LST that I applied and has a good number of shoots ready to explode during flowering. In addition to leaftucking, have also removed the lower shoots so that she can concentrate her energy on the upper shoots. I also did the biotabs in the ground in the middle of the week. We have opted for 3 biotabs in 20-25l soil. Have waited several weeks before putting the tabs in the ground because we work here with aitoflowers. And they prefer a light feeding regiment for the first few weeks. We are going to gradually lower the humidity and get ready for flowering and week 4! Until next update

10 días 12/12

63 days from start and 3rd day flower and started adding flower fuel bloom booster to the water... 67 days 7 days flowering with second half of pics and 2 videos

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.
