So after our first attempt went down hill pretty fast, we wasted no time in putting another bean to sprout.Here we go! Attempt #2 11.08.2020 - bean started showing first sign of life 12.08.2020 - she started opening up. 19.08.2020 - leaves started burining at the tips again.maybe i removed himdity dome too soon so it was placed back on 2 days ago

I made so many mistakes during this run I can't even believe we made it to this point. The flowers aren't great but they're aight considering. I tested some run off and ppm was 3000+. I was consistently hearing the condensate pumps go off which made me think I was getting run off not realizing it was from the dehumidifier. The pics were taken on Thursday and after 2 days of flushing they look better and have swelled up a little bit. I sprayed dr zymes for the thrips 3 days in a row to try and knock them out. I know spraying in flower is never great but the zymes evaporates and really had no noticeable negative effects on the buds (pistil burning or residue) and I havnt seen a thrip or any damage in a few days. I also got the full line of Marrone bio grandevo, venerate and regalia which ill incorporate into a weekly ipm starting next run. I'm gunna wash the buds at the end. Hopefully all the dumb shit I do this run I can learn from and improve. Day 49 I've dropped the base nutrients and have them on 8 grams per gal of full tilt with some aptus additives and enzymes. The multi strain makes it tricky as a few really need 70-80 days but at this point I just want to wrap it up asap. I'll hand feed the 3 or 4 plants that still need the base probly.

Hello it's another week of Passion of the Widow! Like I suspected there are 3/10 seedlings that are expressing mutations and or stunted. So I'll be getting rid of the runts (ww 8 and ww3) since I'm looking for a breeding pair I don't want stunted or mutants for the process. The girls are looking good, though I'm getting early pest problems which I just sprayed for earlier (:

Dec 26/Day 16.25 @5pm: LST begins and at 8pm 1 top leaf defoliated for light penetration. Dec 26 @10pm: Turned bloom lights off (cobs) and left veg lights on. Lowered lighting to 12". Broke her main stalk and taped it. EEEE Giving her a short break from the heat and time to stretch while I LST her. Her humidity levels are up around 54-60% with cobs off and humidifier running. Dec 27/Day 17 @4:20pm: Both cob and veg lights are on again and the light hangs 12" above. Dec 27 @9:30pm: Watered her with 2.5L at a PH of 6.56, soaking the whole pot through for the first time. PH runoff was 6.71 This week, I started watering daily with 0.4L and by week end about 0.75L at PH 6.6-6.7

Such a great week watching these ladies bulk up! It's looking like the gorilla zkittles won't get a full week on its current food schedule before I start it on its winter frost and flushing. The Red diesel and Phantom will probably take another two weeks on there food schedule. Happy growing people! I wish I would've started this grow sooner, then I wouldn't of ran out of stash during this quarantine!

-Grow is going great. Swelling up -I've been dropping the temps and humidity down during lights off. The temps don't drop below 66 degrees and I try to bring the humidity level down to 30-35% several times throughout the dark period. -Starting my flush. On my hydro plants, I will be using florakleen and hydroguard in water with a ph level of 6.0-6.2. -Flushing the plants in coco with ph balanced water and blackstrap molasses for the remainder of the grow. A nice experiment to see what difference it makes.

This week, spent a little more time on the garden, Transplant, microbes on the soil, new 20 litres pot, and every day bending, to mantain an homogeneous canopy ... Fed some Green Explosion again because i want a little more branching , but im switching next week to Flowering nutes, but imma keep Veg nutes because autos seem to keep growing more when switchin ... But heyy im new with autos hahaha lets see what happens.... The plant is soo healthy at the moment :) --------------------- Micro Vita : Applied 6.60 grams for the 20 litres of soil, recommended is between 2-5g per 10l .... TopVeg: 2,5 ml when applied alone and 2 ml/l when used with Deep Underground or Green Explosion. Green Explosion: 0,5-1ml/l, always with TopVeg because of PH balance Deep Underground : From 1ml/L first weeks, and until now, 2ml/l. Irrigations : Everyday in the morning, alternating 1/2 with water and the other with nutes, but if the plan is dark dark green im irrigatin only water so id would be 1/3 in that case. #####Top Veg always balances the PH so im never using boosters without it (they have high ph like 8 - 10 ) --------------------- Take care GD !!! Good vibez...

Start of Week 11 - Day 71 07/12: It seems as if Annie’s stretch is slowing down. She’s now at about 30” tall and she has a lot of colas poking out from her base. Aaliyah and Alexis have stopped their height at 34”. Alexis’s buds are starting to get bigger. The buds in Aaliyah’s main cola are starting to connect and are also getting bigger. Aaliyah’s bigger buds are also getting coated in trichomes. The smell is still pretty minimal. Based on the visual changes it appears that Alexis is about a week behind Aaliyah and Annie is about three weeks behind Aaliyah. Since this is my first grow I’m not too sure on harvesting time, but I’d say Aaliyah will be ready first and she still has a few weeks left in her. They are losing some leaves closer to the base, but they are looking amazing overall. It’s hard to believe it’s been 70 days since I put the seeds in water. Time really flies. 07/16: Playing the waiting game and it isn’t easy, but it will be worth it. The ladies are at different stages of flowering, so I’ve decided that next week I’m going to start giving them different doses of nutrients.

31 Aug. I start the third week of my autoflower. The plant is growing well, but I noticed small yellow spots on the leaf tips, which seem like a mild calcium deficiency. This is probably due to the fact that so far I have been giving water with a slightly low pH, around 6, while the ideal range would be 6.5–7. At the beginning, to lower the ppm of the tap water (which was around 211 ppm), I mixed it with demineralized water. This brought the ppm down to about 109–140, making it harder for the plant to absorb the available calcium. Additionally, the soil I am using, Biobizz Light Mix, is lightly fertilized but does not contain enough calcium to correct this small initial deficiency. For this week, I will not add any fertilizers. I simply want to raise the pH to 6.5 and use water with higher ppm, so the plant can better absorb the nutrients already present in the soil. The lamp is positioned about 35–36 cm from the plant and so far there are no burn issues. Temperatures range between 25 and 30 °C depending on the day, while humidity in the room stays between 40–60%. The humidifier is always on because I keep the window open, but the dehumidifier is not being used, as it is not necessary at the moment. I also have a new oscillating fan arriving to replace the current fixed one, and I’m waiting for a regulable extractor (90–145 m³/h), which will allow me to control the air perfectly during winter if needed. This week my main goals are: Increase the water ppm without overdoing it Adjust the pH to 6.5 Keep observing the plant without adding any fertilizers Everything else seems fine and growth is regular. With these corrections, I expect the new leaves to grow healthy and free of spots. ==UPDATE 31/08== To control the calcium deficiency, I will administer an eggshell solution until I reach 300 ppm (I will boil some eggshells and administer the solution in tap water).

Some of you may have wondered: Why do I use CO2 at average 950 ppfd μmol/m2/s (moral flow)? The answer is quite simple. Because of lack of space in some regions of my cultivation area, I simply cannot keep the ideal distance to my Sanlight high-performance lamp, due to some height growth of various strains. And so some of the main colas have ppfd values of 1250 μmol/m2/s and even more... So this is how I manage to achieve and compensate for such high radiation levels even with a CO 2 balance. And I have to say, my strategy to avoid various light stress symptoms works just fabulously. In combination with CO 2 implementation, my babies are simply unbeatably insensitive to light. Thats it! Beginning of 3rd week flowering: Again feeding my babies by 36 hours fermented potions of Bio Tabs Kompost Tea PK-Booster (15 g pro Liter) and added: 5ml Orgatrex/Liter 1 Spoon of Bactrex 1 Spoon of Mycotrex 1 Spoon of Mycco-Vital 1 Spoon of Dynomyco A little tip for those who are interested in small modifications that have a big difference or influence - on the result - effect - beauty - health - taste! Before adding microorganisms or beneficial bacteria or Mycorrizae and Trichodermas, please use oxygen-saturated water. On the one hand, unwanted chlorine gases evaporate and the small world of the microbiome becomes even faster and more rewarding in compost tea to sprout. Last but not least for this week, I would like to introduce my reasons, why I prefer growing biologically and sustainably. First of all, it’s something which suits very well in these times/days we are living now. Sustainability is a big need and task for our planet. 🌎 Nature means life. Our home, the air we breathe and everything that surrounds us. Not just today. Hopefully tomorrow as well. Maybe I'm starting to protect our environment on a small scale, but maybe I can also make a big difference at all. If you change the way you look at things, the things you look at change... I thought about what’s the difference, between Mineral Feeding and Super Soil Feeding. It’s very easy. Biologically Growing is a similar process than the natural soil activities out there in the lap of nature’s. So plants has to work and interact with the microorganisms and microbiomic communities in the soil. So the plants will never get lazy like the lazy ones of mineral feeding growers. If you grow biologically, you will feed the soil first and the microorganisms will support every parameter next to your plant conditions. And that will generate an unbelievable spectrum of Terpenes and Trichomes you will never forget. It’s the same comparison, when you daily visit McDonalds and you eat only fast food. How does your body and mind react on this shit for money?!?! May I invite you to think about it… See you next week dear Growmies! Have a nice Weekend and take care… Peace out! Addendum for Day 53: At the moment we unfortunately have another winter onset here in Germany. This means that I am forced to take additional heating measures due to structural facts in order to be able to keep the temperatures constant. After all, just tonight the thermometer climbs again to -1 degree Celsius. In addition, my exhaust air system runs out of my bedroom terrace and I therefore grow winter and summer with the patio door open. Well, sometimes I experience real weather-related challenges. But all in all, no problem... "Where there's a will, there's a way." Addendum to pouring out the fermented PK tea: I always administer half a liter of lukewarm aerated water with 3.5 ml of cannazyme per liter to each plant. This means that the "root machine" is not supplied with supplies unprepared and the nutrient solution can thus also be better distributed in the soil. Since I also work with cloth shoes, I spray them evenly moistened everywhere with water that is also warm before pouring them out from the outside. This has the advantage that the moisture stays where it should: in the pot! ... I did the math today ;-) We are still in week 7 until this Friday. And week 8 starts on Friday! OMG... still so much time yeahh! Today my Fast Buds Sour Jealousy and Sweet Seeds Big Devil and Dark Devil Automatics arrived. I'm looking forward to it. This time Fast Buds next Time Sweet Seeds. Love them too. Very beautiful genetics. Today a review video of the beginning of week 3. At the time of the pictures, I had minor signs of nitrogen excess. (Light peaks first at the crown of the roof and then slightly continuing to the middle section.) I then painstakingly racked my brains as to why this could be. I found that very slight dry spots had formed and therefore the root found small accumulations of nitrogen that caused its problems. But then, when I carefully homogeneously checked the moisture content in the substrate, the problem evaporated again. However, they had not shown any loss of growth rate during this time. Nevertheless, they developed as expected. They Strawnanas had no problem with that. In the end, I always have a hard time killing them. But I guess that's the way things go. We live and die. We come and go. But it's not there yet. ;-) Tomorrow is day 56. Tomorrow’s updating day! Can't wait to see their progress. Have a good time and see you tomorrow… 🏽🕊️ 🏽 ☮️🕊️

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.
