This is my first grow in 25 years and it was a pleasure. Now that it's legal to grow 4 plants in Virginia, I did not waste any time getting started. Maintenance was easy. Well water in Autopots with Sohum living soil. All I needed to do was train the plants.

Gente,sono arrivato alla 6 settimana di fioritura,per fortuna sto riuscendo a debellare sto cazzo di ragnetto rosso...e tutti i fiorellini maschi che stavano spuntando...al momento sembra che non stiano più facendo sviluppare,ne nannars ne fiori completi di Maschio......il che è buonissimo 😋...spero riuscire a portare a termine bene la mia terapia, altrimenti mi ritroverò (ma di molto nellaCACCONA...MERDA!!!)..MA no! sono positivo e quasi sicuro che sarà buonissima 😋

D46 - The first day in the third week of flower. Not much to report. I'm pretty much just letting her go at this point, considering how stunted she is. I'm interested in what the result will be but I'm not really willing to spend much time or energy on her. D48 - I'm starting to see more discolored leaves on her, and I suspect that she has thrips considering that I had (have?) them in my other tent. I can't spray her with anything as she is in flower, and I already have a bag with predatory mites on her, so I've done what I can really can. In any case, she is more of a project at this point. The good news is that I think I have discovered why she is stunted. I read online about transplanting when they mentioned that it was important not to transplant when the plant is too dry, as it can cause the root structure to fall apart and thus shock your plant. Well, that is precisely what happened. During the transplant, my girl was dry and lost some earth, which disturbed the roots. 100% user error, as I suspected since this was my first time transplanting. Usually, I plant directly in the final container. I need more training (obviously), so I have started a new grow where I plan to transplant the girls a couple of times. D52 - The end of yet another week. She is getting frosty but is of course still stunted and tiny lol.

Weekly up date on these gorgeous ladies. They are stacked and swelling amazing going through the flower stage. I really couldn't be happier with how these have grown as it's an easy one not being to temperamental. I've kept the ppm/ec around the same between 900-1100ppms. Still feeding 16oz daily and all in all Happy Growing.

***** Week 6 December 23 to 29, 2020 - Days 36 to 42 from germination ***** Week 5 was certainly a stretch week and she grew tall baby👊👍 She has been doing well with her crack on the main stem from early on and when I pulled her out you could hardly tell where it was. Perfect......because she has been growing hard she is getting a little uneven in her canopy but I have been watching how hard I pull on her main stem. Correcting the situation as best I can now but with only in 3 gal pots its tough to get out further on her long branches and tie them down. Could get creative with Bamboo and creating ties but those suckers are eye pokers and I don't use them too often. Will just deal with the potential difference in height and keep pulling her harder now that I can. Silica increasing this week as well now that we close to the end of being able to shape her lower branches. She needs the strength now to defend any potential pests and to growth thick stocks so she can support the bud weight. Since she has been going hard it was time to pull her out and start trimming some lower branches now. Yes she is an auto and many say to never remove leaves, never mind branches, but I do and want to allow her to focus on top buds. I will accept a potential decrease in yield but since I am already performing LST and working with more than one top.....a gain in one area can be offset in another without too much pain😜👍 Stripped quite a few leaves from this girl. She is thick at the bottom and in the last week her node spacing has gone crazy on the 8 main branches😲 I will trim the bottom as it just doesn't get the light intensity down below......even with opening the canopy up lots those sites are still 12" to 18" lower than the tops at this point. Her side branching is really thick and looking awesome. She is showing signs of wanting to grow some big buds😀 She will be able to support the weight at least.........really nice selection Fast Buds!!!!!!! Little more detail........ Dec 23/20, Day 36 - Feeding day today. Continuing with first weeks flower feed of 2ml/L. - 2L feed with Micro, Bloom, Magnifical, AstroFlower, VeloKelp, Natures Candy @ 2ml = 800ppm and 5.8pH. - add microbes again on the next feeding!!!! Dec 24/20, Day 37 - She was given 1L of feed left from yesterday (both her and Orange Sherbet.......J47 is on a two day dry.) - Her color is good but still quite yellow in the new growth points. - pull out tomorrow and clean up lower growth and check runoff numbers. Dec 25/20, Day 38 - 2L full feed again with the same 2ml/L feed as earlier in the week for all the autos. Added AN Rhinoskin as well for silica. - 1150ppm and 5.9pH going in.........pots were really dry and perfect pretty well. - Runoff was 925ppm and 6.1pH.........I can live with that at week 2 flower😁😁 Dec 26/20, Day 39 - 2L full feed again. Had mixed up 12L yesterday. - Added 2ml/L of Microbial Mass and Piranha = 1200ppm and 5.9pH. - The girls needed their microbe allotment as we get closer to the end. - Bacteria added to help keep some of the nutrients in the media as she finishes. - next watering is more of plain water and add Terpinator. Dec 27/20, Day 40 - pots are light again in the afternoon. - 2L watering with Magnifical, Rezin, and Microbes @ 2ml. Terpinator @ 3ml = 400ppm and 5.8pH - She taking the nutrients but backing off the ppm on this watering a bit. - noticing some clawing in the girl.....start of some excess nitrogen or environmental??? Keeping an eye on it👌 Dec 28/20, Day 41 - the girl is hungry so feeding again today with full nutrients. - 2.5L watering today, stepping up from 2L volume. - Full line of Remo, all 6 parts plus silica again @ 2ml = 1150ppm and 5.9pH Dec 29/20, Day 42 - another feeding in the morning today. Pot was really light. - 2L in the morning giving with same feed of 1150ppm and 5.9pH. - her colour change in the leaves is really popping out now. Bud is all purple but the leaves are turning purple as well. - noticing leaf colour is getting even to the other girls for green. No need to compensate any deficiency anymore......in fact watch over feeding now😀 - in the evening, 12 hours later, pots were pretty light so gave another 1.25L of feed that was left over for 16L mixture yesterday. - she had a total of 3.5L feed today......water tomorrow and not feed. She is doing very well at the start of the week. Canopy height is good but her node spacing has me concerned a bit. Looks like we are going to get some beautiful colours from this girl as her buds are purple already. Leaf colour already has a yellow huge to her........Purple Lemonade baby......on point!!!!.......nice work Fast Buds.......this strain is making a lot of growers go, DAMN she's freaking awesome😁😁😁

6/1 I'm anxious to get my plants in their final homes. Another 90 degree day today and then it will be cooling off with some showers. I plan to take advantage and utilize that to make the transition. I have some small burns on a couple plants bit considering the weather we've had its nothing. Temperature swings 50 degrees. I hope these girls do OK outside. I was tired and stoned last night and I accidently topped a plant I had already FIMed. Oh well. Transplants soon. Supports screwed in after the heat. Plants have been handling this weather like a champ. Big thick healthy stalks. UPDATE PUT THE PLANTS IN AROUND 730. Cutting down on light hours I'm poverty close to where we are. It was 95 today. Plants have suprisingly little burning. My fan was taken so they go without that tonight too. In the next few days it's going to cool down and that's when I'll transplant. Only thing left before transplant is sanitizing trellis and supports. Easy peezy. Especially if it's supposed to be in the 50s. And people dent climate change lol. I'm hoping that all this adversity makes my flower a higher quality. I'm glad to have the quantity to pick the best phenos for the BIG POTS. Im trying to stay excited but it's just so dumb hot. Oh well. If the plants can do it so can I. I'm planning to give them some kelp me kelp you next watering and may start some light organic nutes. 6/2 Phone doesn't like uploading my videos. Broke record high temp yesterday 95 and tomorrow we will break the record low 50. Plants withstood the heat well and are doing great. Transplant soon. They were a little light but I held off on the water. Plan on it tomorrow. May transplant tomorrow. I have several videos that haven't uploaded. I thought they did but I was wrong. Oh well. UPDATE: Forgot to water. Some were light and others could've held off. Did the half a powerade bottle ahain. A litt ke less on the heavier ones. However I'm looking to transplant into final homes tonight and into this weekend. I sanitized a fifty and a forty so my bags and two pots are sanitized. Cage is sanitized and ready and pallets are sanktized and in place. The 40 and 60 fit PERFECT in the small space left from the pallets. Plus the plants always lean the opposite direction so things should go smooth. Only thingvleft is sanitizing stakes, bamboo, plastic garden stakes and all the other plastic training stuff. I'll just soak it while I transplant. Gotta mix the soil first too though. UPDATE. Heat went higher than expected and hit 90. I figured I'd go back around three and screw in suppirt stakes and begin getting everything ready for transplant (i.e. supports, mix soil, sanitize trellis) before I transplanted tomorrow MORNING was what I had planned. Unfortunately we got a huge thunderstorm with a shot ton of rain and it's gonna continue throughout the night. I think this is God's way of telling me to take a break. I can get up early and get those support stakes screwed in. Then when I get back from the wife's doctor's I can do the transplants. I'm trying to break the labor up into manageable chunks. Looking at my other diaries I can see that my plantscare fine in their three gallon homes. It'd a little disheartening seeing such big clones that I started so much earlier on the other diaries. However I always was fighting SOMETHING (usually more than one thing) and last year was a shit show. At least this year I stay away from anyone else's cannabis any clones and I'm extremely cautious. I've seen my cousin out perform me multiple times with healthy plants like this I'm excited to see how it goes. I really needed the break anyway but tomorrow morning the stakes will be in. Hopefully they'll be outside. 6/3 Broke the record for low days after breaking record for highs. I saw it 94 yesterday and the day before. On the way to my grow at 6am it was 44 degrees and it's not warming up much. Fifties at best. Rainy. I left the door closed. The big door on the otherside got opened as the other end of the garage neededcto he used. If the rain let's up I'm going to set up the grade stakes so I can transplant in the morning and throughout the day. I think I'm going to light dep a couple of them and leave them in the 3's. We'll see. UPDATE: At 12:30 the temp today was 44. Yesterday it was 94. I can't believe this. Plants are doing great though and are in the garage under lights for the day. The BIG door was open part of the day. Didn't take any pictures (or even enter the grow area) as I sanitized the last 40 gallon pot and a bunch of grade stakes. I drilled the grade stakes to the pallets in the front. The first row is done. Just need to sanitize the plastic trellis itself and finish attaching the other grade stakes. I don't need the fill trellis up by transplant. I just need the bags to not knock over and have SOME support. I'll be back over there either to tonight to put more supports in or tomorrow when I actually plan to start transplanting. I'm getting excited. After dealing witb the stiff that I sanitized I didn't dare go fuck with my plants so I looked through the window. I'll finish sanitizing the net tomorrow. These plants look great. I'm wondering if doing the two diagonal I poles with zipties actually works. It would save me some kone for sure. I'll definitely update in the morning. 6/4 It's warmed up to a balmy 44 degrees. My plantsxare in the garage still. Weather sucks this whole week but after this heavy rain it should be perfect weather to transplant these girls. A little to chilly but it will warm up and I need to get this shit done. I'm trying to do to much at once. I need to just out dirt in bags and get them outside. I'm glad I waited until after this craziness. Breaking temp records for high one day then breaking it for low the next can't be good for the plants. I'll update what gets done today. I may mix soil or I might wait until tomorrow. It will let up some then. Plants still look fabulous 👌 6/5 50 degrees still raining like hell. Rain until Friday. Plants are inside under the onecworking light. Lots of indirect light through the massive windows though. I'm planning on mixing soil today and tomorrow and getting bags and pots half filled. Just trying to break the labor up into manageable pieces. It's probably a good thing I didn't put them in their huge containers before all this rain. UPDATE: MIXED SOIL 1/3 of each (FOX FARM OCEAN FOREST, HAPPY FROG, AND ROOTS ORGANIC 707). I prepared I believe 11 containers for transplant. I need to sanitize two more containers and I'm good. I got a lot done. Might go back over. Set up extra cams too. I'm excited. Talked to my commercial buddy amd he motivated me. No reason my plants can't handle this shit. I've just had massive personal shit going on. Friday is the next GOOD day but these girls might go out earlier. I'm checking the forecast. I'll sanitize the other containers in the morning and fill them. 6/5 Today is usually my watering day but shit still seems heavy so I'm going to hold off. Despite that i need to transplant. I think they're wet enough. I could do it today. Plants are looking good and weather takes a better turn Friday. It's not raining hard though. It's just sprinkle right now. I may transplant some today depending on how things go. I'll keep the diary updated. UPDATE: I went back over with the intent to just mix soil and let it acclimate. I decided to try to transplant one. I grabbed a 10th planet and started to go. I had done a bunch of manual labor already so i wasn't thinking. Of course the fucker was dry and didn't wanna come out ofcthe pot and the root ball pretty much decintigrated in my hand so I'm not sure how that will go. Tried again with the Blueberry Cheese Cake. I thought the roots just might not have been rootbound abdcthat could've been the case. After having another rough transplant I recognized I was tired, all the hard stuff is done and it's gonna keep raining until Friday. I wanted to transplant three and put them outside but with the wind and rain and the difficult transplant I let them sit under the light in the garage in indirect light. I had the doors open for a while. Should be open now but i don't want to have to go back over and shut it. Plus I'm not to keen on getting water on my light. Let's hope for a better day tomorrow. This was the only thing I had going good. Phrple punches are still behind. I've decided I'm oing to light dep ttwo of the plants in the 3 gallon pots. The two shittiest or smallest plants (probably purple punch will be light deped. WENT BACK OVER AT FIVE AND IT APPEARS EVERYTHING IS ALRIGHT. WILL HAVE CHECK IN MORNING. Vid won't upload. Tried multiple times. I'll try again tomm. 6/6 Waiting for a doctor's appointment when I should be transplanting buy whatever. Everything is looking really good. Despite me disint9grating the rootball in my hands the two transplants look great! When I get back I'm planning to get some more work done. It's still lightly raining off and on but the door is up. I'm lettingvthe soil mix acclimate a little bit too. Hard labor is mostly done. Now the intricate part. Wish me luck. Not sure if it will be today bit I'm hoping. WENT BACK OVER CAUSE IT WASNT RAINING BUT AS SOON AS I WAS CLOSE IT STARTED POURING SO THE PLANTS ARE UNDER THE ONE WORKING 150HPS AND THE AMBIENT LIGHTING FROM THE WINDOWS. TOMORROW IS TRANSPLANT DAY. I WONT HAVE A VEHICKE SO IT WILL BE TRICKY BUT IM GONNA MAKE IT HAPPEN. Opened doors at 530. Video still didn't upload 6/7 Still raining. It's off and on and a nice rain though. It's 53 degrees at noon. I transplanted two 10th planet's into 20 gallon pots. I transplanted these two a little differently. I put the bags in there final spot I side my cage andctransplanted in the misting rain. The first one came out and seemed to be heavier on the bottom and broke off. I tend to "throw" them in the hole before they collapse. With my anxiety I suck at transplanting. Plus these plants haven't filled the 3 gallon pots with roots yet but i want hem in their final homes and its time to go outside. I transplanted the other two plants indoors and let them have days in the garage with the door open and the light on then protection from the elements at night. I've been doing this for awhile. They would all be outside if the weather wasn't so shitty. This rain is supposed to stop. I'm curious as to what will be the fate of the two plantsci transplanted and left outside. I'm praying and hoping for the best. I also put my back tarp up so I have a wind break between rhe buildings. I stopped working because I didn't want to fuck anything up. Anxiety disorders suck. TOOK A BUNCH OF VIDS BUT THEY WONT UPLOAD. GOES FROM 9% TO 65% BUT ALWA7S TURNS RED "FILE FAILED TO LOAD". I'LL KEEP THE DIARY UPDATED. ESPECIALLY IF I GO BACK OVER. WAS ABLE TO LOAD A COUPLE VIDEOS. I GUESS ITS NOT AS BAD AS I THOUGHT. AT LEAST I HOPE. WENT BACK OVER AT 3 AND CHECKED THINGS OUT. THE TWO REXENT TRANSPLANTS I LEFT OUTSIDE SEEMED TO BE IMPROVING. DESPITE THE FACT I DUMPED A SHIT TON OF SOIL ALL OVER ONE OF THEM. IT SNAPPED A LITTLE BRANCH CLOSEST TO THE SURFACE. ITS STUFF I'LL REMOVE ANYWAY BUT STILL. IM REALLY CROSSING MY FINGWRS AND PRAYING THESE GIROS WILL MAKE IT. With everything i have going on tjis is my respite.IM GOING TO TRY TO SEE WHAT I CAN ACCOmplish TOMORROW. SOME OF THE PURPLE PUNCHES ARENT READY FOR TRANSPLANTING THOUGH. I ALSO ADDED TEO TARPS TO THE CAGECTO COVER THE WIND TOWER BETWEEN THE TWO BUILDINGS. THIS IS GOING TO BE A GOOD YEAR! Shut the door at seven. For some reason the two 10th planet's I transplanted (that fell all over the plant and I thought mightve broke it) look awesome lol. Despite the ridiculous pouring rain. It's going to let up soon and we are do fir some good weather. I'm trying to get everything (that isn't getting light depoed) into the cage. Four transplanted. Ten (I mean 8 more) to go.

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.

This #40 and #42 plants from Ganja Farmer Seeds where the best out of them all, this is a bias review though as they where not all grown in the same bucket system as these two and thus could not grow to their true potential. The bugs where solid rock hard and crystaly They are true keepers if your wanted a good performing auto for shits and giggle outdoors. The major downside is how easily they got pests and how the pests preferred them over the other weed plants. this is a bit concerning to me and makes me wonder why. More to come. @GanjaFarmerSeeds, If you like the images or videos I can send you raw files that have not been shrunk and contain no watermarks, if you feel I am in the top 3 of your BDOTY Contest that is :D
