Had a few issues this week mostly with ph runoff, was very high at 8.5 (had been on the rise for a little while given that I have been time poor and a lack of energy this was put on the I’ll do it tomorrow list). Picked up some drip clean and reset the coco. Now getting runoff at 6.4 and improving. The girls have been growing this week some more than others but overall I’m pretty happy with the progress shortest being 36cm tallest 67cm with most averaging 53-55cm. Picked up 2 more fans to keep the air moving and will be hopefully doing some restructuring of the tent to help reduce this humidity and potentially relocating 4 of the girls into the 1.5x1.5 tent to give them all some extra room Other than that just maintaining the light into the plants and trimming where required all be it in stages when time allows Potentially too late in this grow but have moved over to filtered water to remove chlorine, tds remains at 87 for tap water and filtered water but filtered there is 0 chlorine Have dialled up the lights from 45%/45%0% to 45% veg 60% bloom 0% uv for another 6 days if all is looking good will ramp to 60% veg 80% bloom for week 10 and checking for light stress. Have an overlap of 20cm in the hellion vs3 lights which is going to give the centre a bit of punishment. Also looking into putting some co2 grow bags into the tent so the plants can handle the extra light. After 12 hours of increased light there does not appear to be any light stress yet

Hello my friends! Almost weekend, are you ready for it ? I can't wait, the work drained me soooo much this week! Good that this little Titan gives me so much joy and satisfaction every time im back home! Back to us! Today is friday and marks the last day of her 10th week. Today is kinda important, is exactly 77 days since the plant showed up from the soil. RQS is saying that normally this plant is ready to harvest in about 70 to 75 days. Mine is already 77 and is not ready yet. As you can see from the picutres and clips especially the last ones of this week...you can see that her trichomes are not quite ready yet. The trichomes look like they are 85%/90% ready right now, as I am writing this post. The pictures and clips are also from this morning, is all fresh material. Most of the trichomes are cloudy but you can still see that few of them are not ready yet, also there is no amber colour at all. All of this it must mean that the plant can go couple days more. This week and the previous one I was reading and checking online about this plant and her previous grows. I understood that the plant in reality takes a little longer to get FULLY ripe and ready. A little over 80 to 85 days. I will let her run for another week more or less, today is day 77. For peace of mind I am checking the trichomes every 2 days to don't miss it or be late. It would be a shame to cut it down right now. Why? I can see the buds getting bigger and bigger everyday! She's getting thicker literally in front of my eyes, especially in this late phase of flowering. I can see the buds increasing in size day by day. I am sooooo happy! Dope! So harvest probably next week! WATERING This week I've started the FLUSH cycle. The plant got 6 L of plain water adjusted to 6.3 pH and splitted in 3 watering sessions by 2L each. In all 3 waterings the drained water was around 1 liter. NUTRIENTS No nutrients this week, same story next week. Just plain water till harvest, the water will be adjusted to the correct pH. No more no less. The harvest should fall exactly on the day that marks 2 weeks of no nutrients. So actually with this we are really spot on! Perfect I would say. LIGHTNING The light is always 100%, 24/7. The only update here is that at the beginning of this week I lowered the light about 10 centimeters for this last days of flowering. Is an experiment...anyway my light is only 70 watts in the end. So I am not too worried about it, probably I should lower it couple of week ago to give that extra boost to the plant. But it is what it is, now is too late ahahahah. Anyways talking about the light...before I've got 25 centimeters between the led lamp and the plant, now is about 15 centimeters of distance. TRAININGS NO MORE training techniques were applied to the plant. At the beginning of this week I REMOVED all the LST that was trapping and keeping her strapped to the pot. I wanted the plant to BE FREE during the last two weeks of her life. Like a little treat and mercy for this beautiful prisoner ahhahaha. Removing the LST I allowed the plant to lift up a little bit more her branches. In this way the buds sites went up and closer to the led lamp, closer about 10/20%. Maybe is not much but in the end everything counts on the scale. We will see the results. The height of the plant didn't change in this last weeks, it reached 48 cm and stayed there. Actually after I released her from the LST last week, it gained 2 cm. So now at the end of her life the plant is 50 cm tall. The smell is strong and pungent, refreshing somehow. Very pleasant, I love it. OVERALL Everything is going well, just a little bit late on the schedule. The patience is the key for good and big buds! I CAN SEE THE FINISH LINE, WE ARE ALMOST THERE. See you next week for the final update! Stay safe y'all!

Day 57: Watered every plant with 1,0 l of fertilized water. Advanced Nutrients Overdrive only for #3 and #4. I think I will harvest these two after week 10. Day 58: Nothing important to do... just sat there for an hour, watching the ladies grow, and collected some fallen yellow leafs. Day 59: Watered every plant with 1,0 l of fertilized water. Advanced Nutrients Overdrive only for #3, #4 and #5. Day 60: Nothing special to do. Day 61: Watered every plant with 1,0 l of fertilized water. Advanced Nutrients Overdrive only for #3, #4 and #5. Day 62: Did some defoliation on #3, #4 and #5. Day 63: Nothing to do today.

Removed 20l from the reservoir and filled it up with fresh nutrients. Added Yara Kristalon Orange, Yara Calcinit and a little bit of Haifa GrowClean to the reservoir. Adjusted PH/ORP, PH- adds P and ORP adjustment adds K. Topped it up with tap water every second day, the dehumidifier pulls ~12l/day, most of it should be from the plants I've got in my tent. I am struggling to keep ORP at ~100, might be a sign of root trouble. Nothing else to report. Values are average of the day.

The summer was super wet and humid so she lost 2 of the big buds to mold. Other than that she did great! really big, vigorous and heavy, dense buds. All arround winner. Really looking forward to the seeds. These plants are not mine. I am just documenting them. Total Runtime: 81 days -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Set up cost (fixed costs) -Lamp: 40€ -Timer: 3,5€ -Pot: 4€ -Total fixed costs: 47,5€ Given 5 years (or 15 grows) usage time translates to around 3,17€ per grow in materials. Variable costs: -Seeds: 13,17€ -Soil: 6,00€ -Fertilizer: 3,50€ -Power: 21,00€ -Total variable costs: 43,67€ -Total costs per grow: 46,84€

Day 10: They have been growing nicely. Beautifull green leafs, no deficiencies or stress. I did some Defoliation and I'm planning to top some plants but not all of them since they make nice main colas as well. Also nice roots so far, will let those grow for another 1-3 days before repotting them into 7L pots. While doing that I will add some new clay for beneeth the pots to have a good run-off. I will add some mycorizza as well to improve the roots and I will water them again with lots of Regulator(anti-stress) and Rhyzotonic( root stimilator). Some days after that, they are ready to get pushed into flowering. Sativas like to grow twice and sometimes even more in size. So the size which they are at the end of this week will be enough. So at the end of this week you will see them being in 7L pots and in a bigger grow space under lots of lamps. There are like 3-5 plants not growing nicely. Might have to kill them. I'm not going to waste time,energy,nutrients on those if they don't grow in size in a couple of days. So might end up with just 235 plants. Il update again at the end of this week. Day 14: I almost finished the rest of the grow room. I still need to adjust and replace the lamps some more and other things. Did many defoliation below the plants. Thoose branches are never going to preduce nice and thick buds anyways. Such a waste of energy and nutrients. Because of the removing of branches and leafs, They get a better airflow and better exposure of light as well. So for now they look a little bit ugly haha and not so bushy anymore, but they will grow into fine looking ladies. I kept 5 or 7 branches each plant and some bigger plants I even topped because I don't want them to stretch alot. Another reason is that I want bigger stems. If other plants that didnt get topped, not improving stems I can still top them until the end of week 1 of flowering. I'm putting them into flowering, by putting the lightschedule to 12hours of light and darkness. It will take a few days before they start preflowering. The first buds will be seen in like 10-14 days. Untill next week!

Day 79, 28th of November 2020: Hi there! Here we go let's say half way. Plants are pretty these Original Sensible Seeds genetics are fantastic! The 2 OG and the Runtz Gum is very strechy. Black Ghost is pretty shorter bushier plant. Runtz Gum and Do-Si-Dos OG approx the same height Do-Si-Dos OG is taller a bit. Wedding Gelato is really cool little, bushy anf nice buds forming not problem with her all she is quiet. Do-Si-Dos OG has some deficiency and leaf gets dry but nothing very serious..... Fertilization is still the same every second day with the rationand mixture above stated. The lamp is on 11.15 min and off 12.45 min. Last week was 15 min longer light cycle.... So every week 15 min shorter light cycle until the 5th week. So far -45 min. It switches on at 6 am and off at 17.15 pm.

Mid week check in with grow issue (mostly on the Future #1 and Future Island - other strains in my grow room). Will post for feedback. Held of on any nutes this week as I try to get my grow issue under control. Looks like either calcium or potassium or both. I initially bought some lime and added that to some well water instead of the RO water I had been using. I also fully flushed out all of them in order to ensure that I didn't have any lingering issues. A little unsure how it got to this point as I have used RO in past grows. My RO is barely 6.0 ph and the well is well over 7...closer to 7.5. I had not changed my diary's ph since veg since I think I had mixed up the reading between the RO and well water. Either way, I plan to feed them all well water and balance the ph to 6.5. Except for some of the leaves showing some stress, the bud development is looking very nice. I plan to ease back into a more reserved nute blend later this week. Trying to get the humidity under control but with the excess heat the humidifier gives off it has been a bit of a struggle. Going to set up the unit on a timer so it dehumidifies at night where there is less heat in the room. Plant #1 - Continued fattening of the bud locations as well as more turpentine development. Looking good. Plant #2 - no more stretching, bud development is coming along just lagging behind a bit.

🌱✨ Super Sativa Seed Club Week 5 (Pre-Flower) Report! ✨🌱 Hey fellow green thumbs! 🌿 We’ve just wrapped up the first week of the flowering phase with our Auto Fast Pete and Auto Northern Dragon Fuel from Super Sativa Seed Club. This week has been all about preparing for an explosive flowering phase and optimizing our grow environment. Let’s dive into the details! 🌟 Week 5 (Pre-Flower) Progress: Day 29-31: Transition to Flowering • Auto Fast Pete: Our fast-growing friend is transitioning beautifully into the flowering phase. Pistils are emerging, marking the beginning of bud development. The plant is showing strong, healthy growth and a robust structure. 🌿🌸 • Auto Northern Dragon Fuel: This resilient plant is also entering the pre-flower stage. The first pistils are visible, and the plant is stretching and preparing for full bloom. The vegetative growth has set a solid foundation for a bountiful flowering period. 🌱✨ Day 32-34: Room Organization & Autopot System • Room Setup: This week, we reorganized the grow room, placing our Auto Fast Pete and Auto Northern Dragon Fuel to the far left of the tent. This strategic placement ensures they receive optimal light and airflow. 🌿💡 • Autopot System: We turned on the Autopots, an innovative system that automates the watering process, ensuring the plants receive consistent hydration. The Autopots use gravity to deliver water from a reservoir to the plants, allowing them to take up water as needed. This method promotes healthy root development and prevents over or under-watering. 🌱💧 Day 35: Nutrient Changes & Environmental Conditions • Nutrient Strategy: We’ve stopped direct feedings and are now testing how the plants do with only the organic nutrition in the soil, supplemented by regulator and CalMag in the reservoir. This approach aims to maximize the benefits of organic soil nutrition while ensuring the plants get essential minerals. 🌿 • Reservoir Details: • TDS: 400 • Temperature: 18°C • pH: 6.2 • Environmental Conditions: • Temperature: 31°C • Humidity: 51% These conditions create an optimal environment for flowering, ensuring healthy development and growth. 🌡️💧 🌟 Care Tips: • Light: Keeping our full-spectrum LED light at an optimal distance (18-24 inches) to ensure even light distribution. The plants are responding well to the consistent light schedule. 💡 • Autopot System: The Autopot system ensures a steady water supply, reducing the need for frequent manual watering. This system is great for maintaining consistent soil moisture, which is crucial during the flowering phase. 🌊 • Nutrient Monitoring: Keeping an eye on the reservoir’s TDS and pH levels to ensure the plants receive the right amount of nutrients and minerals. This week, we’re focusing on organic soil nutrition supplemented with regulator and CalMag. 🌿 • Environment Control: Maintaining a stable temperature of 31°C and humidity around 51% to create the perfect conditions for flowering. Adjusting airflow and positioning to optimize plant health. 🌡️💧 🌟 Genetics Spotlight: Auto Fast Pete: • Characteristics: Rapid transition to flowering, strong structure, early bud development. This strain is a reliable and fast-growing option for any grower. • Future Expectations: Swift bud development and resin production in the coming weeks. Anticipate a dense and flavorful harvest. Auto Northern Dragon Fuel: • Characteristics: Resilient transition to flowering, robust structure, visible pistils. This strain promises high yields and resilient plants. • Future Expectations: Significant bud growth and increased resin production. This plant is gearing up for a heavy yield. 🌍🌿 Fun Fact: Did you know? 🌿✨ Autoflowers begin flowering based on their age, not light cycles. This means they transition to flowering typically around 4-5 weeks after germination, making them a great choice for quick harvests! For all the in-depth action and detailed explanations, head over to my YouTube channel! 🎥✨ I’m sharing all the tips, tricks, and step-by-step guides to help you get the best results from your grow. This week has been particularly exciting, and there’s so much more to explore and learn together! 👉 Join me on YouTube Link is in my profile 👈 🌟 Conclusion: Week 5 marks the beginning of the pre-flower phase, with both Auto Fast Pete and Auto Northern Dragon Fuel showing promising signs of bud development. With the Autopot system in place and our focus on organic soil nutrition, we’re set for an exciting flowering period. Stay tuned for Week 6, and happy growing! 🌿💚✨ #SuperSativaSeedClub #Week5Report #FastPete #NorthernDragonFuel #PlantMagic #GardeningJoy #NatureLovers #PlantPower #Inspire #GrowYourOwn #YouTubeChannel Germination method 🌱 @thecannakan Genetics @supersativaseedclub_official Nutrition @aptusholland 🌿 @aptus_world 🌎 @aptus_es 🌍 @aptusbrasil 🌱 @aptus_thailand 🌿 @aptus_portugal 🌳 @aptususa_official 🍀 @aptusplanttechnz 🌺 @aptusplanttechaus 🍃 Ambient controls🎮 @trolmaster.eu @trolmaster.eu.support @trolmaster.support @trolmaster.agro Soil @promix_growers_eur @promix_cannabis LED - @lumatekeu Watering- @autopot_usa @autopot_global Love and attention- @dogdoctorofficial As always thank you all for stopping by, for the love and for it all , this journey of mine wold just not be the same without you guys, the love and support is very much appreciated and i fell honored and so joyful with you all in my life 🙏 With true love comes happiness 💚🙏 Always believe in your self and always do things expecting nothing and with an open heart , be a giver and the universe will give back to you in ways you could not even imagine so 💚 More info and complete updates from all my adventures can be found ⬆️link in the profile description ⬆️ Friendly reminder all you see here is pure research and for educational purposes only 💚Growers Love To you All 💚

Welcome to my sponsored Green House Seed Diary. Thanks for dropping by, drop a like if you'd like me to drop by your diaries, either way thanks for dropping by. Equipment. At the moment, my FC 3000 is hard working but she'll be free in 7 days and will be added to these grows. For the moment I'm using a viparspectra at 45cm at 65% intensity. Using Green House Feeding for nutrients, biobizz light mix & all mix. For the moment they only on light mix but on the uppot in 7 or so days I'll add some All Mix. Every 2 weeks I'll add 1g/1L of Bioenhancer, and that's it. Real easy, will give me more time to work on the girls as they grow and not worry about what needs what, just water and go, depending I get the mixes right. Week 1, seedling day 3. All the girls done in Rock Wool showed roots down the end of the wool, all but 2, I could see in the hole that she was strangling herself, I carefully cut the wool in half, still no roots, so, I went in, and I'm glad I did. As you can see, she literally cut her own roots, it was dangling and came off with ease. Using gloves I held the stem over the 3/4 full wet pot of substrate. Made a small hole in the middle and placed the roots in it and held the stem and folded the dry soil around the stem making it secure. Now, there's no need to wet the top, (as the roots were in the base I made that was wet, so there is no wet soil around the stem. (I'm only thinking of it now, I have clonex gel that would of rapidly increased root growth and helped take some risk out of her not been able to make it) After a few days when I know she's out of danger I'll spray the top of the substrate to activate the nutrients and hopefully get some good mycelium/fungus going. I had a feeling this would happen, it happens a lot in soil but we don't notice it, and if I was using synthetic nutrients she more then likely would of grown out of the rock wool but as the roots need to be touching the soil as that's where the nutrients are it would of struggled. So needed to be done. Next few days will be do or die for this gal. She was stressed a lot and lost half of her tap. Let's see.(update below) Seedling D 3 was when she was uprooted from Rock wool and transplanted with cut roots, D5 you can see her, 1 of her cotyledons has turned pale, so she did struggle to find her footing, but she is doing well. The other WatermZXVelvet moon that was was done with rockwool is in much better shape, have a look. The nutrients are mixed into the soil and you just water every time she needs it, the bioenhacer needs to be given once every 2 weeks. I mixed 3g/1L of substrate. As she gets older when I uppot her I'll add extra powder per/L of sub and I'll also be introducing some biobizz all mix. I just want to get going on some good fungus action and if I added some all mix I wouldn't of been able to add enough powder to get mycelium/fungus going, this is healthy and good. You'll see it when you use root stims, it'll make stuff fuzzy, mycelium. Good fungus that will decay with organic matter and make for a good bacteria ground for your gals. Seedling Day 5 We have fungus lift off, she out of the woods after Harsh transplant if you haven't read about above. Seedling Day 5-7 Okay steady normal growth. I can just see the next set of nodes to up come. So she's on track for normal growth. Her sister though, is miles ahead. 2moro is a new week, so now that the RH/TEMPERATURE is dialed in I'm hoping I'll see explosive growth. Thanks to my sponsor at Green House Seeds who I death with, great guy. And to everyone there that makes these great strains. And to my sponsor who sought me out from marshydro, she's a pleasure deal with, love this brand. COUPON FOR MARSHYDRO Use code GGS at any marshydro site for a discount.

6/17: I am keeping things as is for the time being. The light is 20 inches from the plant at 350 PPFD on a 24 hour light schedule. Growth seems to be constant and picking up steam with tighter inter-nodal spacing at these settings. I plan to switch from the seedling light spectrum to a vegetative light spectrum once the second set of true leaves gets a bit more of its form. I will also change the light schedule from 24hr to 20/4. 6/19: Today marks the first day of the 20/4 light schedule using a vegetative light spectrum. All other conditions are the same. I'm still only spraying the soil once a day but feel by next week, I can up the feeding with a little calmag. We will see! 6/22: End of week two and things are looking great. I'm still a newb but I can see improvement in my strategy this grow. The plant is growing nicely and seems to be on a good pace. 6/21, I added in some calmag and upped the feeding amount. I also bumped my lighting up a bit too. I saw quick results as seen in the timelapse that day, as the leaves started to pray up. As of Sunday, all is well and so far this grow is exceeding my expectations! WEEK 2 AVG TEMP: 72.6F WEEK 2 AVG HUMIDITY: 74.3%

Week 6 of flowering 10/23/24 Changed nutrients to fit week 6 Buds are getting even bigger and thicker. Defoliated a little. Noticed a PH of 4.8 in runoff, same as the late stage of flower in my previous grow. After lowering feed EC, CalMag on max strength, flushing with 0.8ec nutes for 3 days in a row, nothing changed and PH stayed the same. Read in a forum thread about constant low PH in the rootzone when growing in coco. Got great info about CEC, water, nutrients and little chemistry from a detailed explanation. (https://www.icmag.com/threads/recurring-problem-with-low-ph-in-coco.338385/page-2#post-10843765) Flushed plants with tap water + calmag, PH 6.5. Used 120L total for 4 plants in 2 days. 1st day: flushed after lights on, did not water until 2 hours before lights off and flushed again. Runoff PH went up a little, but not to the correct range. 2nd day: flushed after lights on and checked runoff EC + PH, of each plant. Fortunately, PH got corrected to 5.8, and I returned to automatic watering 4 times a day (with 10%-20% runoff). Thoughts: In the last grow, I thought I had a problem because of salts buildup in the media with constantly low PH in late flower. I didn't fully correct the problem till chop day. Same problem here in the same stage of flower without the salt buildup. After reading every forum I could find about the problem, I understood that my bloom nutes were the main problem because of their chemical composition. The coco ability to exchange ions lead to the low PH in the rootzone. It got worse quickly because I did not use any tap water with the feedings, so the PH could swing easily and drastically without resistance. After I looked online for the T.A. feeding chart, I saw they used TriPart Grow till week 7 of flower, the Nitrogen type they are using will up the PH. CocoForCannabis chart that I'm using, has not enough nitrogen to combat the bloom nutes PH down effect in flower. It gets even worse with RO water because there are no minerals that can resist PH down. Now I'm using 30% tap water with rest RO water, T.A. TriPart feeding chart with calmag and silica. Hopefully I have corrected the problem for the rest of the grow. It wasn't easy, because there were lots of variables that worsened the problem quickly. Now I'm checking runoff PH and EC daily. Update on next week :)
