Cash Express – Pheno A | Week 4 Full Steam Ahead Welcome back to another chapter of the 8×8 Adventure, where twelve cultivars are being documented individually from seed to harvest under a strict 12/12-from-seed schedule. Every phenotype follows its own diary, allowing each plant to reveal its unique personality while growing under exactly the same environment and feeding program. Another week has passed, and the room continues to transform at an incredible pace. What started as twelve tiny seedlings is rapidly becoming a forest filled with individual characters, each responding differently despite sharing identical conditions. That’s one of my favourite parts of this project—watching genetics tell their own stories. This week also reminded me that Mother Nature has a funny sense of humour. The environmental controller proudly displayed 33.3°C alongside 63% humidity. Apparently the grow room has decided that three is the lucky number this week. Despite the higher temperatures, the elevated humidity helped keep the plants comfortable, and growth across the room never missed a beat. Every day the canopy became denser, greener, and noticeably more alive. ⸻ Week 4 Environment 🌡️ Temperature: 33.3°C 💧 Relative Humidity: 63% 💡 PPFD: 700–800 µmol/m²/s 🌱 Medium: Plagron Lightmix ? Growing Method: 12/12 From Seed One interesting change this week wasn’t caused by the lights—it was caused by the plants themselves. Some phenotypes have entered a much stronger vertical growth phase, naturally moving closer to the fixtures. Those taller individuals are now receiving around 800 PPFD, while shorter plants remain closer to 700 PPFD. The light hasn’t changed. The plants have. Watching each phenotype respond differently under identical conditions continues to be one of the most fascinating parts of this entire project. ⸻ Feeding Strategy The nutrition program has continued to evolve alongside the increasing demands of the garden. During the establishment phase, irrigation remained around pH 5.8, creating ideal conditions for vigorous root development. As those root systems expanded throughout the containers, the nutrient solution gradually shifted toward pH 6.1, allowing access to a broader spectrum of available nutrients within the substrate. At the same time, nutrient concentration was increased progressively throughout the week, finishing around EC 1.8. Nothing dramatic. No aggressive jumps. Simply allowing the plants to dictate the pace rather than forcing one. Healthy roots create healthy plants, and the steady growth throughout the room suggests they’re very happy with the direction we’re taking. ⸻ Cash Express – Pheno A If this lady had a motto, it would probably be: “Catch me if you can.” From the beginning she’s shown an incredible desire to grow, and this week that enthusiasm became even more obvious. While several of the other phenotypes are still building compact structures, Pheno A has decided she’s in a hurry. She’s stretching confidently toward the light while simultaneously producing an impressive amount of lateral growth, creating a plant that feels both elegant and powerful. What has impressed me most isn’t simply her height. It’s how well she’s responding to every bit of training. Throughout the week I’ve continued gently tucking leaves and applying light stress training wherever needed to open the canopy. Rather than slowing down, she seems to reward every adjustment by pushing even more vigorous side branches toward the light. It’s exactly the kind of response every grower hopes for. Each newly exposed branch immediately begins reaching upward, gradually transforming the plant into a much more balanced structure with multiple future flowering sites. The internodal spacing remains very attractive—open enough to allow airflow and light penetration, yet close enough to promise dense flower development later on. Her main stem has thickened noticeably over the past week, giving her a sturdy backbone that’s clearly preparing for the stretch that’s still to come. The foliage is lush, healthy, and beautifully coloured, while the fresh lime-green growth emerging at every tip is a constant reminder of just how actively she’s developing. Looking at her now, it’s easy to understand why this cultivar carries the name Cash Express. She certainly isn’t wasting any time. Every day she seems determined to be just a little taller, a little fuller, and a little stronger than she was the day before. ⸻ Looking Ahead Week 5 should become even more exciting. With flowering now beginning to establish itself, I’m expecting the stretch to continue while the first real flower formation starts becoming visible throughout the canopy. Over the coming days I’ll be watching closely for: • Continued vertical stretch. • Development of the trained side branches. • Early flower site formation. • Structural balance after continued LST. • How she compares to her sister phenotype as flowering progresses. If this week’s momentum is anything to judge by, she’s only just getting started. ⸻ Thank You A huge thank you to everyone following this 8×8 Adventure and joining me each week as these incredible genetics continue their journey. Thank you to the amazing GrowDiaries community for providing a place where growers from all around the world can learn from one another, share experiences, and celebrate this incredible hobby together. A special thank you to Plagron for supplying the nutrition and cultivation support behind this entire project. Thank you to Zamnesia for the outstanding genetics, equipment, and the opportunity to document every phenotype from seed to harvest. And finally, thank you to everyone who stops by, leaves a comment, shares advice, or simply enjoys watching these plants develop into their own unique personalities. Every phenotype follows the same path. None of them walk it the same way. Growers Love, and I’ll see you all next week. 🌱💚

Finally got myself a dehumidifier, now i can controll the humidity in my room because it often went above 60% 🤷‍♂️🏻 Also love how the big northern light is really packing some weight! & the buds on the bottom look as good as the ones more on top!! Can’t wait till i can harvest all of em😁

Oramai non riesco a metterle più nella grow se non incanstradole una nell'altra. Questo comporta che le piante prendono luce solo sopra, sto cercando di ovviare al problema mettendole al sole ogni volta che posso. Oggi 52 giorni dalla semina è il 6 marzo 2021.

Not bad for a one gallon and rain water. Frosty, smells amazing and will be harvesting in a day. She was faster than the diary says because of the memes. 🏻💚

Disappointed with the over all yeild but happy with the quality of this strain over all a good solid strain

One of them is showing calcium deficiency but I will add some calmag from Biobizz and hope it will solve the problem. I live in a very humid area and its raining all the time so it's very hard to maintain a low humidity level. I follow a VPD table (vapor pressure deficit) and with the 25º C and 55% RH its a good indicator for flower. Feel free to ask anything! :D

💚 ORION LIQUID NUTRIENTS 💜 This is a clear example of me absolutely underestimating the nutrient need when using only liquid nutrients. The plant, as a result, has really not grown as this in comparison with the 💚ORION F1 ORGANIC DRY AMENDMENTS* 💚 Which has been topped and grown 3 times the size of this one! I topped this plant on the 20.6.25. Here is what I fed this week: 19.6.25: I watered with 2L of dechlorinated water PH'd to 6.1 and containing the following nutrients per 2 litres; ♡ 1/3 Cal-Mag ♡ 1/3 Mega Crop Part B ♡ 1/3 Tsp Mega Crop Part A by Greenleaf Nutrients PH: 6.1 PPM: 891 26.6.25 I gave 2ltrs of dechlorinated water PH'd to 6.6 with the following nutrients per 2ltrs; ♡ 2 ml Ecothrive Trace ♡ 1 Tsp Ecothrive Biosys PPM: 811 PH: 6.6 Thanks for stopping by this week 💚✌️🍃😊🌱

Started ripen, last 2 weeks now

🍀14/12 - Empieza su primera semana en etapa de floración. 🍀Se encuentra perfecta y hasta el momento no tuve ningún problema con ella. 🍀Tiene una altura de 77cm de largo, crecio mucho en poco tiempo y se ve que va a estar muy buena. 🍀Hoy cumple 41 dias de vida desde su germinacion. 🍀En estos dias estare subiendo mas imagenes. 😶‍🌫️🇦🇷🍀Podes seguirme en Instagram como @BruWeed_arg🇦🇷😶‍🌫️🍀

This was my first cycle in tent. The Autopot System is amazing ang brings autonomy. I used fert Plantprod, calcium nitrate, magnesium sulfate and MKP. PH around 6.0 and solution fert in tank 1200 PPM . This strain is fantastic. It withstood the intense heat of the southern hemisphere's tropical climate. It was easy to prune and defoliate to control the size. The smell is of tangerine and flowers produces a lot of resin. I am very satisfied with this harvest! Thank you Sweet-seeds!!

April 26, 2024 Day 71 It's a new week and the start of late flower. It was also cleaning day. Both reservoirs have been cleaned out and are freshly loaded with new water. This week we are focusing on watering and nutrients. I may start to drop the dose until flush, over this week and the next. The light power will also be gradually dropped down over the next 2 weeks. Not much this week, I think I'll drop the DLI down to 43 mol/m²/d in the middle of the week. Next week I'll drop it down to 38 mol/m²/d. It all depends on what the plants look like. The plants are getting ready to hunker down and finish up. Both have decent sized buds and just need to finish swelling. I'd say another 2 weeks maybe? Flushing will start at some point over the next 2 weeks as well. Flushing won't be much of a big deal as it's just cleaning the reservoirs and running a week of Flawless Finish. The environment is changing a bit as well. I dropped the day temp down to 75° and the night temps to 65° or lower. Not cold enough to cause stress, but enough to get some purple I hope. The humidity is sitting at 47% and I'll be leaving it there unless somehow I can get it to go lower. For now it's pretty solid at 47% and everything looks great, so no need to worry. I'll be taking trichome pics every few days. One pic for each plant. No point in loading up the whole photo gallery with even more daily pics. Plus, the progression of trichomes isn't fast enough to really notice daily. So every 3 days should be fine. Grow System Environment: Temp: 74.2° RH: 47.7% VPD: 1.49 kPa April 27, 2024 Nothing happening today. Both ladies were inspected with no issues. I snipped a single leaf off of Banana Purple Punch B. Just one. Blocking bud sites. Banana Purple Punch A has some massive buds. About the size of golf balls. Maybe a bit smaller. They are still swelling and have a good 2 weeks left. Pistils are still mostly white, so that's a good sign for larger buds and more trichomes. Banana Purple Punch B is looking wonderful as ever. She doesn't seem to be suffering any issues with nutrient burn unlike her sister plant. She's perfectly healthy and has very nice bud production. The buds aren't quite as big as Banana Purple Punch A, but still nice and sizeable. The nutrient burn seems to have stopped for Banana Purple Punch A. So that's good. It should be perfectly fine now. Lighting is staying the same for the next couple of days. Although, I may keep it the same for the rest of the week. The environment is excellent now. It's raining today and the humidity is still at 47%. I did get it down to 44% for most of the afternoon yesterday, so I may be able to keep it down after the rain stops. Or just wait for the afternoon and see what happens. Either way, the humidity is now at 47% and the temp is at 76.8°. The VPD is at 1.57 kPa. A tiny bit high, but still well within range. Last night's temp was a little high at 69°. I'll have to drop the temp lower again to get that 65° sweet spot. Grow System Environment: Temp: 74.4° RH: 45.7% VPD: 1.55 kPa April 28, 2024 Not much to do today. I mixed a new batch of nutrients for both plants. The only difference is that I cut the Overdrive in half down to 2 ml/gal. Neither plant needs it, but now it's mixed and ready to go. I may end up filling the reservoirs tonight as it stands. Or later this afternoon. I don't think they will last til tomorrow morning. Both plants are putting off a wonderful aroma. I honestly can't describe it. Like sweet and kind of a hint of banana and a bit heady. Trichome production is picking up quickly. The pistils are starting to turn orange as well. They are definitely in the late flowering stage. I think I'll start dropping the nutrients for the next watering. And I'll drop the DLI down to 40 mol/m²/d tomorrow I think. Not much else to say about nutrients or lighting, so moving on to the environment. It's a warm humid day out and raining off and on. My whole environment is wonky, with humidity being at 57% and the temp at 77°. I turned the AC on about an hour ago and the temp went down to 75°, and humidity up to 60%. I think I'll crank the AC all the way down. And hopefully get rid of the humidity with the temp being a bit lower than perfect. Update: I ended up adding about a half gallon of plain water to both reservoirs. Just Incase I have nutrient lockout or something. They should go through that by tomorrow afternoon. Maybe late evening. Grow System Environment: Temp: 75.6° RH: 52.8% VPD: 1.39 kPa April 29, 2024 No watering today. I'm still waiting for the plain water work it's way through. However, I did drop the light power. Both ladies look great. Big buds, great scent and nice color. I'm not seeing any fade yet, but the nutrient burn is still there. I hope it will fix itself with the plain water. And then maybe fading will start. These two need a good 2 weeks or so before harvest. The lighting, as I said, was changed today. I dropped the power down to 70% to get as close as possible to 40 mol/m²/d. I may have to drop it another 10%. I'm not too sure. I'll check the DLI again when I'm more awake. (I'm finally on my second cup of coffee. Lol) Looks good though. Just around where I want it to be. But there are a lot of spots where the DLI is a bit high at 43 mol/m²/d. The tallest tops are also kind of high at 45 mol/m²/d. Again, I'll double check on a couple hours, but it should be fine. The environment is wonky again today. The temp is fine, but the humidity is still high at 60% and I don't see a way to drop it again. Not with the current weather. Hopefully I can get it down with some heat. The AC method did not work. Well, it maybe will work tonight. I'll be dropping that bad boy down to 59° tonight and hopefully it will do what I need it to. Grow System Environment: Temp: 74.2° RH: 59.8% VPD: 1.15 kPa April 30, 2024 Watering day. The reservoirs were both nearly empty and there was just enough space for a full gallon in each one. It's the normal nutrient dose with Overdrive being at 2 ml/gal. These two plants are looking mighty fine. Excellent bud swelling and trichome production. I'm definitely going to be wet trimming them instead of my normal dry trim. I may leave the bods on the branches and do a partial wet trim, or I guess mostly wet trim. They smell great! Very strong aroma now. I swear they smell like artificial grape. I can't describe it any other way. Grape and pungent. Awesome. So far the light seems to be fine. No reaching or showing any signs of lack of lighting. They look pretty happy. Although, Banana Purple Punch A is a bit sad from nutrient burn. Banana Purple Punch B however didn't seem to have much of a problem with the burn. The environment is still pretty wonky. High humidity again. I can control the temp pretty easily, but the humidity is another issue. It's currently sitting at 56% and I'm holding the temp at 76°. Grow System Environment: Temp: 75.5° RH: 57.0% VPD: 1.26 kPa May 1, 2024 Not a whole lot going on today. No water needed, no light changes. I rotated both ladies 180° so now they are getting light on other sides. I'll leave them like this for the rest of the grow I think. Banana Purple Punch A actually fits better in the new position. Less wall touching and about the same neighboring plant touching. I also removed 3 leaves. Ones that were misshapen from being crushed against the tent walls. Banana Purple Punch B seems to fit a little better in the new position, mostly because of her sister plant. More room on the outside and a little less room inside. No leaves were removed today. I'll reserve that for the last 2 days of the grow cycle. Then I'll do a massive defoliation and then a wet trim. It's humid here right now and I need the space. Otherwise I'd stick with dry trimming. But I can't hold up the tent for 3 more weeks. I have other plants getting ready to be planted in their final containers. Like a week for that, I might be able to squeeze a week and a half, but that's it. They will have a space, but the main tent is where they will need to be. Not a 2x2 dry tent. I'll work it how I need to I guess. Anyway, both ladies look great! Trichome production is coming along nicely as well. They are very smelly now and I love it. They are also still packing on weight I think. Not a ton, but the buds are clearly getting denser now that some of the pistils are starting to turn orange. I'd say another 2 weeks on these two. As I said, the lighting hasn't changed at all. Not for another few days to a week. Then it will have another power drop. Until then, we are staying at a DLI of 40 mol/m²/d. It's roughly 38 mol/m²/d on the outer part of the canopy. The environment is STILL wonky. I cannot for the life of me get that damned humidity down at all. Not with a dehumidifier, not with the heat cranked, not with the AC cranked. I'll try my big dehumidifier in my room, but the humidity is like 49% and frankly I'd rather the room humidity stay there. Much easier to breathe. However, the humidity in the tent is suffering at 59% while the temp is hanging out still at 76° Grow System Environment: Temp: 75.2° RH: 56.1% VPD: 1.27 kPa May 2, 2024 Not a lot going on today. No watering needed, no trimming, nothing. I found a broken bud on Banana Purple Punch A. It must have been from when it was against the wall, or too close to the other plants and got stuck on a branch while I was rotating. Oh well. It's a lower bud, so not huge. It's also the last day of the week and that means new videos! For the rest of the grow, I'll be making weekly videos of the individual plants. So that will.be this week and the next 2 weeks or so. Banana Purple Punch A looks great aside from that one broken bud. Her buds are fat and thick. Super dense from what I can see. I would like to note that the fade hasn't started yet, so we still have that 2 weeks left. Unless it starts in the next day or 2, I'll be banking on 2 weeks. Banana Purple Punch B is still compact as ever, but her buds are getting fatter everyday and of all the plants in the tent, she has done the best with the nutrients. Very little burn and didn't seem to be bothered by it. Maybe I did something early on to have such a small plant, but still. I think I can bank on 2 oz from each plant. Maybe 3 oz. It's really nothing compared to previous grows, but as I said before, as long as it's fire, I'm happy. Trichome production on both plants is fantastic. They are loaded from top to bottom. And building more and more everyday. There's still plenty of time left for there 2 as well. Most of the trichomes are clear with about 20% being cloudy and sparsely amber. That's another sign that they need another couple of weeks. Maybe slightly less. I increased the light power yesterday back up to 80%. I think I was a bit early on the intensity drop, so I'll drop it again in a few days I think. Around mid week coming up. Now we are running a DLI of 43 mol/m²/d inside and 40 mol/m²/d on the outside. The environment kinda fixed itself, but not to the ideal climate. It's still at 55% humidity. Better than 60%, but still not good enough. It needs to be below 50%. However, I can still control the temp and I have it at 74.5°. I'll turn it up a bit and see if I can clear out the last 5% of the humidity. Grow System Environment: Temp: 73.7° RH: 55.2% VPD: 1.24 kPa Update: I added a couple test videos to see if they would upload. Success!

Cruising right along. This is technically day 6 of week one and they are performing as I had hoped they would. Already splitting off and I upped my nutes to try and get as much as I can in the vegetative weeks as possible. I know it’s pushing it but no guts no glory as I’m running 1064ppm. Added some photos from day 10. What a change.

Hopefully only two more weeks to let her flower. Keeping an eye out for the color change. Everything seems to be bulking up as we speak.

Can't tell I was happy with the outcome but I think this is more a indoor type.lots of problems with bugs and to hot weather.they did not Heald as fast as other autos..but still can't wait to smoke..

The pistils are still white Shes very fat now and i think 2 weeks before harvest, i feed less now at 400ppm and starting ripen feed when half of her pustils turned brown August 18 (mid this week) I flushed her completely and fed ripen untill runoff got in the 200ppm. Now she is ready to finish Harvest will be at august 28th

Finally all got rid of their little hats and are looking healthy. TD 3(drooping cotyledon) needed a bit of help so I removed the seed shell with tweezers. Note: The Mycotrex is listed as nutrient because it resides around the shell and than again 10cm below it. 2020-11-12: 1l nutrient solution with 0.5ml of Bia Canna Vega since the soil is Light Mix without any nutrition. I also lowered the light since they were stretching a bit. Light at 25% intensity. 2020-11-14: 300ml ph adjusted water each 2020-11-15: Raised light intensity to 50% 2020-11-17: 300ml ph adjusted water each TD1: 7cm TD2: 5.5cm TD3: 7cm
