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. 🌱💚

Its showing the potential they got

Filled in nicely after all cropping was done.Mostly the bottom and midsection show great development. I've had them on a 16 hr schedule for a few weeks I think I'll flip the lights to 13/11 tonight. Trying something different in lowering the daylight time gradually to a final end of flowering light/dark of 10/14.

After 1 week of growing, the Blue Dream'Matic is doing well. I am going to slowly increase its nutrient solution strength and lower the lights to dial in some stronger growing conditions. It has been enjoying 1-2 times a day fertigation so I think the coco medium is draining well. I have included a time lapse of the first week of growth. I am working out the kinks of the setup, so the video is a bit messed up towards the end, but it shows potential that I am going to keep working on! Day 8: transplanted to a larger pot as a significant number of roots were growing out of the seedling bag. Day 9: It looks like there has been a cal-mag or root issue affecting the first set of leaves, which grew in while there was a lower nutrient EC. The new growth has not been showing the same issue, so hopefully the issue has been resolved. Thanks for reading, and happy growing!

Im so loving this strain ! Smells so goooood!! Did a last watering with Dense by GP Im really loving this stuff!! Check my IG account for a giveaway @Frosty905budz The flushing has begun Flushing with Flawless finish by Advanced nutrients [email protected]

Holy growth! All these ladies grew exponentially since my last entry. I even left them for a weekend without any issues. This week I decided to start on my second round of nutrients by including Fox Farm Grow Big. I also added an Exhale Co2 bag for additional growth support. Will have an update next week. Thanks for viewing! -H

Have been flushing the past 2 weeks hence the yellow and purple leaves. Chopping her down right after this photo shoot. Probably get 14-20 grams dry, but not bad for a solo cup auto with pretty quality buds. Stem has been green the whole time— so she’s healthy. The smell is an earthy pine cone. Easy peezy with dynomyco! ✌️💚🌿💨

Wee maDe it through another week. Day by day night by night joint by joint.

The plants are done stretching. They did stretch a lot and grew very quick. As soon as I open my tent, my whole room is smelling. And I can tell you it just smells 🔥🔥🔥🌴🍪⛽️🌲. The small pheno that is producing purple buds smells like I expected the Tropicana Cookies, 🍊🌴⛽️🌲. The other 2 smell more 🍦⛽️🌲 and not fruity at all at the moment. In overall my plants are very healthy and they seem to feel very comfortable in my tent✌️

wet trim, nice buds, will update when more details are available --- got 0.3g of crazy scissors hash - vaped a tiny bit of it and the high is amazing 🤩 ---- 11/6/20 started curing & made some RSO of the trimming (~3ml) ---- 11/7/20 made a 2nd batch of RSO (~10ml)

Hey everyone! So this week has been fairly straight forward and noticed some deficiency of calcium / magnesium that i'm in the midst of either a) do I treat it with 4 weeks left of flowering or b) do I make sure to add in kelp meal into my next grow for autonomous feeding, allow the plant to uptake on it's own. Going to go with option b since I noticed on my cream caramel grow, this deficiency was starting to show in early veg and thought nothing of it. With this being shown so late in the flowering, i'm thinking she is sucking up all the leftover nutrients before "dying off" and budding. The tent is holy stinky, i'm glad the carbon filter is doing it's job but I tell ya, watering is such a delight :) Buds are getting larger by the day..sweet skunky smell :) I count on one stock over 30 flower's that seem to be about toonie size, maybe larger, but get fatter by the day. This strain might be one to keep in the books to grow again :) Bye for now guys!

starting to smell like a winner!

Girls keep growing pretty well in my rookie opinion, giving them a lot of time and love ❤️!!

So far it seems to be fine even if the high humidity worries me even if the temperatures are still high then they have stopped growing and will finally focus on the flowers and slowly we recover these small deficiencies

Veg week 2 Day 36 from seed Topped 11/17/23 LST coming up Microbial tea end of week

Timelapse Days 21-34: Memory card filled up and I lost days 35 and part of 36. Day 36: No photograph. No longer centered under the light. I need more lighting. Day 37: plant taking to the training well. Almost time for another tent peg. Day 38: Still growing. Day 39: Worried this is mold. Added a gallon of water with nutrients increasing the nutrients to mid-vegetation. Overall I think the plant looks pretty healthy. Day 40: Turned the carbon filter on to promote air exchange. Day 41: Continued training. Day 41: Rushing the exhaust fan has reduced the humidity. Going to have to keep an eye on that.

Week 6

day22 video. now adding more pk booster than earlier weeks, should be done week 7-8 we will see day23 I start adding more pk, still will 4x more pk now. Some nice pics today, videos of each, frost on fan leafs, no issues other than pros: bridal frost on fan leafs+sugar, cons 6ft tall. I think I should have pumped more pk earlier into flower/pre Its cool. Adding 2tbsp soluble pk into 5gal vs quarter tbsp in beginning 22 days ago. I am feeding soluble pk, +3 pk soil conditioners and carbs every day. There is no water day. day 25 stacking up. been spraying old cs I made 3ish years ago to test, works on unrooted so I may potential cross. Bridal starting to smell like a mix between fresh watermelon, and lemon+lime or a citrus aroma.
