Runtz — 🏆 Eternity Grow Cup 2025 🏆

ATLien415 📆 WEEK 1 🌱 Plants: Roots are visible and into the aeroponic cloner they go! 💧 Hydroponics: I mixed in two gallons of Heavy 16 Seedling and finished it off with 4 mL of Green Sensation into the two gallons of water. After that first 4 mL, I was happy with where the water was at for the seedlings. The goal here isn’t to push them but rather to get the girls familiar with the blend. From what I’ve read, Green Sensation really starts to shine following pre-flower.

ATLien415 📆 WEEK 2 💧 Hydroponics: They’re mostly just pulling water right now, and with a solution change coming up next week, I left the mix alone today.

ATLien415 📆 WEEK 3 💧 Hydroponics: Swapped the solution today with one gallon of Heavy 16 Veg Week 1 and 8 mL of Green Sensation to finish dialing in the two gallons of water. ⏳ Timeline & Outlook: The girls will be making the move from the aeroponic cloner to their RDWC flowering homes sometime this week.

ATLien415 📆 WEEK 4 🌱 Plants: Transplant happened on 1/20. 💧 Hydroponics: This round included four gallons of Heavy 16 Veg Week 1, 32 mL of Green Sensation, and 5 mL of pH down to finish amending roughly 10 gallons of water. On 1/24, I added another 8 mL of Green Sensation and 5 mL of pH down to keep things dialed in. ⚙️ Equipment: Deep clean of the RDWC and preparation for the girls.

ATLien415 📆 WEEK 5 🌱 Plants: Took a cutting from the girl on the far right - she’s showing stronger root development and a deeper green compared to the rest, even with all variables held steady across the board. 💧 Hydroponics: Topped off the solution today - used three gallons of Heavy 16 Flower Week 1 and 12 mL of Green Sensation to finish amending the ~10 gallons of water. ⏳ Timeline & Outlook: They are due for a trim in the next few days, and then it's a fresh solution and the flip to flower next week.

ATLien415 📆 WEEK 6 💧 Hydroponics: Full solution swap today - four gallons of Heavy 16 Flower Week 1 and 12 mL of Green Sensation went in to amend the ~10 gallons of water. ⏳ Timeline & Outlook: Flipped on 2/7. Planning to let them ease into the netting on their own, with a major defoliation coming up in about three weeks. Letting them settle in before the big clean-up.

ATLien415 📆 WEEK 7 💧 Hydroponics: Topped off the solution and amended with four gallons of Heavy 16 Flower Week 2, 12 mL of Green Sensation, and 5 mL of pH down. ⏳ Timeline & Outlook: We’re sitting about two weeks out from the major defoliation - just letting them stretch and fill the net naturally in the meantime.

ATLien415 📆 WEEK 8 💧 Hydroponics: Full solution swap today - amended with four gallons of Heavy 16 Flower Week 3 and 12 mL of Green Sensation. ⏳ Timeline & Outlook: We’re about a week out from the major defoliation. Starting next week, I’ll begin ramping up the Green Sensation while tapering off the Heavy 16 additives and boosters, following what I’ve gathered from the use guidelines. Lights will also get bumped up and adjusted to match the average canopy height as we wrap up pre-flower.

ATLien415 📆 WEEK 9 Green Sensation has been a pleasure so far. The girls are clearly vibing with it - honestly, the pre-defoliation bushiness was getting mildly overwhelming. My only hesitation is stepping away from my usual additives/boosters. I’ve always adjusted my routine on the fly, but if these girls start to push back, I’ll be in unfamiliar territory. Also worth noting that the seeds from Zamnesia are showing some real promise. The foliage already carries a subtle sweetness, hinting at the profile that’s starting to peek through. 🌱 Plants: Major defoliation went down on 2/28. I’ll be mulching the trimmings into the soil that’s prepped for a tomato planter this Spring - closing the loop a bit. Canopy is basically locked in now, and I’m good with how it shaped up. Each plant's main cola is riding slightly above the canopy, but that’s par for the course when I stretch them into flower — standard tent behavior over here. 💧 Hydroponics: Full solution swap today - amended with four gallons of Heavy 16 Flower Week 4 (left out Prime and Fire) and 32 mL of Green Sensation.

ATLien415 📆 WEEK 10 🌱 Plants: I don’t usually deal with burning in hydro, especially compared to my soil days. But these girls are massive now, with huge root systems that are taking up a ton of space in the flowering sites. This is effectively reducing the overall system volume for nutrient solution by a pretty substantial amount. On top of that, they’re thirsty girls, so the swings in solution levels due to water uptake are becoming noticeable. I might turn the lights down a bit to slow the water uptake down, because if I don’t, I’m looking at a high burn risk in the next few weeks. 💧 Hydroponics: Full solution swap today: 4 mL Heavy 16 Roots, 10 mL Heavy 16 Finish, 30 mL Heavy 16 Bud A, 30 mL Heavy 16 Bud B, 40 mL Green Sensation, and about 20 mL of pH down to amend the solution. ⏳ Timeline & Outlook: The plan is to leave the canopy as it is for about two more weeks. After that, I’ll do some serious lollipopping and start a two-week nutrient sunset/flush routine (though I may end up pushing the flush back a week depending on how things go).

ATLien415 📆 WEEK 11 🌱 Plants: My middle girl went through a bit of stress when I didn’t tend to the solution daily. With such tight margins, this led to a 12-hour stretch of the solution being in an acceptable range, but just acidic enough to mess with a few one-off nutrients. Unfortunately, this meant a flush mid-flower - if it happened in a week or two, I would’ve let it ride, but it had to be sorted now. Found an intersex site on one of my girls - not ideal, but part of the process growing modern exotic hybrids indoors and pushing them in my opinion. 💧 Hydroponics: The tap water here’s been running hot due to acid rain, which was a pain earlier in the week but has actually been fantastic lately, coming in at a steady 6.5 - pretty ideal now, but definitely a struggle at first. Full solution swap today: water’s at 6.5, added 20 mL Plagron Green Sensation and 2 gallons of Heavy 16 Flower Week 5. ⚙️ Equipment: I’ve had a slight shift in my understanding of the Plagron Green Sensation instructions. Initially, I thought it was just a supplement/booster replacement, but now I realize it actually covers the base nutrients too. So after the flush, I amended the solution with this new understanding. ⏳ Timeline & Outlook: I’m still pretty excited about this crop as the girls are showing off a tropical, rotten-lemon-heavy sweetness at the flower sites, which is exactly the vibe I’ve been hoping for. I plan to lollipop the plants on 3/21, then sunset the nutrients with the last feeding on 3/28. I’ll start the flush on 4/7 and aim to harvest somewhere between 4/14 and 4/21.

ATLien415 📆 WEEK 12 🌱 Plants: The girls got their lollipop treatment today to improve light penetration into the canopy, now that the bud sites are entering their final development phase. Overall, the two girls on the left (the more sativa-leaning phenos) are light feeders who don’t handle much stress from training or trimming, which isn’t really my style. The girl on the far right (the more indica-leaning pheno) is a heavy feeder but doesn't tolerate high light intensity, which also isn't my preferred approach. Because of this, I’ve decided to cull my runtz mother clone of the indica pheno - trying to keep all three girls at their best in the same environment just feels like a fool’s errand. 💧 Hydroponics: Full solution swap today - water is at 6.5, with 24 mL of Plagron Green Sensation and 2 gallons of Heavy 16 Flower Week 6ish to amend the solution. ⏳ Timeline & Outlook: The new plan is to sunset the nutrients and lollipop the plants on 3/21, begin the flush on 3/28, and target harvest on 4/14.

ATLien415 📆 WEEK 13 🌱 Plants: The indica-looking pheno (the one on the far right) has a sweet kushy smell. The middle plant has the classic RuntZ aroma, and the plant on the far left has a distinct Gelato smell. Honestly, I wish I’d kept a clone of the one on the left instead of the indica-leaning one, but that’s just how it goes - I chose the one with better root growth, and how that’s translating to buds and flavor will be revealed soon. The one on the far left smells like a clean Dairy Queen cooler, flat Z terps, just a really clean scent. It’s wild that they all started with a rotten-lemon smell and evolved into such different profiles. Typical F1 generation behavior. 💧 Hydroponics: Full solution swap today: water came in at 6.6 pH and (yikes) 0.4 EC. Added 5 mL pH down and 8 gallons of Heavy 16 Flush Week to the 8 gallons of water (this is the one time I stick to the manufacturer schedule). Enviornment: Lights are all the way up; the tent thrives best when I can manually breathe it, otherwise it starts messing with its own humidity and CO2 levels. ⚙️ Equipment: I temporarily lost access to my online drive with the feeding schedule spreadsheet, which is way easier to digest than manually calculating feed per gallon and how many gallons I actually used (since I never feed full-strength manufacturer nutrients). This week was simple though - the buds are deep into swell, so I’ve started flushing. ⏳ Timeline & Outlook: The flush will be swapped for pure water sometime this week while the tent’s lights are OFF, which I think is a critical step. If we’re still pulling salts after the pure water flush, I’ll swap it out for fresh water based on the nighttime readings. On 4/4, I’ll swap the solution to water only at night. Then on 4/7, I’ll swap the water flush for a fresh water flush at night. The target harvest date is 4/14, depending on how the flush is going and how the foliage burn is progressing, though this could shift by a few days.

ATLien415 📆 WEEK 14 💧 Hydroponics: Full solution swap today: added 5 mL pH down and 7 gallons of Heavy 16 Flush Week to 7 gallons of water (this is the only time I stay on schedule with the manufacturer). Enviornment: Lights are set to 70%. ⏳ Timeline & Outlook: On 4/7, I’ll swap the solution to water only at night, then on 4/9, I’ll swap the water flush for a fresh water flush at night, with the target harvest date set for 4/11, marking a 63-day flower.

ATLien415 📆 WEEK 15 📝 Summary: The official harvest entry will be coming soon. I don’t like updating with dried pictures mid-process - I prefer to drop them when the harvest post is up. ⚙️ Equipment: Hydro tek can feel pretty mundane for me since my crop cycles are so hands-off. Harvest time means it’s also time to break down the RDWC and give it a proper clean. Aquarium pipe cleaners and drill bit neoprene brushes usually do the trick. I’ll also let the system run with a cleaning solution (hydrogen peroxide, diluted bleach, or Heavy 16 Finish depending on the situation) before doing a final rinse and filling it up with nutrient solution. This April is special since the wife and I will be trying out some new nutrient lines soon, along with new dosing syringes for all additives and a fresh 8-layer 3-stage water filtration replacement. RO ratios are looking solid these days, so I might swap soon if the funds allow. It’s also time to replace one of the carbon filters (it failed) and clone collars. The dry tent got a deep clean, and I tested all the attached devices ahead of time. My dry tent setup is simple: the exhaust fan is triggered by the upper RH boundary, and the humidifier by the lower RH boundary, with an external temperature trying to stay steady. Luckily, the timing for the dry is working out with the weather. I’ll be aiming for 60% RH/60°F for about ten days, though I’m still dealing with compressor cycles. In the meantime, I pull air into the dry tent through a carbon filter from the room, with ambient air being affected by the dehumidifier and AC. A disco ball motor turns the hanger, and a clip fan keeps the air moving gently around the tent. ⏳ Timeline & Outlook: Hoping to break out the Temu microscope and maybe connect with someone who has a rosin press for a cool drip video. As for the mother clone I had in limbo, it didn’t make the cut, but I did throw the indica-leaning RuntZ as a female in a breeding project now. The harvest should be done drying by 4/21, and I’m excited to see where we land on dry weight. Final pictures coming soon with the official harvest entry. Right now, the 3x3 is jam-packed with gorgeous, dense, tropical flowers.

ATLien415 🙏 Big thanks to Plagron and Zamnesia for putting on the Eternity Grow Cup 2025. This kind of platform means a lot to the community. The chance to push our grows, test out new techniques, and connect with other cultivators from all over has been inspiring. Appreciate the love and effort that went into making this event happen! Hope everyone enjoyed looking over my shoulder on this grow and best of luck to all participants! REVIEW - Runtz (fem., photo.) from Zamnesia: ⬛⬛⬛⬛⬛⬛⬛⬜⬜⬜ The seeds from Zamnesia germinated rapidly, rooted strongly, went wild in veg, and produced an ample amount of high-quality medicinal flower. The diary speaks for itself on that front so this space will be more of a phenotype review. The plants were labelled A, B, and C from left to right respectively in photos. A and B were the 'clasicaly-appearing' sativa-esque leaves while C was the more 'indica-appearing' phenotype. Although A and B appear the same qualitatively, they did produce substantially different amounts of flower (despite their DLI being near max out for the entire tent footprint without supplementing CO2, so I do not think just being in the middle attributed to this). Past their different yields, A and B also have vastly different profiles. A is a classic gelato/ice cream cooler/Z terps, and my personal favorite of the plants (wish I had taken a clone of this one instead). B is the most on point for what I think of with Runtz, classic Z terps but with a slight tropical/rotten/sweetness to it. C had the misfortune of being ready to chop a little earlier than the other girls so her profile is mostly just spicey kush now. I did observe intersex flower sites but given the entire context of the diary and how the plants performed, I have to assume it was user error. No pollination observed in any of the flowers, as zero additional intersex sites occurred. The distinction between A, B and C is what I would expect from a typical F1 cannabis seed. I do not enjoy growing from seed much but these girls were manageable. Add to that the relative stability of the genetics for a Runtz recreation, and well, these are good quality beans for a great price. Not only is Zamnesia responsive and available, their confidence speaks volumes. How many vendors would have an in-house Runtz, knowing how much of a genetic-gravity-well it is in, and be confident enough to let ~200 randos grow it and show it? REVIEW - Green Sensation from Plagron: ⬛⬛⬛⬛⬛⬛⬛⬛⬜⬜ I enjoyed using the green sensation, the NPK values on it make it versatile in application and a power-house in flower. I can't say I noticed anything better or dramatically improved, although comparing to Heavy 16 and asking for a marked improvement is big ask in my opinion. What I was able to do was seamlessly integrate the Green Sensation into my current routine. The additive stayed homogenous, was easily introduced into solutions with no adverse impact to the water contents or pH. Most importantly, the plants enjoyed the additive and it did accomplish the main goal of being able to wane off your primary line. In this respect, by using Green Sensation I was able to save resources by lowering my Heavy 16 inputs across the board approximately 50% and supplementing with Plagron's Green Sensation.
