Zamnesia Eternity Cup - Grow Diary: Runtz
Welcome to my grow diary for the Zamnesia Eternity Cup! I'm thrilled to participate with one of the most iconic strains: Runtz. This journal documents every step of my journey, showcasing the resilience and beauty of this cultivar. Let’s dive into the details!
Day 0: The Beginning
I kicked off the grow with the tried-and-true glass of water method. It’s always exciting to see those first signs of life, and the Runtz beans didn’t disappoint! They popped quickly, displaying their eagerness to grow strong and healthy. 🌱
Day 3: Seedlings Emerge
Despite the temperature hovering at the lower end of the ideal range (21–22°C), these beans didn’t mind at all. They sprouted into wonderful little seedlings, full of potential and promise. Their vigor is already shining through!
Day 6: Overcoming Challenges
All three seedlings emerged with their seed coats still attached. A small challenge, but nothing I couldn’t handle. Using a pair of sterilized tweezers, I gently removed the seed husks two days after they poked their heads out of the soil. The result? Instant transformation! As soon as the husks were gone, the cotyledons opened up like little green suns, soaking in the light and energy. 🌞
Day 16: End of Germination
After 14 days, I transplanted the seedlings into 7-liter pots to see how well the young plants would respond to the new environment. I’m happy to report that all three seedlings took the transplant like champions! 🌱💪
By the 16th day, the second set of true leaves had formed, marking the end of the germination phase for me. Now it’s time for the final selection—space limits me to only one plant.
Here’s the current status:
Two plants are neck and neck, showing very similar growth patterns.
One plant is pushing ahead with slightly faster growth but has a yellowish top. However, this doesn’t seem to slow it down.
All three seedlings have vibrant green stems and look incredibly healthy. So far, this batch shows the least phenotypic diversity I’ve ever encountered, which makes the decision even harder. In the next update, I’ll reveal which plant makes the cut to continue this journey.
Why I’m Hyped
Runtz is known for its incredible flavor profile, high THC content, and stunning visual appeal. I’m determined to push this strain to its limits and showcase its full potential in this competition. With the right care and attention, I’m confident these seedlings will grow into showstoppers.
What’s Next?
Stay tuned as I document every milestone, from early veg to harvest. I’ll share photos, observations, and tips as I go along, all while keeping my eyes on the prize—the Eternity Cup!
Let’s grow greatness together. 💪🌱✨

Week 2: The Growth Phase Begins
The germination phase is officially behind us, and it’s time to kick off the vegetative growth phase. I’ve uploaded a video that showcases the entire start of this grow diary, from germination to where we are now. 🌱📹 Be sure to check it out for a full recap!
This week marks a critical step in the journey: Pheno Selection. I’ll carefully evaluate the three seedlings and choose the one that will move forward in this competition. So far, the plants are neck and neck, but slight differences are starting to emerge. By the end of the week, the strongest contender will take center stage.
In addition to the video, I’ll be sharing photos of the seedlings as they settle into their new phase of life. Stay tuned for updates on their progress and my final decision.

I have now eliminated the slowest pheno and plan to select the final winner at the beginning of next week. I’m still very impressed by how fast #2 is pushing forward. I suspect that the lighter tips might be a result of this rapid growth. I’ll continue monitoring it closely, as it remains my secret favorite. 🌱🔥
To make the best decision, I plan to review other grow diaries and compare my phenos against them. #1 is also an interesting contender, with slightly rounder leaves and less internodal stretching, but still showing strong growth.
The race remains exciting! 🚀
This week, I only provided pH-adjusted water with 2 ml of Root to support healthy development. Next week, I’ll begin topping, which will reveal how the plants respond to training and help me finalize my selection.
Overall, the plants are looking very healthy, and I couldn’t be prouder! 🌱💪

Final Pheno Selection & Growth Adjustments
I have made my final decision—we are going with the largest pheno, #2! After scouting various Blueberry strains, I noticed similar growth patterns, which helped confirm my choice. The other two phenos grew evenly until the very end, but now they have been officially eliminated. RIP. 🌱⚰️
The basement is still a bit cold, so I plan to add a heater this week to raise the night temperatures to 22°C. Since there hasn’t been much side growth yet and I’ll be growing in a 60x60 tent with a 20L pot, I estimate that she will need at least another month in veg before flipping to flower. To avoid unnecessary delays, I decided to top her, which should help achieve my goal of a well-filled canopy. 🌿✂️
All three phenos had relatively rounded leaves, resembling Indica-leaning hybrids. I believe I selected the most Sativa-leaning pheno, but since none of them had developed significant side branches yet, it's hard to say for sure.
Overall, I’m happy with my choice, and I’m excited to see how she develops in the coming weeks! 🚀🌱

Handling Low Temperatures & Strong Growth
This week, we faced low temperatures, but thankfully, the root heater helped to stabilize conditions. Despite the chill, Runtz is thriving and pushing forward with impressive growth! 🌱🔥
My grow buddy mentioned that the light green leaf tips could be a sign of rapid growth—I really hope that applies to the buds later on as well! 🤞
I topped the plant, and she responded as expected. During this transition phase after topping, I always find it tricky to judge whether the plant is bouncing back healthy. When there’s lots of side branch growth, it's clear that everything is going great, but since topping changes growth patterns, it’s not always easy to assess.
So far, everything looks solid—the main stem healed well, and the bands don’t seem to stress the plant too much. By the end of the week, the lowest branches have already grown past the main leaves, showing strong progress! 🚀🌿
Since the leaf stems are developing a noticeable red coloration, I’ve decided to hold off on further training for now.
