Week 2 - Cash Express (Pheno A) 💸🌱
Hello everyone, and welcome back to another update from the 8×8 Adventure!
For anyone joining the journey for the first time, this run follows multiple Zamnesia cultivars and phenotypes grown side-by-side under a 12/12-from-seed schedule. Each phenotype receives its own dedicated diary so we can document individual development, compare expressions, and observe how different plants reveal their genetics from seed to harvest.
By documenting Pheno A and Pheno B separately, we can follow each plant’s individual story from seed to harvest. Some phenotypes develop similarly, while others immediately begin showing their own personality. Cash Express Pheno A has already made it clear that she belongs in the second category.
This project is conducted entirely under a 12/12-from-seed schedule. Rather than extending the vegetative period, the plants receive 12 hours of light and 12 hours of darkness from day one. The goal is not maximum plant size but rather an efficient exploration of genetics, structure, vigor, and flowering characteristics while maintaining a manageable garden.
Week 2 Overview
The second week has brought excellent development throughout the entire room. Seedlings are rapidly transitioning into young vegetative plants, root systems continue expanding beneath the surface, and growth rates have noticeably increased compared to the first week.
PPFD has now been increased to approximately 370 µmol/m²/s, providing additional energy as the plants become capable of handling stronger light levels.
Environmental conditions remained stable throughout the week:
• Light Schedule: 12/12
• Day Temperature: 27°C
• Night Temperature: 25°C
• Relative Humidity: 55%
• Solution Temperature: 20.1°C
• Substrate Temperature: 21°C
• CO₂: Ambient (~600 ppm)
Watering remains intentionally moderate at this stage. Each plant received approximately 250 ml on Day 8 and another 250 ml on Day 11. Nutrient levels were gradually increased throughout the week as the plants continued responding positively to feeding.
Week-ending values:
• EC: 0.9 mS/cm
• pH: 6.0
Current feeding schedule:
• Terra Grow – 1.8 ml/L
• Pure Zym – 1 ml/L
• Power Roots – 1 ml/L
• Sugar Royal – 1 ml/L
The response across the room has been extremely positive, with healthy color, strong growth, and no signs of nutrient stress.
Cash Express Pheno A
This phenotype appears to have received one simple instruction from the start:
Grow.
And keep growing.
While the rest of the room is developing nicely, Cash Express Pheno A seems determined to stay one step ahead of the pack.
At only Week 2 she is already establishing herself as one of the most vigorous plants in the entire 8×8 Adventure. Growth has been rapid, consistent, and balanced, with every new set of leaves emerging larger than the last.
The first thing that stands out is her size.
Even compared to her own sister phenotype, the difference is becoming noticeable. For that reason, a few comparison photos have been included in this update so readers can easily see the contrast without needing to jump between diaries.
The second thing that stands out is the quality of the growth.
Leaf structure is excellent.
Symmetry is excellent.
Color is excellent.
Node development is uniform and well spaced.
From the very beginning, this plant has shown remarkably clean development, producing healthy leaves with excellent shape and vibrant green coloration throughout the canopy.
There are no strange growth patterns to investigate.
No unusual leaf morphology.
No signs of hesitation.
Just healthy, confident growth.
Sometimes the most exciting phenotype is not the weird one.
Sometimes it’s the one that simply does everything right.
And right now, Cash Express Pheno A is doing exactly that.
Development Notes
During Week 2, the plant continued building structure at an impressive pace.
Five-finger leaves are now clearly established and becoming increasingly prominent. New growth remains vigorous, internodal spacing looks balanced, and the plant is developing the strong foundation needed for the coming weeks.
The canopy continues expanding evenly while maintaining excellent symmetry from side to side.
Overall, this phenotype currently represents one of the strongest examples of healthy early vegetative development in the room.
Mr. Baggy Report
Mr. Baggy remains actively involved in daily operations throughout the 8×8 Adventure.
Current responsibilities include growth inspections, environmental supervision, quality control assessments, and occasional morale boosting.
His enthusiasm remains considerably higher than his documented productivity.
Looking Ahead
If development continues at the current pace, next week should bring:
• Significant canopy expansion
• Larger five-finger leaves
• Additional node development
• Stronger stem growth
• Increased branching potential
• Further phenotype expression
At the moment, Cash Express Pheno A appears determined to lead from the front, and it will be exciting to see whether she can maintain that momentum as the project progresses.
Final Thoughts
Week 2 leaves me extremely impressed with this phenotype.
Healthy growth.
Excellent structure.
Beautiful foliage.
Strong vigor.
Everything about this plant suggests she has settled comfortably into her environment and is eager to continue pushing forward.
While many plants reveal their personality through unusual traits, Cash Express Pheno A is making her statement through pure performance.
For now, she seems to have only one destination in mind:
The moon.
A huge thank you to everyone following along, commenting, sharing advice, and supporting the project.
Special thanks to Zamnesia, Plagron, Future of Grow, and everyone helping make this journey possible.
Most importantly, thank you to the entire growing community for continuing to share knowledge, encouragement, and passion for growing.
Thank you for stopping by, and I’ll see you all next week for another update from the 8×8 Adventure.
Growers Love
