Week 2 - Blueberry Muffin (Pheno A) ?🌱
Hello everyone, and welcome back to another update from Project Blue Tent!
For anyone joining the journey for the first time, this run follows multiple cultivars and phenotypes from Zamnesia, with each phenotype receiving its own dedicated diary. By documenting Pheno A and Pheno B separately, we can follow their individual development, compare traits, and observe how each plant expresses its genetics from seed to harvest.
This project is also being conducted under a 12/12-from-seed schedule. Rather than using an extended vegetative period, the plants receive 12 hours of light and 12 hours of darkness from the very beginning. The goal isn’t to grow the largest possible plants, but to efficiently explore genetics, phenotype expression, structure, vigor, and flowering characteristics while maintaining a manageable footprint.
Week 2 Overview
The second week has brought some fantastic progress throughout the tent. Growth has accelerated noticeably, root systems continue to establish themselves, and the plants are beginning to transition from fragile seedlings into young vegetative plants.
PPFD has now been increased to approximately 370 µmol/m²/s, providing more energy as the plants become capable of handling higher light levels. Environmental conditions have remained stable, with temperatures around 27°C during lights-on and 25°C during lights-off. Relative humidity has been maintained near 55% with the help of a humidifier, ensuring a comfortable environment for early growth.
Watering remains deliberately conservative. Each plant received approximately 250 ml on Day 8 and another 250 ml on Day 11. Nutrient levels have also been increased gradually throughout the week. We finished the week at approximately EC 0.9 mS/cm and pH 6.0, allowing the plants to adapt comfortably while monitoring their response.
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 so far has been very encouraging. Healthy color, strong growth, and no signs that the plants are struggling with the increased feeding levels.
Blueberry Muffin Pheno A
This week has been all about proving that first impressions don’t tell the whole story.
During the first week, this phenotype displayed some unusual leaf development. Nothing particularly concerning, but enough to give her a little extra character compared to some of her sisters. Those early quirks are still visible on a few of the older leaves, serving as a reminder of her unique start.
The newest growth, however, tells a completely different story.
Fresh leaves are emerging beautifully formed, symmetrical, and vibrant green. The plant appears to be thoroughly enjoying the gradual increase in nutrition and has responded with noticeably stronger growth throughout the week.
Several new nodes have developed, five-finger leaves have begun appearing, and overall structure is becoming much more defined. The root system continues to establish itself beneath the surface while the canopy steadily expands above it.
One thing that stands out most this week is the color. The foliage carries a rich, healthy green tone that suggests the plant is comfortable, actively growing, and making excellent use of the available nutrition.
At this stage, Pheno A is looking vigorous, healthy, and increasingly confident.
Mr. Baggy Report
Mr. Baggy remains hard at work supervising daily operations throughout the tent. While productivity reports remain difficult to verify, morale appears exceptionally high.
Further investigation is ongoing.
Looking Ahead
If growth continues at the current pace, next week should bring:
• Faster node development
• Larger five-finger leaves
• Increased branching potential
• Stronger stem development
• More visible phenotype traits
Week 3 is often where young plants begin showing much more of their individual personalities, and I’m excited to see what this Blueberry Muffin has in store.
Final Thoughts
Overall, I couldn’t be happier with how Week 2 has progressed. The early leaf quirks that initially caught my attention are becoming less relevant with each passing day as healthy new growth takes over.
A huge thank you to everyone following along, commenting, sharing advice, and supporting the project.
Special thanks to Zamnesia, Plagron, Future of Grow, and the entire growing community helping make this journey possible.
Thank you for stopping by, and I’ll see you all next week for another update from Project Blue Tent.
Growers Love
