💙 Project Blue Tent – Week 4
Blue Waffle F1 – Pheno B (Folder 13B)
Hello everyone, and welcome back to another update from Project Blue Tent!
For anyone joining us for the first time, this project follows four individual Blue Waffle F1 plants from Zamnesia, each documented in its own diary from seed to harvest. Although they all live inside the exact same environment, receive the same nutrition, grow under the same lights and experience the same conditions every single day, every plant is allowed to tell her own story.
That's one of the things I love most about growing from seed.
We're not simply growing four plants.
We're discovering four different personalities.
Everything inside this tent is built around the Zamnesia ecosystem, while the ladies are growing in Plagron Premium Coco Growbags and being fed exclusively with the Plagron Hydro nutrient line.
Today it's time to spend some quality time with Blue Waffle F1 – Plant B.

🌱 Week Four – Small Plant, Big Potential
This week felt like another important milestone for Plant B.
While she remains slightly more compact than her sister, she's developing exactly the way I hoped she would. Her internodal spacing stays beautifully tight, the side branches continue to stack evenly around the main stem, and the overall structure is incredibly symmetrical.
Rather than stretching upwards, she's investing her energy into building a strong foundation first.
Personally, I love seeing this type of growth.
Plants like these often become a dream to train later on because they're naturally dense, balanced and eager to fill every available space once they're encouraged to branch out.
The stem continues to thicken nicely, while subtle purple pigmentation is becoming more noticeable on the petioles and main branches, adding another little touch of personality to this phenotype.

🌡️ The Blue Tent Environment
One of the biggest goals with Project Blue Tent is maintaining consistency.
By keeping every environmental factor as stable as possible, the differences we observe come primarily from the plants themselves rather than changing conditions.
This week's average environmental conditions were:
• 🌡️ Day Temperature: 27°C
• 🌙 Night Temperature: 25°C
• 💧 Relative Humidity: 67%
• ⚗️ pH: 5.8
• ⚡ EC: 1.88 mS/cm
• 💨 CO₂: approximately 450 ppm
• 💡 Light Schedule: 18/6
• ☀️ PPFD: approximately 350
The Zamnesia Phytonaut LED continues providing a beautiful, even light distribution across the entire canopy while the Grow Environment Controller keeps everything running smoothly throughout the day.
Stable conditions allow the plants to focus on one thing...
Growing.

🥥 Feeding Update – Learning Coco One Week at a Time
One thing that really caught my attention this week was the overall leaf colour.
Just like her sister, Plant B remains incredibly healthy, but she's showing a lighter shade of green than I personally like to see.
Fortunately, plants are excellent communicators.
Before deficiencies become serious, they often give subtle hints that they're ready for a little more nutrition, and I believe that's exactly what these ladies were telling me.
Rather than waiting for problems to develop, I decided to make a gradual adjustment.
The feeding schedule is now:
• Plagron Hydro A — 1.8 ml/L
• Plagron Hydro B — 1.8 ml/L
• Plagron Hydro Roots — 1 ml/L
I also introduced a small amount of Plagron pH Min to help keep the reservoir perfectly stable over longer periods.
One thing that has genuinely impressed me throughout this grow is just how stable the Plagron Hydro line has been.
Once the reservoir is mixed and dialled in, the pH barely moves throughout the entire week. Occasionally it may require the smallest correction, but compared to what I expected when starting coco, the stability has honestly been outstanding.
Coming from years of growing in living soil, I'm really enjoying learning how responsive and predictable coco can be when small adjustments are made instead of large corrections.
Growing really is one continuous learning experience.

✂️ Topping Day – Building Tomorrow's Canopy
This week also marked Plant B's first High Stress Training session.
She received her very first topping.
Unlike Low Stress Training, where branches are gently bent into position, topping intentionally removes the plant's main growing tip to interrupt apical dominance.
By doing this, the plant redirects energy into the side branches instead of focusing almost exclusively on one central leader.
Many growers choose to top much earlier, sometimes above the second or third node.
Personally, I prefer allowing the plant to develop a little longer before making that first cut.
Waiting gives me a stronger stem, additional secondary branches and, most importantly, many more growing tips to work with later.
My goal isn't simply to create two tops.
My goal is to build the framework that will eventually fill an entire SCROG net.
Everything we're doing today is preparing these plants for the weeks ahead.
Because topping is considered High Stress Training, timing is important.
I only perform it on vigorous, actively growing plants that are showing strong health.
Although the foliage is still a lighter green than I'd ideally like, Plant B's posture, growth rate and overall vigour clearly showed she was more than ready for the procedure.
The cut itself was made using my Zamnesia Pruning Scissors, giving a clean, precise cut with minimal tissue damage.
Sometimes the smallest tools make the biggest difference.

🌿 Blue Waffle F1 – Plant B
The more time I spend watching this phenotype, the more I appreciate her personality.
She's compact.
She's balanced.
She's methodical.
Rather than racing upwards, she seems determined to build a solid foundation first.
Every branch appears evenly spaced, the stem continues gaining strength, and even after topping she looks completely unfazed.
It's always fascinating how two sister plants can respond so similarly while still expressing their own unique character.
Plant B feels like the quiet achiever.
She's simply getting on with the job.

👀 Looking Ahead
Next week should be a very exciting one.
With the feeding now increased and the topping behind her, I'll be watching closely to see how quickly the two new leaders begin taking over.
I'm expecting the canopy to start opening naturally as the side branches accelerate and the overall structure becomes wider.
Over the coming weeks we'll continue shaping these ladies, preparing them for the SCROG while allowing each phenotype to reveal more of its own personality.
The adventure is only just beginning.

💙 Thank You
A huge thank you goes to Zamnesia for making Project Blue Tent possible, from these fantastic Blue Waffle F1 genetics to the complete ecosystem surrounding this grow.
A heartfelt thank you as well to Plagron for providing the Premium Coco Growbags together with the Hydro nutrient line that continues teaching me something new every single week.
Thank you to GrowDiaries for giving growers from around the world a place to document their journeys, learn from one another and build such an incredible community.
And finally...
Thank you to every single person following along.
Whether you've been here since day one, recently discovered these diaries, leave comments every week, quietly observe from the background or simply enjoy watching these plants develop, your support truly means a lot.
I hope you're all having an amazing week, and I can't wait to show you how these beautiful ladies continue evolving in the next update.
Until then...
Growers Love, happy growing, and I'll see you all next week. 🌱💙
P.S. One thing I love about documenting every single step is that these diaries become more than simple grow logs. Hopefully someone who has never topped a plant before can look at this week's photos, understand the process, see exactly where the cut was made, and feel a little more confident when the time comes to do it themselves. If these updates help even one grower become more confident with their own garden, then they've already achieved something special. 💙🌱
