💙 Project Blue Tent – Week 5
Blue Waffle F1 – Pheno B (Folder 13B)
Hello everyone, and welcome back to another chapter of Project Blue Tent.
For anyone discovering these diaries for the first time, this project follows four individual Blue Waffle F1 plants from Zamnesia from seed to harvest. Every plant grows inside the exact same environment, under the same lighting, receives the same nutrition and follows the same schedule.
The only variable...
The genetics.
Watching each phenotype develop its own personality while removing as many environmental variables as possible is exactly what makes this project so fascinating.
Today we're checking in with Plant B.
🌱 Week Five – Finding Her Rhythm
If last week was about recovery after topping, this week was all about momentum.
Plant B responded beautifully to the cut, quickly redirecting her energy into the new leading shoots while the lower branches accelerated their own growth.
She's still carrying that compact structure I mentioned previously, but she's beginning to spread out much more naturally now. The canopy is becoming wider, the internodal spacing remains wonderfully tight, and every branch seems determined to compete for the top.
One thing that continues to impress me is how symmetrical she is becoming.
She almost looks like she planned every branch herself.
The stem has thickened considerably over the past week, giving me confidence that she'll comfortably support the heavy flowers later in the grow.
🌡️ Blue Tent Environment
Consistency continues to be the biggest priority inside the Blue Tent.
This week's average conditions were:
• 🌡️ Day Temperature: 30°C
• 🌙 Night Temperature: 25°C
• 💧 Relative Humidity: 58%
• ⚗️ pH: 5.8
• ⚡ EC: 1.92 mS/cm
• 💨 CO₂: 450 ppm
• 💡 Light Schedule: 18/6
• 💧 Irrigation: 1.2 litres per plant per day
Although daytime temperatures climbed slightly this week, the plants continued growing vigorously with no signs of stress, demonstrating just how resilient healthy plants become when the root zone remains stable.
🥥 Feeding & Irrigation
One of the biggest differences between this project and my previous organic soil grows is the irrigation strategy.
Because coco doesn't store nutrients the same way soil does, the plants are fed little and often rather than receiving larger irrigations every few days.
Each plant now receives approximately 1.2 litres of nutrient solution every day through the automatic Mars Hydro drip irrigation system.
A drip irrigation system slowly delivers nutrient solution directly onto the growing medium through small emitters positioned at each plant. Rather than watering by hand, every irrigation is delivered evenly and consistently, ensuring every plant receives exactly the same amount.
Once the nutrient solution has travelled through the coco, the excess runoff drains away through the automatic drainage system beneath each grow bag.
This is just as important as the irrigation itself.
Removing runoff prevents old nutrient solution from accumulating around the roots, helping maintain a healthier and more stable root environment while dramatically reducing the daily workload.
As someone who has spent years hand-watering plants, I genuinely appreciate how much time this system saves while improving consistency at the same time.
The current feeding schedule is:
• Plagron Hydro A — 1.9 ml/L
• Plagron Hydro B — 1.9 ml/L
• Plagron Hydro Roots — 1 ml/L
The slight increase from last week continues producing exactly the response I was hoping for, with richer colour and strong, healthy new growth.
🕸️ Preparing the SCROG
This week also marked another exciting milestone.
The SCROG net officially entered the grow.
SCROG stands for Screen Of Green.
Rather than allowing each branch to grow vertically on its own, a horizontal net is placed above the canopy. As branches grow through the openings they're gently guided sideways, encouraging the plant to spread across the entire growing area.
Instead of producing one dominant cola, the plant develops dozens of equally exposed flowering sites.
The result is a flatter canopy, more efficient light distribution and, hopefully, a much larger overall harvest.
At this stage the net isn't there to hold flowers.
It's there to guide the architecture of the plant.
Over the coming weeks I'll continue weaving each branch through the net one square at a time, allowing the canopy to fill naturally before flowering begins.
Watching this process unfold is honestly one of my favourite parts of growing.
🌿 Blue Waffle F1 – Plant B
Plant B continues living up to the personality she's been developing since the beginning.
Calm.
Balanced.
Methodical.
She isn't trying to be the tallest plant in the tent.Instead she's quietly building an incredibly organised structure that should become a fantastic SCROG candidate over the next few weeks.
Sometimes the plants that grow the slowest early on end up delivering the biggest surprises later.
I'm very curious to see whether she's one of them.
👀 Looking Ahead
Next week should be all about training.
With the SCROG now installed and both new leaders growing strongly after topping, the real canopy shaping begins.
From here onwards the objective changes completely.
We're no longer trying to grow taller plants.
We're trying to grow wider ones.
Every branch will now be guided with one simple goal...
To create an even canopy capable of making the absolute most of every photon produced by the Zamnesia Phytonaut LED.
The adventure is becoming even more exciting.
💙 Thank You
A huge thank you goes to Zamnesia for making Project Blue Tent possible, from these incredible Blue Waffle F1 genetics to the complete ecosystem surrounding this grow.
A heartfelt thank you to Plagron for providing the Premium Coco Growbags together with the Hydro nutrient line that continues making my transition into coco both enjoyable and educational.
A special thank you to Mars Hydro for the automatic drip irrigation and drainage system that has become an essential part of this project. Although this isn't a sponsored product, it's one of those pieces of equipment that simply works. It has brought consistency, cleanliness and peace of mind to the grow room while allowing me to spend more time with the plants and less time managing runoff.
Thank you to GrowDiaries for giving growers from all 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 reading these updates.
Whether you've been here since the first seed cracked, recently discovered Project Blue Tent, leave comments every week, quietly follow along, or simply enjoy the photographs, every visit, every conversation, every question and every word of encouragement helps make this journey even more rewarding.
I hope you're all having an amazing week, and I can't wait to share the next chapter of this adventure with you.
Until then...
Growers Love, happy growing, and I'll see you all next week. 🌱💙
