🌱 Week 4 - Black Diamond Auto - Plant A
8×8 Adventure | Learning What Nature Wants to Teach
Another week has passed inside the 8×8 Adventure, and every day reinforces why this project is so exciting.
Unlike traditional autoflower grows, every plant in this room was germinated directly under a 12/12 light schedule. There was never a long vegetative period waiting before flowering. Instead, each plant has had to build its entire structure while already living under flowering conditions.
It is a technique that fascinates me because it reveals just how different every individual phenotype can be.
Some decide to begin flowering almost immediately.
Others invest precious time building roots and branches before finally committing to reproduction.
That is exactly why every plant receives its own diary.
This week belongs to Black Diamond Auto - Plant A.

🌿 A Completely Different Personality
While several sisters have already started showing obvious flowering characteristics, this lady had other plans.
Instead of rushing toward bloom, she kept investing energy into building herself.
The result is becoming obvious.
She is developing into one of the strongest structural plants inside the room.
Long internodes.
Strong branches.
Excellent vigor.
Beautiful symmetry.
She almost seems to be saying,
“I’m not in a hurry… I’m building something worth waiting for.”
Sometimes the slow starters end up becoming the biggest surprises.
⸻
🌱 Why Growing Under 12/12 Is So Interesting
One thing I always enjoy explaining is why this project exists in the first place.
Most growers veg their plants for several weeks before switching lights to 12/12.
Here, the challenge is completely different.
The plants experience flowering light from the day they emerge.
That means every single day matters.
Every root developed…
Every leaf produced…
Every branch formed…
…is competing against the plant’s internal biological clock.
Watching each phenotype decide how it responds to that pressure is one of the most educational parts of this entire adventure.
⸻
🌿 Gentle Training Instead of Force
This week continued with very gentle Low Stress Training.
Rather than forcing dramatic bends or aggressive shaping, I’m simply helping light reach every future flowering site.
Leaf tucking.
Soft branch positioning.
Small adjustments every day.
Sometimes even gently bending large fan leaves out of the way instead of removing them.
At this stage every healthy leaf is still acting like a solar panel, producing energy for everything that comes next.
The goal isn’t to force the plant into a shape.
The goal is to guide her while allowing genetics to express themselves naturally.

💧 A New Chapter Begins: AutoPot Time
One of the biggest milestones this week is that Plant A has officially graduated into the AutoPot system.
This is something I’ve been looking forward to throughout the entire grow.
For anyone unfamiliar with AutoPots, they are a completely passive self-watering system.
There are no pumps.
No timers.
No electricity controlling irrigation.
Instead, everything revolves around one incredibly clever little device called the AquaValve.
The AquaValve constantly monitors the water level inside the tray beneath the pot.
As the plant drinks, the tray empties.
Only then does the AquaValve automatically open, allowing fresh nutrient solution to refill the tray before closing again.
This creates a natural wet-and-dry rhythm while giving the roots constant access to perfectly oxygenated nutrient solution whenever they need it.
The plant decides when to drink.
Not me.
It’s a beautiful example of letting nature control the schedule.
⸻
🔬 Why This Is Such A Fun Experiment
Even more interesting…
Plant A won’t be alone for long.
The current plan is to compare her performance against another Black Diamond that may remain outside the AutoPot system.
Same genetics.
Same room.
Same environment.
Different irrigation method.
It’s still early, so I won’t draw any conclusions yet, but this comparison could become one of the most educational parts of this entire project.
Sometimes the best lessons come from simply letting the plants answer the questions for us.

🌡️ Environment
The room continues running very consistently.
Environment
• 🌡️ Day Temperature: 33°C
• 🌙 Night Temperature: 25°C
• 💧 Relative Humidity: 63%
• ⚡ EC: 1.35
• pH: 6.1
• 💨 CO₂: 639 ppm
• 💦 Solution Temperature: 26°C
Even with the warmer daytime temperatures, the plants continue showing healthy metabolism and vigorous growth.
⸻
🍽️ Feeding This Week
Current nutrient program:
• Terra Grow — 1.8 ml/L
• Power Roots — 1 ml/L
• Pure Zym — 1 ml/L
• Sugar Royal — 1 ml/L
The feeding remains intentionally balanced.
No need to chase high EC values while the plant is still investing heavily into structural growth.
Healthy roots first.
Strong stems second.
Flowers will come naturally.

🌱 Looking Ahead
By the end of the week, she’s finally beginning to show the first signs that flowering is approaching.
Nothing explosive yet.
Just those subtle little changes every grower loves spotting:
slightly tighter node spacing…
new vertical growth…
the first hints that she’s preparing to transition.
Considering the structure she’s already built, I have a feeling she could become one of the larger plants in this room.
Only time will tell.
And that’s half the fun.

💚 Final Thoughts
One of my favourite things about this hobby is that every plant writes its own story.
We provide the environment.
The nutrition.
The light.
The care.
But ultimately, genetics decide how the story unfolds.
Plant A is teaching patience.
She’s showing that not every plant needs to sprint into flower to become something special.
Sometimes building a strong foundation is the smartest strategy of all.
I’m excited to see what she becomes over the next few weeks.
