💎 Black Diamond Auto by Zamnesia – Pheno B
Week 9 | The Other Beast 💎🔥
Welcome back to another chapter of the 8×8 Adventure!
Well...
Her sister is doing her thing.
And if you've been following this adventure, you already know what that means.
Pheno A is in full beast mode. 😂💎
She's massive.
She's loaded.
She's throwing flowers everywhere.
And she's making sure nobody forgets she's in the room.
But then I look at her sister...
And I have to smile.
Because Pheno B is also a beast.
Just a different kind.
And that's exactly what makes these two so fascinating.
Same genetics.
Same room.
Same light.
Same nutrition.
Same irrigation.
Same environmental conditions.
Both beautiful.
Both vigorous.
Both now cleaned up with some selective defoliation.
Both entering this increasingly exciting stage of flowering.
And yet...
very, very different.
That's phenotype hunting.
And I absolutely love it.
🌱 One Room. Two Black Diamond Stories.
The 8×8 Adventure was never about making twelve plants look identical.
Quite the opposite.
The whole point was to give different genetics and phenotypes the same ecosystem and then watch what they decide to do with it.
Twelve plants.
One room.
12/12 from seed.
One general nutritional strategy.
One environmental strategy.
One lighting ecosystem.
And then...
genetics take over.
Black Diamond Pheno A has developed one expression.
Black Diamond Pheno B has developed another.
They're sisters.
But they're definitely not twins.
😂💎
And at Week 9, that difference is becoming impossible to miss.
💎 The Other Beast
Last week, I was talking about Pheno B as the quieter sister.
The more reserved phenotype.
The one that wasn't necessarily trying to dominate the room.
Well...
I may need to revise that description slightly.
😂
Because this girl has been steadily building.
And now?
She's a beast too.
Standing around 160 cm, she's developed into a beautiful, substantial flowering plant.
But her strength isn't expressed exactly like her sister's.
Where Pheno A seems to throw herself into flower production with almost reckless enthusiasm, Pheno B has that more controlled, elegant architecture.
She's still tall.
She's still heavily branched.
She's still carrying flowers throughout her structure.
She's still becoming increasingly frosty.
She's just doing it in her own way.
And that's what I want to document.
Not which sister is “better.”
But how differently two phenotypes can express themselves when everything around them is kept so similar.
✂️ The Beast Got a Little Grooming
This week, just like her sister, Pheno B received some selective defoliation.
Again...
Nothing extreme.
We're not trying to strip the plant down.
We're simply opening some space where the canopy has become crowded.
A few leaves needed to come out.
Some areas benefited from additional breathing room.
And as flowering progresses, maintaining a sensible balance between foliage, airflow and flower visibility becomes increasingly important in a room containing this many plants.
The goal isn't to change her personality.
It's to reveal it.
And I think that's exactly what happened.
After the cleanup, you can appreciate the structure much more clearly.
The flowering sites become easier to see.
The branches become easier to follow.
And suddenly you realize just how much she's actually carrying.
🌿 Similar Sisters. Very Different Personalities.
This is probably my favourite part of this week's update.
Put Pheno A and Pheno B next to each other and you immediately know they're related.
There are similarities.
The overall flower development.
The vigorous growth.
The healthy foliage.
The general Black Diamond character.
But then you start looking closer...
And the differences appear.
Their architecture isn't the same.
Their flower distribution isn't exactly the same.
Their proportions aren't the same.
Their way of occupying the room isn't the same.
Their personalities aren't the same.
And that's the magic.
Same family. Different handwriting.
One sister says:
"Give me the whole tent."
The other says:
"I'll take my space, thank you very much."
😂💎
And somehow...
both are absolutely beautiful.
🌸 Flower Development Is Getting Serious
At this point in the flowering cycle, the flowers are becoming increasingly defined.
The calyxes are stacking.
The pistils remain abundant.
The developing buds are gaining structure and volume.
And the resin is becoming much more obvious.
Looking through this week's photographs, that's one of the first things that catches my eye.
She's getting frostier.
The sugar leaves are beginning to disappear underneath the resin.
The developing flowers are becoming increasingly coated.
And we're still watching that transformation happen week by week.
This is where the earlier weeks of growth start paying off.
The branches we watched develop.
The flowering sites we watched appear.
The structure we watched form.
Now they're all becoming flowers.
And that is incredibly satisfying to watch.
❄️ The Frost Is Arriving
I particularly like the close-ups this week.
You can see that the resin coverage is becoming much more apparent across the developing flowers and sugar leaves.
She's not finished.
We're not at the end of the story.
But the direction is very clear.
She's getting frosty.
And I have a feeling that the coming weeks are going to make these photographs even more interesting.
This is one of those moments where the plant starts changing visually in a way that's immediately noticeable.
Every update seems to bring another layer.
More structure.
More resin.
More density.
More personality.
🍃 Healthy Green, Beautiful Structure
One of the things I continue to appreciate about Pheno B is her overall appearance.
She's maintaining that rich, healthy green.
The foliage remains vigorous.
The plant has enough leaves to support continued flower development while still responding well to the selective cleanup we've given her.
And this is important.
Defoliation isn't the objective.
A healthy, functional plant is the objective.
If a leaf is doing its job, that's valuable.
If removing a leaf improves the overall structure of a crowded canopy, that can also be valuable.
It's always a balance.
And with this girl, I think we've found a nice middle ground.
She's still lush.
She's still green.
She's still unmistakably herself.
But now there's a little more room to appreciate what she's building underneath.
💡 Light From Above and Below
The lighting experiment continues to be particularly interesting with these two sisters.
The main Future of Grow lighting provides the primary overhead illumination.
The Lumiflora under-canopy lighting adds another layer of usable light lower within the plant.
And with Pheno B's architecture, there's plenty to observe.
She's tall enough that different parts of the plant naturally experience different light levels.
At the same time, her structure isn't identical to Pheno A's.
So once again, the same lighting system is interacting with a different phenotype.
That's exactly what I want from this experiment.
Not assumptions.
Observation.
We give them the same opportunity.
Then we watch how differently they use it.
💧 Feeding the Black Diamond
The flowering nutrition continues according to the same general program used throughout the room.
🌸 Terra Bloom — 2.2 ml/L
🌱 Power Buds — 1 ml/L
✨ Green Sensation — 1 ml/L
🍯 Sugar Royal — 1 ml/L
⚗️ pH Plus — 0.03 ml/L
🍋 Lemon Kick — 0.03 ml/L
Current solution is around pH 6.0 with an EC of approximately 2.0 mS/cm.
Watering is around 1.3 L per plant / 24h.
And once again, the important part is consistency.
Pheno B isn't receiving some secret recipe that her sister doesn't get.
She's living in the same ecosystem.
And yet...
she is expressing herself differently.
That's the information I'm interested in.
🌡️ Current Conditions
Current conditions for Week 9:
🌸 Flowering: Week 9
📏 Height: 160 cm
💡 Light schedule: 12/12
🌡️ Day temperature: 29°C
🌙 Night temperature: 25°C
💧 Relative humidity: 60%
⚗️ pH: 6.0
⚡ EC: ~2.0 mS/cm
💧 Solution temperature: 25°C
🌱 Substrate temperature: 26°C
🌬️ CO₂: 636 ppm
? Pot size: 15 L
💦 Watering: ~1.3 L per plant / 24h
The environment remains stable.
And that's exactly what allows the comparison between phenotypes to become so interesting.
The environment stays relatively constant.
The plants write the differences.
📸 This Week's Gallery
The photographs this week really show why this girl deserves her own spotlight.
The wider shots show her overall architecture.
She's tall.
She's developed.
She's carrying flowers throughout her structure.
And after the cleanup, those flowers are much easier to appreciate.
The close-ups tell the other part of the story.
Fresh pistils.
Developing calyxes.
Increasing resin.
More defined flower structure.
More frost.
And then you look at her sister...
And you realize:
These two really are very different.
Similar enough that you immediately know they're related.
Different enough that you could never confuse one personality for the other.
And honestly?
That's exactly what I hoped this experiment would show.
💎 The Sisterhood of the Beast
I think we can officially say it now.
Both Black Diamond sisters are beasts.
Pheno A is doing her thing.
Pheno B is doing hers.
Both have been cleaned up.
Both are carrying serious flowers.
Both are getting increasingly frosty.
Both are looking beautiful.
But they are absolutely not the same plant wearing different labels.
😂💎
And that's the beauty of it.
You can give two sisters the same room, the same treatment and the same opportunity...
and they'll still find their own way.
🔮 Looking Ahead
Now I'm watching for the same things I've been watching across the rest of the room:
🌸 Flower swelling
❄️ Increasing resin production
🌿 Continued canopy health
💎 Development of the lower flowers
🍃 Response to the selective defoliation
🔬 Overall maturation
And, of course...
I'm watching the sisters.
Because now that both are entering this heavier flowering stage, the comparison is becoming even more fascinating.
Will Pheno B continue building at her own steady rhythm?
Will the differences between them become even more pronounced?
Will the flowers develop differently as they mature?
That's what we're here to find out.
💚 Let This Girl Shine
I think this girl has earned her own moment.
She's not Pheno A.
And she doesn't need to be.
She's Black Diamond Pheno B.
She's developed her own architecture.
Her own rhythm.
Her own flower distribution.
Her own personality.
And now she's showing us another version of what this genetic line can produce.
Her sister may be running around the room in full beast mode...
but this girl?
She's right there with her.
Just in her own style.
😂💎🌿
So we cleaned her up.
We opened some space.
We gave her a little room to breathe.
And now...
let's watch her shine.
Because she's earned it.
💎 Final Thoughts
Week 9 is another reminder of why I love this 8×8 Adventure so much.
Two Black Diamond plants.
Same genetics.
Same room.
Same environment.
Same general feeding.
Same lighting.
Same irrigation.
And still...
two completely different stories.
Pheno A is explosive.
Pheno B is more composed.
Pheno A seems determined to turn everything into a cola.
Pheno B has her own way of building.
But both are beautiful.
Both are vigorous.
Both are becoming increasingly frosty.
Both needed a little cleanup.
And both are showing us just how much personality can exist inside the same genetic line.
That's phenotype hunting.
You don't tell the plant what story to tell.
You create the conditions...
and listen.
And this girl is speaking very clearly now.
"I'm not my sister."
"I'm my own beast."
And you know what?
I absolutely love that.
Let's make her shine. 💎💚🌿
