๐ Project Blue Tent โ Week 7
Blue Waffle F1 โ Pheno B (Folder 13B)
Hello everyone, and welcome back to another chapter of Project Blue Tent! ๐๐ฑ
If you're joining us for the first time, welcome aboard.
Project Blue Tent follows four individual Blue Waffle F1 plants from Zamnesia, each documented separately from seed all the way through harvest.
All four sisters share the same environment, lighting, nutrition, irrigation and training techniques.
The idea is simple:
Keep the environment as consistent as possible and let the genetics tell the story.
And despite all those similarities, each plant still manages to develop her own little personality.
Today we're checking in with Blue Waffle F1 โ Plant B.
And if you've been following her journey...
You might remember that this is the girl who had a rather unexpected visitor last week. ๐
Don't worry.
She's absolutely fine.
In fact, judging by the way she's growing...
She seems to have completely forgotten it ever happened.
โโโโโโโโโโโโโโโโโโโโโโโโ
๐ฟ Week Seven โ The Canopy Is Ready
This week feels like the end of one chapter and the beginning of another.
For several weeks we've been building the canopy.
Topping.
Training.
Guiding branches.
Installing the SCROG.
Tucking shoots underneath the net.
Slowly filling every available space.
And now...
We've done it.
The canopy is essentially where I want it.
Plant B is sitting at approximately 60 cm, just like her sisters, with the SCROG keeping the plants at a remarkably even height.
Looking from above, it's becoming increasingly difficult to distinguish one phenotype from another.
That's actually one of the most fascinating things about this project.
Four individual plants.
Four individual diaries.
And yet, under identical conditions, they're producing an incredibly uniform overall canopy.
Plant B has once again filled her section beautifully.
She's healthy, vigorous and absolutely covered in potential flowering sites.
So now it's time for the final preparation before we flip.
โโโโโโโโโโโโโโโโโโโโโโโโ
๐ธ๏ธ The SCROG Mission โ Completed
The SCROG has been one of the most important pieces of the puzzle during this vegetative cycle.
Instead of allowing the plants to develop a few dominant vertical tops, we've spent weeks encouraging the branches to grow horizontally across the screen.
Every time a shoot tried to escape upward, we'd gently guide it underneath the net and into the next available square.
Slowly...
The empty spaces disappeared.
And eventually, the screen became one continuous canopy.
That's exactly what we wanted.
The purpose isn't simply to keep the plants at 60 cm.
It's to distribute the growing tips across the available light and create a more uniform structure for flowering.
And Plant B has handled the entire process beautifully.
Now that the screen is full, however, our priorities are changing.
We're no longer trying to add more foliage.
We're preparing the foliage we already have.
โโโโโโโโโโโโโโโโโโโโโโโโ
โ๏ธ Defoliation โ The Final Vegetative Cleanup
This week's main event is defoliation.
And this is an important distinction:
Defoliation isn't about removing leaves because they look ugly.
It's not about trying to make the plant look "clean."
And it's certainly not about stripping every leaf from the plant.
Leaves are the plant's solar panels.
They're valuable.
So the objective is selective removal, not destruction.
After several weeks of vigorous vegetative growth and SCROG training, the interior of the canopy has become extremely dense.
There are leaves overlapping one another.
Branches crossing through crowded areas.
And sections of the plant where airflow and light penetration can be improved simply by removing some unnecessary foliage.
That's what we're addressing now.
We're opening the plant.
Creating breathing room.
Improving visibility.
And preparing the structure for the much denser environment that flowering will bring.
โโโโโโโโโโโโโโโโโโโโโโโโ
๐ฌ๏ธ Why Do This Before Flower?
This timing is very deliberate.
Defoliation is a form of stress.
Even when performed correctly, removing a substantial amount of foliage temporarily forces the plant to adjust to a new balance between its leaves, roots and active growing points.
So I want that recovery to happen before flowering begins.
We're still running an 18/6 vegetative schedule.
The plants are actively growing.
They have time to recover.
And we're not simultaneously asking them to transition into a completely different developmental phase.
Once flowering begins, I want the plant's attention moving toward flower development rather than recovering from major structural work.
So we're following a very simple sequence:
Build the canopy.
Fill the screen.
Defoliate.
Recover.
Flip.
One step at a time.
โโโโโโโโโโโโโโโโโโโโโโโโ
๐ง What Defoliation Actually Achieves
There's a common misconception that removing leaves automatically means more light equals more growth.
It's not quite that simple.
The reason we're doing this is to improve the overall efficiency of the canopy.
We're trying to create a better relationship between:
๐ฑ Growing sites
๐ก Light penetration
๐ฌ๏ธ Air movement
๐ Leaf density
? Plant structure
The upper canopy is already receiving plenty of light.
What concerns me more is what happens underneath it.
A dense interior can become a maze of overlapping leaves and branches.
By selectively removing some of that congestion now, we're creating a more open structure before the flowers begin developing.
And that's particularly valuable inside a compact tent where four vigorous plants are sharing the same space.
โโโโโโโโโโโโโโโโโโโโโโโโ
๐ฟ Plant B โ The Girl Who Bounced Back
And then there's Plant B.
The survivor of the infamous caterpillar incident. ๐๐
Last week she had a tiny visitor arrive from the outside vegetable garden and apparently decided that one of her leaves would make an excellent snack.
Fortunately, the entire event was almost comically uneventful.
The caterpillar was found.
It was removed.
The affected area was cleaned up.
The entire tent was inspected.
And Plant B simply continued growing.
No meaningful setback.
No visible stress.
No drama.
If anything...
She seems to have responded by growing even harder.
Her foliage is now rich, healthy green from top to bottom.
The new growth is vigorous.
The branches remain strong and flexible.
And the canopy has continued expanding exactly as planned.
So I think it's safe to say:
Plant B won that battle.
The caterpillar got one meal.
Plant B got another week of growth.
I'd call that a draw. ๐
โโโโโโโโโโโโโโโโโโโโโโโโ
๐ง Drip Irrigation โ Doing Its Job
The Mars Hydro drip irrigation and automatic drainage system continues to impress me.
Each plant is currently receiving approximately 1.2 litres of nutrient solution per 24 hours, delivered consistently through the individual drippers.
The runoff is then collected and removed through the automatic drainage system.
That consistency has become particularly valuable now that the plants are getting larger and the root systems are becoming increasingly demanding.
Instead of manually trying to reproduce the same watering pattern every day, the system gives the plants a predictable routine.
And the plants are clearly responding well to it.
Healthy foliage.
Strong growth.
Stable development.
It's one of those pieces of equipment that quietly does its job in the background...
Which is exactly what I want from an irrigation system.
โโโโโโโโโโโโโโโโโโโโโโโโ
๐ฅฅ Feeding Program
The nutrient recipe remains completely unchanged this week.
There is simply no reason to interfere with something that's working.
Current feeding:
โข Plagron Hydro A โ 1.9 ml/L
โข Plagron Hydro B โ 1.9 ml/L
โข Plagron Hydro Roots โ 1 ml/L
Current EC:
1.92 mS/cm
pH:
5.8
For now, I'm keeping the nutrition exactly where it is.
The plants are showing excellent colour, vigorous growth and healthy structure.
We may increase the nutritional strength next week depending on how they respond after this defoliation and as we move into flowering.
But I prefer to make that decision based on the plants rather than simply increasing numbers because the calendar says we should.
They'll tell me when they're hungry.
โโโโโโโโโโโโโโโโโโโโโโโโ
๐ก๏ธ Blue Tent Environment
The environmental conditions remain wonderfully stable.
This week's average conditions were:
โข ๐ก๏ธ Day Temperature: 28ยฐC
โข ๐ Night Temperature: 25ยฐC
โข ๐ง Relative Humidity: 65%
โข ๐ฅฅ Substrate Temperature: 24ยฐC
โข ๐ฆ Nutrient Solution: 18ยฐC
โข โ๏ธ pH: 5.8
โข โก EC: 1.92 mS/cm
โข ๐จ COโ: approximately 450 ppm
โข ๐ก Light Schedule: 18/6
โข ๐ง Irrigation: approximately 1.2 L/plant/24h
โข ? Pot Size: 8 L
โข ๐ Plant Height: approximately 60 cm
The consistency between the four plants is one of the things I appreciate most about this project.
We're trying to remove as many environmental variables as possible so that when differences appear, we can look much more closely at the plants themselves.
And right now...
The similarities are remarkable.
โโโโโโโโโโโโโโโโโโโโโโโโ
๐ฑ Four Sisters, One Canopy
This is perhaps the strangest part of the project at the moment.
When I look across the Blue Tent from above, the four plants almost look like one giant organism.
The canopy is extremely uniform.
The colour is consistent.
The height is consistent.
The growth rate is remarkably similar.
And the SCROG has done an excellent job of bringing everything together.
Of course, if you look closely, you can still see the individual personalities.
That's why these separate diaries exist.
But from a distance?
It's becoming increasingly difficult to tell who is who.
And honestly...
That's a beautiful result.
It means the environment is doing exactly what we wanted it to do.
โโโโโโโโโโโโโโโโโโโโโโโโ
๐ฟ Plant B's Personality
Plant B continues to be one of the more naturally cooperative plants in the tent.
She's responsive to training.
She's vigorous without becoming unruly.
And she has developed an incredibly usable structure beneath the screen.
Her branches have thickened nicely, her internodal spacing remains compact, and the new growth continues appearing with that healthy, vibrant colour I've been looking for.
And perhaps most importantly...
She doesn't seem to hold grudges.
We topped her.
We bent her.
We tucked her.
A caterpillar ate her.
And now we're defoliating her.
And she's still standing there saying:
"Is that all you've got?" ๐๐ฑ
That's Plant B.
โโโโโโโโโโโโโโโโโโโโโโโโ
๐ Looking Ahead โ Flower Is Coming
After today's cleanup, the most important thing we can do is...
Nothing.
Let her recover.
Let the new growth settle.
Keep the environment stable.
Keep the roots happy.
And observe.
This is where patience becomes just as important as technique.
We've spent weeks building this plant.
Now we need to give her the time to respond.
If everything continues looking this good, the next major milestone will be the transition into flowering.
The screen is full.
The excess foliage has been cleaned up.
The structure is ready.
And the plants are healthy.
We're almost there.
Vegetative growth is coming to an end.
The next chapter is going to be very different.
๐ธ Flowering is next.
