ThatsmyGrow ๐ช Gorilla Cookies Auto โ Pheno Hunt (6 Phenotypes)
Hey growmies ๐
this time Iโm doing something a bit different: Iโm starting a pheno hunt with 6x Gorilla Cookies Auto, and Iโll be documenting each plant in a separate diary to properly compare the differences.
๐ฏ Goal of this run:
Identify different phenotypes
Compare growth, structure, and flowering traits
Select the โbestโ pheno based on my criteria
What Iโll be tracking:
Growth structure (compact vs. stretchy)
Internodal spacing
Leaf structure & color
Flower development & bud structure
Resin production โ๏ธ
(Later) smell & effects
๐ Setup (same for all 6):
Same medium
Same nutrients
Same environment
โ so any differences should come down to genetics
๐ธ Iโll post regular updates with photos and try to keep everything as comparable as possible.
๐ฌ Your input is welcome:
If you notice differences or already have a favorite, drop a comment!
Letโs see which pheno performs the best ๐๐ฅ

ThatsmyGrow ๐ฑ Week 1 โ Gorilla Cookies Auto Pheno Hunt
The first week is officially done and all 6 phenos are off to a strong start ๐๐ฅ
So far the differences are still subtle, but a few plants are already showing unique traits in structure and growth speed. Thatโs exactly why I wanted to run this pheno hunt separately.
๐ Current observations:
Some phenos are growing more compact
Others are stretching a bit faster already
Leaf shapes and node spacing are starting to vary slightly
Overall healthy growth across all 6 plants ๐ฑ
Right now the goal is simple:
Build strong roots, keep conditions stable, and let the genetics show themselves naturally.
๐ Current environment:
Temperature stable at 21ยฐC
Trying to consistently maintain around 60% humidity
Light intensity adjusted for early veg
Feeding kept light for now
The next 1โ2 weeks should start revealing much more noticeable differences between the phenos ๐
๐ฌ Which pheno are you guys watching closely already?

ThatsmyGrow Week 2 is now complete and the girls are starting to show their individuality ๐๐ฅ
The environment has been very stable overall and growth has noticeably accelerated compared to the first week. Some phenos are already separating themselves from the others with clear differences in structure and development.
๐ Current observations:
Different leaf structures are becoming visible
Some phenos are showing broader fan leaves, while others stay slimmer and more sativa-like
Noticeable differences in plant size and growth speed already appearing
Overall healthy and vigorous development across all 6 phenos ๐ฑ
To improve light penetration and airflow, I also removed a few fan leaves on some plants so the lower branches can receive more direct light.
๐ก Adjustments this week:
Light intensity increased from 20% to 35%
Temperature increased to around 26ยฐC
Humidity staying between 63โ65%
Continuously trying to maintain around 1.3 kPa VPD
At this stage itโs getting really interesting to watch how each phenotype responds under the exact same conditions. The next weeks should reveal even more differences in vigor, structure, and overall expression ๐
๐ฌ Which pheno is standing out to you so far?

ThatsmyGrow ๐ฑ Week 3 โ Gorilla Cookies Auto Pheno Hunt
Another week down and the differences between the phenos are becoming more obvious every day ๐๐ฅ
The environment stayed very stable this week with temperatures, humidity, and VPD remaining consistent. Because all plants are growing under the exact same conditions, itโs really interesting to see how differently each phenotype develops genetically.
๐ Current observations:
Several phenos are already reaching close to 30 cm in height
Meanwhile, some smaller phenos โ especially Pheno #6 โ are still around 13 cm
Leaf structure and overall plant shape continue to vary a lot between phenos
Growth vigor is clearly different from plant to plant now
๐ง Feeding & maintenance:
This week the plants received their first proper feeding with around 4 liters of nutrient water.
Some phenos seem to react more sensitively to the nutrients, as a few plants are starting to show slight brown leaf tips, so Iโll keep a close eye on them over the next days ๐
I also removed more large fan leaves to improve light penetration and allow the lower branches to develop more evenly.
๐ Current environment:
Temperature stable around 26ยฐC
Humidity staying between 63โ65%
VPD maintained around 1.3 kPa
Light intensity remaining at 35%
Now Iโm really curious to see when the first flowering signs will appear ๐ธ๐ฅ
๐ฌ Which pheno would you pick so far?

ThatsmyGrow ๐ธ Week 4 โ Gorilla Cookies Auto Pheno Hunt
Week 4 has officially started and all 6 phenos have entered flowering ๐ฅ๐ธ
Really happy to see every plant transitioning into bloom now. From this point on, things should get much more interesting because the differences between the phenos are becoming impossible to ignore.
๐ Current observations:
Several phenos are stretching hard since flowering started
Some plants are already reaching heights of around 40 cm
Growth patterns are becoming much clearer between each phenotype
On the taller phenos you can already see that the first side branches are developing almost like additional main colas ๐
๐ง Feeding & training:
This week the plants received their first bloom nutrients following the Master Recipe.
I also continued removing selected large fan leaves that were shading potential flower sites to improve light penetration and help lower branches develop more evenly.
๐ Current environment:
Temperature stable around 26ยฐC
Humidity remaining between 63โ65%
VPD holding around 1.3 kPa
Light intensity unchanged
Now the exciting phase begins โ the next few weeks will probably be the most important ones to identify the strongest and most beautiful phenos in the hunt ๐๐ฅ
๐ฌ Which pheno do you think will dominate once flower production really kicks in?

ThatsmyGrow ๐ธ Week 5 โ Gorilla Cookies Auto Pheno Hunt
Another week is done and the differences between the phenos are becoming more obvious with every update ๐๐ฅ
Now that flowering is progressing, each phenotype is starting to show its own character much more clearly. Even though all plants are running under the same conditions, their reactions are very different.
๐ Current observations:
Some phenos are handling irrigation and feeding extremely well and continue pushing strong growth
Others are showing a bit more sensitivity and reacting differently to the same watering routine
Leaf size differences are becoming huge now โ some phenos are producing massive fan leaves while others stay much more compact
Plant structure and overall vigor continue to separate more week by week
At this point, 4 out of the 6 phenos are currently looking like strong candidates and fall into what Iโd personally consider the โgoodโ category so far ๐
๐ Maintenance & feeding:
Iโm still managing the canopy and keeping an eye on how each plant develops through early flower. Small adjustments and observation are becoming more important now as every pheno responds differently.
๐ Current environment:
Temperature stable around 26ยฐC
Relative humidity staying between 63โ65%
VPD maintained around 1.3 kPa
Light intensity unchanged from previous adjustments
Now Iโm especially excited to see how the buds start forming over the next weeks, because that will probably decide which phenos really stand out in the end ๐ฅ๐ธ
The structure is there โ now letโs see who delivers when it matters.
๐ฌ Which pheno do you think will end up producing the best flowers?

ThatsmyGrow ๐ธ Week 6 โ Gorilla Cookies Auto Pheno Hunt
Another week is in the books and the differences between the phenos are becoming impossible to ignore now ๐๐ฅ
Stretch has been very different across the plants and some phenos are clearly showing completely different growth patterns despite running under the same conditions. Itโs getting easier every week to identify which phenos stay compact and bushy and which ones want to reach for the sky.
๐ Current observations:
Pheno #3 and #4 have stretched aggressively and are now above 70 cm
Pheno #5 took the lead and is currently sitting at around 101 cm ๐๐ฅ
Pheno #1 and #6 are still in early flower / preflower and developing noticeably slower
Plant architecture is becoming very clear now โ some phenos are growing dense and bushy while others are showing strong vertical growth
At this stage I already have clear favorites:
โญ Pheno #4 and #5 are currently standing out the most for me in terms of structure, vigor, and overall development. But the real decision will come once the flowers fully build up.
๐ Maintenance & development:
Canopy management continues and Iโm still removing leaves only where necessary to improve light penetration and keep flower sites exposed.
๐ Current environment:
Temperature stable around 26ยฐC
Relative humidity sitting around 67โ70%
VPD target remains unchanged and is being monitored continuously
Light intensity continues to increase gradually as flowering progresses
The next weeks should become really exciting โ structure is one thing, but now the buds will decide who becomes the real winner of this pheno hunt ๐ธ๐ฅ
๐ฌ Which pheno would you bet on at this point?
