yan420 🐟💀 FERMAKOR: The Dorade Incident – Spontaneous Batch Log
(Because the fish came with guts, and I don’t waste potential)
---
🍽️ How It Started
I ordered two big Dorades for dinner. Didn’t bother ticking the “cleaned” box.
They arrived whole — full organs, eyes staring, one of them with a stomach packed with broken seashells (free CaCO₃ bonus).
So instead of complaining, I just said:
“Alright, fine. Dinner first. Hydrolysis later.”
---
⚗️ Phase 1 — The Gut Start (Day 1)
Material: 160 g of fresh guts straight from the fish.
KOH: 20 g (yep, strong ratio, I know).
Water: ~250 mL warm.
Dissolved KOH → poured over → stirred → left to liquefy.
Within minutes it warmed up and foamed; by evening it was already turning into that deep brown, oil-slick mix I like.
---
Phase 2 — The Rest Goes In (Day 2)
After dinner, all the remaining parts go into the same container:
Heads, bones, fins, skin — roughly 500–600 g.
Add another 30–35 g KOH and ~0.5 L water.
Stir and let it digest for a week or two or three, until smooth.
The seashells stay in — they buffer the pH and slowly release Ca and trace minerals.
---
⚖️ Phase 3 — Neutralization
Once the mix settles, I’ll neutralize down to pH 6.2–6.4 using phosphoric acid.
Target ~40 mL of 59 % H₃PO₄ for the whole thing.
Then strain through cheesecloth / pillowcase (no coffee filter — that’s only for exports 😎).

yan420 11.11.25 — Dorate Extraction
Added 40 g extra KOH.
Reaction had slowed and odor developed — a clear sign of incomplete hydrolysis.
Solution stayed pale, meaning both temperature and KOH strength were too low.
Might switch to nitric acid for neutralization next time to provide nitrate-N and avoid the mild phosphoric/citric buffer limitation.
---
12.11.25 — Continued Breakdown
The reaction slowed again after adding the cannabis leaves, releasing more odor than expected.
To finish the process, I added 31.2 g of potassium hydroxide to balance the new biomass and restore proper alkalinity.
The mix has already started to darken again, and the smell is dropping fast.
This should push the hydrolysis toward completion.
Next step is pH testing — if it’s in range, I’ll let it settle before starting the neutralization phase.

Was going to close the diary today but as it doesn't smell anymore I decided to close the diary this coming Tuesday, smell shifted from chemical fish ammonia to cooked fish with the additional Citric acid I sprayed in, rest in video 📸

Today I’m closing the Dorade extraction.
This batch has been breaking down for about two weeks, and now it’s ready for the final steps: blend, neutralise, filter, bottle — done.
I’m using a light citric-acid adjustment to kill the smell and stabilise the concentrate before storage.
Then it goes through the sieves, gets a final squeeze, and straight into bottles.
This isn’t a recipe — just my normal cleanup routine once an extraction is fully digested:
• break down the leftover solids
• bring the pH down into a safe acidic range
• filter everything clean
• bottle and store
Two weeks of rot, one day of work, another homemade input finished. On to the next one.

@THcHunteR23, Thank you🙏, I'm hoping to use this one as an add on to the PK Micro version I'm already using so I'll have two distinct bottles FERMAKOR N(PK)+Micros and FERMAKOR PK(N)+micros, it works bro, already tested the PK version, next step is to try it from seed to harvest.
✌️❤️
@Hattiwatti, It already works bro, it's just an add on that I will blend with my main FERMAKOR PK Micro nutrient mix fo a bit extra N and micros, test plant is already thriving, thanks for dropping by growmie 🙏♥️✌️
@TrickzGrowz, Lol bro, it doesn't smell much anymore, the procces turns the smell in a different direction once it's all soaked, first two to 4 days it's more of a chemical ammonia smell after that it Drifts towards soya/fish sauce smell earthy etc etc, of course the chemical "touch" is still there.
Have a good one and if you have any questions feel free to ask ✌️ ♥️
@TrickzGrowz, Dann hast du wirklich keine Ahnung wie "dein" Dünger hergestellt wird lmfao, wie gesagt wenn du Fragen oder was beitragen kannst mach es einfach aber für solche "Diskussionen" habe ich nicht viel Bock ✌️♥️
looking good brother always love to see diaries that are growing with own created nutrients 💚 i wish you the best and i will definitely keep a eye on this diary !
@MonyetDiablero, Thank you bro, it is fun to play with lol, but it will be the last time using fish lol, even though they're are ways of putting the smell down one small mistake and yeah lmfao, there are less smelly organic N sources, I'll be going with beans next time 🤞❤️✌️
@MisterZ, It will work bro, the other versions I have running are all spot on for what I'm using them for, it's basically the same but more concentrated version of the 15-20€ bottle fish emulsions "we" growers throw money on lol, see you around bro and if you would like to try send me a DM ✌️♥️
@Green_claws, Nah bro they didn't dissolve, not completely at least, the soft parts were completely gone though, and neither did the cannabis leafs and branches I put in a bit later, it was probably not caustic enough anymore even though I added some extra Koh at some point, I'll be testing on my next grow, once the tent is empty✌️♥️
@yan420, ye get ya so the thin boney bits did, so what then A bit more time and they would you think?. Keep these ferment diaries going dude I proper geek out on this stuff.. ✌️💚
@Green_claws, Exactly bro, the thin and soft stuff goes first, the tougher bone material needs either more time or a stronger caustic environment from the start.
If I’d kept it hot and topped up the KOH earlier it probably would’ve gone further, but this batch slowed down once the causticity dropped.
Next run I’ll push it harder from day one and see how far I can take it. Appreciate the love man, I’ll keep the ferment diaries coming ✌️💚
Ps I think acids are more efficient for breaking down bones into calcium etc etc
