️ FERMAKOR – Neutralisation & Filtering (Final Stage)
“From reactor to bottle — the first real batch.”
---
18.10.25 — Pulled about 1L of the finished FERMAKOR extract into a 5L bucket and added roughly 2L of clean water. Let it sit for a bit to calm down and cool off before touching the pH.
Sample came back around pH 6.8–7, totally non-caustic — exactly what I wanted before acidifying for storage.
Started adding phosphoric acid (59%) slow and steady, stirring between each pour.
Ended up using about 50ml total before the colour flipped red on the GHE drops, landing the mix right around pH 3–3.5.
No foam, no violent reaction, just smooth. Smell turned clean and metallic-sweet

Filtering setup
Used a pillowcase and cheesecloth layered together as the filter stack.
It came out thick, dark amber, glossy — zero grit.
I’ll leave it to rest overnight, open, just to let any tiny bubbles or gases clear out before bottling.

Final note
This batch is officially FERMAKOR B Concentrate V1.0 (1:4).
Storage pH locked between 3.3–3.8, ready to bottle and shake before use.
This one should be rich in P, K, Mg, and micros, while Calcium Nitrate will handle the N and Ca on the A-part side.

Closing the diary
That’s it for this round — extraction phase complete.
I’ll be closing this diary here and opening a new one called “FERMAKOR A+B Test Grow – V1.”
Testing starts tomorrow on a single plant.
Time to see if this brew actually works in the tent.
All images videos to be added later — filter setup, pH colour, and final concentrate.
