yan402 FERMAKOR BARREL MIX – BASE IN USE
(Testing on the Fantasy Feast girl we pulled out of another diary

(FERMAKOR BASE SYSTEM KOH VERSION diary

(Urea & Micros on the way — first week running without them)
🍶💧🍶💧🍶💧🍶💧🍶
💧 30 L Barrel – Current Working Mix
🍶💧🍶💧🍶💧🍶💧🍶
Step 1 – Calcium Nitrate (Part A)
7 L warm water (~35–40 °C) → added 45 g Calcinit, stirred until fully clear.
That’s the calcium + nitrogen backbone for the feed.
Step 2 – FERMAKOR PK Base (Part B)
15 L water in the main barrel → added 30 ml FERMAKOR PK Concentrate, mixed well.
This forms the main P + K part of the formula.
Step 3 – Combine Solutions
Slowly poured the Calcinit mix into the barrel while stirring — no reaction, still crystal clear.
That confirms the mix is stable and precipitation-free.
🌿 Step 4 – FPJ / FFJ Batch
Added 30 ml homemade FPJ (fish + veg batch) ≈ 1 ml/L.
Color shifted to a light-amber tone — looks alive and active.
🍋 Step 5 – Citric Acid Balance
Added 1 tsp citric acid after everything was blended to fine-tune pH and help chelate micros later on.
📦 Step 6 – Top Up & Check
Filled to the 30 L mark with plain water → pH tested with drops, showing yellow-green — roughly 5.8 – 6.0 range.
Nice clean look, stable smell, no residue.
🧠 Current Status
First day feeding the Fantasy Feast girl with this base mix.
Too early to tell how she’ll react, but so far everything looks clean and balanced.
Ca + N from Calcinit and P + K from FERMAKOR should be plenty for a gentle start.
Citric + FPJ round it off nicely.
We’ll see how she takes it over the next few days before deciding if she even needs the urea and micros.
💧 Current Base Ingredients (Active Mix)
Warm Water ≈ 22 L total
Calcinit 45 g → N + Ca foundation
FERMAKOR PK Base 30 ml → P + K support
Citric Acid 1 tsp → Chelation + pH balance
FPJ / Fish Emulsion 30 ml → Organic enzyme booster
Result: clean amber mix, mild and balanced.
I’ll let this version run for a week before adding anything.

💧 Nutrients in 30 L #1 (Veg Strength)
🍶💧🍶💧🍶💧🍶💧🍶
💧 Calcium Nitrate (Calcinit / Nitcal): 45 g
= 1.50 g/L → ≈ 225 ppm N + 150 ppm Ca
🍶 PK Concentrate (FERMAKOR Base): 30 ml
= 1.00 ml/L → balanced 1 : 1 P : K support
💧 Home-made FFJ / FPJ (Fish + Veg Batch): 30 ml
= 1.00 ml/L
🍶 Citric Acid (Chelation & pH Balance): 1 tsp (max)
= 0.33 tsp/L → add only after checking pH
💧 Target pH: ≈ 5.8 – 6.0 (drop test – yellow-green zone)
📦 TOTAL: ≈ 105 ml / 45 g inputs per 30 L (≈ 3.5 ml / g per L active mix)

@tantrumrage, Not sure in this case to be honest with you as I'm doing it for a first time with this ingredients, but I whip it up every day so no air stone, my usual mix holds for a week max in the summer, it's usually empty before it spoils with 2-4 plants, winter a a couple of days longer, I'm going to have to try out and keep notes I guess. ✌️♥️
