Welcome to Part 2!
In Part 1 we learned the most important thing:
my phosphoric acid is way stronger than my KOH stock,
which is why 4 parts KOH and 1 part acid gives a perfect 1:1 PK.
Now in Part 2, I’m showing you the simple growmie method to create ANY PK ratio you want — without complicated math, no chemistry lessons, and no headaches.
Just real-world logic you can use immediately.
The only rule you need to remember is this:
In my setup, the acid is about 4× stronger.
Once you know that, everything becomes easy:
Want more potassium? Use more KOH stock.
Want more phosphorus? Use more acid.
PK 1:1 → 4:1
PK 2:1 → ~2:1
PK 3:1 → ~1.5:1
PK 1:2 → flip it
It’s simple, clean, and growmie-friendly.
This is the system I use to build my FERMAKOR PK mixes for bloom, transition, and veg support — and it works perfectly in real grows.
Part 3 will show the actual PK recipes I use and how I scale them into bottles for full grow cycles.
We grow together, growmies 🌱🔥
