Fish Amino Acids
Learn how to make FAA, a KNF fish amino acid input made from fish scraps and brown sugar. This module covers clean fish selection, the 1:1 sugar ratio, breathable long fermentation, aroma checks, straining, storage, and safe diluted use.
What is FAA?
FAA stands for Fish Amino Acids. It is a KNF input made by fermenting fish scraps with brown sugar so the fish breaks down into a concentrated nitrogen-rich liquid.
FAA starts with clean fish scraps or small fish mixed with brown sugar in a clean container. The sugar pulls liquid from the fish and helps preserve the ferment while microbes slowly break it down.
The container is covered with cloth, paper, or a loose breathable lid, not sealed airtight. This protects the ferment while allowing gas to escape safely.
In simple language: you preserve fish with brown sugar, let it slowly ferment, then strain and store the dark amino-rich liquid for diluted plant use.
Success depends on clean fish, correct 1:1 weighing, enough sugar cover, patient fermentation, good smell, no foul rot, and conservative dilution.
Clean fish material
Use clean fish scraps, small whole fish, or fish frames. Avoid spoiled fish, cooked fish, salted fish, and heavily oily leftovers.
1:1 by weight
Use equal weight fish and brown sugar. Example: 500 g fish with 500 g brown sugar.
Breathable cover
The ferment should breathe. Never lock an active ferment under pressure.
Dilute, do not blast
FAA is concentrated and nitrogen-rich. Start low, observe the plant, and avoid heavy use in flowering.
What you need
Keep it basic: clean fish material, brown sugar, a clean jar or bucket, a weight or sugar cap, breathable cover, and a label.
Fish material
Use clean raw fish scraps, frames, heads, or small fish. Avoid spoiled, cooked, salted, or seasoned fish.
Brown sugar
Use the same weight as the fish. Sugar extracts liquid, controls smell, and helps preserve the ferment.
Clean jar
A clean wide-mouth jar or bucket makes mixing, pressing, and straining easier.
Weight or sugar cap
Keep fish covered with sugar syrup or a sugar cap so the surface is protected from bad rot.
Label
Write the plant, ratio, and start date so the batch stays easy to track.
