Vinegar dilution
What is the dilution ratio for knf vinegar?
also do we need to store the finished vinegar in a breathable lid?
thank you
Top answer
Dilution for plants is typically 1:500 for most applications.
I store the vinegar with a sealed lid to prevent evaporation and bugs, but it could be stored with a breathable lid.

Drake's library gives 1:500 for banana vinegar on plants. (Student's Manual, Basic Course, p. 41) For brown rice vinegar used as a cleanser, it gives 1:500 on juvenile leaves and 1:200 to 1:300 on adult leaves. (Office Hours Ep. 66, 1:08:33) One office hours answer gives brown rice vinegar mineral solution at 200 to 1, which is stronger. (Office Hours Nov 2025, 55:48) The sources differ, so match the ratio to the use.
On lids, the library splits two stages.
- While it ferments, vinegar sits in a container filled two-thirds full with a breathable lid. (Office Hours Mar 2025, 35:44)
- Finished KNF solutions go under an airtight lid once they are super-saturated. (Office Hours Ep. 26, 22:50)
- The manual says to store banana vinegar in a dry, cool place, away from direct sunlight. (Student's Manual, Basic Course, p. 41)
The library does not say outright whether finished vinegar needs a breathable lid. The airtight-lid answer speaks of solutions in general, not vinegar by name.
