I use ferments as additives to
compost, I don't use them directly on plants,
it is a personal preference that is based on removal of ciliates and other parasitic organisms that can be found in anaerobic preparations.
If I was to use a ferment directly on plants I would first aerate it for around 24 hours to limit the numbers of parasitic and detrimental organisms present in the solution.
I would also probably dilute it at least 1:1
