I use a few inputs, OHN, FPE/FPJ, FAA, LABS, and IMOs
Um I would say it's a bit of work, and probably unnecessary for me at this point as I'm using amended soil and feeding at fairly low dosages. (Other than the OHN as I feel like that has benefited the health of my plants quite a bit and it seems to be pretty good for pest management.)
I like to supplement with LABS as well as other beneficial bacteria (https://themodern.farm/why/)
I guess mostly it's just fun. I try and forage for or grow most of the things I use in the FPE and FPJs or get it from friends or farmers markets and watching things ferment is just another bonus.
