been doing a little reading this morning, came across some info about urea as an N source in ferts. seems there is some debate about it, studies, urea-free as a sales pitch, etc.

i've noticed here that the fish emulsion ferts are in demand.

anyone feel like giving their views?

since i'm someone who is prone to over-nuturing, and i've read that it's harder to over-fertilize with the fish emulsion or seaweed ferts, i'll probably go with those - but that's because of me, not the urea content.

also, somewhat related; would the source of acid to create a low pH make any difference? say, diluted cider vinegar or diluted formic acid....

just curious
