I am considering creating a minibog in an area that is swamplike around the streamlet running behind our home as well as seeing if the water is safe to use directly on CP's. Mind you, I work in a lab and get alll the free deionized water I need. I keep nearly all of my plants at work for this reason.
I just had the water tested for Ca, Mg, K, and Na. The results are in PPM. Does anybody know the detection limits acceptable for CP's (in general)?
I am also having the water tested for dissolved solids.
