    Thanks for the explanation. I've also heard this from other CP seller,youtube, and blogger. Though your explanation is the most thorough.

    Can I use the remaining water to do anything else?

    I have a flood/drain setup-up with various plants (CPs, non-CPs, few Neps) where I pump the water weekly (RO water with ferts added to about 100 ppm) to the tops of the pots then allow the plants to sit in that water for about 30-60m before draining the tank back down. I reuse this water for about 4-6 weeks before remixing another batch.

    I can not recall which ones but a few of the fert components are long gone after the first day but I've seen no real world problems yet.

    Just a word of caution, if you have an issue with one setup (insects for instance) and reuse that water in another setup that can be really bad. Or invasion CPs, think Utricularia or some of the Droseras.

    if you asked if it would be beneficial, then the answer would be yes.

    Av8tor1's hypothesis, is just some of what my sophomore year, Soils 252 professor, taught us in that class, plus tons more similar information.

    When watering/leeching CP pots, and recycling the water; my first concern, as RSS has mentioned, is the potential of transferring pests and diseases; second is to always be 100% certain that the TDS (total dissolved solids) of the water, always remains low enough that it is not harmful to CP.

    Did your professor have trial results? I'm reminded that the 'learned' ones also used to insist that the world was flat

    I'll take it that the answer is a no then.

    Well, we actually had many different, "labs", where they had us perform experiments to demonstrate many of these hypothesis. That was almost thirty years ago, and I can't remember all of the details.

    Here's a link to such research -> Link.
