Using Low‑PPM Well Water for Carnivorous Plants

When Well Water Is Good Enough

A well water reading of ~50 ppm TDS is excellent for most carnivorous plants. It’s far better than typical tap water (200–400 ppm).

Top‑water frequently to flush accumulating minerals.
Monitor Venus flytraps—they’re the most sensitive. Switch them to RO if they show decline.
Expect slower mineral buildup than with higher‑TDS water, but it will happen over months/years.

If you already use 10+ gallons daily, this saves an RO system. Test TDS quarterly.
