So, I bought a TDS meter to test our tap water, and the total dissolved solids reading is 20 ppm. I look at Greenville, SC's water quality report, and the latest seems to indicate an average of 44 ppm (see attached screenshot)

. Are these low enough not to require that I use distilled water for my VFTs and other CPs? Any other numbers on the attached photo bothersome for VFTs and other CPs?

Thanks!

Forrest

That's about the same as mine. Seems to work fine, though it wouldn't hurt to clean your trays out occasionally.

20 ppm should be fine. I believe the standard guideline is that up to 50 ppm is ok. But like nimbulan, I would flush things out a few times a year with distilled water just in case.

Well I don't because it would be a huge pain but it's usually recommended. It doesn't seem to cause any problems for me.
