    water quality

    Whats the highest total ppm that you can use on neps? I've always just bought RO water, but I just got a water report from the city, and it would save me a lot of money/time if I could just use tap water.

    I heard less then 100 ppm (mg/L) is ok. Mine is 39ppm, according to my EBMUD water report. ^^ Probably should get it tested later this year tho..., cause we are having a bit of a drought...

    Looking at this report, I'm coming to realize my water has a bunch of tasty additives....ammonia, chloride, barium, ARSENIC, LEAD, CLOROFORM, sulfate, etc
    I need to move.

    I just looked at the most recent Lubbock water report - http://water.ci.lubbock.tx.us/documents/2006%20WQR.pdf - and I now have much more appreciation for our water here. I was going to suggest alternating tap water and RO but, after looking at what comes out of your tap, I wouldn't. Is there enough humidity there for ACs to drip much water or for people to have basement dehumidifiers? Those can be good sources of distilled water.

    I'm lucky here in southern maine.
    I just tested my water and it's 37ppm.
    I still use a R/O unit for all my drinking and plant water though.
    phissionkorps, people at the nep forum might know the answer better, but with the flushing neps get evry time they get watered, your water should in theory be okay. I only paid $100 for a complete 100gpd R/O unit with tank. I would rather be safe than have some picky plant not grow well for me, or worse die from the build up of minerals and salts.
