Distilled vs. Spring

[boytjie]

My tap water is leaving mineral deposits on plants and roots, and some roots are dying, despite regular flushing-out of pots. I'm looking at alternatives. I have a smallish collection (around 50 plants), so I think I can handle the expense of bottled water from the supermarket. Anybody out there who could give a short summary of the differences and benefits/shortfalls of using distilled water, vs. spring water? Thanks!
