Recently I read something that brings up another question about using distilled water. I read that using a "regular" orchid fertilizer in rain water or RO water can burn your orchids. Is this true for distilled water as well?

If so, how much should I dillute my "regular" orchid fertilizer so that I can use it in distilled water? The package says to use 1 teaspoon of fertilizer per gallon with every watering.

Thanks! Dana
