I have send this message before, but didn't see it arrive on the list. So, I
will try it again.
I agree on that, but I did not mean/mention the PH change caused by acid
rain, but the deposition of nutrients (especially nitrogen oxides). The
nutrient input by rain has caused formerly nutrient-poor ecosystems with a
high diversity of species to become monocultures.
>However, I also think that this problem of rain water will not arise in a
collection of cp plants. Since in nature the biggest problem of the higher
nutrient availability will be the increasing dominance of other more common
species and these species are not present in a collection. So, I think that
most rain water is appropriate for watering your cp's, I only did not agree
with the reasoning of Tom.
