Do any of you collect rainwater to use on your orchids? I want to
collect the rainwater off of the roof of my house. I had to get a new
roof after last summers hurricanes so I have new asphalt shingles and I
am wondering if there is anything toxic in them. Not that a TDS meter
can tell me anything, but the TDS of the rain from my roof is the same
as the rain falling right into a clean bucket.
