I am looking for ways that are not harmful to orchids to lower my ph to around 5.7.I am getting a ''ph pen'' and trying to figure out how to analyse water breakdowns giving by my state agriculture dept. such as what is acceptible for orchids.Knowing that is a rather broad question because of the variety of orchids,is there a book that could be helpful? I am growing a large variety from cattlyas,phalaenopsis,gongorias,paphs.phrags,oncidiums etc.thanks for any suggestions-Lee
