Some experienced Paph growers claim that the plants growing on limestaone aren't in contact with the limestone, but are in the leaf mold between the rocks, and therefore are not growing in a high PH, but in a low PH. Haven't tried experimenting yet to see if they are right, but have started raising my fertilizer solution to about PH of 9 to compensate for my low PH mix of about 5.2 or less. The first run off is about 6.5, so it looks like this is going to work. Cynthia, Prescott, AZ
