Does anyone use rainwater? Ive been using it for months. I thought it was a true reverse osmoisis with a nuetral PH. I just found out that since the rain absorbs carbon dioxide from the atmosphere it averages a PH of more like 5.5 - 6.0....Im using hempy buckets. I dont have any meters to check anything. Should i add a little dolomite lime to the water?
