I'd like to hear from the experts with experience on using MSU. I got my shipment of MSU in yesterday and expect my counter-top RO unit to arrive next week. Until then I've got a choice of either continuing to buy distilled water as I have been or just going back to using my local tap water which 1)has a pH of 7.8->8.3 and 2)is very hard. Here is the 2014 water quality report link. It doesn't mean much to me but maybe to someone here it may mean whether I can use my tap water for one fertilizing cycle or I should use distilled water - http://www.copperascovetx.gov/pages/...lityReport.PDF
