Does MSU Fertilizer have to be used with Reverse Osmosis (RO) water?
• No. MSU RO/Rain/Tap Water Version Fertilizer is good with any water that is low in alkalinity such as most tap water, rain water and reverse osmosis (RO) water. • MSU Well Water Version Fertilizer is good for hard water from wells. • Water that is extremely high in alkalinity or tastes salty isn’t suitable for watering orchids no matter what fertilizer you use. Households in areas where the water is unsuitable for orchids should consider solutions such as rain barrels or filters.
