Depends on your needs and source water. I use strictly ro/di but my tap water is liquid rock and extremely high ph. I order and change all the filters 2 times a year, so about 60-70$ just in filters. Plus you have to remineralize the water before use. But that’s one if the things I like about it. I can control what is in the water exactly.


Cost analysis required. Most RO systems waste a lot of water. When I added up the cost of a good system, water cost, and MY LABOR…It was cheaper to buy 5 gal RO from water stores. I bought water card and it reduced my cost to .16 cents a gal. 5 gal cost me .80 cents…After I had a blowout, flood, tired of crawling under sink, it is easy to see which is my best ROI

I also use RO water; I have found it easier and less costly to buy from a water store. Here about $.25/Gal.


  • Clean water, 5-10ppm from a store and 20-25ppm from smaller (9gal) system.
  • My plants get only what I give them, no guessing what might be in water.
  • I think this adds to a cleaner tasting finished product.


You must go to store and fill containers and buy.

Lessons learned:

I found out the hard way how much my plants need Calcium and Magnesium. I am adding 250 -350ppm each time I water.
