I would personally use distilled/RO water. It is nice to know exactly what is in your water, no guessing. I used to use 350 PPM tap water and I think my plants grow a lot better and easier with the RO water. You will have to use CalMag but I bought a bottle of it about 3 months ago and its not even half gone, you only use 1 tsp per gallon.
dejayou30 Reviewed by dejayou30 on . Nursery Water? I was at Wal-Mart today and was wondering what the difference between Nursery water, Drinking water, and Spring water is, and what I should use rather than my buddies city water, which is pretty gross and hard as shit. It said the NUrsery water was steam distilled. The spring I didnt actually read, its sort of self explainatory. And the drinking water said it was filtered. What should I use. I have botanicare pro grow blend and am using a 5 gallon DWC. I think my buddies water might be a buzz Rating: 5
