I bought mine at a hydro store for $150. I hear they are even less expensive on e-bay. We have a well and I am 100% sold on RO water for my hydro system after finding out the hard way trying to keep ph stable etc. Worth every penny.
Weedhound Reviewed by Weedhound on . Good way to Get R/O Water?.. As I learn more and more. I have heard about how good R/O water can be. When I look up RO water on the internet I see these big machines (filters) that cost thousands of dollars to make RO water. Are there any cheeper solutions to getting R/O water like I guess buying it or a home version of the R/o Filter? just curious, about this R/O Water. Zandor preaches about it in the Grow reports. thansk kd Rating: 5
