in reality you dont need a PPM/EC/TDS meter. yes they are nice however if you use the bottles directions you will be damn near perfect. The downside is that you cant monitor the solution thruout the week. I did my 1st grow w/o a meter and it went just fine. After you get your feet wet and learn the different strains characteristics you will want to tweek your grow for an even better finish. Some strains need more nutes...some less..
No matter what you need a PH meter
