  1. Hi guys Im about to start growing in my 70/30 coco/perlite mix and wondering what water to use. I’ve read a lot about RO water but is it really needed? I’ve noticed it’s pretty expensive and I’ll be draining to waste. These are my water results from home can I use these?
    My water at home (Australia)

    Straight out of the tap
    Ph 7.5-7.8 ppm 90-95ppm

    Water I filter using a still spirits carbon filter i used when homebrewing
    Ph 7.6-7.9 45-49ppm

    And rain water in tank caught off shed roof
    Ph 7.8-8.0 ppm 15-18ppm

  2. Your tap water will be fine - r/o is an unnecessary expense. Good luck.
