    Water quality/hard water

    I have been preparing for my first grow and I have tested my tap water a few times over last week and am a bit confused. First test it ph was 7.2 and ppm was 55. Tested today and it's 7.7 and 160 ppm....is it common/normal for water to change that much? Is 160 ppm 'hard' water? I'm in question because I thought I could just add ph down on the 7.2 first test and it would stay at same levels needed. Am I going to need to filter this somehow?

    Na, you have great water quality. Water changes with environment. Yes, fluctuations like this mentioned above are fairly common.
    “Hard water” is full of calcium... plants love calcium as long as it’s not causing a lock out situation. Judging from your ppm, you will be fine to use tap water.

      ty for quick reply, will just watch it and use ph - to get to 6.5, not going to worry about filter then, growing in coco

      For hydro you really want to ph to range between 5.5 and 6.5. You should be hitting the upper, mid, and lower portion to absorb all the nutrients required for a healthy plant. Hitting the same 6.5 will lock out nutrients that get absorbed at 5.5.

    Our water is 500ppm. Crazy... and I don’t use RO filter. You should be fine

      Budler, You have 'soft' water, here, ours runs from 695-864 ppm (as per the city's annual water quality report) and works very well for my plants and myself (strong bones, healthy plants! LOL), and I don't need to buy any mineral supplements!
