    I've been using GH ph up to raise water ph, but I'm currently trying a 100% organic grow.
    Can anyone recommed an organic (and obviously safe for the plants) way to raise water ph?
    Would baking soda work or is that too much sodium? Thanks in advance.

    You can use lime or any other natural alkalines at your local grow shop. I would highly recommend against the baking soda. I am doing an experiment in my horticulture class on the effects of pH, and we are using baking soda along with pH up. The plants HATE the baking soda, basically we are doing a controlled kill with it. The plants hate the baking soda, and it affects the way the plants take up nutrients.

    Also NO to the baking soda.

    Earth Juice makes organic pH up and down.

    It can be used in smaller amounts, but there are too many more viable alternatives. Too much baking soda will increase the salinity of the soil, and disrupt a plants ability to absorb water and nutrients.
    I use dolomite lime mostly. You can mix it in water, it just isn't going to dissolve entirely so you have to keep it agitated.
