    Could somebody please advise what the difference is between K2PO4 & KH2PO4 if any or is it how people would abreviate it.

    Thx

    K2PO4 - Potassium Phosphate
    KH2PO4 - Potassium dihydrogen Phosphate

    Any form of soluble PO4 is ok to use (Most of the K comes from KNO3 anyway). It is just that KH2PO4 is more readily available.

    Thx Arron

    Its just that I have been given a bag of K2po4 and i was wondering if I could mix it with my KH2po4 - are they the same thing.

    Regards

    It will be fine, both compunds are mixed the same way anyway (15g to 500ml of water and adding 5ml per 100L of water to give 1ppm) so it wouldn't matter if you dosed one slightly more than the other.

    perhaps i should have said - can I add my K2po4 to my KH2po4 making one lot of ingredients (dry ferts) ie mix them both together.

    regards
