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

Thx

Paul

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.

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.

paul.
