Hi Gk, do you mean you went to y618 to buy SEACHEM Pottasium and was recommended to buy Pottasium Sulphate in dry fert form right?
if i understand correctly from you then the answer is yes... you can dose using the dry fert form and its cheaper in long run. But normally i use EI formulation and online calculator to calculate the neccessary dilution before adding into tank.
well you can google EI for more information...or go to my blog to see the article about EI dosing....
