When I make up fert. solutions I use measuring spoons which are fractions
of a teaspoon. I don't have a scale. If it's not too much trouble, I wonder
if someone knows how many mg's of Boron are in say, 1/8 th teaspoon (or some
other fraction of a teaspoon) of Boric Acid Powder? I need to make a
solution of known concentration.
Thanks!
