Which reminded me of a question:  Can a chemist out there
explain the difference between NaH2CO3 and NaHCO3, both of
which are given as the 'chemical formula' for 'Sodium
Bicarbonate?'  I mean besides one formula name having
dropped an "H".

Whichever is correct, you can't get this more cheaply and
easily than buying baking soda.

BTW, I too have found Litemanu.com to be a reliable source
of chems that work on plants (Mono-Potassium Phosphate
$4.20/lb, Potassium Nitrate-$2.35/lb, and Potassium
Sulfate-$5/lb).  The minimal shipping costs can easily
exceed the materials cost, and a pound lasts a long time.

select "Chemicals", then page down to your choice(s) of
