Foli-Cal 10% Calcium Concentrate 1 pint ..................................... $9.95
Excellent for adding Calcium with out adding any Nitrogen.

Foli-Cal is a brand name of 100% soluble Calcium acetate.

NOTE: Very Strong!

we DO NOT recommend using the full label application rate.
For reference each milliliter (ml) of concentrate will add 150PPM per gallon of

normal rate we recommend.
