  1. I BOUGHT SOME OYSYER SHELLS BUT NOT SURE HOW MUCH TO MIX IN A 4gallon bucket...this stuff is powdered...i took a picture of the oyster shell indtructions for mixing it with potting soil...it says use 1/4 to 1/2 pound per cubic feet....SHOULD I USE THE DIRECTIONS FOR HOUSE PLANTS OR POTTING SOILS?
