For constant feeding and hydroponic systems, the range in common nutrients solutions is 0.01-0.1 ppm copper.
To make a concentrated liquid stock solution. Add 0.15 grams to one liter final volume water. Then use this stock solution at 1 mL-10mL per gallon of working strength solution. This use rate(1-10mL/gallon) gives 0.01 to 0.1 ppm copper in the working solution.
When this product is used as a feed or fertilizer ingredient:

DANGER - PELIGRO
If the Bordeaux mixture instructions read 10-10-100, the first figure indicates the number of lbs of Copper Sulfate Crystals. The second figure is the lbs of hydrated spray lime and the third figure is the gallons of water to be used. Use as a full coverage spray to point of runoff.
Fill a tank 1/4 full with water. Then, with agitator running, mix in Copper Sulfate Crystals through a copper, bronze, stainless steel or plastic screen. Add water so the tank is 3/4 full. Mix in the hydrated spray lime through the screen and finish filling the tank with water.
