Hydro-gardens Chemgro
4-18-38 use 8 ounces (dry weight)
Calcium nitrate 8 ounces
Epsom salt (magnesium sulfate) 4 ounces
When using on mature plants, per the instructions, you would use these rates to make 100 gallons of solution.
I then pump this solution through a 1/2 poly line that has tubes tapped into it that go to spray stakes. They spray the solution onto the top of the soil in the bag long enough to get just a tad to trickle out the bottom of the bag. This gets repeated 6-8 times per day.
