PPM Fertilizer Calculations
_Jack's Nutrients 12-4-16 RO
mg of fertilizer = target ppm (mg L) / % of desire element in compound
= mg of fertilizer in 1 liter of water to supply target ppm
Divide by 1000 twice to get grams of fertilizer per ml of water.
- 50 ppm N

- 470 ml Water
50 / .12 / 1000 / 1000 * 470- 0.196 g nutrient
- 100 ppm N

- 1700 ml Water
100 / .12 / 1000 / 1000 * 1700- 1.417 g of nutrient

Hydrogen Peroxide
A spray bottle of Dawn PowerWash gives out exactly 1 ml of hydrogen peroxide per full-spray.
If you use an undiluted 35% hydrogen peroxide, the recommended dose would be 2-3 Milliliter for each gallon of water.
With 3% hydrogen peroxide at your disposal, you should begin by adding 3 milliliters per liter or 2-3 teaspoons per gallon of reservoir water.
