CALCULATORS FOR HYDROPONIC GROWERS

 

PPM IN SOLUTION CALCULATOR



When you purchase a liquid hydroponic fertilizer it comes in concentrated form. You then dilute this fertilizer with water and this (water + fertilizer) is then fed to plants (as ‘feed solution’). I.e. Fertilizer + water = feed solution. For instance, you may add the nutrient at 5mL/L to create your feed solution. The ‘ppm in Solution’ calculator equates the ppm of each and every element that is present in feed solution after a fertilizer concentrate is diluted at a given ml/L usage rate. You will also find  ppm to %w/v, %w/v to ppm, K2O to K, and P205 to P conversion calculators on this page.

 

DILUTION CONCENTRATION CALCULATOR



The dilution concentration calculator is used to establish the quantity of solute that is required to achieve a desired/optimal ppm or %w/v in solution. Use this calculator to establish how many grams of solute is required in a given amount of litres to achieve optimal ppm in solution.The dilution concentration calculator also allows you to convert gallons to litres.

 

CHEMICAL FORMULA AND MOLE CALCULATOR



The chemical formula and mole calculator is particularly helpful for establishing the percentage of each element that exists in a fertilizer or other chemical product. It is also helpful when working with formulas expressed in mole (e.g. pH and EC Standards). Simply enter the chemical formula and its purity and the calculator does the rest.

 

GRAMS OF FERTILIZER REQUIRED IN 10 LITRES TO ACHIEVE TARGET ppm IN SOLUTION CALCULATOR  (New!)



The ‘grams of fertilizer required in 10 litres to achieve target ppm in solution calculator’ is used to establish how much of a dry/powder/solid agricultural/nutrient base fertilizer is required to be added to 10 litres of hydroponic nutrient solution to achieve a given ppm in solution of any nutrient species. The calculator is extremely handy for working out e.g. how to add a sort after ppm of Cal-Mag or P and K to solution using dry/powder/solid fertilizers.

 

All you have to do when using this calculator is enter your fertilizer nutrient percentages, enter the sort after ppm you require and hit calculate. The calculator then tells you how many grams per 10 litres are required of your fertilizer to achieve your sort after ppm in solution. The calculator also tells you what ppm of any other nutrient species you have added to solution where working with fertilizers that contain two or more nutrient salts.
