A newby question on terms used in fertilizers: What does the three numbers listed in ferts label refer to?

Eg. Seachem's Flourish Nitrogen has the following three number listed: "1-0-2" while Phosphorus list the following: " 0-0.3-0.2" and Potassium list two zeros and then one value: "0-0-5".

Hi Pepetj,

The numbers are indeed N (Nitrogen)-P (Phosphorus)-K (Potassium).

The numbers represent the percentage of nutrients in the total volume of the fertilizer package.

So in your example

• Seachem's Flourish Nitrogen "1-0-2" contains roughly 1% Nitrogen, 0% Phosphorus and 2% Potassium
• Seachem's Flourish Phosphorus " 0-0.3-0.2" contains roughly 0% N, 0.3% P and 0.2% K
• Seachem's Flourish Potassium "0-0-5" contains roughly 0% N, 0% P and 5% K

What it is really telling you is you are getting precious little for your money.

The NPK can be a bit misleading and is designed and based on terrestrial plants.

However you see why most of us roll our own...
