NPK ranges

[floydbraido]

I see NPK's that range from 1 to +50. So what exactly does low, medium, high. Is 20 medium, high or what?

Hey floydbraido Do a search on the GWE website about nutes. There are recommendations for great weed products.

The numbers after the NPK are the percent amounts of each nutrient.

An NPK value of 10-5-5 means that the fertilizer contains 10% nitrogen, 5% phosphorus and 5% potassium.

good luck
