Take any tree, shrub, plant or grass, remove the water from it and you will find they consist mainly of Nitrogen (N), Phosphorus (P) and Potassium (K), known as NPK.

Plants require and take up NPK in larger quantities than any other nutrients, so along with water, light and CO2, NPK levels have more leverage over the growth of your plants than anything else we know of.

Available pre-mix nutrient programs deliver time tested levels of NPK that produce great results, so we analyzed the nutrient content of many of them to develop a good view of what a top producing nutrient profile looks like for Cannabis and how they can be easily reproduced using cost effective mainstream horticulture practices and materials.
