Farmtek NPK Fertilizer 13-7-40 Commercial Grade
100% Water Soluble
with Trace Elements [Potassium Focused]

Commercial Grade NPK Fertilizer

Farmtek professional grade soluble NPK fertilizer is suitable for any grower of any type (indoor or outdoor) looking to add some great nutrients to their plants. NPK stands for Nitrogen (N), Phosphorus (P), and Potassium (K). These are the three main ingredients that make up all plant food. This 13-7-40 ratio produces a highly concentrated, balanced combination of nutrients your plants need to thrive!

NPK fertilizers typically come in three forms: powdery, diluted liquid, and granular pellets. The powdery form of NPK has the highest concentration ratio, and broader application methods, and is the most economical form of fertilizer for the fruiting stage.


Product Properties

100% water soluble, suitable for drip irrigation, foliage spray, hydroponics solution, and liquid fertilizer.

Nitrogen (N) 13 : Phosphorus (P) 7 : Potassium (K) 40

Trace Elements:

Nitrate Nitrogen (≥6%), Fe (0.1%), Zinc (0.05%), Mn (0.05%), Mo (0.01%), B (0.05%), TE (0.25-1)

Nitrogen (N) is important for producing chlorophyll, which allows plants to turn sunlight into food. It is the most important nutrient for plant growth. Without nitrogen, plants cannot make chlorophyll, the green pigment that makes photosynthesis possible. Chlorophyll enables plants to produce carbohydrates and proteins needed for plant growth.

Phosphorus (P) encourages the growth and strength of stems, flowers, and roots. Phosphorus is critical to photosynthesis because it works with nitrogen to create proteins and enzymes that help the plant make energy from sunlight. The major function of phosphorus is to help a plant develop strong root systems and healthy leaves. Plants require more phosphorus than nitrogen or potassium because it is a structural component in plants. It also helps plants produce seeds and fruit while they are growing and maturing fruits, tubers and root crops.

Potassium (K) is one of the three key nutrients that plants need to grow. It aids in supporting a plant’s metabolism by regulating the movement of water, nutrients and minerals throughout the plant tissue. Most foliage plants, including those in cacti and succulent collections, contain elevated potassium levels. In fact, all fertilizers should have this element included in some form. It helps to improve plant growth and boosts the rate of photosynthesis through its effect on chlorophyll production.

This fertilizer contains 13-7-40 NPK as a three-part combination fertilizer with a balanced ratio of nitrogen, phosphorus, and potassium to promote healthy growth.
