Agron Has the Nutrient Supplements You Need

Fertilizers and nutritional supplements are important for indoor plants. Because they are not receiving nutrients from an outdoor environment, supplementation is often necessary for healthy plant growth. At Agron, we understand your concern over being able to harvest healthy plants. We offer a wide range of products to meet the nutritional needs of all indoor plants.

Why Are Nutrient Supplements Important for Indoor Plants?

Just like humans, plants are constantly undergoing cellular processes and they need the right nutrients to ensure they can grow healthy and strong. There are six essential nutrients that are needed by all plants and they include the following. 

  • Nitrogen
  • Phosphorous
  • Magnesium
  • Potassium
  • Calcium
  • Sulfur

If indoor plants are not receiving the nutrients they need, growers will see changes in the health of their crops. A lack of nutrients affects plant growth from the root level to the foliage. With the right fertilizer and nutrient supplements, growers can rest assured their plants will have all the nutrients they need for healthy growth and development.

How Can Growers Supply Their Plants with Vital Nutrients?

Agron carries a wide array of nutrient supplements and fertilizers to help indoor growers see the biggest and healthiest yields. No grower wants to put in a lot of time and effort, only to end up with a lackluster harvest.

Thankfully, nutrients can be added to the growing soil or medium. They can also be added to the water source of a hydroponic growing system. It is important growers understand the needs of their plants and how to properly administer any nutrient supplements. Agron offers a large assortment of the best nutrient supplement brands on the market. As always, we are available if you need any assistance with any of these products.
