Nutrients


Nutrition is a key component of growing tropicals indoors. Here at GrowTropicals, we've hand-selected our favourite synthetic and organic fertilisers and amendments. We use all the brands, including Hesi and BioBizz, day to day in our nursery too, ensuring you receive products which are tested rigorously with the plants we offer. 

Nitrogen, potassium and phosphorus are the bedrock of fertilising and known as the primary nutrients. Alongside NPK, calcium, magnesium and sulphur, also known as secondary nutrients, are key to healthy plant growth. But beyond both these groups, you’ve also got the group termed micronutrients, that’s things like Boron, Zinc, Manganese, Iron, Copper, Chlorine and Molybdenum. So it’s important to ensure your plant is receiving all the nutrients required.

All our products are selected because they offer a full range of plant nutrients to ensure your plant thrives, achieves unrivalled growth and to prevent any issues with nutrient deficiencies

      Essential Nutrients for Healthy Growth

      Nitrogen, potassium, and phosphorus form the bedrock of fertilising and are known as the primary nutrients essential for plant growth. These nutrients play crucial roles in various plant functions, from leaf development to flowering and fruiting. Alongside NPK, calcium, magnesium, and sulphur—known as secondary nutrients—are vital for supporting healthy growth and strengthening plant structure.

      Comprehensive Nutrient Solutions

      Beyond primary and secondary nutrients, micronutrients such as boron, zinc, manganese, iron, copper, chlorine, and molybdenum are essential for overall plant health. These micronutrients, although required in smaller quantities, play critical roles in plant metabolic processes and enzymatic functions. It’s important to ensure your plant is receiving a balanced supply of all these nutrients to prevent deficiencies and promote vigorous growth.
