Product Information

One of the most important aspects of your garden is the nutrients added to the system. Nutrients play an important part in your plants life cycle and provide all the essential macro and micro elements that are needed to have a strong structural foundation. Without these nutrients, a plant will be unable to complete its life cycle. Whether you’re a hobbyist or a commercial gardener, having the right nutrient will guarantee you achieve the very best out of your garden.

The Professor’s Original Nutrient offers a complete solution for both the Grow and Bloom cycles without the need to buy separate Grow and Bloom formulations. The unique formula is made with quality chelated elements, enabling plants to process them efficiently and ensuring great results in all stages of plant growth. Made under strict quality controls using only the highest grade minerals and trace elements, guaranteeing the highest possible quality and nutrient absorption.

  • Designed for both indoor and outdoor gardening.
  • Suitable for Rockwool, Perlite, Vermiculite, Expanded Clay, Coco Fibre and Soil.
