Emerald Harvest Grow is responsible for increasing sugar content - producing larger, sweeter, and higher-quality fruits and flowers in the blooming stage.


3-part mix

Complement this nutrient mix with its partners Micro and Bloom, specially designed to work together and achieve superior growth in all areas. Grow focuses on enriching potassium and phosphorus, stimulating plants’ ability to break down and utilise nutrients to their full potential. 


Supplies essential potassium

It’s no secret that potassium is one of the main components in forming lush leaf canopies and strong plant structures. Grow contains three different types of potassium, each with a different job - so you’ll see impressive results all round.


  • Monopotassium Phosphate is vital for root development. It also increases sugar content for deliciously sweet-smelling and -tasting fruits and flowers.

  • Potassium Sulphate improves plant quality, as well as boosting the amino acids that are needed to form proteins (including glutamic acid, aspartic acid, and alanine). The proteins formed are necessary building blocks for germination and rapid early growth. 

  • Magnesium Sulphate is essential for photosynthesis and helps to increase yields. 


Flexible formula

Sometimes, you’ve got to go with the flow. The “Grow, Micro, Bloom” 3-part mix is designed to be flexible. Identify your plants’ needs and adjust the dosages accordingly.


If your garden needs a little help, slightly increasing Grow will get you on the way to achieving optimal size and yields.
