Verigrow is made in Western Australia from low grade wool waste.  It's a fertilser that provides nitrogen in a slow release form, and amino acids.

The benefits of amino acids for plants are numerous and have been studied by several research groups over the years. 

Amino acids help plants combat stress, increase root mass, activate natural defence mechanisms in plants, and enhance photosynthesis by increasing the chlorophyll concentration. They also promote nutrient absorption and stimulate the essential metabolic activities in the plant.

Amino acids also improve the beneficial microflora in various ways such as by strengthening the outer walls, allowing them to withstand harsher conditions. Happier, stronger microbial colonies help produce better nutrient uptake, as well as a more extensive and healthier root system that can fight diseases and maintain effectiveness in adverse environmental conditions.

It takes energy for plants to synthesise the amino acids required to create those cells. Providing plants with supplementary amino acids save plants energy, which they can utilise elsewhere. This helps maintain not only vigorous growth but pest and disease resistance as well.
