GPF uptake is essentially a liquid fulvic acid or humid acid. Fulvic acid stimulates enzyme production which is important for basic plant functions including increasing the content of chlorophyll and the respiration rate. GPF helps move vital yield enhancers and nutrients to where they are needed most. It also has a stabilising benefit and acts as a buffer against rapid movements in pH levels. 

GPF is sourced from Humalite which is the most beneficial source of humid acid for use in agriculture. It is an essential component and can be used in any nutrient regime as well as being used as a foliar spray of increasing resin content.
