Enhance nutrient uptake and prevent lockout - balance your pH with RAW Humic Acids.

RAW Humic Acids is 59% Humic Acids, derived from Leonardite - the most concentrated, water soluble humic acid around. 

It naturally buffers the pH of soils, keeping nutrient uptake high and preventing lockout. You can add it to RO water as a pH balancer. 

To increase nutrient uptake further, humic acid is a natural chelator. It really helps increase uptake of difficult minerals (e.g. iron, manganese & trace elements). Use this and you’ll get the best out of existing nutrients and additives.
