Hum-bolt humic HPS The GrowBoss Nutrient Monitoring SystemLiquid Humic Concentrate HUM BOLT HUM BOLT is a 8% humic acid derived from premium Leonardite, extracted from a mine known to produce the highest quality shale. Humic acid promotes high ion exchange capabilities, stimulates plant enzymes, increases beneficial organisms, and acts as an organic catalyst. For years humic acid has been largely absent from our soil, due to erosion and overfarming, and its benefits have been overlooked for far too long.
