Humic Tonic

Growth Science Humic Tonic is a humic acid concentrate from Growth Science Nutrients, providing concentrated leonardite-derived humic and fulvic acids in a convenient liquid tonic format for cannabis cultivation. The Tonic format is designed for easy mixing into irrigation water or reservoir systems — a small amount delivers significant humate inputs per application.

Humic acids improve mineral bioavailability through chelation, enhance root permeability, stimulate beneficial microbial populations, and improve the physical characteristics of growing media. Regular application creates a progressively more fertile root zone environment.

Apply throughout the grow cycle per Growth Science's recommendations. Made by Growth Science Nutrients, US.
