NPK Industries RAW Humic Acid - 25 lb

Humic Acid Supplement for Soil and Hydroponic Feeding - 25 lb Bag

Nutrient programs work best when the root zone stays balanced and nutrients stay available to the plant. This humic acid supplement is derived from leonardite, acts as a natural chelator, and fits into an existing feeding schedule without changing your base nutrients.
