Know before you buy
Humic acid acts as a soil conditioner that improves the structure of your soil and makes existing nutrients more accessible to plant roots. By stimulating beneficial microbial activity, it creates a healthier environment for plants to thrive.
Yes, this product is safe and effective for indoor plants. Because it is a concentrated liquid, be sure to follow the dilution instructions carefully to avoid over-fertilizing your potted plants.
Leonardite is a highly oxidized form of organic matter and is considered the gold standard for humic acid extraction. Using 100% pure leonardite ensures a high concentration of bioactive compounds, making the treatment more effective than those derived from lower-quality organic sources.
No, this is a soil amendment, not a fertilizer. It helps your plants use the nutrients already present in your soil or fertilizer more efficiently, but it does not provide the primary nitrogen, phosphorus, and potassium (NPK) that plants need for basic growth.
For best results, apply it periodically throughout the growing season to maintain soil health. We recommend checking the label for specific application intervals, as frequency can vary based on your soil type and the specific needs of your vegetables.
