Description
BlackHūm is an organic humic‑acid additive that helps plants absorb micronutrients more efficiently through the root zone. Humic acid acts like a natural chelator, keeping essential nutrients available and helping the plant take them up more easily. This leads to healthier roots, stronger growth, and better overall performance in any growing system.
BlackHūm also supports a cleaner, more balanced substrate. It helps detoxify excess salts, heavy metals, and pesticide residues while improving water retention and buffering pH. This creates a more stable environment for roots to thrive.
What BlackHūm Does:
- Increases micronutrient uptake
- Supports a more active, healthier root zone
- Detoxifies salts, heavy metals, and pesticide residues
- Improves water retention in soil and substrates
- Helps stabilize pH for more consistent feeding
- Works in all growing media and hydroponic systems
Why It Matters:
Humic acid helps prevent nutrient lockout and keeps your feeding program running smoothly. When roots have access to clean, available nutrients, plants grow stronger, stay healthier, and respond better to your base nutrients.
How to Use It:
- Mix 1–2 mL per litre of water
- Use once per week or with every feeding
- Suitable for seedlings, vegetative growth, and flowering
- Adjust pH as needed
- Compatible with all micronutrients and rooting gels
- Can also be used as a foliar spray
What’s Inside:
- Soluble potash (0.5% K₂O)
- 10% humic acid derived from leonardite
- Derived from potassium hydroxide
Manufactured in Canada.
