Description
Why Humic Acid
- Supports healthier plants by increasing nutrient uptake and preventing nutrient lockout (Arancon et al. 2006, Pettit)
- Makes micronutrients more bioavailable so plants are able to access more of what they need (Arancon et al. 2006, Pettit)
- Reduces leaf yellowing caused by iron deficiencies by increasing iron uptake by up to 161% (Arancon et al. 2006)
- Enhances plant’s natural defenses by binding to disease-causing agents
- Stabilizes pH and allow plants to function in a wider pH range (Pettit)
- Improves soil water retention
- Breaks up compressed, clay-heavy, soils (Pettit)
Ingredients
Humic acid extract (Humic Content: > 60% Fulvic Content: > 15%)
How to Use
Hydroponic: Add 1/8 to 1/4 tsp per gal in reservoir
Soil: Add 1-2 teaspoons per gallon of soil
