Cretaceous Period Fresh Water Humic Substances

Down To Earth™ HumaPlex™ is water soluble and effective in soil applied, hydroponic, irrigation and fertigation applications.

Note: Always pre-mix HumaPlex™ before using by creating a concentrated solution then adding to your total volume of water needed for coverage. About 15% is insoluble and can be recycled. Mix measured dry product with water, wait for a few minutes to allow settling and then pour off humic acid solution for desired application. Discard remaining sediment in garden, landscape or compost.

Vegetable Gardens & Flower Beds:

For soil applied solutions, mix ⅛ – ¼ tsp. (0.5-1.0 gm) per gallon of water and apply around the base of established plants. For dry broadcast, apply ⅛ – ½ cup (1-3.5 oz.) per 1000 square feet. Apply three to four times throughout the growing season or as needed.

Compost Tea:

Add ¼ tsp. (1.0 gm) per gallon of water prior to brewing to fortify and enhance biological activity.

Hydroponics:

Use ⅛ – ¼ tsp. (0.5-1.0 gm) per gallon of reservoir nutrient solution. Use with every change. Top-offs can be added at half the normal rate.

Trees, Shrubs & Vines:

For soil applied solutions, mix ½ cup (100 gm) in 25 gallons of water and apply around the base of established plants or inject into surrounding soil. Apply two to three times throughout the growing season or as needed.

Compost Tea:

Add ¼ tsp. (1.0 Turf: For dry broadcast, apply ⅛ – ½ cup (1-3.5 oz.) per 1000 square feet. Apply three to four times throughout the growing season or as needed. First application should be in early spring and last application should be in late fall. Results may be enhanced if applied following aeration.

STORAGE: Keep container tightly sealed. Store in a dry, cool place.

Note: Exceeding application rates can cause irregular growth patterns. HumaPlex does not replace fertilizers.
