HUMBOLDT DeuceDeuce

DeuceDeuce is a potassium additive derived from sulfate of potash and Ascophyllum nodosum seaweed. For use in Soil growing medium.

Potassium aids plants in enzymatic function, protein and cellulose formation, efficient photosynthesis and rapid transportation of carbohydrates and starches throughout a plant’s vascular system.
Providing high levels of potassium to your plants will also harden flowers and improve overall plant health.

When DeuceDeuce is diluted and mixed in water a beneficial environment for biological life is created.
This unique blend allows helpful biological activity to immediately begin breaking down the elements provided by the high quality, cold pressed Ascophyllum nodosum.
Using DeuceDeuce in conjunction with Grow Natural and Bloom Natural can allow your plants to reach their peak performance.
Our customers currently using DeuceDeuce have reported these results: increased root growth, lush vegetation, larger and harder flowers and improved overall quality for all the plants in their gardens.
