Roots Organics Extreme Serene is a natural source of growth-promoting nutrients and botanical extracts. Our revolutionary new formula improves upon the original: We have targeted and isolated crucial components in various kelp species and stabilized the solution for maximum absorption.
Extreme Serene captures the fast-growing power of marine kelp to encourage vigorous shoot and root growth. Use Extreme Serene in conjunction with any nutrient program or as a foliar feed.
