Roots Organics Extreme Serene Quart

Roots Organics Extreme Serene is a natural source of botanical extracts and nutrients for plant growth. Our revolutionary new formula improves upon the original: We have targeted and isolated crucial nutrients in various kelps and other seaweed species and stabilized the solution for maximum absorption. Extreme Serene captures the growing power of diverse seaweeds to improve conditions for vigorous shoot and root growth. Use Extreme Serene in conjunction with any nutrient program or as a foliar feed.

This is by far one of the best liquid kelp products we've ever seen.
Combines Ascophyllum Nodostrum, Chondrus Crispus, Ecklonia Maxima, Laminaria digitata, Palmaria palmata (ALL of the kelp/seaweed varieties), and Spirulina.
Hands-down the most diverse mix of kelp species offered up in 1 convenient bottle.

Highly recommended.
