Roots Organics Extreme Serene Kelp-Based Liquid Plant Food & Fertilizer, 2.5 Gal

Roots Organics Extreme Serene is a premium liquid plant supplement formulated to support vigorous growth, healthy foliage, and improved plant resilience. Built on a foundation of botanical extracts, this advanced formula features a rich blend of seaweed extracts (Ascophyllum nodosum, Chondrus crispus, Ecklonia maxima, Laminaria digitata, and Palmaria palmata), combined with spirulina and triterpene saponins derived from Quillaja saponaria. These ingredients work synergistically to promote strong plant development, healthy root systems, and vibrant, green foliage.

Extreme Serene is a natural source of plant nutrients and growth-promoting compounds. The formula isolates key elements from select kelp species and stabilizes them to ensure maximum nutrient availability and absorption. Use it alongside any nutrient program or as a foliar spray, just mix, apply, and watch plants respond with renewed vitality.

With a gentle 0.25–0.1–2 NPK ratio, it provides mild support that’s ideal for early vegetative growth, clones, mother plants, and stressed or yellowing foliage. It can also be watered into the root zone for similar benefits, making it a versatile solution for both recovery and ongoing plant care. Extreme Serene from Roots Organics integrates seamlessly into any feeding schedule as a universal additive to improve overall plant performance.
