Roots Organics Extreme Serene, 5 gal

Stabilized Kelp Extract for Shoot & Root Growth, 5gal

Kelp is one of the most reliable botanical inputs for supporting new shoot and root growth, but raw kelp meal can be slow to release and inconsistent from batch to batch. Roots Organics Extreme Serene isolates the nutrients that matter most from a range of kelp species and stabilizes them in liquid form, so every application delivers a consistent, readily absorbed dose.

This 5gal size suits growers with a larger container count who feed weekly and want fewer refills over a full season.

Key Features & Benefits

• Multi-species kelp sourcing — targets nutrients from several kelp species rather than a single source
• Stabilized liquid form — keeps the isolated nutrients in a consistent, readily absorbed state from bottle to bottle
• Shoot & root support — improves growing conditions during both above- and below-ground development
• Foliar or root-zone use — works as a foliar spray or mixed directly into an existing nutrient program

Who Should Use Roots Organics Extreme Serene

Growers who already run a base nutrient program and want a botanical kelp addition for stronger shoot and root development, without switching feed lines, fit Extreme Serene well.

About Roots Organics

Aurora Innovations has built the Roots Organics catalog of soils, amendments, and nutrients from Eugene, Oregon since 2000, drawing many of its botanical inputs, kelp included, from marine and plant-derived sources rather than synthetic salts.

Frequently Asked Questions

What is Extreme Serene made from?

It's a liquid concentrate of botanical extracts and nutrients isolated from several kelp species. The formula is stabilized to keep those nutrients consistent and readily absorbed between bottles.

How is it applied?

Extreme Serene can be mixed into any existing nutrient program or applied as a foliar feed directly to leaf surfaces. It's designed to layer onto a base program rather than replace it.

When during the grow cycle should I use it?

It supports both shoot and root growth, so it's suited to vegetative and early flowering stages when a plant is actively building new tissue above and below the soil line. Growers commonly work it into a weekly feeding routine during those active-growth windows.

Why kelp specifically?

Kelp naturally carries a wide range of growth-supporting compounds, and isolating them from multiple species gives a broader nutrient profile than relying on a single kelp source. That breadth is why it's used as a general vigor additive rather than a stage-specific bloom or grow product.
