buoy™ PRO Soluble Seaweed Powder 0-0-18

OMRI Listed Organic · Wild-harvested Maine seaweed · Made in USA · Dissolves completely — no clogging

All the power of Maine seaweed. No liquid to ship.

buoy™PRO Soluble Seaweed Powder delivers the same wild-harvested Ascophyllum nodosum biostimulant activity as our liquid extract — in a concentrated, fully water-soluble powder format designed for commercial operations, hydroponic systems, and growers who want lower shipping weight and longer shelf life without sacrificing performance.

With a 0-0-18 analysis, it delivers a meaningful potassium boost alongside the full spectrum of naturally occurring seaweed bioactives — the cytokinins, auxins, betaines, and alginates that make Ascophyllum nodosum the most studied biostimulant species in agricultural science.

Why powder over liquid?

 — Longer shelf life

— 3 years vs 2 years for liquid

— Won't freeze or degrade in cold storage or shipping

— Lower shipping weight 

— significantly more cost-effective at larger volumes 

— Dissolves completely 

— no clogging in drip lines, injectors, or boom sprayers 

— Ideal for hydroponic reservoirs where clean dissolution is critical 

— Easy to weigh and measure for precise application rates

What it does:

— Stimulates root development and lateral root branching

— Activates soil microbial communities and mycorrhizal networks 

— Improves plant tolerance to drought, heat, frost, and transplant shock 

— Supports consistent fruit set and reduces stress-related blossom drop 

— Improves nutrient uptake efficiency from existing soil fertility programs 

— Compatible with most fertilizers, pesticides, and herbicides

How to use:

General use (soil drench or foliar): Mix ¼ tsp per gallon of water. Apply every 2–3 weeks through the growing season.

Transplanting: Mix ½ tsp per gallon, apply as a root drench at planting to reduce transplant shock.

Hydroponics: Add ¼ tsp per 5 gallons of reservoir solution when refreshing. Compatible with most nutrient programs.

Boom sprayer / commercial: Mix at 2–4 oz per 100 gallons. Apply at transplant, early vegetative, flowering, and fruit set.
