For over 12 years, Island Organics has specialized in producing Seaweed Biostimulant Extract that helps farmers, nurseries ,greenhouse growers reduce input costs while boosting crop health, resilience, and yield.

Our mission is to provide fresh Ascophyllum nodosum seaweed and hands-on training to establish a simple, reliable, on-site brewing process for OMRI listed seaweed extract.

We sustainably harvest seaweed from Penobscot Bay in mid-coast Maine and deliver it directly to brewing location This avoids the high cost of premade inputs while ensuring quality control and supply. Seaweed is naturally rich in plant growth regulators (PGRs) and systemic acquired resistances (SARs), which improve crop health and yield. we typically see a 15-20% increase in yield and stronger plant health!

Here’s how it works:

This system allows growers to cut costs, improve yields, and build long term soil health – all with a sustainable, OMRI approved input.


Sustainably hand harvested ASCOPHYLLUM NODOSUM seaweed from the pristine coastal Maine waters. Packed fresh in mesh bags and stored in ocean water to keep the seaweed nutrient-rich until transport 

Bags are rinsed with fresh water to remove any excess salt.
Each bag is weighed for the right ratio’s needed for size of batch being brewed before shipping to the brewing location

Clean, fresh seaweed is delivered directly to location by truck in bags.
Tractors are used to unload the seaweed efficiently for processing.

The seaweed bags are placed into large pools for controlled brewing. Bags are opened and the seaweed is released into pool. The biomass begins to breakdown, starting the natural fermentation. This system allows for fermentation and nutrient release that turns into a biostimulant.

The seaweed ferments over 30 to 40 days, gradually transforming into a concentrated biostimulant. Aeration encourages microbial activity, producing natural PLANT GROWTH REGULATORS (pgr’s) and SYSTEM ACQUIRED RESISTANCE (sar’s) compounds .
The foaming action shows enzymes and microbes working to release nutrients.

After brewing, the liquid is filtered with 200 micron filters ensuring no clogging issues on drip lines or foliar spraying. The end result is a nutrient rich organic extract full of minerals, amino acids, cytokinins, auxins, and natural stimulants .

The leftover seaweed in the end of process is used as a great soil conditioner, so there is zero waste with the process.

OMRI listed for organic growing , suitable for soil, hydro, and foliar feeding.

growers receive a cost-effective powerful biostimulant that boosts yields, strengthens crops, and improves soil health.

1. Space for Brewing Pool

  • A flat, stable area to place the pool or tank
    (30-40 day brewing process).
  • Should allow safe access for filling,
    monitoring, and filtering.
  • Ideally shaded or partially covered to
    protect from debris.

2. Reliable Water Source

Clean and consistent water supply is
needed for:

  • Filling the pool
  • Rinsing equipment
  • Maintaining brewing conditions

Connection point should be within easy
reach of the pool.

3. Electrical Access (220V Power)

Standard 220V outlet required for:

  • Pumps
  • Mixers
  • Filtration systems

Power source should be stable and near the brewing location.

Note: These are the only essentials needed from the brewing location We provide the seaweed, brewing expertise, and setup guidance to make sure the process runs smoothly.
