Neptune's Harvest Seaweed Plant Food 0-0-1 | 1gal - Concentrate - Makes 128gal - OMRI Listed - (Case of 4)

North Atlantic Seaweed Concentrate for Alternate Feedings, 1gal

A straight fish fertilizer covers nitrogen and phosphorus, but doesn't add the micronutrients and growth compounds that seaweed alone contributes between regular feedings. Neptune's Harvest Seaweed Plant Food 0-0-1 is made from Ascophyllum Nodosum harvested along the cold North Atlantic ocean floor, meant to be used as an addition to a regular fish fertilizer program.

This 1gal concentrate makes up to 128gal of solution and is recommended for use on plants in alternate feedings alongside a fish fertilizer program, and is OMRI Listed.

Who Should Use This Seaweed Concentrate

Growers running a regular fish fertilizer program who want to add a seaweed-based product in alternate feedings for extra micronutrients and growth compounds.

Frequently Asked Questions

What is Seaweed Plant Food made from?

Ascophyllum Nodosum, a seaweed harvested along the cold North Atlantic ocean floor. That cold-water sourcing is specific to Neptune's Harvest's seaweed line.

How do I use it?

Use it on plants in alternate feedings alongside a regular fish fertilizer program rather than as a standalone feed. Alternating between the two is how the product is designed to be used.

Is it OMRI Listed?

Yes, across all three case sizes. That listing applies to the concentrate before dilution.

How much solution does one unit make?

Each size states its own yield: the 16oz size makes up to 16gal, the 32oz size makes up to 32gal, and the 1gal size makes up to 128gal. Yield scales directly with concentrate volume.

Which size should I choose?

The 16oz and 32oz cases of 12 suit growers who want smaller batches ready more often, while the 1gal case of 4 suits growers mixing larger volumes less frequently. All three dilute at the same concentrate-to-water ratio.
