Made from Ascophyllum Nodosum Seaweed

The foundation of Nutri+ Seaweeds is a concentrated extract of Ascophyllum nodosum, a brown seaweed commonly used in horticultural seaweed products.

Nutri+ sources its kelp from cold-water environments and processes it into a concentrated, completely water-soluble liquid extract. This makes it easy to dilute into irrigation water or prepare as a foliar application without leaving growers with a difficult-to-mix solid product. 

Potassium-Rich 0-0-5 Formula

Nutri+ Seaweeds carries an NPK analysis of 0-0-5, providing potassium without adding significant nitrogen or phosphorus.

Potassium is an essential macronutrient involved in many plant processes, including water regulation, enzyme activity and overall plant development. Because Seaweeds contains no listed nitrogen or phosphorus in its guaranteed NPK ratio, growers can incorporate it as a supplement alongside a complete base fertilizer rather than replacing the primary nutrient program.

This makes Nutri+ Seaweeds (0-0-5) especially useful for growers who want the benefits of a seaweed-based supplement without substantially increasing nitrogen or phosphorus levels.

Supports Root Development

Growers have long incorporated seaweed extracts into horticultural programs to support plant establishment and root development. Nutri+ specifically lists root growth among the intended benefits of its Seaweeds formulation.

A healthy root system helps plants explore a larger volume of growing media for water and nutrients. For this reason, Nutri+ Seaweeds can be particularly useful when plants are establishing in new containers or growing media.

Useful During Transplanting & Propagation

Nutri+ Seaweeds is also designed to support seed germination, transplantation and the development of cuttings and branches as part of a complete growing program.

This makes the product easy to incorporate into propagation and transplanting routines where growers want to provide supplemental seaweed compounds and potassium while young plants are establishing themselves.

It can be used alongside a suitable rooting, propagation or base nutrient program depending on the plant’s stage of development.

Complements Nutrient Uptake

Nutri+ Seaweeds is intended as a supplement to a complete fertilization program, rather than as a stand-alone fertilizer. The manufacturer highlights support for soil mineral uptake and micronutrient nutrition among its traditional horticultural applications.

This makes Seaweeds a practical addition for growers already using a balanced base nutrient program and looking to incorporate a kelp-based supplement without completely changing their feeding schedule.

Supports Chlorophyll Production & Plant Development

Nutri+ also identifies chlorophyll production as one of the horticultural functions associated with its Seaweeds product.

Chlorophyll is essential for photosynthesis, allowing plants to capture light energy and use it to produce carbohydrates.

When used as part of a properly balanced nutrient and environmental program, Nutri+ Seaweeds provides additional potassium and seaweed-derived compounds to complement healthy plant development.

Fully Water-Soluble Liquid Formula

A major advantage of Nutri+ Seaweeds is that the liquid kelp extract is completely water-soluble.

This lets you easily dilute the concentrate into irrigation water and makes it suitable for a variety of growing systems.

The liquid format also eliminates the need to dissolve dry seaweed powders before application, making it convenient for growers who prefer straightforward mixing and dosing.

Suitable for Indoor, Outdoor & Hydroponic Growing

Nutri+ Seaweeds is designed for a broad range of cultivation methods, including:

• Indoor gardens
• Outdoor gardens
• Container plants
• Hydroponic systems
• Soil cultivation
• Soilless growing media
• Greenhouse production

The current product directions specifically identify pots, indoor and outdoor gardens and hydroculture as suitable applications.

This versatility makes it easy to incorporate Seaweeds into different growing environments without requiring a separate kelp supplement for each cultivation method.

Irrigation Application

For irrigation, dilute:

1 to 3 ml of Nutri+ Seaweeds per litre of water.

Select the exact amount within that range based on the crop, growth stage, and overall feeding program.

Mix the product thoroughly into the irrigation water before application.

Because Seaweeds is intended as a supplement, use it alongside an appropriate base fertilizer when complete plant nutrition is required.

Foliar Application

You can also apply Nutri+ Seaweeds as a foliar spray.

For foliar use, dilute:

1 ml of Nutri+ Seaweeds per litre of water.

Apply the diluted solution evenly to plant foliage, according to the crop's needs.

Do not apply the foliar solution in full sun.

Applying foliar products away from intense direct light can help reduce unnecessary stress on wet foliage.

How to Use Nutri+ Seaweeds (0-0-5)

Dilute 1 ml per litre of water and spray evenly onto foliage.
