Age Old Kelp Sea Kelp Plant Supplement, 55 gal

Feed the Soil Life That Feeds Your Plants, 55 gal

Healthy plants start with a healthy root zone, but heavy synthetic feeding programs can quietly wear down the biological activity in soil that plants depend on for steady nutrient uptake. Age Old Kelp supplies a natural, fast-acting source of major nutrients made from Ascophyllum nodosum, a sustainably harvested, nutrient-rich sea kelp that increases biological activity in the soil rather than working against it.

Age Old Kelp ships in a 55 gal container, matched to commercial operations dosing at full scale.

Key Features & Benefits

• Made from Ascophyllum nodosum sea kelp — supplies a natural, fast-acting source of major nutrients harvested sustainably from the sea.
• Increases biological activity in the soil — helps build a living root zone that supports plants through every stage of growth.
• Aids in antioxidant production in plants — supports the plant's own natural response to everyday environmental stress.
• Supports seed germination — gives seedlings a stronger natural starting point early in the cycle.
• Improves nutrient uptake with natural chelators — helps plants make better use of the feeding program you're already running.

Who Should Use Age Old Kelp

Growers who want to support soil biology and overall plant vigor alongside their regular feeding program with a natural, sustainably harvested sea kelp supplement, whether running one room or several, with the 55 gal size matched to that scale.

About Age Old Nutrients Kelp

Age Old Nutrients, also sold as Age Old Organics, has formulated natural-based plant fertilizers since 1984, blending traditional growing practices with ingredient science for greenhouses, container gardens, and commercial cultivation. Kelp is built to complement rather than replace a base fertilizer program — many growers run it alongside Age Old Grow and Bloom to support soil biology and nutrient uptake through every stage, from early vegetative growth through flowering and fruit set.

Frequently Asked Questions

Can I use Age Old Kelp alongside Grow and Bloom?

Yes, Kelp is designed to complement a base feeding program, supporting soil biology and nutrient uptake alongside formulas like Age Old Grow and Bloom. It doesn't replace either one, since it carries a much lighter nutrient load by design.

What makes Ascophyllum nodosum different from other kelp sources?

It's a sustainably harvested, nutrient-rich sea kelp known for supplying a natural, fast-acting source of major plant nutrients and biostimulant compounds. That combination is why it's used as the base material across Age Old's Kelp formula rather than a generic seaweed extract.

Will Kelp help with seed germination?

Yes, it's labeled to support seed germination as well as overall biological activity and nutrient uptake in the root zone. Growers starting seed trays sometimes use a diluted Kelp drench during the earliest stage of the cycle for that reason.

How often should I apply Age Old Kelp during a growing cycle?

Most growers apply it on a regular schedule alongside their base feeding program, since its role is ongoing soil-biology support rather than a one-time treatment. Follow label dilution rates and adjust frequency to match how the crop is developing.

What's the NPK analysis of Age Old Kelp?

Kelp carries a light 0.30-0.025-0.015 analysis by design, since its role is to supply biostimulant compounds and support soil biology rather than serve as a primary feed. That's why it's paired with a higher-NPK formula like Grow or Bloom instead of used alone.
