Age Old Kelp Sea Kelp Plant Supplement, 55 gal

Feed the Soil Life That Feeds Your Plants

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.

Beyond feeding the plant directly, it aids in antioxidant production, supports seed germination, and improves nutrient uptake through natural chelators — work that shows up as steadier growth over a full cycle.

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 defenses against everyday 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.
• Sized from 1 to 55 gallons — lets growers match the bottle to their garden, from single rooms to commercial operations.

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.

Adding Kelp to an Existing Feeding Program

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.

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.

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.

What's the NPK analysis of Age Old Kelp?

Kelp carries a light 0.30-.025-.015 analysis by design — its role is to supply biostimulant compounds and support soil biology rather than serve as a primary feed.
