Age Old Fish & Seaweed 3-3-2 Liquid Fertilizer, 6 gal

One Feed That Supports Growth, Flowering, and the Soil Underneath It

Running separate feeds for growth, flowering, and soil health can turn a feeding schedule into a juggling act — especially for growers who'd rather spend that time managing the rest of the garden.

Age Old Fish & Seaweed 3-3-2 blends ocean fish and seaweed extracts into a single, balanced formula designed to support vigorous plant growth, flowering, and fruiting in one application.

Beyond direct feeding, it increases biological activity in the soil and helps develop strong roots — naturally-derived nutrition that supports the whole system, not just the parts you can see.

Key Features & Benefits

• Blend of ocean fish and seaweed extracts — supplies a balanced, naturally-derived source of nutrition for growth, flowering, and fruiting.
• Increases biological activity in the soil — helps build a living root zone that supports plants through every stage.
• Helps develop strong roots — gives plants a sturdier foundation to draw on through the rest of the cycle.
• Excellent source of naturally-derived plant nutrients — rounds out a feeding program without relying on synthetic inputs.
• Aids in overall plant growth and yields — supports the kind of steady, well-rounded development that shows up at harvest.
• Sized for multi-room operations — this 6 gallon jug is built for growers feeding across more than one space.

Who Should Use Age Old Fish & Seaweed

Growers who want a single, naturally-derived feed that supports growth, flowering, fruiting, and soil biology together — well suited to multi-room operations looking to simplify a feeding program without giving up results.

Pairing Fish & Seaweed With a Base Feeding Program

Many growers run Fish & Seaweed alongside Age Old Grow, Bloom, or Kelp as a naturally-derived complement that rounds out the feeding program — supporting the plant directly while also building the soil biology those other formulas depend on for steady uptake.
