Why it matters
Stress is lost yield.
Heat, transplant, a hard week — every stress event costs growth. Seaweed keeps the plant and the soil steady so it never drops a beat.

What’s in the bottle
One kelp. Put to work.

Durvillaea potatorum Southern bull kelp
A single brown kelp from the cold Southern Ocean off southern Australia carrying alginates and potassium — the base that keeps growth even and buffers stress from seedling to bloom.
