Water quality

The water does the fertilizing

We add nothing. Kelp drinks the same nitrates that fuel spring blooms, so we never dose a line. Our job is to watch the chemistry and stay out of its way.

nitrate      5–20 µmol/L
salinity     30–34 ppt
turbidity    low
temp         < 15 °C

What we watch for

Warm spikes are the real enemy — a few weeks above 15 °C and the blades start to break down. When the sensors show it, we harvest early and save the crop.
