Water Quality
As a leaf crop, water quality matters directly — keep salinity low and water clean.

Fertilization
Steady nitrogen supports leaf growth, but avoid excess (nitrate accumulation and soft leaves); fertigate little and often.

q.wave Perspective
For a leaf you eat, clean and consistent water is a quality issue, not just a yield one. q.wave conditions water non-chemically and complements — does not replace — proper water treatment.
