Luce
Bright, 12–14 h; it grows leggy in too little light.
Irrigazione
Keep constantly moist, never dry out — cress only germinates and grows with steady moisture.
Temperatura
15–22 °C; cool and fast, heat makes it bitter.
Umidità
55–70 %, higher during germination.

Problemi comuni
Damping-off (Pythium) when too warm-wet and sown densely; mould in still air. Sow thinly and ventilate.
Pests & diseases
| Pest / Disease | Symptom | Organic treatment |
|---|---|---|
| Flea beetles | tiny holes in leaves (outdoors) | fleece cover, keep moist |
| Damping-off | seedlings collapse | avoid overwatering, good airflow |
Edible parts
- Leaves · edible from Piantina — as microgreen/sprout
- Seeds · edible from Fruttificazione
Tecniche di resa
Cut just above the substrate with scissors once the first true leaves appear — usually a single harvest, then re-sow.
