Packaging

Sowing method: The seeds germinate quickly. Keep them evenly moist (not wet) at approx. 20°C. Cover seeds only thinly; fine seeds should not be covered but lightly pressed. Place a box or dark cloth over them, as they are not light germinators. Immediately after emergence, move them to light and a cooler spot.
