With seedling tray or without?

Plastic or clay?

If you know that they are species that want direct light, such as fruit trees, garden plants, seasonal plants, etc., you can place it in full sun, but be careful: do not do it in summer because the temperature inside the germinator would rise too much, burning the seeds and cuttings you have planted.
