During germination, the seed awakens from its inactivity.
Water is essential here, for as soon as the seed has absorbed a sufficient amount of water, the seedling begins to form its root system.
Next it breaks through its shell. There are various possibilities for the process of germinating:

Put some moist tissues on a plate.
Put the seeds on top of them and then put a layer of moist tissues on the seeds.
Cover the plate with another upturned plate, so that the seeds are in darkness and the environment remains moist.
Put the covered seeds in a warm place
( 21°C ). Check the seeds everyday, sprinkle the tissues if necessary and carefully transplant the seeds when they open and the tip of the root becomes visible.
Put the seed in a growth medium ( soil or rockwool ), approximately the size of the seed under the surface ( approx 5mm ).
Carefully cover the opening.

The seedling uses the spare food present in the seed for growing.
Air is very important for its metabolism.
So make sure that the soil remains sufficiently airy.
One of the characteristics of rockwool is that it retains much air.

Make sure that the rockwool is not standing in water and that the excess water is able to drain away properly.

Rockwool has a fine germination climate for the seeds.
Keep the seeds warm ( 21°C ) and moist, for example in a propagator.
Remove the cover as soon as the seedlings reach above the medium.

The young plants are still very delicate. Therefore you should not place them in direct sunlight or just below a grow lamp.

This might cause burning. Provide young plants with nutrient water with a low EC value ( 1.2 ) and add a booster to strengthen the root system.
