Do a pre-soak on your rockwool cubes and plant the seeds directly inside (about 1 cm deep), put the cubes in a tray and close the lid/dome. With the right temperature, seeds should germinate quickly, usually between 24-72 hours. Once seeds have germinated and have started developing roots (about 2 weeks), the rockwool cubes can be placed in your chosen grow medium (e.g. soil). Hope this helps!
